JS验证两次输入密码是否相同

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代码：

<FORM METHOD=POST ACTION="">

<input type="password" id="input1">

<input type="password" id="input2">

<input type="button" value="test"οnclick="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" οnclick=alert(f1())>

</form>

再加一个验证两次输入密码是否相同的JavaScript代码

<script language="javascript">

function CheckForm()

if (document.form.PWD.value != document.form.PWD_Again.value) {

alert("您两次输入的密码不一样！请重新输入.");

document.ADDUser.PWD.focus();

return false;

}

return true;

}

</script>
