  • Slow Response in checkbox using JQuery

    - by Dean
    Hi to all. I'm trying to optimize a website. The flow is i tried to query a certain table and all of its data entry in a page(w/ toolbars), work fine. When i tried to edit the page the problem is when i click the checkbox button i have to wait 2-5sec just by clicking it. I limit the viewing of entry to 5 only but the response on checkbox doesn't change. The tables have 100 entries in them. function checkAccess(celDiv,id) { var celValue = $(celDiv).html(); if (celValue==1) $(celDiv).html("<input type='checkbox' value='"+$(celDiv).html()+"' checked disabled>") else $(celDiv).html("<input type='checkbox' value='"+$(celDiv).html()+"' disabled>") $(celDiv).click ( function() { $('input',this).each( function(){ tr_idx = $('#detFlex1 tbody tr').index($(this).parent().parent().parent()); td_idx = $('#detFlex1 tbody tr:eq('+tr_idx+') td').index($(this).parent().parent()); td_last = 13; for(var td=td_idx+1; td<=td_last;td++) { if ($(this).attr('checked') == true) { df[0].rows[tr_idx].cell[td_idx] = 1;//index[1] = Full Access if (td_idx==3) { df[0].rows[tr_idx].cell[td] = 1; } df[0].rows[tr_idx].cell[2] = 1; if (td_idx > 3) { df[0].rows[tr_idx].cell[2] = 1; } } else { df[0].rows[tr_idx].cell[td_idx] = 0;//index[0] = With Access if (td_idx==2) { df[0].rows[tr_idx].cell[td] = 0; } else if (td_idx==3) { df[0].rows[tr_idx].cell[td] = 0; } if (td_idx > 3) { df[0].rows[tr_idx].cell[3] = 0; } } } $('#detFlex1').flexAddData(df[0]); $('.toolbar a[title=Edit Item]').trigger('click'); }); } ); } I've thought that the problem is this above code. Could anyone help me simplify this code.?

  • Using proxy models

    - by smallB
    I've created Proxy model by subclassing QAbstractProxyModel and connected it as a model to my view. I also set up source model for this proxy model. Unfortunately something is wrong because I'm not getting anything displayed on my listView (it works perfectly when I have my model supplied as a model to view but when I supply this proxy model it just doesn't work). Here are some snippets from my code: #ifndef FILES_PROXY_MODEL_H #define FILES_PROXY_MODEL_H #include <QAbstractProxyModel> #include "File_List_Model.h" class File_Proxy_Model: public QAbstractProxyModel { public: explicit File_Proxy_Model(File_List_Model* source_model) { setSourceModel(source_model); } virtual QModelIndex mapFromSource(const QModelIndex & sourceIndex) const { return index(sourceIndex.row(),sourceIndex.column()); } virtual QModelIndex mapToSource(const QModelIndex & proxyIndex) const { return index(proxyIndex.row(),proxyIndex.column()); } virtual int columnCount(const QModelIndex & parent = QModelIndex()) const { return sourceModel()->columnCount(); } virtual int rowCount(const QModelIndex & parent = QModelIndex()) const { return sourceModel()->rowCount(); } virtual QModelIndex index(int row, int column, const QModelIndex & parent = QModelIndex()) const { return createIndex(row,column); } virtual QModelIndex parent(const QModelIndex & index) const { return QModelIndex(); } }; #endif // FILES_PROXY_MODEL_H //and this is a dialog class: Line_Counter::Line_Counter(QWidget *parent) : QDialog(parent), model_(new File_List_Model(this)), proxy_model_(new File_Proxy_Model(model_)), sel_model_(new QItemSelectionModel(proxy_model_,this)) { setupUi(this); setup_mvc_(); } void Line_Counter::setup_mvc_() { listView->setModel(proxy_model_); listView->setSelectionModel(sel_model_); }

  • Conflict with @Html.LabelFor and W3C Validator?

    - by Tyler
    I have a model that I am using to present an index of a model from a database and have given a display name to some of the rows that may need spaces in them, (I.e. "weekstarting" in a db would be given a display name of "Week Starting"). So I set the display name for my model like this: [DisplayName("Week Starting")] public DateTime WeekStarting { get; set; } and then in the table headers for my table I use the following line of code to display the field name using its given display name: @Html.LabelFor(x => x.First().WeekStarting) The above all works fine. But I am using the W3C validator and it is giving me the following error for the example I have given: The for attribute of the label element must refer to a form control. Forgive me if it is obvious but what am I doing wrong here? I am not using a form I am simply displaying an index of items in a table. I have tried to look for an answer and saw someone suggest that the form controls being referred to need ids (even though I'm not using a form) but this would not be applicable in this instance because if I tried to set an id in the index it would be duplicated with each item in the index: foreach (var item in Model.Tbms) { <tr><td>@item.value</td><tr>.... would be repeated for each item, and also unsure where I would put the id in any case, the td? } Or is there a better way to label the field header, with my preferred display name in the first place? I guess I could just swap @Html.LabelFor... for Hard code field name but do I have to?

    Running this gives me a seg fault (gcc filename.c -lm), when i enter 6 (int) as a value. Please help me get my head around this.

  • only default controller is loading for all request - Critical

    Hi, My codeigniter project is in live. I have two copies of it. One in the root and another in a subfolder. Both are configered to work normal. The root copy if the one which was made after testing in a subfolder. While running from the a subfolder all worked well. But when copied to the root folder the default controller is loading for all requests. But were as in subfolders and in other servers it is working well. It is like the following A true copy in root folder like sitename.com and another true copy in a subfolder like sitename.com/abc when requesting like this sitename.com/gallery the default controller is loaded instead of gallery controller. When i tried like this sitename.com/index.php/gallery/ then it worked well... but sitename.com/gallery/ is showing only the default controller. that is the index page. here is my htaccess... php_flag magic_quotes_gpc off php_flag short_open_tag on RewriteEngine on RewriteCond $1 !^(index\.php|images|css|static|font|xml|flash|galleryimages|htc|store|robots\.txt) RewriteRule ^(.*)$ index.php/$1 [L] The server is Linux barracuda.elinuxservers.com 2.6.27.18-21 #1 SMP Tue Aug 25 18:13:37 UTC 2009 i686 PHP Version 5.2.9

  • IIS7.5 and MVC 2 : Implementing HTTP(S) security

    - by Program.X
    This is my first ASP.NET MVC application, and my first on an IIS 7.x installation whereby I have to do anything over and above the standard. I need to enforce Windows authentication on the /Index and /feeds/xxx.svc pages/services. In ASP.NET Web Forms, I would apply the Windows permissions on the files and remove Anonymous authentication in IIS 6. This needs to work over HTTP/S, but don't worry about that, that's in hand. What happens in MVC/IIS 7? I have tried modifying the permissions on the /Index.aspx view, which seems to block access. It asks me for a username/password, but does not grant access when I enter a valid username/password. Pressing Escape gives me an exception "*Access to the path 'E:\dev\xxx\xxx.ConsultantRegistration.Web.Admin\Views\ConsultantRegistration\index.aspx' is denied. *", which does get sent as a 401. So although the username/password does exist on the Index.aspx view, I can't use those credentials to access said view. I have in my web.config: What am I missing?

  • Data not transfred from form to mysql table (updating of data is not happening)

    - by Jimson
    Hi all and thanks in advance to all for this I tired and was unable to find the answer i am looking for an answer. my problem is that i am unable to update the values enterd in the form. I have attached all the files i'm using MYSQL database to fetch data. what happens is that i'm able to add and delete records from form using ajax and PHP scripts to MYSQL database, but i am not able to update data which was retrived from database. the file structure is as follows index.php is a file with ajax functions where it displays form for adding new data to MYSQL using save.php file and list of all records are view without refrishing page (calling load-list.php to view all records from index.php works fine, and save.php to save data from form) - *Delete*is an ajax function called from index.php to delete record from mysql database (function calling delete.php works fine) - Update is an ajax function called from index.php to update data using update-form.php by retriving specific record from mysql tabel, (works fine) Problem lies in updating data from update-form.php to update.php (in which update query is wrriten for mysql) i had tried in many ways at last i had figured out that data is not being transfred from update-form.php to update.php there is a small problem in jquery ajax function where it is not transfering data to update.php page. can any one correct this ????? i will be greatfull to them..... please find the link below for all files link to get my form files

  • C++ AMP, for loops to parallel_for_each loop

    - by user1430335
    I'm converting an algorithm to make use of the massive acceleration that C++ AMP provides. The stage I'm at is putting the for loops into the known parallel_for_each loop. Normally this should be a straightforward task to do but it appears more complex then I first thought. It's a nested loop which I increment using steps of 4 per iterations: for(int j = 0; j < height; j += 4, data += width * 4 * 4) { for(int i = 0; i < width; i += 4) { The trouble I'm having is the use of the index. I can't seem to find a way to properly fit this into the parallel_for_each loop. Using an index of rank 2 is the way to go but manipulating it via branching will do harm to the performance gain. I found a similar post: Controlling the index variables in C++ AMP. It also deals about index manipulation but the increment aspect doesn't cover my issue. With kind regards, Forcecast

  • c++ push_back doesn't work as it is supposed

    - by angela
    I have a class symbol_table that has a vector of objects of another class row_st.also I have an enter method where inserts objects of row_st with a passed name into the vector of desired symbol_table.but when I call the enter to enter objects with name : a;b;c;Iwill get the following result: a,b,c;b,c;c.the first element of vector gets the name of all the entered objects. and the second element also gets the name of the later entries. class row_st { public: char* name; type_u type;//int:0,flaot:1;char:2,bool:3,array: int offset; symbol_table *next; symbol_table *current; }; class symbol_table { public: vector <row_st *> row; int type; int header; int starting_stmt; int index; int i; symbol_table *previous; symbol_table(){ header=0; previous=0; index=0;i=0;starting_stmt=0;} }; and here it is the enter method: int enter(symbol_table *table,char* name,type_u type){ row_st *t=new row_st; t->name=name; t->type=type; t->offset=table->index; t->current=table; table->index++; t->next=0; table->row.push_back(t); table->header +=1; return table->row.size()-1; } the push_backed elements all points to the same address.the new call makes the same row_st every time it is called.what should I do?

  • SEO Problem for new dictionary site, google hasn't indexed content.

    - by John
    I loaded about 15,000 pages, letters A & B of a dictionary and submitted to google a text site map. I'm using google's search with advertisement as the planned mechanism to go through my site. Google's webmaster accepted the site mapps as good but then did not index. My index page has been indexed by google and at this point have not linked to any pages. So to get google's search to work I need to get all my content indexed. It appears google will not just index from the site map and so I was thinking of adding pages that spider in links from the main index page. But I don't want to create a bunch of pages that programicly link all of the pages without knowing if this has a chance to work. Eventually I plan on having about 150,000 pages each page being a word or phrase being defined. I wrote a program that is pulling this from a dictionary database. I would like to prove the content that I have to anyone interested to show the value of the dictionary in releation to the dictionary software that I'm completing. Suggestions for getting the entire site indexed by google so I can appear in the search results? Thanks

  • How to change the handler position by dragging/single click on the slider

    - by Geetha
    Hi All, I am using the following files to create a slider. Problem:Needs double click to change the handler position first click: it move the handler but the following code is not working. a second later it return back to the previous position. second click on the handler in new position, before it moves back the following code is working. Needs: I want change the media player current position with the handler current position value by dragging the handler or single click on the new position of the slider. Ex: initial position of the handler: l-------------------------------- document.mediaPlayer.currentPosition = 0 After dragging it some other position ----------------------l---------- document.mediaPlayer.currentPosition = 125 Code: var endTime = document.mediaPlayer.SelectionEnd; $("#slider-constraints").slider({ animate: true, max: endTime, range: $R(0, endTime), value: 1, enforceConstraints: false, start:function(event,index){document.mediaPlayer.currentPosition=index.value; $('#slider-constraints').slider("constraints", [0, index.value]); $('#slider-constraints').slider("value", index.value);} }); window.setInterval(function() { $('#slider-constraints').slider("value", document.mediaPlayer.currentPosition); }, 4000);

  • C++ and its type system: How to deal with data with multiple types?

    - by sub
    "Introduction" I'm relatively new to C++. I went through all the basic stuff and managed to build 2-3 simple interpreters for my programming languages. The first thing that gave and still gives me a headache: Implementing the type system of my language in C++ Think of that: Ruby, Python, PHP and Co. have a lot of built-in types which obviously are implemented in C. So what I first tried was to make it possible to give a value in my language three possible types: Int, String and Nil. I came up with this: enum ValueType { Int, String, Nil }; class Value { public: ValueType type; int intVal; string stringVal; }; Yeah, wow, I know. It was extremely slow to pass this class around as the string allocator had to be called all the time. Next time I've tried something similar to this: enum ValueType { Int, String, Nil }; extern string stringTable[255]; class Value { public: ValueType type; int index; }; I would store all strings in stringTable and write their position to index. If the type of Value was Int, I just stored the integer in index, it wouldn't make sense at all using an int index to access another int, or? Anyways, the above gave me a headache too. After some time, accessing the string from the table here, referencing it there and copying it over there grew over my head - I lost control. I had to put the interpreter draft down. Now: Okay, so C and C++ are statically typed. How do the main implementations of the languages mentioned above handle the different types in their programs (fixnums, bignums, nums, strings, arrays, resources,...)? What should I do to get maximum speed with many different available types? How do the solutions compare to my simplified versions above?

  • case insenstive string replace that correctly works with ligatures like "ß" <=> "ss"

    - by usr
    I have build a litte asp.net form that searches for something and displays the results. I want to highlight the search string within the search results. Example: Query: "p" Results: a<b>p</b>ple, banana, <b>p</b>lum The code that I have goes like this: public static string HighlightSubstring(string text, string substring) { var index = text.IndexOf(substring, StringComparison.CurrentCultureIgnoreCase); if(index == -1) return HttpUtility.HtmlEncode(text); string p0, p1, p2; text.SplitAt(index, index + substring.Length, out p0, out p1, out p2); return HttpUtility.HtmlEncode(p0) + "<b>" + HttpUtility.HtmlEncode(p1) + "</b>" + HttpUtility.HtmlEncode(p2); } I mostly works but try it for example with HighlightSubstring("ß", "ss"). This crashes because in Germany "ß" and "ss" are considered to be equal by the IndexOf method, but they have different length! Now that would be ok if there was a way to find out how long the match in "text" is. Remember that this length can be != substring.Length. So how do I find out the length of the match that IndexOf produces in the presence of ligatures and exotic language characters (ligatures in this case)?

  • CodeIgniter URI routing (dynamic, multilingual)

    - by koteko
    I'm trying to redirect all routs to one main controller. Here is my routes.php $route['default_controller'] = "main"; $route['scaffolding_trigger'] = ""; //$route['(\w{2})/(.*)'] = '$2'; //$route['(\w{2})'] = $route['default_controller']; $route['(en|ge)/(:any)'] = $route['default_controller']."/index/$1"; $route['(:any)'] = $route['default_controller']."/index/$1"; I need language id to be passed with every link (like: http://site.com/en/hello-world) Here is my main controller: class Main extends Controller { function __construct() { parent::Controller(); } function index($page_type=false, $param=false) { die($page_type.' | '.$param.'| Aaa!'); } } I want to check if predefined file type exists (like: http://site.com/en/archive/05-06-2010 - here predefined type would be archive) then do something. If not then search in the database for slug. If not found then go to 404. The problem is that I can't get index function parameters ($page_type, $param). Thanks for help.

  • codeigniter cron job with http access

    - by user1313850
    Sorry if this is a duplicate question...I've searched around and found similar advice but nothing that helps my exact problem. And please excuse the noob questions, CRON is a new thing for me. I have a codeigniter script that scrapes the html DOM of another site and stores some of that in a database. I'd like to run this script at a regular interval. This has lead me to looking into cron jobs. The page I have is at myserver.com/index.php/update I realize I can run a cron job with curl and run this page. If I want to be a bit more secure I can put a string at the end like: myserver.com/index.php/update/asdfh2784fufds And check for that in my CI controller. This seems like it would be mostly secure, but doesn't seem like the "right" way to do things. I've looked into running CI from the command line, and can execute basic pages like: php index.php mycontroller But when I try to do: php index.php update It doesn't work. I suspect this is because it needs to use HTTP to scrape the DOM of the outside page. So, my question: How do I securely run a codeigniter script with a cron job that needs HTTP access?

  • Simulating a 2-level If-Else using RewriteCond

    - by hlissner
    Hi! I'm trying to get my head around RewriteCond, and want to rewrite any requests either to a static html page (if it exists), or to a specific index.php (so long as the requested file doesn't exist). To illustrate the logic: if HTTP_HOST is '(www\.)?mydomain.com' if file exists: "/default/static/{REQUEST_URI}.html", then rewrite .* to /default/static/{REQUEST_URI}.html else if file exists: {REQUEST_FILENAME}, then do not rewrite else rewrite .* to /default/index.php I don't seem to have much trouble doing it when I don't need to test for the HTTP_HOST. Ultimately, this one .htaccess file will be handling requests for several domains. I know I could get around this with vhosts, but I'd like to figure out how to do it this way. Here's where I am at now: RewriteCond %{HTTP_HOST} ^(www\.)?mydomain\.com$ [NC] RewriteCond /default/static/%{REQUEST_URI}.html -f RewriteRule . /default/static/%{REQUEST_URI}.html [L,NC] RewriteCond %{REQUEST_FILENAME} !-f RewriteRule . /default/index.php [L,QSA] I'm not too familiar with some of the other flags, will any of them be of use here (like chain|C, next|N or skip|S)? Thanks in advance! UPDATE: I've managed to do it, but would appreciate alternatives: RewriteEngine On RewriteRule ^(.+)/$ /$1 [L] RewriteCond %{HTTP_HOST} ^(domainA|domainB)\.com [NC] RewriteCond %{DOCUMENT_ROOT}/%1/static/%{REQUEST_URI}.html -f RewriteRule (.*)? /%1/static/$1.html [NC,L] RewriteCond %{HTTP_HOST} ^(domainA|domainB)\.com [NC] RewriteCond %{REQUEST_FILENAME} !-f RewriteRule .* /%1/index.php [L,QSA]

  • Adding property:value pairs from GooglemapsAPI to an existing json/javascript object

    - by Rockinelle
    I am trying to create a script that finds the closest store/location to a customer using googlemapsAPI. So I've got a json object which is a collection of store objects. Using Jquery's .each to iterate through that object, I am grabbing the driving time from the customer to each store. If it finds the directions, It copies the duration of the drive which is an object with the time in seconds and a human readable value. That appears to work, however when I try to sort through all of those store objects with the drivetime added, I cannot read the object copied from google. If I console.log the whole object, 'closest_store', It shows the values I'm looking for. When I try to read the values directly via closest_store.driveTime, Firebug is outputting undefined in the console. What am I missing here? $.getJSON('<?php echo Url::base() ?>oldservices/get_locations', {}, function(data){ $.each(data, function(index, value) { var end = data[index].address; var request = { origin: start, destination: end, travelMode: google.maps.DirectionsTravelMode.DRIVING }; directionsService.route(request, function(response, status) { //console.log(response); if (status == google.maps.DirectionsStatus.OK) { value.driveTime = response.trips[0].routes[0].duration.value; //console.log(response.trips[0].routes[0].duration.value); }; }); }); var closest_store; $.each(data, function(index, current_store) { if (index == 0) { closest_store = current_store; } else if (current_store.driveTime.value < closest_store.driveTime.value) { closest_store = value }; console.log(current_store.driveTime); } ) });

  • Help on MySQL table indexing when GROUP BY is used in a query

    - by Silver Light
    Thank you for your attention. There are two INNODB tables: Table authors id INT nickname VARCHAR(50) status ENUM('active', 'blocked') about TEXT Table books author_id INT title VARCHAR(150) I'm running a query against these tables, to get each author and a count of books he has: SELECT a. * , COUNT( b.id ) AS book_count FROM authors AS a, books AS b WHERE a.status != 'blocked' AND b.author_id = a.id GROUP BY a.id ORDER BY a.nickname This query is very slow (takes about 6 seconds to execute). I have an index on books.author_id and it works perfectly, but I do not know how to create an index on authors table, so that this query could use it. Here is how current EXPLAIN looks: id select_type table type possible_keys key key_len ref rows Extra 1 SIMPLE a ALL PRIMARY,id_status_nickname NULL NULL NULL 3305 Using where; Using temporary; Using filesort 1 SIMPLE b ref key_author_id key_author_id 5 a.id 2 Using where; Using index I've looked at MySQL manual on optimizing queries with group by, but could not figure out how I can apply it on my query. I'll appreciate any help and hints on this - what must be the index structure, so that MySQL could use it?

  • Explaining a Ruby code snippet

    - by Michael Foukarakis
    I'm in that uncomfortable position again, where somebody has left me with a code snippet in a language I don't know and I have to maintain it. While I haven't introduced Ruby to myself some parts of it are quite simple, but I'd like to hear your explanations nonetheless. Here goes: words = File.open("lengths.txt") {|f| f.read }.split # read all lines of a file in 'words'? values = Array.new(0) words.each { |value| values << value.to_i } # looked this one up, it's supposed to convert to an array of integers, right? values.sort! values.uniq! diffs = Array.new(0) # this looks unused, unless I'm missing something obvious sum = 0 s = 0 # another unused variable # this looks like it's computing the sum of differences between successive # elements, but that sum also remains unused, or does it? values.each_index { |index| if index.to_i < values.length-1 then sum += values.at(index.to_i + 1) - values.at(index.to_i) end } # could you also explain the syntax here? puts "delta has the value of\n" # this will eventually print the minimum of the original values divided by 2 puts values.at(0) / 2 The above script was supposed to figure out the average of the differences between every two successive elements (integers, essentially) in a list. Am I right in saying this is nowhere near what it actually does, or am I missing something fundamental, which is likely considering I have no Ruby knowledge?

I am new to C++ so I am attempting to code this out but am running into a problem. The main problem is how do I instantiate a class with a variable if I don't know how many I will have to do ahead of time. The user could ask to add 1 book or 1000. I am looking at this basic code: This is the simple code I started with. I wanted to have an index int keep a number and have the book class I create be called by that int (0, 1, 2, etc...) So I attempted to convert the incoming index int into a string, but I'm kind of stuck from here. void addBook(int index){ string bookName; std::stringstream ss; ss << index; book bookName; cout << "Enter the Books Title: "; cin >> bookName.title; } But obviously this doesn't work as "bookName" is a string to the computer and not the class member I tried to create. All of the tutorials I have seen online and in my text show the classes being instantiated with names in the code, but I just don't know how to make it variable so I can create any amount of "books" that the user might want. Any insight on this would be appreciated. Thank you for your time.

  • How can I use SQL Server's full text search across multiple rows at once?

    - by Morbo
    I'm trying to improve the search functionality on my web forums. I've got a table of posts, and each post has (among other less interesting things): PostID, a unique ID for the individual post. ThreadID, an ID of the thread the post belongs to. There can be any number of posts per thread. Text, because a forum would be really boring without it. I want to write an efficient query that will search the threads in the forum for a series of words, and it should return a hit for any ThreadID for which there are posts that include all of the search words. For example, let's say that thread 9 has post 1001 with the word "cat" in it, and also post 1027 with the word "hat" in it. I want a search for cat hat to return a hit for thread 9. This seems like a straightforward requirement, but I don't know of an efficient way to do it. Using the regular FREETEXT and CONTAINS capabilities for N'cat AND hat' won't return any hits in the above example because the words exist in different posts, even though those posts are in the same thread. (As far as I can tell, when using CREATE FULLTEXT INDEX I have to give it my index on the primary key PostID, and can't tell it to index all posts with the same ThreadID together.) The solution that I currently have in place works, but sucks: maintain a separate table that contains the entire concatenated post text of every thread, and make a full text index on THAT. I'm looking for a solution that doesn't require me to keep a duplicate copy of the entire text of every thread in my forums. Any ideas? Am I missing something obvious?

  • CodeIgniter subfolders and URI routing

    - by shummel7845
    I’ve read the manual on URI routing and views and something is not clicking with me. In my views folder, I have a subfolder called products. In there is a file called product_view. In my controller, I have: function index() { $data['title'] = 'Product Overview'; $data['main_content'] = 'products/product_view'; $this->load->view('templates/main.php', $data); } The template loads a header view, a footer view and a navigation view, plus the view as a main content variable. In my URI routing, I have: $route['products/product-overview'] = 'products/product_view']; This causes a 404 error when I try to go to domain.com/products/product-overview. Do I need to do something with my .htaccess? If so, what? Here is my .htaccess: Options +FollowSymLinks Options -Indexes DirectoryIndex index.php RewriteEngine on RewriteCond $1 !^(index\.php|resources|images|css|js|robots\.txt|favicon\.ico) RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ index.php?/$1 [L,QSA] I’d appreciate some specific help, as the documentation isn’t specific on how to address this. I’ve done a little searching in the forums, and didn’t see anything, but I’m posting this while I keep looking.

  • how to fetch data using jquery

    - by user3566029
    I have tried to connect my index.php file in 000webhost.com using jQuery. From the site menu I have connected with 000webhost using FTP details available in 000webhost.com. When I tried to read data from jQuery it doesn’t working. Anyone please tell me what should I need to change? Should I need to connect my Dreamweaver database to webhost? If yes please explain? This is what I have done. index.php $mysql_host = "mysql0.000webhost.com"; $mysql_database = "a000000_mydb"; $mysql_user = "a000000_root"; $mysql_password = "******"; $conn=@mysql_connect ( $mysql_host,$mysql_user,$mysql_password )or die('aa'); mysql_select_db($mysql_database,$conn) or die('eoor on db'); $quer=mysql_query("SELECT * FROM sam"); $res=array(); while($row=mysql_fetch_row($quer)) { $res[]=$row; } print(json_encode($res)); return json_encode($res); mysql_close(); index.html $.get('public_html/index.php', function( data ) { alert( 'Successful' +data); });
