  • JQuery $.ajax doesn't return anything, but only in Google Chrome!?

    - by Shawson
    Hi All, I'm hoping someone can help me with this as I'm at a loss. I'm trying to simply load a plain text file into a page at runtime using jquery- everything works fine in IE8 (8.0.7600.16385), Firefox 3.6.3, however in Google Chrome 5.0.375.55 the "data" comes back as nothing- i get an empty alert box. This is the code i'm using; <!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"> <head> <title>Animation Test</title> <script type="text/javascript" language="javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> <script type="text/javascript" language="javascript"> $(document).ready(function () { $.ajax({ url: 'level1.txt', success: function (data) { alert(data); }, async: true, type: 'GET' }); }); </script> </head> <body> <canvas id="canvas" width="640" height="480"> Unsupported Browser </canvas> </body> </html> The file I'm loading in is a plain text file containing this; Central Cavern 100 O.........1.C....C...........1.O O................1.............O O..............................O O..............................O O......................B1..B...O O=============~~~~=~~~~========O O.............................1O O===...........................O O............A..OOO.B..........O O====...<<<<<<<<<<<<<<<<<<<<...O O............................==O O..............................O O..........B........OOO.....===O O....===============...........O O%............................XO O==============================O (Yes- it's the first level from Manic Miner! I'm making a javascript version using the html5 canvas to get my head around using it.) I'm at a total loss- it can't be the code because it runs in the other 2 browsers- is there an issue with jquery and this version of Chrome? Thanks for reading!! Shaw.

  • How to create javascript object from form elements using jQuery

    - by ob
    I'd like to be able to create a javascript object from my html form and am wondering if there's a good way to do this using jquery. I guess what i'm looking for is something similar to $.serialize, but which would result in a map instead of a string. <form> <input type="text" name="foo1" value="bar1" /> <input type="text" name="foo2" value="bar2" /> </form> desired result: { foo1:"bar1", foo2:"bar2" }

  • How to clear all form fields from code-behind?

    - by Slauma
    HTML has an input button type to reset all fields in a form to their initial state in one step: <input type="reset" ... />. Is there a similar simple way to reset all form fields of an aspx page from code-behind? Or is it necessary to reset all controls one by one with TextBox1.Text=string.Empty, TextBox2.Text=string.Empty, etc. ? Thanks in advance!

  • How to keep current selection for jqGrid pulldown edit

    - by WildBill
    When editing cells in jqGrid, specifically using a select pull-down to edit a cell, how does one make the current selection the current choice for that cell? In my page I have a cell where edittype:'select' is set but when one clicks on that row the value for that cells automatically changes to the first entry that my AJAX call returns. Is there something within JQGrid that needs to be set or does the object I send to jqGrid have to be of a certain format to do so?

  • Clojure evaluation without SLIME

    - by Denis
    Hi, I'm a starter with Emacs (but quite experienced Vim user) and trying to play with Emacs+Clojure combination. Maybe my setup will be unusual for Emacs world, as I'm not using SLIME/swank-clojure, but Emacs + eshell with running clojure REPL in it, mostly due simplicity (or probably because SLIME quite scares me off :D). So, maybe there is a Emacs guru that can help me here: does exists any shortcut (or maybe some elisp sample) to copy/paste code chunks (sexps) from editing buffer to eshell (and possibly execute it)? Thanks.

  • How to get Firefox to not continue to show "Transferring data from..." in browser status bar after a

    - by Edward Tanguay
    The following silverlight demo loads and displays a text file from a server. However, in Firefox (but not Explorer or Chrome) after you click the button and the text displays, the status bar continues to show "Transferring data from test.development..." which erroneously gives the user the belief that something is still loading. I've noticed that if you click on another Firefox tab and then back on the original one, the message goes away, so it seems to be just a Firefox bug that doesn't clear the status bar automatically. Is there a way to clear the status bar automatically in Firefox? or a way to explicitly tell it that the async loading is finished so it can clear the status bar itself?

  • matplotlib - write TeX on Qt form

    - by race1
    I'd like to add some TeX text to my Qt form, like label - just text, no graph, no lines, no borders, just TeX. I thought something like this: render TeX to bitmap and then place that bitmap on form, e.g. into QLabel. Or even better - use some backend, add it to form and use something tex_label.print_tex(<tex code>). Seems matplotplot has TeX parsers, but I can't figure out how to use them... Thanks.

  • Needed help with deleting rails cache

    - by WarDoGG
    I have been given a project of editing a website which is coded in RoR. However, the changes which i make in the view file is not visible immediately after a hard refresh but after 15-20 mins, the changes reflect. I am guessing this has something to do with the RoR caching system. Can someone please help me out ? The changes i made are purely HTML based like changing HTML attributes, filenames etc...
