  • Can I use "map" as a substitute for "for each"/"for in"?

    - by John Mee
    For a little while now javascript has the "map" function to loop over arrays. It appears possible to use it as a 'foreach' operator for example: var arr = ['a','b','c'] var doubles = arr.map(function(val){ return val + val }) Is this better or worse than saying for(var i in arr){ ... 50/50: saves having to use the index but adds a callback; it doesn't seem very common so I hesitate to use it but still want to.

    - by pakore
    I was trying to implement an image panner I found here Chrome renders the same document differently depending on the extension of the file requested. I have created a test case, where it works when the file it's not named as test.xhtml You can download the test case from here Does anybody know why or how to solve it? I want my files to be .xhtml In IE and FF it works fine. Code: test.html / test.xhtml (change the name to see that works with one but not with the other). <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en"> <head> <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"/> <style type="text/css"> /*Default CSS for pan containers*/ .pancontainer { position: relative; /*keep this intact*/ overflow: hidden; /*keep this intact*/ width: 300px; height: 300px; border: 1px solid black; } </style> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> <script type="text/javascript" src="http://www.dynamicdrive.com/dynamicindex4/imagepanner.js"></script> </head> <body> <div class="pancontainer" data-orient="center" data-canzoom="yes" style="width: 350px; height: 200px; float: left; position: relative; overflow-x: hidden; overflow-y: hidden; cursor: move; "><img src="./test_files/image.jpg" style="position: absolute; width: 700px; height: 525px; left: -175px; top: -163px; display: block;" /> </div> </body> </html>

  • Is there a way to get a mobile Safari WebApp to "forget" its state?

    - by Alex Mcp
    I have a nascent bridge scoring app that is meant to be stored locally on an iPod touch/iPhone (iPad? Would probably be fugly...) So far so good, got a custom icon rolling and basic JS navigation laid out, but my problem is that it retains its state when I quit the app. Is there a simple magic Apple meta tag for this? Or is it achieved with javascript? Thanks for any insight.

  • Define "cyclic data structures"

    At the JSON site it says JSON does not support cyclic data structures, so be careful to not give cyclical structures to the JSON stringifier. What does it mean by this? Can someone give me an example of such a data structure in Javascript?

  • How to determine if the user clicked OK or CANCEL when exiting Silverlight?

    - by eflles
    Based on http://mark.mymonster.nl/2009/02/28/integration-of-browsers-unloading-with-silverlight/ I know when the user closes a browser window containing Silverlight, by use of javascript. This basically creates a popup window, where the user can stay on the page(by clicking CANCEL), or exit the page (by clicking OK). I am interested in how I can determine if the user wants to exit the page, or continue to stay on the page.

  • JSLint reports unexpected use of '&' and '|' -- I'd like to clean this

    - by Zhami
    I'm trying to get my Javascript code 100% JSLint clean. I've got some JS code that I've lifted from elsewhere to create a UUID. That code has the following line: s[16] = hexDigits.substr((s[16] & 0x3) | 0x8, 1); This line incites JSLint to generate two error messages: 1) Unexpected use of '&' 2) Unexpected use of '|' I don't understand why -- I'd appreciate counsel regarding how to recode to eliminate the error message.

  • JQuery Ajax Updating MySQL Database, But Not Running Success Function

    - by myrmidon16
    I am currently using the JQuery ajax function to call an exterior PHP file, in which I select and add data in a database. Once this is done, I run a success function in JavaScript. What's weird is that the database is updating successfully when ajax is called, however the success function is not running. Here is my code: <!DOCTYPE html> <head> <script type="text/javascript" src="jquery-1.6.4.js"></script> </head> <body> <div onclick="addtask();" style="width:400px; height:200px; background:#000000;"></div> <script> function addtask() { var tid = (Math.floor(Math.random() * 3)) + 1; var tsk = (Math.floor(Math.random() * 10)) + 1; if(tsk !== 1) { $.ajax({ type: "POST", url: "taskcheck.php", dataType: "json", data: {taskid:tid}, success: function(task) {alert(task.name);} }); } } </script> </body> </html> And the PHP file: session_start(); $connect = mysql_connect('x', 'x', 'x') or die('Not Connecting'); mysql_select_db('x') or die ('No Database Selected'); $task = $_REQUEST['taskid']; $uid = $_SESSION['user_id']; $q = "SELECT task_id, taskname FROM tasks WHERE task_id=" .$task. " LIMIT 1"; $gettask = mysql_fetch_assoc(mysql_query($q)); $q = "INSERT INTO user_tasks (ut_id, user_id, task_id, taskstatus, taskactive) VALUES (null, " .$uid. ", '{$gettask['task_id']}', 0, 1)"; $puttask = mysql_fetch_assoc(mysql_query($q)); $json = array( "name" => $gettask['taskname'] ); $output = json_encode($json); echo $output; Let me know if you have any questions or comments, thanks.

  • jquery element not defined, but it used to skip it...

    - by pfunc
    I recently transferred a site to a new host. Reloaded everything, and the javascript that worked fine before is breaking at an element it can't find. $('#emailForm') is not defined. Now, the #emailform isn't on the page, but it wasn't before either, and JS used to skip this and it would just work. Not sure why this is happening. Any clues?
