RegEx在jQuery Validator addMethod中 [英] RegEx in jQuery Validator addMethod

问题描述

我的jQuery验证器自定义方法需要一些RegEx。我认为第一个容易的只是将用户名限制为只有美国字母，数字和没有特殊字符。我想出了 ^ [a-zA-Z0-9] + $ 但它似乎不起作用。也许是因为它出现在函数中的方式：

I need a few RegEx for my jQuery validator custom methods. The first which I thought was going to be easy was just limiting a username to only US letters, numbers, and no special characters. I came up with ^[a-zA-Z0-9]+$ but it doesn't seem to work. Maybe it is due to the way it appears in the function:

$.validator.addMethod(
    "legalName",
    function(value, element) {
        return (element.value != "^[a-zA-Z0-9]+$");
    },
    "Use a valid username."
);

第二个是验证密码，这个限制与增加所需的确定数量基本相同字符，如大写，数字等。我想，一旦我得到用户名RegEx，密码就不会太难，只需要在 {1} 中填写表达式。

The second is validating the password which is essentially the same limitations with the addition of a required number of certain characters such as an uppercase, number, ect. I figure once I get the username RegEx down the password wont be too hard, just a matter of fitting in {1}'s and such within the expression.

我的问题的最后一部分是如何在原始 .addMethod 中添加第二种方法（legalPassword）或我需要创建一个完整的其他 $。validator.addMethod ？

The last part of my question is how do I add a second method ("legalPassword") inside of the original .addMethod or do I need a create a whole other $.validator.addMethod?

$(document).ready(function() {
    $("#form1").validate({
        rules: {
            username: {
                legalName: true,
                required: true,
                maxlength: 35
            }
        },
    });
});

和表格代码：

<form id="form1" method="post" action="">
  <div class="form-row"><span class="label">Username *</span><input type="text" name="username" /></div>
  <div class="form-row"><input class="submit" type="submit" value="Submit"></div>
</form>

新代码（仍无效）：

$.validator.addMethod(
    "legalName",
    function(value, element) {
        /^[a-zA-Z0-9]+$/.test( value );
    },
    "Use a valid username."
);

推荐答案

返回this.optional（元素）|| / ^ [a-zA-Z0-9] + $ / .test（value）;
