Question

所以我有一个表格可以让用户通过网址上传图片和youtube视频。

我正在使用jquery验证插件来验证图像的URL，如下所示：

jQuery.validator.addMethod("complete_url", function(val, elem) {
    // if no url, don't do anything
    if (val.length == 0) { return true; }

    // if user has not entered http:// https:// or ftp:// assume they mean http://
    if(!/^(https?|ftp):\/\//i.test(val)) {
        val = 'http://'+val; // set both the value
        $(elem).val(val); // also update the form element
    }
    // now check if valid url
    // http://docs.jquery.com/Plugins/Validation/Methods/url
    // contributed by Scott Gonzalez: http://projects.scottsplayground.com/iri/
    return /^(https?|ftp):\/\/(((([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(%[\da-f]{2})|[!\$&amp;'\(\)\*\+,;=]|:)*@)?(((\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})|[!\$&amp;'\(\)\*\+,;=]|:|@)+(\/(([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(%[\da-f]{2})|[!\$&amp;'\(\)\*\+,;=]|:|@)*)*)?)?(\?((([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(%[\da-f]{2})|[!\$&amp;'\(\)\*\+,;=]|:|@)|[\uE000-\uF8FF]|\/|\?)*)?(\#((([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(%[\da-f]{2})|[!\$&amp;'\(\)\*\+,;=]|:|@)|\/|\?)*)?\.(gif|jpg|jpeg|png)$/i.test(val);
});

然后：

$( "#urlpostform" ).validate({
  rules: {
    imageurl: {
      required: true,
      complete_url: true
    }

这是我检查提交的网址以JPG | PNG | JPEG | GIF结尾及其工作方式的方式。

现在我想添加条件来验证提交的网址是以太网Youtube视频还是IMAGE。

这是检查提交的网址是否为YouTube视频的正则表达式：

^http:\/\/(?:www\.)?youtube.com\/watch\?(?=[^?]*v=\w+)(?:[^\s?]+)?$

但我不知道如何让它在同一输入中协同工作以验证以太网youtube网址或图片网址。

我怎样才能做到这一点？

Answer 1

我无法测试，但也许是这样的：

jQuery.validator.addMethod("complete_url", function(val, elem) {
// if no url, don't do anything
if (val.length == 0) { return true; }

// if user has not entered http:// https:// or ftp:// assume they mean http://
if(!/^(https?|ftp):\/\//i.test(val)) {
    val = 'http://'+val; // set both the value
    $(elem).val(val); // also update the form element
}

var imgRegex = new Regex("/^(https?|ftp):\/\/(((([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(%[\da-f]{2})|[!\$&amp;'\(\)\*\+,;=]|:)*@)?(((\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})|[!\$&amp;'\(\)\*\+,;=]|:|@)+(\/(([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(%[\da-f]{2})|[!\$&amp;'\(\)\*\+,;=]|:|@)*)*)?)?(\?((([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(%[\da-f]{2})|[!\$&amp;'\(\)\*\+,;=]|:|@)|[\uE000-\uF8FF]|\/|\?)*)?(\#((([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(%[\da-f]{2})|[!\$&amp;'\(\)\*\+,;=]|:|@)|\/|\?)*)?\. (gif|jpg|jpeg|png))";
var youtubeRegex = new Regex("^http:\/\/(?:www\.)?youtube.com\/watch\?(?=[^?]*v=\w+)(?:[^\s?]+)?$");

//determine the url
if(imgRegex.test(val) == true)
    return true;
else if(youtubeRegex.test(val) == true)
    return true;
else
    return false;
});

以上将首先检查它是否是图像，如果不是，它将检查它是否是Youtube URL。另一个功能保持不变：

$( "#urlpostform" ).validate({
rules: {
imageurl: {
  required: true,
  complete_url: true
}

这有点类似于你的想法吗？

Answer 2

这也有效，

$.validator.addMethod("youtube_url",function(value, element) {
                return this.optional(element) || /^https:\/\/(?:www\.)?youtube.com\/watch\?(?=[^?]*v=\w+)(?:[^\s?]+)?$/i.test(value); 
            },
            "Invalid Youtube Url"
    );


$( "#urlpostform" ).validate({
rules: {
imageurl: {
  required: true,
  youtube_url: true
}

正则表达式检查有效的URL是Youtube VIDEO还是IMAGE URL
