  • Pass variable to Info Window in FusionTableLayer

    - by user1030205
    I am building a web application that includes a Google Map layered with data from a Google Fusion Table. I have defined the info window for the markers in the Fusion Table and all is rendering as expected, but I have one issue. I need to pass a session variable from my web application to be included in the links that are defined in the info window, but can't seem to find a way to do this. Below is the javascript I am currently using to render the map: var myOptions = { zoom: 10, mapTypeId: google.maps.MapTypeId.ROADMAP, center: new google.maps.LatLng( 40.4230,-98.7372) } map = new google.maps.Map(document.getElementById("map_canvas"), myOptions); // Weather weatherLayer = new google.maps.weather.WeatherLayer({ temperatureUnits: google.maps.weather.TemperatureUnit.FAHRENHEIT }); weatherLayer.setMap(map); //Hobby Stores var storeLayer = new google.maps.FusionTablesLayer({ query: { select: "col2", from: "3991553" }, map: map, supressInfoWindows: true }); //Club Sites var siteLayer = new google.maps.FusionTablesLayer({ query: { select: "col13", from: "3855088" }, styles: [{ markerOptions: { iconName: "airports" }}], map: map, supressInfoWindows: true }); I'd like to be able to pass some type of parameter in the call to google.maps.FusionTableLayer that passes a value to be include in the info window, but can't find a way to do this. To view the actual page, visit www.dualrates.com. Enter your zipcode and select one of the airport markers to see the info window. You may have to zoom the map out to see an airfield.

  • Adding extra data to a Variable

    - by DogPooOnYourShoe
    Right now, my code plucks out only one value using Mysql. So I thought I might aswell add each found result to a variable, however I dont know how to do this. This must be a very basic question, but I cant find a answer for it echo '<table border="1">'; echo "<tr><td><b>Surname</b></td><td><b>Title/Name</b></td><td><b>Numbers</b></td><td><b>Telephone</b></td><td><b>Edit</b></td><td><b>Del</b></td></tr>\n"; while ($row= mysql_fetch_array($result)) { $Surname = $row["Surname"]; $Title = $row["TitleName"]; $Email = $row["Email"]; $Telephone = $row["Telephone"]; $id = $row["id"]; $MooringNumbers = $row['Number']; $Assignedto['AssignedTo']; } $MooringQuery = "select * FROM mooring WHERE AssignedTo='$id'"; $MooringResult = mysql_query($MooringQuery) or die("Couldn't execute query"); while ($row1= mysql_fetch_array($MooringResult)) { $AssignedTo = $row1["AssignedTo"]; $MooringNumbers = $row1["Number"]; echo '<tr><td>' .$Surname.'</td><td>'.$Title.'</td><td>'.$MooringNumbers . '</td><td>'.$Telephone.'</td><td>' . '<a href="rlayCustomerUpdtForm.php?id='.$id.'">[EDIT]</a></td>'.'<td>'. '<a href="deleteCustomer.php?id='.$id.'">[x]</a></td>'. '</tr>'; }

  • Session variable gets updated automatically

    protected void btningAccept_Click(object sender, EventArgs e) { if(!(txtLOVCode.Text==" "||txtLOVvalue.Text==" ")) { rowid++; // DFDLOVlst.Visible=true; DataTable dt = createTemptable(); dt = (DataTable)Session["dfdtemptable"]; DataRow dr = dt.NewRow(); dr["prociLOV_Id"] = rowid; dr["prociLOV_Value"] = txtLOVvalue.Text; dr["prociLOV_Code"] = txtLOVCode.Text; Boolean isalreadyinLOVlst = false; foreach (DataRow chkrow in dt.Rows) { if (String.Equals(dr["prociLOV_Value"].ToString().Trim(), chkrow["prociLOV_Value"].ToString().Trim(),StringComparison.CurrentCultureIgnoreCase) && String.Equals(dr["prociLOV_Code"].ToString().Trim(), chkrow["prociLOV_Code"].ToString().Trim(), StringComparison.CurrentCultureIgnoreCase)) { isalreadyinLOVlst = true; break; } } if (isalreadyinLOVlst) { this.lblMessage.Text = "LOV value: " + dr["prociLOV_Value"].ToString() + ": " + dr["prociLOV_Code"].ToString() + " already exits"; } else { this.lblMessage.Text = " "; dt.Rows.Add(dr); DataTable addedLOV = createTemptable(); addedLOV = (DataTable)Session["addedLOV"]; addedLOV.ImportRow(dr); ; Session["addedLOV"] = addedLOV; } DFDLOVlst.DataSource = dt; DFDLOVlst.DataBind(); // dt.AcceptChanges(); Session["dfdtemptable"] = dt; txtLOVCode.Text = ""; txtLOVvalue.Text = ""; MDIngrdientsCode.Hide(); this.txtLOVvalue.ReadOnly = false; this.txtLOVCode.ReadOnly = false; } else this.lblMessage.Text="NO LOV VALUES ENTERED"; } Here the session varible Session["dfdtemptable"] and Session["addedLOV"] both gets updated twice and their row count becomes 2 for each session varible..But the row count sholud be 1 for each session varible.But the Session variable gets updated on the other Session varibles updation.. The Session["dfdtemptable"] gets updated when Session["addedLOV"] is assigned or updated..Can't figure out the problem..?

  • Java Detect Variable Change Using PropertyChangeSupport and PropertyChangeListener

    - by Sam
    I'm trying to print out debug statements when some third party code changes a variable. For example, consider the following: public final class MysteryClass { private int secretCounter; public synchronized int getCounter() { return secretCounter; } public synchronized void incrementCounter() { secretCounter++; } } public class MyClass { public static void main(String[] args) { MysteryClass mysteryClass = new MysteryClass(); // add code here to detect calls to incrementCounter and print a debug message } I don't have the ability to change the 3rd party MysteryClass, so I thought that I could use PropertyChangeSupport and PropertyChangeListener to detect changes to the secretCounter: public class MyClass implements PropertyChangeListener { private PropertyChangeSupport propertySupport = new PropertyChangeSupport(this); public MyClass() { propertySupport.addPropertyChangeListener(this); } public void propertyChange(PropertyChangeEvent evt) { System.out.println("property changing: " + evt.getPropertyName()); } public static void main(String[] args) { MysteryClass mysteryClass = new MysteryClass(); // do logic which involves increment and getting the value of MysteryClass } } Unfortunately, this did not work and I have no debug messages printed out. Does anyone see what is wrong with my implementation of the PropertyChangeSupport and Listener interfaces? I want to print a debug statement whenever incrementCounter is called or the value of secretCounter changes.

  • Java Variable Initialization

    - by Samuel Brainard
    Here's a piece of code I wrote. public class cube { private int length; private int breadth; private int height; private int volume; private int density; private int weight; public cube(int l,int b,int h, int d) { length=l; breadth=b; height=h; density=d; } public void volmeShow(){ volume=length*breadth*height; System.out.println("The Volume of the cube is "+this.volume); So if I implement the above cube class like this, public class cubeApp { public static void main(String[] args){ cube mycube = new cube(5,6,9,2); mycube.volumeShow(); I get an output that tells me Volume is 270. But I get an output that says Volume is 0 if I define the volume variable like this: public class cube { private int length; private int breadth; private int height; private int volume=length*breadth*height; private int density; private int weight; public cube(int l,int b,int h, int d) { length=l; breadth=b; height=h; density=d; } public void volmeShow(){ System.out.println("The Volume of the cube is "+this.volume); Can somebody please explain why this is happening? Thanks, Samuel.

    I want to change php variable ($start and $end called by var b1 and var b2) if the user clicks on button. Now I know that php is server side, but how can I do it? I read something about using $get but I don't know how to implement it: <?php if ( is_user_logged_in() ) { ?> <input type="submit" value="Start Chat" id="start_chat" style="position: absolute; top: 30px; left: 10px;" /> <?php } ?> <script> jQuery('#start_chat').click(function(){ $(this).data('clicked', true); }); var b1 = '<?php echo $start; ?>'; var b2 = '<?php echo $end; ?>'; if(jQuery('#start_chat').data('clicked')) { // change var b1 and b2 } else { // do not change anything } </script> <div id="eu_la"> <?php $start = strtotime('9:30'); $end = strtotime('12:30'); $timenow = date('U'); if((date('w') == 4) && ($timenow >= $start && $timenow <= $end)) { // day 2 = Tuesday include('facut_mine.php'); } else { do_shortcode('[upzslider usingphp=true]'); } ?>

  • Sending variable data from one of two text boxes to javascript

    - by Enyalius
    Greetings, all! I am fairly new to JS (my background is in C++, enterprise languages like assembly and COBOL, and some light .NET), so I was wondering if I could get some advice regarding how to send variable information from one of two text boxes to some javascript and then have the JS do some basic checks and such. Here's the pseudocode for what I am trying to do: <form = webForm> <p> _____________ textboxPeople| searchIcon //a text box to search an online phonebook at my company. ------------- //It has a little "magnifying glass" icon to search //(onClick), but I would also like them to be able to //search by hitting the "enter" key on their keyboards. </p> <p> _____________ texboxIntranet| searchIcon //Same as above search textbox, but this one is used if ------------- //the user wishes to search my corporate intranet site. </form> So ends the front-facing basic form that I would like to use. Now, onClick or onEnter, I would like the form to pass the contents of the text box used as well as an identifier such as "People" or "Intranet," depending on which box is used, to some basic JS on the back end: begin JavaScript: if(identifier = 'People') fire peopleSearch(); else if(identifier = 'Intranet') fire intranetSearch(); function peopleSearch() { http://phonebook.corporate.com/query=submittedValue //This will take the person //that the user submitted in the form and //place it at the end of a URL, after which //it will open said complete URL in the //same window. } function intranetSearch() { http://intranet.corporate.com/query=submittedValue //This will function in the //same way as the people search function. } end JavaScript Any thoughts/suggestions would be greatly appreciated. Thank you all in advance!

  • Shell Script Variable Quoting Problem

    - by apinstein
    I have an sh script that contains the line $PHP_COMMAND -r 'echo get_include_path();' I can not edit this script, but I need the eventual command line to be (equivalent to) php -d include_path='/path/with spaces/dir' -r 'echo get_include_path();' How can I achieve this? Below is a script that demonstrates the problem. #!/bin/sh # shell script quoting problem demonstration # I need to be able to set a shell variable with a command with # some options, like so PHP_COMMAND="php -d 'include_path=/path/with spaces/dir'" # then use PHP_COMMAND to run something in another script, like this: $PHP_COMMAND -r 'echo get_include_path();' # the above fails when executed. However, if you copy/paste the output # from this line and run it in the CLI, it works! echo "$PHP_COMMAND -r 'echo get_include_path();'" php -d include_path='/path/with spaces/dir' -r 'echo get_include_path();' # what's going on? # this is also interesting echo "\n--------------------" # this works great, but only works if include_path doesn't need quoting PHP_COMMAND="php -d include_path=/path/to/dir" echo "$PHP_COMMAND -r 'echo get_include_path();'" $PHP_COMMAND -r 'echo get_include_path();' echo "\n--------------------" # this one doesn't when run in the sh script, but again if you copy/paste # the output it does work as expected.

  • choose javascript variable based on element id from jquery

    - by phoffer
    I feel like this is a simple question, but I am still relatively new to javascript and jquery. I am developing a site for a touch interface that uses unordered lists and jquery .click functions to take input data. I have a section to input a m:ss time, with 3 divs, each containing a list of digits for time. I need to get the input for each column and set it as a variable. I originally designed the inputs to change form inputs, because I didn't understand javascript very much. It was easy to change the 3 hidden inputs by using div id's, but I can't figure out how to do it now with javascript variables. Here is my original jquery code... $("div#time>div>ul>li").click(function() { var id = $(this).parents(".time").attr("name"); var number = $(this).html(); $("input#"+id).val(number); }); The last line sets one of 3 hidden inputs equal to whatever was clicked. I need to make it so separate variables take the inputs, then I can manipulate those variables however I want. Here's a short snippet of the html, to have an idea of how jquery grabs it. <div id="time"> <h1>Time</h1> <div name="minute" class="time" id="t_minute"> M : <ul> The full time html is here: link text Thanks everyone! I've been using SO to answer many questions I've had, but I couldn't find something for this, so I figured I would join, since I'm sure I will have more questions along the way.

  • cuda 5.0 namespaces for contant memory variable usage

    - by Psypher
    In my program I want to use a structure containing constant variables and keep it on device all long as the program executes to completion. I have several header files containing the declaration of 'global' functions and their respective '.cu' files for their definitions. I kept this scheme because it helps me contain similar code in one place. e.g. all the 'device' functions required to complete 'KERNEL_1' are separated from those 'device' functions required to complete 'KERNEL_2' along with kernels definitions. I had no problems with this scheme during compilation and linking. Until I encountered constant variables. I want to use the same constant variable through all kernels and device functions but it doesn't seem to work. ########################################################################## CODE EXAMPLE ########################################################################### filename: 'common.h' -------------------------------------------------------------------------- typedef struct { double height; double weight; int age; } __CONSTANTS; __constant__ __CONSTANTS d_const; --------------------------------------------------------------------------- filename: main.cu --------------------------------------------------------------------------- #include "common.h" #include "gpukernels.h" int main(int argc, char **argv) { __CONSTANTS T; T.height = 1.79; T.weight = 73.2; T.age = 26; cudaMemcpyToSymbol(d_consts, &T, sizeof(__CONSTANTS)); test_kernel <<< 1, 16 >>>(); cudaDeviceSynchronize(); } --------------------------------------------------------------------------- filename: gpukernels.h --------------------------------------------------------------------------- __global__ void test_kernel(); --------------------------------------------------------------------------- filename: gpukernels.cu --------------------------------------------------------------------------- #include <stdio.h> #include "gpukernels.h" #include "common.h" __global__ void test_kernel() { printf("Id: %d, height: %f, weight: %f\n", threadIdx.x, d_const.height, d_const.weight); } When I execute this code, the kernel executes, displays the thread ids, but the constant values are displayed as zeros. How can I fix this?

  • Storing multiple discarded datas in a single variable using a string accumulator

    - by dan
    For an assignment for my intro to python course, we are to write a program that generates 100 sets of x,y coordinates. X must be a float between -100.0 and 100.0 inclusive, but not 0. Y is Y = ((1/x) * 3070) but if the absolute value of Y is greater than 100, both numbers must be discarded (BUT STORED) and another set generated. The results must be displayed in a table, and then after the table, the discarded results must be shown. The teacher said we should use a "string accumulator" to store the discarded data. This is what I have so far, and I'm stuck at storing the discarded data. # import random.py import random # import math.py import math # define main def main(): x = random.uniform(-100.0, 100.0) while x == 0: x = random.uniform(-100.0, 100.0) y = ((1/x) * 3070) while math.fabs(y) > 100: xDiscarded = yDiscarded = y = ((1/x) * 3070) As you can see, I run into the problem of when abs(y) 100, I'm not too sure how to store the discarded data and let it accumulate every time abs(y) 100. I'm cool with the data being stored as "351.2, 231.1, 152.2" I just don't know how to turn the variable into a string and store it. We haven't learned arrays yet so I can't do that. Any help would be much appreciated. Thanks!

  • Listing all objects that share a common variable in Javascript

    - by ntgCleaner
    I'm not exactly sure how to ask this because I am just learning OOP in Javascript, but here it goes: I am trying to be able to make a call (eventually be able to sort) for all objects with the same variable. Here's an example below: function animal(name, numLegs, option2, option3){ this.name = name; this.numLegs = numLegs; this.option2 = option2; this.option3 = option3; } var human = new animal(Human, 2, example1, example2); var horse = new animal(Horse, 4, example1, example2); var dog = new animal(Dog, 4, example1, example2); Using this example, I would like to be able to do a console.log() and show all animal NAMES that have 4 legs. (Should only show Horse and Dog, of course...) I eventually want to be able to make a drop-down list or a filtered search list with this information. I would do this with php and mySQL but I'm doing this for the sake of learning OOP in javascript. I only ask here because I don't exactly know what to ask. Thank you!

  • Assign a static function to a variable in PHP

    - by Felipe Almeida
    I would like to assign a static function to a variable so that I can send it around as a parameter. For example: class Foo{ private static function privateStaticFunction($arg1,$arg2){ //compute stuff on the args } public static function publicStaticFunction($foo,$bar){ //works $var = function(){ //do stuff }; //also works $var = function($someArg,$someArg2){ //do stuff }; //Fatal error: Undefined class constant 'privateStaticFunction' $var = self::privateStaticMethod; //same error $var = Foo::privateStaticFunction; //compiles, but errors when I try to run $var() somewhere else, as expected //Fatal error: Call to private method Foo::privateStaticMethod() from context '' $var = function(){ return Foo::privateStaticMethod(); }; } } I've tried a few more variations but none of them worked. I don't even expect this sort of functional hacking to work with PHP but hey, who knows? Is it possible to do that in PHP or will I need to come up with some hack using eval? P.S.: LawnGnome on ##php mentioned something about it being possible to do what I want using array('Foo','privateStaticMethod') but I didn't understand what he meant and I didn't press him further as he looked busy.

  • C++ : Declaring the array size with a non-constant variable

    - by Jérôme
    I always thought that when declaring an array in C++, the size has to be a constant integer value. For instance : int MyArray[5]; // correct or const int ARRAY_SIZE = 6; int MyArray[ARRAY_SIZE]; // correct but int ArraySize = 5; int MyArray[ArraySize]; // incorrect Here is also what is explained in The C++ Programming Language, by Bjarne Stroustrup : The number of elements of the array, the array bound, must be a constant expression (§C.5). If you need variable bounds, use a vector(§3.7.1, §16.3). For example: void f(int i) { int v1[i]; // error : array size not a constant expression vector<int> v2[i]; // ok } But to my big surprise, the code above does compile fine on my system ! Here is what I tried to compile : void f(int i) { int v2[i]; } int main() { int i = 3; int v1[i]; f(5); } I got no error ! I'm using GCC v4.4.0. Is there something I'm missing ?

  • Javascript Global Variable in Array

    - by user1387727
    My question may be very easy to lots of people, but I am new to Javascript. I really do not know what is wrong with the following codes. var newValue = 1; function getCurrentAmount() { return [newValue,2,3]; } var result = getCurrentAmount(); console.log(result[0] + "" + result[1] + result[2]); In the above code, the result shown in console is: undefined23 Why is the result not "123"? I am trying to use global variable because I want to increment newValue by 1 each time when the function is called. I want something like the following: var newValue = 1; function getCurrentAmount() { newValue ++; return [newValue,2,3]; } setInterval(function(){ var result = getCurrentAmount(); console.log(result[0] + "" + result[1] + result[2]); }, 1000); Also, I just tired the following codes and it works as expected. var newValue =1; function test() { newValue ++; return newValue; } console.log(test()); So I think the problem is about the Array. I hope my question is clear enough. Thanks in advance.

  • Perl need the right grep operator to match value of variable

    - by iaintunderstand
    I want to see if I have repeated items in my array, there are over 16.000 so will automate it There may be other ways but I started with this and, well, would like to finish it unless there is a straightforward command. What I am doing is shifting and pushing from one array into another and this way, check the destination array to see if it is "in array" (like there is such a command in PHP). So, I got this sub routine and it works with literals, but it doesn't with variables. It is because of the 'eq' or whatever I should need. The 'sourcefile' will contain one or more of the words of the destination array. my @destination = ('hi', 'bye'); sub in_array { my ($destination,$search_for) = @_; return grep {$search_for eq $_} @$destination; } for($i = 0; $i <=100; $i ++) { $elemento = shift @sourcefile; if(in_array(\@destination, $elemento)) { print "it is"; } else { print "it aint there"; } } Well, if instead of including the $elemento in there I put a 'hi' it does work and also I have printed the value of $elemento which is also 'hi', but when I put the variable, it does not work, and that is because of the 'eq', but I don't know what else to put. If I put == it complains that 'hi' is not a numeric value.

    basically i want to hold a parameter that retrieve value from $.post() call like this: init = function(){ var lastpage = getLastPage(); } function getLastPage(){ $.post("getInfo.php",{ last: "yes" }, function(data){ setLast(data.last); },'json'); return function setLast(data){ return data; } } so when reach at last post (last page) i should check with lastpage variable that has a value returned from getLastPage() function. I'm pretty blur with javascript pointer and all. Please help guys. update (20/4/2010): I've done the other way around, like this: init = function(){ getLastPage(); if((page+1) == $("#lastpage").val()){ alert("this is last post"); }else{ page++; //get info and display to the page here } } function getLastPage(){ $.post("getInfo.php",{ last: "yes" }, function(data){ $("#lastpage").val(data.last); },'json'); } first run the function to temporarily store the value in hidden input tag (lastpage) and then grab the value again to check it whenever i click forward button. if you all have more appropriate way please tell me.

  • Reference an object, based on a variable with it's name in it

    - by James G
    I'm looking for a way to reference an object, based on a variable with it's name in it. I know I can do this for properties and sub properties: var req = {body: {jobID: 12}}; console.log(req.body.jobID); //12 var subProperty = "jobID"; console.log(req.body[subProperty ]); //12 var property = "body"; console.log(req[property][subProperty]); //12 is it possible for the object itself? var req = {body: {jobID: 12}}; var object = "req"; var property = "body"; var subProperty = "jobID"; console.log([object][property][subProperty]); //12 or console.log(this[object][property][subProperty]); //12 Note: I'm doing this in node.js not a browser. Here is an exert from the function: if(action.render){ res.render(action.render,renderData); }else if(action.redirect){ if(action.redirect.args){ var args = action.redirect.args; res.redirect(action.redirect.path+req[args[0]][args[1]]); }else{ res.redirect(action.redirect.path); } } I could work around it by changing it to this, but I was looking for something more dynamic. if(action.render){ res.render(action.render,renderData); }else if(action.redirect){ if(action.redirect.args){ var args = action.redirect.args; if(args[0]==="req"){ res.redirect(action.redirect.path+req[args[1]][args[2]]); }else if(args[0]==="rows"){ rows.redirect(action.redirect.path+rows[args[1]][args[2]]); } }else{ res.redirect(action.redirect.path); } }

  • Expressjs route param as variable in main app

    - by MoDFoX
    For my app I have two route set up, app.get('/', routes.index); app.get('/:name', routes.index); I would like it to be so that if I don't specify a param, say just go to appurl.com (localhost:3000), it would load a default user, but if I do specify a param(localhost:3000/user), use that as the variable "username" in the following function (placed after my routes). (function getUser(){ var body = '', username = 'WillsonSM', options = { host: 'ws.audioscrobbler.com', port: 80, path: '/2.0/?method=user.gettopartists&user=' + username + '&format=json&limit=20&api_key=APIKEYGOESHERE' }; require('http').request(options, function(res) { res.setEncoding('utf8'); res.on('data', function(chunk) { body += chunk; }); res.on('end', function() { body = JSON.parse(body); artists = body.topartists.artist; }); }).end(); })(); Along with this I have my route set up like so: exports.index = function(req, res){ res.render('index', { title: 'LasTube' }); username = req.params.name; console.log(username); }; unfortunately setting username there to req.params.name does not seem to be accessible from the main app function. My question is: How can I set expressjs/nodejs to use the parameter set via /name when available, and just use a default - in this example "WillsonSM" if not available. I've tried taking "username" out of the main app, and just leaving it in the function, but username becomes undefined, as it is inaccessible from the route, and the app will not run. I can spit out "username" via the routes console.log, so assigning it there is not an issue, but as I am new to expressjs, I am unaware of how I should go about doing this. I have tried all I can think of and find from looking around the internet. Also, if there is a better way of doing this, or I am doing something wrong, please let me know. If I've left out any information, just throw in a comment and I'll try to address it.

  • jQuery variable and object caching

    - by niksy
    This is something that has been bugging me some time and every time I found myself using different solution for this. So, I have link in my document which on click creates new element with some ID. <a href="#" id="test-link">Link</a> For the purpose of easier reusing, I would like to store that new elements ID in a variable which is jQuery object var test = $('#test'); On click I append that new element on body, new element is DIV $('body').append('<div id="test"/>'); And here goes the main "problem" - if I test this new elements length with test.length it first returns 0 and later 1. But, when I test it with $('#test').length it returns 1 from the start. I suppose it is some caching mechanism and I was wondering is there better, all-around solution which will allow to store elements in variables in the start for later repurpose and in the same time work with dynamically created elements. Live, delegate, something else? What I do sometimes is create string and add it to jQuery object but I think this is just avoiding the real issue. Also, using .find() inside another jQuery object. Thanks in advance.

  • Passing list of items from Controller/Model to a variable in javascript - autocomplete

    - by newbie_developer
    I've a method in a NamesModel which fetches all the names and returns a list of names: public static List<NamesModel> GetAllNames() { List<NamesModel> names = new List<NamesModel>(); // // code to fetch records // return names; } In my controller: public ActionResult Index() { NamesModel model = new NamesModel(); model.GetAllNames(); return View(model); } In the view, I've got a textbox: @Html.TextBox("search-name") Now in my javascript, I want to fetch all names into a variable either from a model (from method) or from controller, for example: <script type="text/javascript"> $(function () { var names = ........... $(document).ready(function () { $('#search-name').autocomplete({ source: names }); }); }); </script> If I use hardcoding then it works but I want to use the names stored in the db. Is it possible? hardcoding example: var names = ["abc", "xyz"];

  • OpenGL multiple threads, variable handling [closed]

    - by toeplitz
    I have written an OpenGL program which runs in the following way: Main: - Initialize SDL - Create thread which has the OpenGL context: - Renderloop - Set camera (view) matrix with glUniform. - glDrawElements() .... etc. - Swapbuffers(); - Main SDL loop handling input events and such. - Update camera matrix of type glm::mat4. This is how I pass my camera object to the class that handles opengl. Camera *cam = new Camera(); gl.setCam(cam); where void setCam(Camera *camera) { this->camera = camera; } For rendering in the opengl context thread, this happens: glm::mat4 modelView = camera->view * model; glUniformMatrix4fv(shader->bindUniform("modelView"), 1, GL_FALSE, glm::value_ptr(modelView)); In the main program where my SDL and other things are handles I then recompute the view matrix. This his working fine without me using any mutex locks. Is this correct? On the other hand, I add objects to my scene by an "upload queue" and in this case I have to mutex lock my upload queue vector (vector class type) when adding items to it or else the program crashes. In summary: I recompute my matrix in a different thread and then use it in the opengl thread without any mutex lock. Why is this working? Edit: I think my question is similar to what was asked here: Should I lock a variable in one thread if I only need it's value in other threads, and why does it work if I don't?, only in my case it is even more simple with only one matrix being changed.
