  • Is there a way to exit a Greasemonkey script?

    - by SimpleCoder
    I know that you can use return; to return from a Greasemonkey script, but only if you aren't in another function. For example, this won't work: // Begin greasemonkey script function a(){ return; // Only returns from the function, not the script } // End greasemonkey script Is there a built in Greasemonkey function that would allow me to halt execution of the script, from anywhere in the script? Thank you,

  • managing html rich text selections

    - by swami
    Hi, I am writing a component for a web app which will display some html, and let me capture and manipulate the selection boundaries (of the text selected by the user). I have done this successfully (for Mozilla) with a simple div element using window.getSelection(). However, the browser selection API is different for IE. If I were to use a textarea instead (for interacting with the selection api), is there a uniform API across the browsers? Then I would need to overlay a DIV on top of this to display the styled text, and presumably I'd need to manage the cursor etc... Basically I want a rich text editor - but without editing. Does anyone have any advice on the best way to go about this, which is quick, simple and cross browser compatible. I don't want to spend ages reinventing the wheel... (If anyone's interested - this is for an online xml editor. I capture the users selection on a html version of the xml doc and then send the selection offsets info to the server, where the real xml doc gets marked up). Kind Regards Swami

  • Caller property of JS for "foo = function()" style of coding

    - by arvind
    I want to use the property of "caller" for a function which is defined here It works fine for this style of function declaration function g() { alert(g.caller.name) // f } function f() { alert(f.caller.name) // undefined g() } f() JSfiddle for this But then my function declaration is something like g = function() { alert(g.caller.name) // expected f, getting undefined } f = function() { alert("calling f") alert(f.caller.name) // undefined g() } f() and I am getting undefined (basically not getting anything) JSfiddle for this Is there any way that I can use the caller property without having to rewrite my code? Also, I hope I have not made any mistakes in usage and function declaration since I am quite new to using JS.

  • Word wrap in multiline textbox after 35 characters

    - by Kanavi
    <asp:TextBox CssClass="txt" ID="TextBox1" runat="server" onkeyup="CountChars(this);" Rows="20" Columns="35" TextMode="MultiLine" Wrap="true"> </asp:TextBox> I need to implement word-wrapping in a multi-line textbox. I cannot allow users to write more then 35 chars a line. I am using the following code, which breaks at precisely the specified character on every line, cutting words in half. Can we fix this so that if there's not enough space left for a word on the current line, we move the whole word to the next line? function CountChars(ID) { var IntermediateText = ''; var FinalText = ''; var SubText = ''; var text = document.getElementById(ID.id).value; var lines = text.split("\n"); for (var i = 0; i < lines.length; i++) { IntermediateText = lines[i]; if (IntermediateText.length <= 50) { if (lines.length - 1 == i) FinalText += IntermediateText; else FinalText += IntermediateText + "\n"; } else { while (IntermediateText.length > 50) { SubText = IntermediateText.substring(0, 50); FinalText += SubText + "\n"; IntermediateText = IntermediateText.replace(SubText, ''); } if (IntermediateText != '') { if (lines.length - 1 == i) FinalText += IntermediateText; else FinalText += IntermediateText + "\n"; } } } document.getElementById(ID.id).value = FinalText; $('#' + ID.id).scrollTop($('#' + ID.id)[0].scrollHeight); } Edit - 1 I have to show total max 35 characters in line without specific word break and need to keep margin of two characters from the right. Again, the restriction should be for 35 characters but need space for total 37 (Just for the Visibility issue.)

  • how to use a parameterized function for the Default Binding of a Sql Server column

    - by Walt Gaber
    I have a table that catalogs selected files from multiple sources. I want to record whether a file is a duplicate of a previously cataloged file at the time the new file is cataloged. I have a column in my table (“primary_duplicate”) to record each entry as ‘P’ (primary) or ‘D’ (duplicate). I would like to provide a Default Binding for this column that would check for other occurrences of this file (i.e. name, length, timestamp) at the time the new file is being recorded. I have created a function that performs this check (see “GetPrimaryDuplicate” below). But I don’t know how to bind this function which requires three parameters to the table’s “primary_duplicate” column as its Default Binding. I would like to avoid using a trigger. I currently have a stored procedure used to insert new records that performs this check. But I would like to ensure that the flag is set correctly if an insert is performed outside of this stored procedure. How can I call this function with values from the row that is being inserted? USE [MyDatabase] GO SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO CREATE TABLE [dbo].[FileCatalog]( [id] [uniqueidentifier] NOT NULL, [catalog_timestamp] [datetime] NOT NULL, [primary_duplicate] nchar NOT NULL, [name] nvarchar NULL, [length] [bigint] NULL, [timestamp] [datetime] NULL ) ON [PRIMARY] GO ALTER TABLE [dbo].[FileCatalog] ADD CONSTRAINT [DF_FileCatalog_id] DEFAULT (newid()) FOR [id] GO ALTER TABLE [dbo].[FileCatalog] ADD CONSTRAINT [DF_FileCatalog_catalog_timestamp] DEFAULT (getdate()) FOR [catalog_timestamp] GO ALTER TABLE [dbo].[FileCatalog] ADD CONSTRAINT [DF_FileCatalog_primary_duplicate] DEFAULT (N'GetPrimaryDuplicate(name, length, timestamp)') FOR [primary_duplicate] GO USE [MyDatabase] GO SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO CREATE FUNCTION [dbo].[GetPrimaryDuplicate] ( @name nvarchar(255), @length bigint, @timestamp datetime ) RETURNS nchar(1) AS BEGIN DECLARE @c int SELECT @c = COUNT(*) FROM FileCatalog WHERE name=@name and length=@length and timestamp=@timestamp and primary_duplicate = 'P' IF @c > 0 RETURN 'D' -- Duplicate RETURN 'P' -- Primary END GO

  • jQuery: Moving window (or FIFO) type DIV?

    - by Legend
    I have been trying to get this effect for a couple of hours now and I must admit I am failing at it. I am trying to construct a DIV that accepts a particular number of items (say 5), when the 6th item is added, the first item that was aded should be removed (first-in-first-out). The feel should have some kind of a fadeIn and fadeOut. Here's what I managed to write till now: ... //Create a ul element with id 'ulele' and add it to a div ... //Do an ajax call and when an element arrives Hash = ComputeHash(message) if(!$("#" + Hash).exists()) { var element = $("<li></li>").html(message).attr('id', Hash).prependTo("#ulele"); $("#" + Hash).hide().delay(10000 - 1000 * messageNumber).show("slow"); _this.prune("#ulele"); } ... prune: function(divid) { $("#" + divid).children().each( function(i, elemLi) { if(i >= maxMessages) $(this).delay(10000).hide("slow").delay(10000).remove(); } ); } I've tried a couple of variations but the final effect I am getting is not that of a FIFO. The elements disappear instantaneously despite the delay and hide("slow") calls. Anyone has a more straightforward approach?

  • JQuery Modal Boxes and Iframe

    - by Ólafur Waage
    I've been using Simple Modal and i feel it doesn't live up to what i need at the moment. Is there a Modal Box that supports loading external files and allows those external files to close the modal box and redirect the parent page to some url. An example of what i want to do. You have a list of users, you could click "Add user" and a Modal Box with the form pops up, you fill that in and submit it. That would close the box and reload the user list page so you would see the user in the list. Then you could click "Edit user" and a Modal Box with the user info filled in the form fields would pop up and you could edit, submit and it would close and refresh. I know this can be done if i have the user info form as a hidden div for each user but this will not scale well and it is a lot of overhead data. I found some code about this on Google Code but just can't get it to work (possibly different simple modal version I am willing to change to another modal box tool also. UPDATE: Do either Thickbox or Fancybox support being closed from a child IFrame element?

  • How to use Spanish characters in Handlebars templates

    - by Jon Rose
    I am wondering what the idiomatic way to render special language characters is using Handlebars.js templates. When I render the normal html I can use something like the Spanish lowercase e, &#233, and it renders as expected. When I pass the same text as a string to my Handlebars template I just see the characters &#233. I have tried creating a Handlebars helper that used jquery to render the text using .html() then returning the .html() of the tmp element and I get the same results.

  • jQuery Address double load on init

    - by dazhall
    Hi All! I'm using jQuery Address to load in my content, but it's doing it twice on the init. I set it up so that if you go to the main category it loads the first image, but it's doing it twice and I'm not sure how to stop it. A fresh pair of eyes would be appreciated! $.address.init(function(event) { $('#carousel-clip a').address(); if(!event.pathNames[0]) { var url = $('#carousel-clip ul li:first a').attr('href').replace('#!/',''); $.address.path(url); } }).change(function(event) { if(event.pathNames[0]) { $.getJSON(location.pathname + 'image/' + event.pathNames[0] + '/', function(data, textStatus, XMLHttpRequest) { handler(data); }); } }); You can see it working here: http://bit.ly/cKftwA Thanks!

  • Html combo box to database record Id

    - by LanguaFlash
    I'm fairly sure there has to be a simple solution to my problem, but I am a new web developer and can't quite figure it out. On my page I have a combo box whose values are filled from my database. When the user submits the form, how to I go about converting those values back to the record numbers in the database? Up to now I have been just doing a sort of reversed lookup in my database to try to get the record's ID. This has quite a few obvious flaws and I am sure that there has to be a better way. I am used to MS Forms combo boxes where the record data and ID are never separated. But in the case of a web form, I have no way to do multiple columns in the combo box like I am used to. Thanks!

  • Are there known problems with >= and <= and the eval function in JS?

    - by Augier
    I am currently writing a JS rules engine which at one point needs to evaluate boolean expressions using the eval() function. Firstly I construct an equation as such: var equation = "relation.relatedTrigger.previousValue" + " " + relation.operator + " " + "relation.value"; relation.relatedTrigger.previousValue is the value I want to compare. relation.operator is the operator (either "==", "!=", <=, "<", "", ="). relation.value is the value I want to compare with. I then simply pass this string to the eval function and it returns true or false as such: return eval(equation); This works absolutely fine (with words and numbers) or all of the operators except for = and <=. E.g. When evaluating the equation: relation.relatedTrigger.previousValue <= 100 It returns true when previousValue = 0,1,10,100 & all negative numbers but false for everything in between. I would greatly appreciate the help of anyone to either answer my question or to help me find an alternative solution. Regards, Augier. P.S. I don't need a speech on the insecurities of the eval() function. Any value given to relation.relatedTrigger.previousValue is predefined. edit: Here is the full function: function evaluateRelation(relation) { console.log("Evaluating relation") var currentValue; //if multiple values if(relation.value.indexOf(";") != -1) { var values = relation.value.split(";"); for (x in values) { var equation = "relation.relatedTrigger.previousValue" + " " + relation.operator + " " + "values[x]"; currentValue = eval(equation); if (currentValue) return true; } return false; } //if single value else { //Evaluate the relation and get boolean var equation = "relation.relatedTrigger.previousValue" + " " + relation.operator + " " + "relation.value"; console.log("relation.relatedTrigger.previousValue " + relation.relatedTrigger.previousValue); console.log(equation); return eval(equation); } } Answer: Provided by KennyTM below. A string comparison doesn't work. Converting to a numerical was needed.

  • using multi-markers with multi info-windows

    - by mohsen
    I have an array of info-windows corresponding to an array of markers. Now, I have a problem, I use the below code to generate an info-window, when clicking on the marker all the markers disappear unless one, also when I click on that marker there is no info-window come out. What is the wrong with my code ? or what shall I do ? Any answer will be very appreciated, Thanks in advance. This code is inside a for loop: infoWindoArray[i][j] = new google.maps.InfoWindow({ content:"Lat: "+this.position.lat() + "\nLng: " + this.position.lng() + "\n"+ this.customInfo, }); google.maps.event.addListener(AllMarkers[i][j], 'click', (function(x) { return function() {infoWindoArray[i][j].open(map,AllMarkers[i][j]);} })(x));

  • jquery: Writing a method

    - by Mark
    This is the same question as this: http://stackoverflow.com/questions/2890620/jquery-running-a-function-in-a-context-and-adding-to-a-variable But that question was poorly posed. Trying again, I'm trying to do something like this: I have a bunch of elements I want to grab data from, the data is in the form of classes of the element children. <div id='container'> <span class='a'></span> <span class='b'></span> <span class='c'></span> </div> <div id='container2'> <span class='1'></span> <span class='2'></span> <span class='3'></span> </div> I have a method like this: jQuery.fn.grabData = function(expr) { return this.each(function() { var self = $(this); self.find("span").each(function (){ var info = $(this).attr('class'); collection += info; }); }); }; I to run the method like this: var collection = ''; $('#container').grabData(); $('#container2').grabData(); The collection should be adding to each other so that in the end I get this console.log(collection); : abc123 But collection is undefined in the method. How can I let the method know which collection it should be adding to? Thanks.

  • POST parameters strangely parsed inside phantomjs

    - by user61629
    I am working with PHP/CURL and would like to send POST data to my phantomjs script, by setting the postfields array below: In my php controller I have: $data=array('first' => 'John', 'last' => 'Smith'); $url='http://localhost:7788/'; $output = $this->my_model->get_data($url,$data); In my php model I have: public function get_data($url,$postFieldArray) { $ch = curl_init(); curl_setopt($ch, CURLOPT_COOKIEJAR, $cookieFile); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE); curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0)"); curl_setopt($ch, CURLOPT_POST, TRUE); curl_setopt($ch, CURLOPT_POSTFIELDS, $postFieldArray); curl_setopt($ch, CURLOPT_URL, $url); $output = curl_exec($ch); In my phantomJS script that I am running locally I have: // import the webserver module, and create a server var server = require('webserver').create(); var port = require('system').env.PORT || 7788; console.log("Start Application"); console.log("Listen port " + port); // Create serever and listen port server.listen(port, function(request, response) { // Print some information Just for debbug console.log("We got some requset !!!"); console.log("request method: ", request.method); // request.method POST or GET if(request.method == 'POST' ){ console.log("POST params should be next: "); console.log("POST params: ",request.post); exit; } I first start and run the phantomjs script (myscript.js) from the command line, then I run my php script. The output is: $ phantomjs.exe myscript.js Start Application Listen port 7788 null We got some requset !!! request method: POST POST params should be next: POST params: ------------------------------e70d439800f9 Content-Disposition: form-data; name="first" John ------------------------------e70d439800f9 Content-Disposition: form-data; name="last" Smith ------------------------------e70d439800f9-- I'm confused about the the output. I was expecting something more like: first' => 'John', 'last' => 'Smith Can someone explain why it looks this way? How can I parse the request.post object to assign to variables inside myscript.js

  • Proper Regex to find and replace escaped UTF-8 strings

    - by Piet Binnenbocht
    (edited) I am reading a JSON file that includes some UTF-8 characters that are encoded like this: "\uf36b". I am trying to write a RegExp to convert this to an HTML entity that looks like "&#x1F36B;". This displays the character correctly in my html page. I haven't been able to correctly display the character that should be associated with "\uf36b", especially when in a longer sentence that also includes other text. How can I write a regexp that replaces strings like "\uf4d6" and "\uf36b" but leaves other text alone? Example: var str = "I need \uf36b #chocolate"; This should be converted to: I need &#x1F36B; #chocolate;

  • Website: Make printable version with footnotes?

    - by DavidR
    I have a website that uses editable divs so that a user can modify or make notes to a text. Is there a way I can have the website generate a pdf or some printable document with footnotes, such that if a user has this: <div class="text" id="text_1"> <div class="bodyTest">This is the body text</div> <div class="notes">These are the notes</div> </div> <div class="text" id="text_2"> <div class="bodyTest">This is the body text</div> <div class="notes">These are the notes</div> </div> the website will generate a printable version (or document) in such a way thatdiv.notes will appear as a footnote on the same page on which div#text_1 appears? I don't need a full answer, just a shove in the general direction will be amazing. Thanks.

  • d3: Coloring Multiple Lines from Nested Data

    - by diet_coke
    I'm currently assembling some line graphs with circles at the datapoints from arrays of JSON objects formatted like so: var data = [{ "name": "metric1", "datapoints": [ [10.0, 1333519140], [48.0, 1333519200] ] }, { "name": "metric2", "datapoints": [ [48.0, 1333519200], [12.0, 1333519260] ] }] I want to have a color for each metric, so I'm trying to color them based on the index of the object within the array data. The code I have currently for just placing the circles looks like: // We bind an svg group to each metric. var metric_groups = this.vis.selectAll("g.metric_group") .data(data).enter() .append("g") .attr("class", "metric_group"); // Then bind a circle for each datapoint. var circles = metric_groups.selectAll("circle") .data(function(d) { return d.datapoints; }); circles.enter().append("circle") .attr("r", 3.5); Now if I change that last bit to something like: circles.enter().append("circle") .attr("r", 3.5); .style("fill", function(d,i) { return i%2 ? "red" : "blue"; } I get alternating red and blue circles, as could be expected. Taking some advice from Nested Selections : 'Nesting and Index', I tried: circles.enter().append("circle") .attr("r", 3.5); .style("fill", function(d,i,j) { return j%2 ? "red" : "blue"; } Which doesn't work (j is undefined), presumably because we are in the named property datapoints, rather than an array element. How might I go about doing the coloring that I want without changing my data structure? Thanks!

  • How do I flatten an associative array into an array with only values in PHP?

    - by aalaap
    I have an array that has keys and values. For eg: Array ( [name] => aalaap [age] => 29 [location] => mumbai ) I want to convert the keys from this into values, but I want the values to apear right after the keys. For eg: Array ( [0] => name [1] => aalaap [2] => age [3] => 29 [4] => location [5] => mumbai ) I can easily write an iteration function that will do this... for eg: array_flatten($arr) { foreach ($arr as $arrkey => $arrval) { $arr_new[] = $arrkey; $arr_new[] = $arrval; } return $arr_new; } ...but I'm trying to find out if there's any way this can be accomplished using array_combine, array_keys, array_values and/or array_merge, preferably in one, so i don't need to use a custom function. Is there?

Is this the best way to do this, or is there some kind of nifty jQuery method that you prefer?

  • jQuery rotator not rotating properly - too much recursion

    - by Matt Nathanson
    I've built a custom jQuery rotator using just basic animation to rotate the 3 Divs (images). I've built the function and then reinitiate the function using it as a call back. Here's the code: function ImageRotate() { var CurrentFeature = "#container" + featureNumber; $(CurrentFeature).stop(false, true).delay(4500).animate({'top' : '330px'}, 3000); var featureNumber2 = featureNumber-1; if ( featureNumber == 1) {featureNumber2=3} var CurrentFeature2 = "#container" + featureNumber2; $(CurrentFeature2).stop(false, true).delay(4500).animate({'top' : '0px'}, 3000); $('#container2').stop(false, true).delay(4500).animate({'top' : '-330px'}, 25); var featureNumber3 = featureNumber+1; if ( featureNumber == 3){featureNumber3=1} var CurrentFeature3 = "#container" + featureNumber3; $(CurrentFeature3).stop(false, true).delay(7500).animate({'top' : '0px'}, 3000); $(CurrentFeature2).stop(false, true).delay(4500).animate({'top' : '330px'}, 3000); $(CurrentFeature).stop(false, true).delay(4500).animate({'top' : '-330px'}, 25); if (featureNumber ==1) {featureNumber=3} else{featureNumber--}; $(CurrentFeature).stop(false, true).delay(7500).animate({'top' : '0px'}, 3000); $(CurrentFeature3).stop(false, true).delay(4500).animate({'top' : '330px'}, 3000); $(CurrentFeature2).stop(false, false).delay(4500).animate({'top' : '-330px'}, 25,ImageRotate()); }; It's worth noting that when calling the function again I also tried making another function called ImageRotate2(); and it did the same thing. It loops, but i get all sorts of funkiness. Edit: I've also tried some answers in the replies and they both leave me with recursion errors each second.

  • I have a bunch of images being shown on click via JQuery - any easy way to animate this?

    - by Cenk
    This is the (quite simple) JS code I'm using: $(document).ready(function() { $(".button-list .next").click(function() { project = $(this).parents().filter(".projektweb").eq(0); currentimg = project.find(".images-list li.current"); nextimg = currentimg.next(); firstimg = project.find(".images-list li:first"); currentimg.removeClass("current"); if (nextimg.is("li")) nextimg.addClass("current"); else firstimg.addClass("current"); return false; }); $(".button-list .prev").click(function() { project = $(this).parents().filter(".projektweb").eq(0); currentimg = project.find(".images-list li.current"); previmg = currentimg.prev(); lastimg = project.find(".images-list li:last"); currentimg.removeClass("current"); if (previmg.is("li")) previmg.addClass("current"); else lastimg.addClass("current"); return false; }); }); And this is how the HTML code for the image list looks like: <ul class="images-list"> <li class="current"><img src="img/1.jpg" alt="" /></li> <li><img src="img/1b.jpg" alt="" /></li> </ul> <ul class="button-list"> <li><a class="button prev" href="#">?</a></li> <li><a class="button next" href="#">?</a></li></ul> The CSS: .images-list { height: 460px; list-style-type:none; float:left; width: 460px; overflow:hidden; position:relative; } .images-list img { height: 460px; width: 460px; display:block; } .images-list li { display:none; } .images-list li.current { display:block; } What I'd like to do is animate the images as they come and go - right now they just appear, which is OK but a bit more eye-candy would be nice. Can anyone help me out here? It it even possible to do it this way? Thanks!!
