为什么以下脚本适用于IE和Safari而不是Firefox？
<html>
<head><script type="text/javascript">
function ShowHide(strTag ,strAttribute){
var elem = document.getElementsByTagName(strTag);
var elem1 = evt.srcElement || evt.target;
for (var i=0;i<elem1.children.length;i++){
elem1.children[i].innerText=="4" ? elem1.children
[i].innerText="6":elem1.children[i].innerText="4";
}
for (var i =0;i<elem.length;i++) {
if(elem[i].getAttribute(strAttribute)=="yes") {
elem[i].style.display=='none'? elem[i].style.display='block':elem
[i].style.display='none';
}
}
}
</script>
<div id=div1 onclick="ShowHide('div','exp2');">
<font face=Webdings color=BLACK>4</font> click here for some expandable
divs...</div>
<div id=div2 exp2='yes' style="display:none;">I'm a div!</div>
<div id=div3 exp2='yes' style="display:none;">More of them divs...</div>
<div id=div4 exp2='yes' style="display:none;">Me too! divs...</div>
</body>
</html>
