jQuery hasClass（）在IE 11中不起作用，但在Chrome和Firefox中起作用

Question

I have the below piece of code which works perfectly in Chrome and Firefox , but in IE 10 and 11 , it is not working.

Also when I open the Developer Tools in IE ,it works correctly.

Can anyone help out?

$("body" ).on( "click", ".js-save-request-meta", function(event) {
    event.preventDefault();
    var el = $(this);
    var meta_value = el.data('meta-value') || $('input[name="meta_value"]').val();
     if(el.hasClass('aspect-is-selected')){
        $.post( "../ajax/delete_Request_Meta.php", {meta_value:meta_value,request_id:RequestData.request_id} )
        .done(function( data ) {
            showMessage( data );                       
         });

    }else{

        $.post( "../ajax/save_Request_Meta.php", {meta_value:meta_value,request_id:<?=$request['request_id']?> } )

         .done(function( data ) {
            showMessage( data );              
                }      
           });     
});

try adding missing function

var isFunc = $.isFunction($.fn.lettering);

if (!isFunc){
  jQuery.fn.yourfunctionname = function() {
    return new RegExp(' ' + className + ' ').test(' ' + this[0].className + ' ');
  };
}

This issue is caused due to caching problem. This can be rectified by changing the settings in the browser to clear cache and refresh from server. But IE 11 still has issue with the refreshing of cache.

But the code works fine in IE 10. Thanks!
