问题 Today i have observed the following in a Jquery code: $.ajaxSetup({ cache: false }); What does this mean? And what happens if the value of cache turns True .

问题 I am trying to implement server side filtering for a Kendo UI grid (client only). I am not sure how to pass the filter operator and value entered on the filter box.

问题 I have an accordion with 2 pane. The thing is if I set it to autosize="Limit" and selectedindex="0", when load the first time, in IE 9, it works perfectly fine but in firefox/chrome, the size of the content pane is smaller than the content. But if I close and open back the pane, it will work fine. If I set it to selectedindex="-1", in IE9 it will work fine where all the pane will collapse, however in chrome/firefox, It fully open the first pane. How can I make it to fully open in all browser.
