JS驗證兩次輸入密碼是否相同

js中

 

<script>
function check()
{
with(document.all){
if(input1.value!=input2.value)
{
alert("false")
input1.value = "";
input2.value = "";
}
else document.forms[0].submit();
}
}
</script>

 

html代碼：

 

<FORM METHOD=POST ACTION="">
<input type="password" id="input1">
<input type="password" id="input2">
<input type="button" value="test"onclick="check()">
</FORM>

 

 

<script>
function f1()
{
if(document.theform.pswc.value!=document.theform.psw.value )
{
document.theform.pswc.focus();
return false;
}
else
{
return true;
}
}
</script>
<form name="theform">
<input type="text" id="pswc" name="pswc">
<input type="text" id=psw name="psw">
<input type="button" onclick=alert(f1())>
</form>

 

 

 

再加一個驗證兩次輸入密碼是否相同的JavaScript代碼

<script language="javascript">
function CheckForm()
if (document.form.PWD.value != document.form.PWD_Again.value) {
alert("您兩次輸入的密碼不一樣！請重新輸入.");
document.ADDUser.PWD.focus();
return false;
}
return true;
}
</script>
