event.target not working on Firefox
提问by niko
var x = event.target||event.srcElement;
document.getElementById(x.id).style.left = 200 + "px" ;
document.getElementById(x.id).style.top = 100 + "px" ;
Works fine on google chrome and IE but not on firefox. Tried it on google. google says event.srcElement(works on IE but not on firefox) so i have added event.target but still not working. Is there anymore changes I need to do to work on firefox? By the way Im using 3.5 version of firefox.
在 google chrome 和 IE 上工作正常,但在 Firefox 上不工作。在谷歌上试过。谷歌说 event.srcElement(适用于 IE 但不适用于 firefox)所以我添加了 event.target 但仍然无法正常工作。在 Firefox 上工作我还需要做些什么改变吗?顺便说一下,我使用的是 3.5 版的 Firefox。
function up()
{
dragok = false;
document.onmousemove = null;
var x = event.target||event.srcElement;
document.getElementById(x.id).style.left= 200 + "px" ;
document.getElementById(x.id).style.top= 100 + "px" ;
}
Please help me to make it work on firefox

Make sure you define eventas a formal parameter to the handler.
确保您定义event为处理程序的形式参数。
IEdefines it globally, and Chromedefines it both in both places, so it works either way, but Firefoxonly defines it as a function parameter.
IE全局定义它,并Chrome在两个地方都定义它,因此它可以以任何方式工作,但Firefox仅将其定义为函数参数。
function up( e ) {
// ^-----------------------------------------------------+
if( !e ) e = window.event; // <---needed this --- and this ->--+
dragok = false;
document.onmousemove = null;
var x = e.target||e.srcElement; // <--- and these
document.getElementById(x.id).style.left= 200 + "px" ;
document.getElementById(x.id).style.top= 100 + "px" ;
}

I solved my problem using Jquery. For example to get the id of a element you can use:

This solution to work in Firefox browser too. When start keydownaction then its set the eventproperty to global variable like this.
此解决方案也适用于 Firefox 浏览器。当开始keydown动作时,它会event像这样将属性设置为全局变量。
var keyEvent=null;
Assign that eventproperty to keyEventand .itemis target element.
该分配event财产keyEvent,并.item为目标元素。
$(document).on("keydown",'.item', function(e){
keyEvent=e;
},this))
then.Use keyEventin your code.
然后。keyEvent在您的代码中使用。
function up( e ) {
if( !e ) e = keyEvent;
dragok = false;
document.onmousemove = null;
var x = e.target||e.srcElement;
document.getElementById(x.id).style.left= 200 + "px" ;
document.getElementById(x.id).style.top= 100 + "px" ;
}
Note: Don't try to set the eventproperty to global variable of window.
注意:不要尝试将event属性设置为 的全局变量window。
