这似乎是重复的问题,但请看一下并尝试回答。我的 javascript 验证功能不起作用。Javascript代码如下:
<script type="text/javascript">
var ck_name = /^[A-Za-z ]{3,20}$/;
var ck_email = /^([\w-]+(?:\.[\w-]+)*)@((?:[\w-]+\.)*\w[\w-]{0,66})\.([a-z]{2,6}
(?:\. [a-z]{2})?)$/i
var ck_mobile = /^[0-9]{10}$/;
var ck_address = /^[A-Za-z0-9-,]{40,100}$/;
function validate(myform){
var name = myform.fullname.value;
var email = myform.email.value;
var mobile = myform.mobile.value;
var address = myform.address.value;
var errors = [];
if (!ck_name.test(name)) {
errors[errors.length] = "Enter valid Name .";
}
if (!ck_email.test(email)) {
errors[errors.length] = "You must enter a valid email address.";
}
if (!ck_username.test(mobile)) {
errors[errors.length] = "Enter valid 10 digit mobile number .";
}
if (!ck_password.test(address)) {
errors[errors.length] = "You must enter a valid address min 40 char.";
}
if (errors.length > 0) {
reportErrors(errors);
return false;
}
return true;
}
function reportErrors(errors){
var msg = "Please Enter Valid Data...\n";
for (var i = 0; i<errors.length; i++) {
var numError = i + 1;
msg += "\n" + numError + ". " + errors[i];
}
alert(msg);
}
</script>
我有两个按钮 1) 提交和 2) 取消,当我单击提交按钮时,验证函数将调用,当我单击取消时,它会返回页面。
