怎么不输出why呢？

Question

<script type="text/javascript">
var love=document.getElementById("wo").innerHTML.substr(0,6);
     if love=="name";
alert(love);
else 
alert(why);
</script>

Answer 1

why是变量吗，前面好象没有声明，如果是字符串，则需要加个引号~

Answer 2

<div id="wo">0name123456789</div>
<script type="text/javascript">
var why='kk';
var love=document.getElementById("wo").innerHTML.substr(0,4);
  if(love=="name")
alert(love);
else  
alert(why);
</script>

Answer 3

<script type="text/javascript">
var love=document.getElementById("wo").innerHTML.substr(0,6);
  if love=="name";
alert(love);
else  
alert("why");
</script>
why如果是字符串的话，请加引号！

Answer 4

<script type="text/javascript">
var love=document.getElementById("wo").innerHTML.substr(0,6);
  if (love=="name")
alert(love);
else 
alert("why");
</script>
楼主，多看些语法规则，多看没坏处，省得以后翻旧账。

Answer 5

no love, no reason, don't ask "why?"
