楼主自己比较:
<script language="javascript" type="text/javascript">
function cmp1()
{
var no1 = document.getElementById("no1").value;
var no2 = document.getElementById("no2").value;
if (no1 > no2)
{ alert(no1+">"+no2); }
else if (no1 == no2)
{ alert(no1+"="+no2); }
else
{ alert(no1+"<"+no2);}
} function cmp2()
{
var no1 = parseInt(document.getElementById("no1").value);
var no2 = parseInt(document.getElementById("no2").value);
if (no1 > no2)
{ alert(no1+">"+no2); }
else if (no1 == no2)
{ alert(no1+"="+no2); }
else
{ alert(no1+"<"+no2);}
}
</script>
</HEAD><BODY>
<INPUT TYPE="text" id="no1" NAME="" value="65">
<INPUT TYPE="text" id="no2" NAME="" value="117"><br/>
<input type="button" value="Varities Not change type" onclick="cmp1();"><br/>
<input type="button" value="Varities change type" onclick="cmp2();"><br/>
</BODY>
</HTML>
不好意思,误解楼主意思,我本地测试两种情况都没问题,即可进行判断:
<script language="javascript" type="text/javascript">
function cmp1()
{
var no1 = document.getElementById("no1").value;
var no2 = document.getElementById("no2").value;
var no3 = no1-no2;
if (no3 > 0)
{ alert(no1+">"+no2); }
else if (no3 == 0)
{ alert(no1+"="+no2); }
else
{ alert(no1+"<"+no2);}
} function cmp2()
{
var no1 = parseInt(document.getElementById("no1").value);
var no2 = parseInt(document.getElementById("no2").value);
var no3 = no1-no2;
if (no3 > 0)
{ alert(no1+">"+no2); }
else if (no3 == 0)
{ alert(no1+"="+no2); }
else
{ alert(no1+"<"+no2);}
}
</script>
</HEAD><BODY>
<INPUT TYPE="text" id="no1" NAME="" value="65">
<INPUT TYPE="text" id="no2" NAME="" value="117"><br/>
<input type="button" value="Varities Not change type" onclick="cmp1();"><br/>
<input type="button" value="Varities change type" onclick="cmp2();"><br/>
</BODY>
</HTML>
先做类型转换吧，保险点儿
parseInt(65)
parseInt（$('a‘).value）>paese($('b').value)
不可以～
