jQuery Validator:验证AlphaNumeric +空格和破折号 [英] jQuery Validator : Validate AlphaNumeric + Space and Dash

问题描述

我的网站上安装了jQuery验证插件(http://docs.jquery.com/Plugins/Validation).

I have jQuery validation plugins (http://docs.jquery.com/Plugins/Validation) installed on my website.

我正在使用此代码来验证文本字段中的字母数字，并且可以正常工作.但这不允许空格和破折号(-).

I'm using this code to validate alpha-numeric from text field, and it works. but it doesn't allow space and dash (-).

$.validator.addMethod("titleAlphaNum", function(value, element, param) 
{
return value.match(new RegExp("^" + param + "$"));
}); 

如何使其与空格和破折号一起使用?谢谢.

how to make it works with space and dash? thanks.

推荐答案

工作演示 http: //jsfiddle.net/cAADx/

/^[a-z0-9\-\s]+$/i应该可以解决问题！

g =/g修饰符可确保所有出现的替换"

g = /g modifier makes sure that all occurrences of "replacement"

i =/i使正则表达式匹配不区分大小写.

i = /i makes the regex match case insensitive.

希望这会有所帮助，

代码

$(function() {

    $.validator.addMethod("loginRegex", function(value, element) {
        return this.optional(element) || /^[a-z0-9\-\s]+$/i.test(value);
    }, "Username must contain only letters, numbers, or dashes.");

    $("#myForm").validate({
        rules: {
            "login": {
                required: true,
                loginRegex: true,
            }
        },
        messages: {
            "login": {
                required: "You must enter a login name",
                loginRegex: "Login format not valid"
            }
        }
    });

});​
