jQuery modal dialog cancel button isn't working

I am using jQuery modal dialog in my web application. I have used one button (cancel) and want to close dialog by clicking on it but it's not working, while disable & destroy is working.

any idea please....

Code :

$("#dialog-form" ).dialog({
          ....
         buttons: {
             Cancel: function() {
          $( this ).dialog( "close" );  // dialog doesn't close

         //   $( this ).dialog( "destroy" ); (it's working)
         //   $( this ).dialog( "disable" ); 开发者_Python百科(it's working)
 } 

I realized now, it was my silly question but i hope it'd be helpful to someone. The problem i was getting due to missing of several files.e.g : There is a CSS file eithier we can use by linking directly or just download the file and put it in your web application and then link to your own server.

solution 1 :

<link rel="stylesheet" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/themes/base/ui.all.css"/>

solotion 2 : just download the css file and put it in your server. as i downloaded a css file called jquery.ui.all.cssand put this inside of my webApplication/lib. Now i can linked

<link rel="stylesheet" href="my_web_app/lib/jquery.ui.all.css"/>

but here is a big deal, you need to check the file if it is importing some other files or not, as i went through this file and found that it is importing two other files.

@import "jquery.ui.base.css";
@import "jquery.ui.theme.css";

This is what i was making mistake, again i downloaded these two files separately and put it in the same folder of my web app (my_web-App/lib/.....).

Problem due to jQuery file : make sure you always use the updated version of jQuery file. This is where i got stuck but finally i found that i am using the old version (jQuery v1.3.2) of jQuery file while i was needed latest one (jQuery v1.6.2).
