问题描述

我做验证我的的Youtube URL文本字段

I am doing validation for my Youtube url text field.

我需要检查,如果的Youtube URL不存在我应该抛出错误,我跟这个的答案并创建了的jsfiddle 进行检查。

I need to check, if the Youtube url does not exist I should throw error, I followed this answer and created the jsfiddle to check it.

它适用于有效的URL,但它不会为无效的网址工作。我看到的是404错误网​​络控制台

It works for valid url but it does not work for invalid url. All I see is 404 error in network console

有没有一种方法来检查,如果网址在客户端存在使用的JavaScript 的jQuery

Is there a way to check if url exist in client side using JavaScript and jQuery.

这是我的code:

var videoID = 'kn8yzJITdvI';//not working 
//var videoID = 'p4kIwWHP8Vc';//working 
$.ajax({
    url: "https://gdata.youtube.com/feeds/api/videos/" + videoID + "?v=2&alt=json",
    dataType: "jsonp",
    success: function(data) {
        console.log(data)
          $("#result").text(data);
    },
    error: function(jqXHR, textStatus, errorThrown)
                    {
                        // Handle errors here
                        alert('ERRORS: ' + textStatus);

                    }
});

推荐答案

@hitesh,请删除数据类型:JSONP从Ajax请求。这样你会得到JSON字符串,如果视频ID可用,如果不可用,AJAX错误回调会被调用。我想在你的小提琴,它的工作。尝试这样的 -

@hitesh, Please remove the datatype:'jsonp' from the ajax request. This way you'll get json string if the video id is available and if its not available then the ajax error callback would be invoked. I tried on your fiddle and its working. Try like this-

//var videoID = 'kn8yzJITdvI';//not working 
var videoID = 'p4kIwWHP8Vc';//working 
$.ajax({
    url: "https://gdata.youtube.com/feeds/api/videos/" + videoID + "?v=2&alt=json",
    //dataType: "jsonp",
    success: function(data) {
        console.log(data)
          $("#result").text(data);
    },
    error: function(jqXHR, textStatus, errorThrown)
                    {
                        // Handle errors here
                        alert('ERRORS: ' + textStatus);
                    }
});

下面是另一个短期实现你所需要的解决方案 -

Here is another short implementation for the solution you need-

//var videoID = 'kn8yzJITdvI';//not working 
var videoID = 'p4kIwWHP8Vc';//working 

$.getJSON('http://gdata.youtube.com/feeds/api/videos/'+videoID+'?v=2&alt=jsonc',function(data,status,xhr){
    alert(data.data.title);
}).error(function() { alert("error"); });
