Question

是否有一种将事件处理程序绑定到元素的简洁方法，而不管事件类型如何？

例如，我需要类似的东西：

$('#elem').bind(function(e){

    //do stuff for any event originating from this element
    e.stopPropagation();
});

您可以更改bind方法的默认行为。如果我们给出一个将起作用的参数，则将其添加到所有事件中看看这个。

$.fn.init.prototype.bind  = ( function( old ) {  

     return function( ) { 
        if( arguments.length == 1 && typeof arguments[0] === "function" ) { 
          // if we'll put to bind method one argument which is function 

          // list of whole of events - you set themselves as needed
          return this.bind( "click keydown keyup keypress mouseover mouseenter  mouseout mouseleave mousedown mouseup mousemove change blur focus scroll resize load unload beforeunload", arguments[0] );

        } else { 
            // trigger original bind method
            return old.apply( this, arguments ) 
        } ;
     }  

})( $.fn.init.prototype.bind );

现在：

$( "body" ).bind( function() { console.log( this ) } );

var eventsList = "blur, focus, load, resize, 
                scroll, unload, beforeunload, click, dblclick, 
                mousedown, mouseup, mousemove, mouseover, mouseout, 
                mouseenter, mouseleave, change, select, submit, keydown, 
                keypress, keyup, error";

(/*  selector of user choice   */).bind(eventsList, function(){

//All operations here..
});
