Jquery：表单验证不起作用
问题描述：
我是Jquery的新手，希望你们能帮助我解决这个jquery验证问题。
I am very new to Jquery and hope you guys can help me with this jquery validation problem.
一直试图验证表格，但根本没有验证。它接受我在字段中输入的任何内容，无论我设置了什么限制。
Been trying to validate the form but it does not validate at all. It accepts anything that I type in the field, regardless of what restrictions I set.
请帮忙。谢谢。
这是我的代码：
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js"></script>
<script src="http://ajax.microsoft.com/ajax/jquery.validate/1.7/additional-methods.js"></script>
<script src="http://ajax.aspnetcdn.com/ajax/jquery.validate/1.11.1/jquery.validate.js"></script>
<script type="text/javascript">
$(function(){
$('#form').validate({
alert("bbbb");

},
});
$("#submit").click(function(){

return false;
});
});
</script>
<div id="form">

答
你有2个元素 id =form，因此验证器被分配到 div 而不是表格。
You have 2 elements with the id="form", so the validator is assigned to the div not to the form.
更改 div 的 id 值>其他东西。
Change the id value of the div to something else.
此外 additional-methods.js 文件必须在 query.validate.js 并且由于 validate $中的 alert（）而出现语法错误c $ c> so
Also the additional-methods.js file must be added after query.validate.js and there is a syntax error because of the alert() within the validate so
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js"></script>
<script src="http://ajax.aspnetcdn.com/ajax/jquery.validate/1.11.1/jquery.validate.js"></script>
<script src="http://ajax.microsoft.com/ajax/jquery.validate/1.11.1/additional-methods.js"></script>
<div>
<center>
<form id="form">
<div class="col-xs-12">
<input type="text" name="name" id="name" placeholder="Name" required />
</div>
<div class="col-xs-12">
<input type="text" name="nric" id="nric" placeholder="NRIC" required />
</div>
<div class="col-xs-12">
<select class="dropdown" id="gender" onChange="changeColor(this)">
<option value="" disabled selected>Gender</option>
<option value="female">Female</option>
<option value="male">Male</option>
</select>
</div>
<div class="col-xs-12">
<input type="text" name="mobile" id="mobile" placeholder="Mobile" required />
</div>
<div class="col-xs-12">
<input type="text" name="address" id="address" placeholder="Address" required />
</div>
<div class="col-xs-12">
<input type="email" name="email" id="email" placeholder="Email" required />
</div>
<input id="submit" class="button" type="submit" value="submit"/>
</form>
</center>
</div>
然后
jQuery(function ($) {
$('#form').validate({
rules: {
name: {
required: true,
minlength: 2,
maxlength: 20,
lettersonly: true
},
ssn: {
required: true,
minlength: 9,
maxlength: 9,
nowhitespace: true
},
gender: {
required: true
},
mobile: {
required: true,
minlength: 10,
maxlength: 13,
digits: true
},
address: {
required: true,
minlength: 10,
},
email: {
required: true,
minlength: 6,
email: true
}
},
messages: {
name: {
required: "Please enter your name",
minlength: "Name should be more than 2 characters",
maxlength: "Name should be less than 20 characters",
lettersonly: "Name should contain only letters"
},
ssn: {
required: "Please enter your NRIC",
minlength: "NRIC should be more than 9 characters",
maxlength: "NRIC should be less than 9 characters",
nowhitespace: "NRIC should not have any spaces"
},
gender: {
required: "Please select your gender",
},
mobile: {
required: "Please enter your mobile number",
minlength: "Mobile number should be more than 10 characters",
maxlength: "Mobile number should be less than 13 characters",
digits: "Mobile number should contain only digits"
},
address: {
required: "Please enter your address",
minlength: "Address should be more than 10 characters",
},
email: {
required: "Please enter your email address",
minlength: "Password should be more than 6 characters",
email: "Please enter a valid email address"
}
},
});
});
