ajax - 3 clicks with a confirm javascript window? -


hi taking 3 clicks excute command javascript confirm prompt. code nested in handle-request ajax function. here code, dont know why doing this?

closebutton.onclick = function() {     node.setdata('alpha', 0, 'end');     node.eachadjacency(function(adj) {       adj.setdata('alpha', 0, 'end');         var requestone = createrequest();         var deletenode = node.id;         var vars = "deletenode=" + encodeuricomponent(deletenode);            requestone.open("post", "deletenode.php", true);            requestone.setrequestheader("content-type", "application/x-www-form-urlencoded");        if (confirm('are sure want delete species database?')) {            requestone.onreadystatechange = function()            {            handlerequest(requestone);            };           requestone.send(vars);           fd.fx.animate({          modes: ['node-property:alpha',                'edge-property:alpha'],          duration: 500         });   } else {   // nothing!  }      });

it doesn't mean that, required 3 clicks. have wait until operation complete. response. means readystate becomes 4.

readystate 1 of property of httprequest. indicates current state of object.

there 5 states.
0 - uninitialized (unsent)
1 - loading (opened)
2 - loaded (headers_received)
3 - interactive (loading)
4 - complete (done)
