Jquery验证插件，表单字段中没有url

我有一个问题，创建一个规则，将不允许url在表单字段的任何地方。只要稍微修改一下"url"规则，我就可以防止只输入没有文本的url，比如:

this is http://google.com allowed

这不是

http://google.com

jQuery.validator.addMethod("no_url", function(value, element, param) {
    return this.optional(element) || !(/^(https?|ftp):'/'/(((([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);

我希望能够阻止第一个例子，如果可能的话，但我缺乏这样做的技能，所以任何帮助都是非常欢迎的。
