Pet*_*gne 234 regex jquery jquery-validate
我正在使用jQuery验证插件.好东西!我想迁移现有的ASP.NET解决方案以使用jQuery而不是ASP.NET验证器.我错过了正则表达式验证器的替代品.我希望能够做到这样的事情:
$("Textbox").rules("add", { regularExpression: "^[a-zA-Z'.\s]{1,40}$" })
如何添加自定义规则来实现此目的？

感谢redsquare的回答,我添加了一个这样的方法:
$.validator.addMethod(
"regex",
function(value, element, regexp) {
var re = new RegExp(regexp);
return this.optional(element) || re.test(value);
},
"Please check your input."
);
现在您需要做的就是验证任何正则表达式是这样的:
$("#Textbox").rules("add", { regex: "^[a-zA-Z'.\\s]{1,40}$" })
此外,看起来有一个名为additional-methods.js的文件包含方法"pattern",当使用不带引号的方法创建时,它可以是RegExp.

你可以使用addMethod()
例如
$.validator.addMethod('postalCode', function (value) {
return /^((\d{5}-\d{4})|(\d{5})|([A-Z]\d[A-Z]\s\d[A-Z]\d))$/.test(value);
}, 'Please enter a valid US or Canadian postal code.');

我在制作一个jQuery正则表达式验证器时把所有部分放在一起有些麻烦,但我让它工作......这是一个完整的工作示例.它使用'验证'插件,可以在jQuery Validation Plugin中找到

没有理由将正则表达式定义为字符串.
$.validator.addMethod(
"regex",
function(value, element, regexp) {
var check = false;
return this.optional(element) || regexp.test(value);
},
"Please check your input."
);
和
telephone: { required: true, regex : /^[\d\s]+$/, minlength: 5 },
这样更好,不是吗？

延伸PeterTheNiceGuy的答案:
$.validator.addMethod(
"regex",
function(value, element, regexp) {
if (regexp.constructor != RegExp)
regexp = new RegExp(regexp);
else if (regexp.global)
regexp.lastIndex = 0;
return this.optional(element) || regexp.test(value);
},
"Please check your input."
);
这将允许您将正则表达式对象传递给规则.
$("Textbox").rules("add", { regex: /^[a-zA-Z'.\s]{1,40}$/ });
在对象上设置-flag lastIndex时,必须重置属性.否则它将从与该正则表达式的最后一次匹配的位置开始验证,即使主题字符串不同.gRegExp
我的其他一些想法是让你使用正则表达式的数组,以及另一个否定正则表达式的规则:
$("password").rules("add", {
regex: [
/^[a-zA-Z'.\s]{8,40}$/,
/^.*[a-z].*$/,
/^.*[A-Z].*$/,
/^.*[0-9].*$/
],
'!regex': /password|123/
});
但实施这些可能会太多.

正如addMethod文档中提到的:
请注意:虽然诱惑很大增加,检查是对值参数一个正则表达式的方法,它是干净多了封装自己的方法里面那些正则表达式.如果您需要许多略有不同的表达式,请尝试提取一个通用参数.正则表达式库:http://regexlib.com/DisplayPatterns.aspx
所以是的,你必须为每个正则表达式添加一个方法.开销很小,同时它允许你给正则表达式一个名字(不可低估),默认消息(方便)以及在不同地方重用它的能力,而不会反复重复正则表达式本身.

我让它像这样工作:
$.validator.addMethod(
"regex",
function(value, element, regexp) {
return this.optional(element) || regexp.test(value);
},
"Please check your input."
);
$(function () {
$('#uiEmailAdress').focus();
$('#NewsletterForm').validate({
rules: {
uiEmailAdress:{
required: true,
email: true,
minlength: 5
},
uiConfirmEmailAdress:{
required: true,
email: true,
equalTo: '#uiEmailAdress'
},
DDLanguage:{
required: true
},
Testveld:{
required: true,
regex: /^[0-9]{3}$/
}
},
messages: {
uiEmailAdress:{
required: 'Verplicht veld',
email: 'Ongeldig emailadres',
minlength: 'Minimum 5 charaters vereist'
},
uiConfirmEmailAdress:{
required: 'Verplicht veld',
email: 'Ongeldig emailadres',
equalTo: 'Veld is niet gelijk aan E-mailadres'
},
DDLanguage:{
required: 'Verplicht veld'
},
Testveld:{
required: 'Verplicht veld',
regex: '_REGEX'
}
}
});
});
确保正则表达式在/:-) 之间

您可以使用文件中pattern定义的additional-methods.js.请注意,在 jQuery Validate依赖项之后必须包含此additional-methods.js文件,然后您可以使用
$("#frm").validate({
rules: {
Textbox: {
pattern: /^[a-zA-Z'.\s]{1,40}$/
},
},
messages: {
Textbox: {
pattern: 'The Textbox string format is invalid'
}
}
});<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery-validate/1.17.0/jquery.validate.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery-validate/1.17.0/additional-methods.min.js"></script>
<form id="frm" method="get" action="">
<fieldset>
<p>
<label for="fullname">Textbox</label>
<input id="Textbox" name="Textbox" type="text">
</p>
</fieldset>
</form>这是工作代码。
function validateSignup()
{
$.validator.addMethod(
"regex",
function(value, element, regexp)
{
if (regexp.constructor != RegExp)
regexp = new RegExp(regexp);
else if (regexp.global)
regexp.lastIndex = 0;
return this.optional(element) || regexp.test(value);
},
"Please check your input."
);
$('#signupForm').validate(
{
onkeyup : false,
errorClass: "req_mess",
