asp.net javascript jquery
I’m trying to call a Page Method using a jQuery ‘attached’ event function, in which I like to use the closure to keep the event target local, as below, but page method calls declare several ‘error’ functions, and I would like to use one function for all of them. If, in the below code, I was handling an error and not success, how could I use my single, anonymous handler for all 3 error functions?$(“:button”).click(function () {var button = this;PageMethods.DoIt(function (a, b, c) {alert(button);

javascript
I’m trying to change the value of a text input field based on user actions. I’m doing it like this:document.getElementById(textFieldID).value = newValue;It isn’t quite working — the original text in the field remains on the screen, unchanged. However, when I submit the form, it behaves as though the value was indeed changed correctly. (And a debug alert confirms that yup, I’m hitting that bit of the code and passing in the right field ID and text value.) Anybody have any insights? Is there

javascript html ajax mootools
I’m trying to build some JavaScript in MooTools that fetches table row markup from the server, then adds it to a table. I have an object named htmlAjax that’s set as a MooTools Ajax object.

python sql django tdd models
Racking my brain on this one. The model seems true, theoretically all of the commented permutations should work— but the only things that can successfully retrieve the user is .filter and .all; .get doesnt work; I can deal with using either .filter or .all —- but why isn’t get working? I’ll reiterate that a direct SQL query works 100% in this case. All imports are in place and things are functioning great at a low level — again, Filter works, All works, but get fails for some reason. class

The error I receive is: cannot read property ‘children’ of null.Does anyone know if I’m missing something? I can’t imagine why Chrome would error out on such a basic line.This is part of an MVC 4 project if that makes any difference.Thank you in advance!

I have an SVG document hereOn firefox, everything works as expected. However, google chrome appears to think this line:<image … xlink:href=”/textures/Cube top.png” />references http://minecraft-cube.comuv.com/index.svg, not http://minecraft-cube.comuv.com/textures/Cube top.png, resulting in unexpected recursion.Obviously, I’d much prefer it if it used the image I specify.What is going on here?EDIT: Filed bug #68732 in Chrome. May still be doing something wrong though.
