将正则表达式添加到jquery.validate

Question

需要在我的jquery.validate脚本中添加正则表达式检查.

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"
        },
    }
});

});

我想在用户输入数据时检查数据库中允许的密码特定字符:

    <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"/>

使用来自bassisstance的jquery.validate插件将正则表达式检查添加到必填字段(如密码或用户名)的最佳方法是:http://docs.jquery.com/Plugins/Validation

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.

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.");

而且,

...
$("#myBlahForm").validate({

    rules: {
        somePassword: {
            required: true ,
            //change regexp to suit your needs
            regx: /^(?=.*\d)(?=.*[a-z])(?=.*[A-Z])\w{6,}$/,
            minlength: 5,
            maxlength: 8
        }
    }
