jQuery在新窗口中打开链接无法正常工作

问题描述：

我有一个动态导航，需要在新窗口中打开一个链接。

I have a dynamic navigation and need to open one link in a new window.

因此我使用jQuery来帮助，但下面的代码看起来不像工作：

As such I am using jQuery to help, but the following code does not seem to work:

<script type="text/javascript">
 $('a[href="http://globalhealth-dev.oit.duke.edu/education/global-health-courses"]').attr("target", "_blank");
</script>

为自己尝试： http://globalhealth-dev.oit.duke.edu/education/ 然后点击教育下的全球健康课程链接。

To try it for yourself: http://globalhealth-dev.oit.duke.edu/education/ then click on the Global Health Courses link under Education.

我希望得到一些帮助，让它正常工作。

I would appreciate some help getting this to work properly.

谢谢。

答

脚本的选择部分是错误的，即应该与元素中的href匹配的href。试试这个：
$（'a [href =/ education / global-health-courses]'）。attr（target，_ blank）;

The selection part of your script is wrong, namely the href that should match the href in the element. Try with this: $('a[href="/education/global-health-courses"]').attr("target", "_blank");

另请注意，建议不要使用href选择该链接，因为它比仅使用元素中的id然后使用$（a #myid）。

Also note that it is not recommended to select that link using href as it is slower than just using a id in the element and then using $("a#myid").

还要小心只在文档加载时调用它：

Also be careful to call this only when the document is done loading:

 <script type="text/javascript">
    $(document).ready(function() {
        $('a[href="/education/global-health-courses"]').attr("target", "_blank");    
    });
</script>
