jQueryUI可拖动，触发“停止”事件

Question

The object that i must drag can also be moved by the event of the keyboard (key up , down , left and top)

In the drag event of any object i have a function that do something , and when the object is moved by the keyboard i must call the drag stop event

All of this solutions doesn't work

Jquery .trigger('stop') method for .draggable

$("#obj").draggable().trigger("dragstop");

$("#obj").trigger("dragstop");

How would you use Trigger to fire the jquery draggable start, drag, stop events?

var s = [{ClientX:0, ClientY:0, target:""},{}];
$("#obj").draggable("option" , "stop").apply($("#obj") , s);

Answer 1

I believe you're binding the stop ( or any other ) event while initializing as follows:

$("#draggable").draggable({
 stop: function(ev,ui){
 }
});

In that case, trigger won't work.

Bind the event separately,

for example:

$("#draggable").on("dragstop",function(ev,ui){

});

Then trigger will work.

 $("#draggable").draggable(); $("#draggable").on("dragstop", function(ev, ui) { alert("draggable stop"); }); $("button").click(function(){ $("#draggable").trigger("dragstop"); }); 

 #draggable { width: 50px; height: 50px; background: dodgerblue; }
