When the extension Object prototype object, if it is not a function, or function for some special treatment, sends a Ajax request, in the code：

for (I in {success: 1, error: 1, complete: 1}) {

jqXHR[ i ]( s[ i ] );

}

An error occurs.

Chinese is as follows:

当扩展Object原型对象后，如果其不是一个函数，或者函数进行了一些特殊处理，发送Ajax请求后，在

for ( i in { success: 1, error: 1, complete: 1 } ) {

jqXHR[ i ]( s[ i ] );

}

会发生错误
