使用JQuery在现有文本周围插入锚标记

Question

I have some HTML on a page that reads as follows:

<h3 class="ms-standardheader"><a name="SPBookmark_History"></a>History</h3>

I am running some javascript in the page READY where I am creating a dynamic hyperlink and I would like that to be inserted so that when the page renders the final result is:

    <h3 class="ms-standardheader"><a name="SPBookmark_History"></a><a href="https://thissite.com/newurl" target="_blank"> History</a></h3>

The class name of the H3 exists on multiple page elements. The Name of the anchor tag, SPBookmark_History, is unique.

How can I accomplish this using JQuery or straight javascript?

Thank you

Answer 1

Just follow below code:

$(document).ready(function(){
  var link = $('a[name=SPBookmark_History]');
  link.attr('href','https://thissite.com/newurl');
  link.attr('target','_blank');
});

You can use:

• Attribute Equals Selector [name=”value”] : in order to select the element because SPBookmark_History is unique
• .closest( selector ) : to get the parent h3 element.
• .contents() : Get the children of each element in the set of matched elements, including text and comment nodes.
• filter-function : in order to get only the text after the link
• .wrap() : Wrap an HTML structure around each element in the set of matched elements.

The code:

 $('a[name="SPBookmark_History"]').closest('h3.ms-standardheader') .contents(). filter(function (idx, ele) { return ele.nodeType == Node.TEXT_NODE }) .wrap($('<a/>', {href: "https://thissite.com/newurl", target: "_blank"})); console.log('Result is: ' + document.getElementsByClassName('ms-standardheader')[0].outerHTML);
