关于click的问题
onclick是好用。。可是怎么触发它的click事件呢？
<input id= "wc_1 " type= "file " />
<script type= "text/javascript ">
var $ = function (id) {
return document.getElementById(id);
};
window.onload = function () {
var t = $( "wc_1 ");
if (!document.createEvent) t.click();
else {
//var e = t.ownerDocument.createEvent( "MouseEvents ");
var e = document.createEvent( "MouseEvents ");
e.initEvent( "click ", false, true);
t.dispatchEvent(e);
}
}
</script>
[解决办法]
object.fireEvent( "onclick ");
[解决办法]
<input id= "aa " type=button onclick= "alert( 'aaaa ') ">
<script>
var a=document.getElementById( "aa ");
aa.click();
</script>
FF下，没问题啊
