MouseDown event

[Darko Drakulic]

Hi to all,

I need to call alert function in mouseDown event and it makes a problem when and object is selected. This fiddle is simplification of my problem:

http://jsfiddle.net/ddrakulic/KWW8P/7/

The problem is when point A is clicked. I need solution for this, so if you have any ideas, you are welcome. Is is possible to call mouseUp event from code or something like that?

All the best,
Darko

You can fire an event like this:

var brdyy = JXG.JSXGraph.initBoard('boxyy',{axis:false, boundingbox: [0, 28, 45, 0]});

brdyy.create("point", [15,15]);

brdyy.on("mousedown", function() {
    var evt = document.createEvent("MouseEvents");
    evt.initEvent("mouseup", true, true);
    document.dispatchEvent(evt);
    alert("click!");
});

This works on non-IE browsers. For a platform independent solution for firing events see e.g.

Best wishes,

Darko:

on your fiddle

changing mousedown to mouseup

brdyy.on("mouseup", function() {

   alert("click!");

});

works for me in safari, firefox and chrome

hope this helps

JSXGraph internal events can be trigger with trigger().

http://jsfiddle.net/migerh/KWW8P/8/

trigger() takes two arguments, first one is an array of the events that will be triggered, second (optional) argument is an array of parameters that will be given to the event handlers.

Thank you Alfred, your solution works.

Michael, your solution still have the same problem - point moves after click.

Seth, I know for that, but I need mouseup event (because for other functionality).

Thank you for all!
