推荐答案

如果您查看jQuery代码，您会发现click()的全部工作是执行trigger('click'):

If you look at the jQuery code you can see that all click() does is execute trigger('click'):

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

请注意:

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

换句话说，如果没有参数传递给click，请执行trigger('click')".

In other words, "If no arguments are passed to click, execute trigger('click')".
