Changing meta-tags dynamic with jQuery
提问by OptimusCrime
These are my meta-tags:
这些是我的元标签:
<meta property="og:image" content="assets/css/gfx/skold.png"/>
<meta property="og:title" content="Den historie hjemmesiden for Norges Golfforbund"/>
<meta property="og:description" content="Her finner du alle de historie tingene som har skjedd i Norges golfhistorie gjennom tidene" />
<meta property="og:url" content="http://###"/>
<meta property="og:site_name" content="Norges Golfklubb"/>
<meta property="og:type" content="sport"/>
And I am trying to change them dynamic with the following code:
我正在尝试使用以下代码动态更改它们:
$("meta[property=og:title]").attr("content", result.title);
But I am keep getting Syntax error, unrecognized expression: [property=og:title] in Firebug.
但我不断收到语法错误,无法识别的表达式:[property=og:title] 在 Firebug 中。
Using the latest version of jQuery. Does anyone know what I am doing wrong?

I think you should escape :
look at the documentation
我认为你应该逃避:
看文档
$("meta[property='og\:title']").attr("content", result.title);
回答by Curtis
$("meta[name='og:title']").attr('content', 'my new title');
Using "property=" does not work in Chrome
在 Chrome 中使用“property=”不起作用

Make sure your quotes are like this:
确保你的报价是这样的:
$('meta[property="og:description"]').attr('content',"$modified_desc" );
回答by Frankey
You could give each meta element an ID or Class.
你可以给每个元元素一个 ID 或类。
$('#metaelement').attr('content', 'my new meta description');
