怎样在js中判断一个字符串包不包含另外一个字符串

Answer 1

给你写了个例子，希望能帮上你的忙
<script language="javascript" type="text/javascript">
window.onload = function(){ getindex("aab","ab"); }

function getindex(str1,str2)
{
var isinclude = false;

if(str1.indexOf(str2) >= 0)
{ isinclude = true; }

if(isinclude)
{alert(str1 + "包含" + str2);}
else
{alert(str1 + "不包含" + str2);}
}
</script>
