'innerText' works in IE, but not in Firefox
为什么以下脚本在 IE 和 safari 上有效，但在 Firefox 上无效？
<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');">
