Question

我有一个脚本来获取在meta标签中使用的基本网址，但它似乎没有工作......

第一：我的脑袋看起来像这样......

<head>
    <meta charset='utf-8'> 
    <title>****</title> 
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <meta name="description" content="****" />
    <meta name="keywords" content="****" />
    <!--FACEBOOK OPEN GRAPH META TAGS - THIS IS WHAT GETS POSTED-->
    <meta property="og:site_name" content="*****"/>
    <meta property="og:title" content="<!-- TMPL_VAR street_no --> <!-- TMPL_VAR street --> <!-- TMPL_VAR city -->, <!-- TMPL_VAR state --> <!-- TMPL_VAR zip --> | $<!-- TMPL_VAR NAME=price -->" />
    <meta property="og:description" content="Listing found at..." />
    <meta property="og:type" content="website" />
    <meta property="og:url" />
    <meta property="og:image" content="http://sandbox.dev.activemls.com/property/photo/<!-- TMPL_VAR listing_id -->/1" />
    <!--END FACEBOOK OPEN GRAPH-->
    <link rel="stylesheet" type="text/css" href="/static/bootstrap/css/bootstrap.css" />
    <link rel="stylesheet" type="text/css" href="/static/css/shell.css" />
    <link rel="shortcut icon" href="/static/images/favicon.png" type="image/x-icon" />
    <script src="http://maps.google.com/maps/api/js?sensor=false&amp;language=en" type="text/javascript"></script>
    <script src="/static/js/jquery-1.9.1.js "></script>
    <script src="/static/bootstrap/js/bootstrap.min.js"></script>
    <script type="text/javascript" src="/static/js/gmap3.js"></script>
    <script type="text/javascript" src="/static/js/shell.js"></script>
    <script>alert(base)</script>
</head>

我的剧本是......

function baseURL () {
    base = window.location.protocol+"//"+window.location.host+"/";
    return base; 
};

$("meta[property='og:url']").attr("content", base+"/property/detail/<!-- TMPL_VAR mls_number -->");

当我加载页面时，og：url仍为空白...

当前修订

来自shell.js的

：

/*******************************/
/*  GET BASE URL
/*******************************/
function baseURL () {
    base = window.location.protocol+"//"+window.location.host+"/";
    $("meta[property='og:url']").attr('content', base+'/property/detail/<!-- TMPL_VAR mls_number -->')
    return base; 
};baseURL();
console.log(base);
