JS方式 onkeyup="validate()"是引用方法的方式
<script>
function validate() {
var pwd1 = document.getElementById("pwd").value;
var pwd2 = document.getElementById("pwd1").value;
<!-- 對比兩次輸入的密碼 -->
if(pwd1 == pwd2)
{
document.getElementById("tishi").innerHTML="<font color='green'>兩次密碼相同</font>";
document.getElementById("button").disabled = false;
}
else {
document.getElementById("tishi").innerHTML="<font color='red'>兩次密碼不相同</font>";
document.getElementById("button").disabled = true;
}
}
</script>
Jquery方法
<script>
function validate() {
var pwd = $("#pwd").val();
var pwd1 = $("#pwd1").val();
<!-- 對比兩次輸入的密碼 -->
if(pwd == pwd1)
{
$("#tishi").html("兩次密碼相同");
$("#tishi").css("color","green");
$("#xiugai").removeAttr("disabled");
}
else {
$("#tishi").html("兩次密碼不相同");
$("#tishi").css("color","red")
$("button").attr("disabled","disabled");
}
}
</script>
