add regex to jquery.validate
提问by isaac weathers
Need to add a regex check to my jquery.validate script.
需要向我的 jquery.validate 脚本添加正则表达式检查。
I have this:
我有这个：
$().ready(function() {
$("#myBlahForm").validate({
rules: {
someName: {
required: true,
minlength: 5,
maxlength: 8,
},
somePassword: {
required: true,
minlength: 5,
maxlength: 8,
},
someConfirmPassword: {
required: true,
equalTo: "#somePassword"
},
},
messages: {
someName: {
required: "Please create your username",
},
somePassword: {
required: "Please create a password",
},
someConfirmPassword: {
required: "Please re-enter your password",
equalTo: "Passwords must match"
},
}
});
});
});
And I would like to check for specific characters that are allowed in the DB for passwords when the user enters their data here:
当用户在此处输入数据时，我想检查数据库中允许的特定字符以获取密码：
<label for="someName">Username</label>
<input type="text" id="someName" name="someName" placeholder="Create a Username"/>
<label for="somePassword">Password</label>
<input type="password" id="somePassword" name="somePassword" placeholder="Create a Password"/>
<label for="someConfirmPassword">Confirm Password </label>
<input type="password" id="someConfirmPassword" name="someConfirmPassword" placeholder="Verify your Password"/>
What's the best way to add a regex check to a required field such as a password or username using jquery.validate plugin from bassisstance: http://docs.jquery.com/Plugins/Validation
使用bassisstance的jquery.validate插件将正则表达式检查添加到必填字段（例如密码或用户名）的最佳方法是什么：http://docs.jquery.com/Plugins/Validation
Basically, I need to make sure that the password and usernames they create only have 0-9, letters, and a couple of special characters.
基本上，我需要确保他们创建的密码和用户名只有 0-9、字母和几个特殊字符。

well, you could add your custom validation method using addMethod, like
好吧，您可以使用添加自定义验证方法addMethod，例如
$.validator.addMethod("regx", function(value, element, regexpr) {
return regexpr.test(value);
}, "Please enter a valid pasword.");
And ,
和 ，
...
$("#myBlahForm").validate({
rules: {
somePassword: {
required: true ,
//change regexp to suit your needs
regx: /^(?=.*\d)(?=.*[a-z])(?=.*[A-Z])\w{6,}$/,
minlength: 5,
maxlength: 8
}
}

required: function(element){
return /[a-zA-Z0-9]/.test($('#someConfirmPassword').val());
}
Above expression will return true if regexp passes, false if it doesn't. Change it to fit your needs.
如果正则表达式通过，则上面的表达式将返回 true，否则返回 false。更改它以满足您的需求。
