我正在开发一个 asp.net mvc-5 Web 应用程序。我正在使用这些脚本：-
- jquery 1.10.2
- jquery-ui 1.8.24
- jQuery Validation Plugin 1.11.1
- jQuery 1.10.2
- jquery-ui 1.8.24
- jQuery 验证插件 1.11.1
Now when i run the application inside visual studio 2013, the following exception will happen on IE10 , while there will not be any problem on chrome or firefox :-
现在，当我在 Visual Studio 2013 中运行该应用程序时，IE10 上会发生以下异常，而 chrome 或 firefox 上不会出现任何问题：-
Unhandled exception at line 1234, column 5 in http://localhost:49392/Scripts/jquery.validate.js
0x800a138f - JavaScript runtime error: Unable to get property 'call' of undefined or null reference
the code which will raise the error inside the jquery.validate.js is :-
将在 jquery.validate.js 中引发错误的代码是：-
function($) {
// only implement if not provided by jQuery core (since 1.4)
// TODO verify if jQuery 1.4's implementation is compatible with older jQuery special-event APIs
if (!jQuery.event.special.focusin && !jQuery.event.special.focusout && document.addEventListener) {
$.each({
focus: 'focusin',
blur: 'focusout'
}, function( original, fix ){
$.event.special[fix] = {
setup:function() {
this.addEventListener( original, handler, true );
},
teardown:function() {
this.removeEventListener( original, handler, true );
},
handler: function(e) {
var args = arguments;
args[0] = $.event.fix(e);
args[0].type = fix;
return $.event.handle.apply(this, args);
}
};
function handler(e) {
e = $.event.fix(e);
e.type = fix;
**return $.event.handle.call(this, e);**//this will raise the exception
}
});
}
