  • jquery .get/.post not working on ie 7 or 8, works fine in ff

    - by Samutz
    I have basically this on a page: <script type="text/javascript"> function refresh_context() { $("#ajax-context").html("Searching..."); $.get("/ajax/ldap_search.php", {cn: $("#username").val()}, function(xml) { $("#ajax-context").html($("display", xml).text()); $("#context").val($("context", xml).text()); }, 'xml'); } $(document).ready(function() { $("#username").blur(refresh_context); }); </script> <input type="text" name="username" id="username" maxlength="255" value="" /> <input type="hidden" name="context" id="context" value=""/> <div id="ajax-context"></div> What it should do (and does fine on Firefox) is when you type a username in to the #username field, it will run /ajax/ldap_search.php?cn=$username, which searches our company's ldap for the username and returns it's raw context and a formatted version of the context like this: <result> <display>Staff -&gt; Accounting -&gt; John Smith</display> <context>cn=jsmith,ou=Accounting,ou=Staff,ou=Users,o=MyOrg</context> </result> The formatted version (display) goes to the div #ajax-context and goes to the hidden input #context. (Also, the - are actually - "& g t ;" (without spaces)). However, on IE the div stays stuck on "Searching..." and the hidden input value stays blank. I've tried both .get and .post and neither work. I'm sure it's failing on the .get because if I try this, I don't even get the alert: $.get("/ajax/ldap_search.php", {cn: $("#username").val()}, function() { alert("Check"); }); Also, IE doesn't give me any script errors. Edit: Added "$(document).ready(function() {", the .blur was already in it in my code, but I forgot to include that in my post. Edit 2: The request is being sent and apache2 is receiving it: 10.135.128.96 - - [01/May/2009:10:04:27 -0500] "GET /ajax/ldap_search.php?cn=i_typed_this_in_IE HTTP/1.1" 200 69

  • C++ variable alias - what's that exactly, and why is it better to turn if off?

    - by Poni
    I've read the essay Surviving the Release Version. Under the "Aliasing bugs" clause it says: You can get tighter code if you tell the compiler that it can assume no aliasing.... I've also read Aliasing (computing). What exactly is a variable alias? I understand it means using a pointer to a variable is an alias, but, how/why does it affect badly, or in other words - why telling the compiler that it can assume no aliasing would get me a "tighter code"

  • Is there a link to the "latest" jquery library on Google APIs?

    - by Nick Pierpoint
    I use the following for a jquery link in my <script> tags: http://ajax.googleapis.com/ajax/libs/jquery/1.2.6/jquery.js Just wondered if anyone had discovered whether there's a link to the "latest" version: Something like the following (which doesn't work): http://ajax.googleapis.com/ajax/libs/jquery/latest/jquery.js (Obviously not necessarily a great plan to link your code to potentially changing libraries but useful in development)

  • Differences between Zend Framework 1.8 and 1.10

    - by Pat
    I want to start learning Zend Framework. My only concern is that the most recent ZF book on Amazon with good reviews teaches version 1.8 of the framework, which is now about a year old. Do you think it would be a good idea to still pick up that book or is it too old now?

    Hii, Any one knows how to upload files to the physical location of the server. It is possible using file upload control that i know. But i want to avoid the external postbacking of the page. For e.g exactly like what in the yahoo mail did. In yahoo mail latest version if you attach a file that won't post back and attach that file in to server. What is the technology behind that?

  • Fast matrix transposition in Python

    - by psihodelia
    Is there any fast method to make a transposition of a rectangular 2D matrix in Python (non-involving any library import).? Say, if I have an array X=[[1,2,3], [4,5,6]] I need an array Y which should be a transposed version of X, so Y=[[1,4],[2,5],[3,6]].

  • Why does refreshing a page with a google map often fail?

    - by Shawn
    I'm working on a website that needs google maps, and testing is being a bitch because refreshing the page very often fails (hangs endlessly) so I need to go to a different page and come back in order to test the new version of the code. I have noticed that refreshing the page only fails on pages with maps, so I'm guessing these are related. Does anyone have a clue?

  • relaunch app when it ends or when it prints out certain text (stdout)

    - by acidzombie24
    I have an app which acts almost like a daemon. Sometimes it quits on error and many times it prints an error msg then ask users to press any key to close. How can i relaunch the app when either case happens? I am more interested in the 2nd case. I can do this in c++, C# or python. The script is an old python that i dont want to change (a newer c# version is in the works but not stable)
