请教 jquery 中 trigger('click') 和 click() 的区别与优劣。

Question

$('#btn').trigger('click');$('#btn').click();求教这两种 click 事件的触发方式选择哪种更优？

Answer 1

jquery2的源码

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 ) {

        return arguments.length > 0 ?

            this.on( name, null, data, fn ) :

            this.trigger( name );

    };

});

看起来，$对象的click执行事件实现也是调用trigger……所以trigger更优？
