jquery源码调试，alert、console.log都不执行

[peter20091001]

jquery版本：1.8.3
jQuery.each( ("blur focus focusin focusout load resize scroll unload click dblclick " +
"mousedown mouseup mousemove mouseover mouseout mouseenter mouseleave " +
"change select submit keydown keypress keyup error contextmenu").split(" "), function( i, name ) {

// Handle event binding
jQuery.fn[ name ] = function( data, fn ) {
if ( fn == null ) {
fn = data;
data = null;
}
alert(name+"===:"+this===jQuery.fn[name]);
alert(name+"==:"+this==jQuery.fn[name]);
console.log("this===jQuery.fn[" + name + "]:" + this===jQuery.fn[name]);
console.log("this==jQuery.fn[" + name + "]:" + this==jQuery.fn[name]);

return arguments.length > 0 ?
this.on( name, null, data, fn ) :
this.trigger( name );
};

if ( rkeyEvent.test( name ) ) {
jQuery.event.fixHooks[ name ] = jQuery.event.keyHooks;
}

if ( rmouseEvent.test( name ) ) {
jQuery.event.fixHooks[ name ] = jQuery.event.mouseHooks;
}
});
把jquery-1.8.3.js文件引入html页面，打开这个页面，红色的那些语句都没执行。
求高手指教！

你这样写有问题吧 alert(name+"===:"+this===jQuery.fn[name]); alert(name+"==:"+this==jQuery.fn[name]); console.log("this===jQuery.fn[" + name + "]:" + this===jQuery.fn[name]); console.log("this==jQuery.fn[" + name + "]:" + this==jQuery.fn[name]); 浏览器控制台报错不

[usecf]

alert(name+"===:"+this===jQuery.fn[name]);改成alert(name+"===:this==="+jQuery.fn[name]);这种试试

帅哥，你忘记调用啦 jQuery.fn[name]();
