Question

Hello Guys我正在尝试使用Jquery动态绑定内容。我在stackoverflow网站上进行了很多讨论例如How to insert metatag without using jquery append?

以下是我尝试过的代码。我不知道我做错了什么。任何帮助都会受到启发。

<head>
    <meta property="og:description" content="sdgds"/>
    <meta property="og:title" content="sfsfds"/>
    <meta property='og:image' content="http://i1.ytimg.com/vi/v9ao-fGMVz8/maxresdefault.jpg" />
    <meta property='og:video' content="http://abcd.azurewebsites.net/api/Video/?video_id=1" />
     <meta property="og:video:type" content="application/x-shockwave-flash" />
     <meta property="og:video:width" content="1920" />
     <meta property="og:video:height" content="1080" />

    <script src="http://code.jquery.com/jquery-1.10.1.min.js"></script>
    <script>
    $(document).ready(function() {
            var first = getUrlVars()["id"];
            $.ajax({
            type: "Get",
            url: 'http://abcd.azurewebsites.net/api/Video/?video_id=1',
            success: function (data) {  
                alert("Hello");
                var tv_main_channel = $('#tv_main_channel');
                data="http://abcd.azurewebsites.net/Content/movie.mp4";
                tv_main_channel.attr("src", data);
                var video_block = $('#video');
                video_block.load();

                $('meta[name=og\\:description]').attr('content', "This is des");

            },
            error: function (XMLHttpRequest, textStatus, errorThrown) {
            console.log(JSON.stringify(XMLHttpRequest));
            }
            });
        });

    function getUrlVars()
    {
        var vars = [], hash;
        var hashes = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&');
        for(var i = 0; i < hashes.length; i++)
        {
        hash = hashes[i].split('=');
        vars.push(hash[0]);
        vars[hash[0]] = hash[1];
        }
        return vars;
    }

    </script>




</head>

您使用的jquery版本不适合这样做。使用较新的版本。
