开发没用到js框架所以自己写了个函数来获取dom元素代码如下
<html>
<body>
<div class="qq">sesdsds</div>
</body>
<script>
function getElementsByClassName(n) {
var classElements = [],allElements = document.getElementsByTagName('*');
for (var i=0; i< allElements.length; i++ )
{
if (allElements[i].className == n ) {
classElements[classElements.length] = allElements[i];
}
}
return classElements;
}
var test=getElementsByClassName("qq")[0].innerText;
alert(test);
</script>
</html>
?
