Question

我无法使自定义网址验证规则有效。

我正在添加新规则：

 jQuery.validator.addMethod("complete_url", function(val, elem) {
// if no url, don't do anything
  return  /((([A-Za-z]{3,9}:(?:\/\/)?)(?:[-;:&=\+\$,\w]+@)?[A-Za-z0-9.-]+|(?:www.|[-;:&=\+\$,\w]+@)[A-Za-z0-9.-]+)((?:\/[\+~%\/.\w-_]*)?\??(?:[-\+=&;%@.\w_]*)#?(?:[\w]*))?)/.test(val);
    });
 ...
 $("#new_website").validate({
    rules: {
          url: "complete_url",
         'website[url]': {
            url: true,
            required: true}
           }
        });

但它会让我回头

   invalid URL

我在这里检查了正则表达式 - http://www.rubular.com/。它工作正常，但我的自定义验证器失败了。

我做错了什么？

Answer 1

请不要使用正则表达式。甚至不使用jQuery验证器使用的相同正则表达式，它可能会在未来发生变化，并且您无法利用这些更新。这是这样做的方法：

$.validator.addMethod('validUrl', function(value, element) {
        var url = $.validator.methods.url.bind(this);
        return url(value, element) || url('http://' + value, element);
    }, 'Please enter a valid URL');

Answer 2

  jQuery.validator.addMethod("checkurl", function(value, element) {
// now check if valid url
return /^(www\.)[A-Za-z0-9_-]+\.+[A-Za-z0-9.\/%&=\?_:;-]+$/.test(value);
}, "Please enter a valid URL."
);

 // connect it to a css class
  jQuery.validator.addClassRules({
checkurl : { checkurl : true }    
 });
  ...
    'website[url]': {
            checkurl: true
    }

我用过它并且效果很好

jQuery.validator.addMethod("url2", function(value, element, param) {
return this.optional(element) || /^(www\.)(((([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(%[\da-f]{2})|[!\$&'\(\)\*\+,;=]|:)*@)?(((\d|[1-9]\d|1\d\d|2[0-4]\d|25[0-5])\.(\d|[1-9]\d|1\d\d|2[0-4]\d|25[0-5])\.(\d|[1-9]\d|1\d\d|2[0-4]\d|25[0-5])\.(\d|[1-9]\d|1\d\d|2[0-4]\d|25[0-5]))|((([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])*([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])))\.)*(([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])*([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])))\.?)(:\d*)?)(\/((([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(%[\da-f]{2})|[!\$&'\(\)\*\+,;=]|:|@)+(\/(([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(%[\da-f]{2})|[!\$&'\(\)\*\+,;=]|:|@)*)*)?)?(\?((([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(%[\da-f]{2})|[!\$&'\(\)\*\+,;=]|:|@)|[\uE000-\uF8FF]|\/|\?)*)?(#((([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(%[\da-f]{2})|[!\$&'\(\)\*\+,;=]|:|@)|\/|\?)*)?$/i.test(value);
}, jQuery.validator.messages.url);

如何在没有http的情况下进行url验证（或在验证通过后添加它）？
