jquery - 将正则表达式添加到 jquery.validate

Question

需要向我的 jquery.validate 脚本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"
        },
    }
});

});

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的密码：

    <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"/>

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（例如密码或用户名）的最佳方法是什么：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.");

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
        }
    }

Answer 2

required: function(element){
    return /[a-zA-Z0-9]/.test($('#someConfirmPassword').val());
}

如果正则表达式通过，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。
