Remove specific HTML tag with its content from javascript string

Question

I have the following string variable and I want to remove all a tags with its content from the string.

var myString = "<table><tr><td>Some text ...<a href='#'>label...</a></td></tr></table>";
myString += "<table><tr><td>Some text ...<a href='#'>label...</a></td></tr></table>";
myString += "<table><tr><td>Some text ...<a href='#'>label...</a></td></tr></table>";

I have checked this Remove HTML content groups from start to end of string in JavaScript question's answers but it is for all tags.

Thank you

You should avoid parsing HTML using regex. Here is a way of removing all the <a> tags using DOM:

// your HTML text
var myString = '<table><tr><td>Some text ...<a href="#">label...</a></td></tr></table>';
myString += '<table><tr><td>Some text ...<a href="#">label...</a></td></tr></table>'
myString += '<table><tr><td>Some text ...<a href="#">label...</a></td></tr></table>'

// create a new dov container
var div = document.createElement('div');

// assing your HTML to div's innerHTML
div.innerHTML = myString;

// get all <a> elements from div
var elements = div.getElementsByTagName('a');

// remove all <a> elements
while (elements[0])
   elements[0].parentNode.removeChild(elements[0])

// get div's innerHTML into a new variable
var repl = div.innerHTML;

// display it
console.log(repl)

/*
<table><tbody><tr><td>Some text ...</td></tr></tbody></table>
<table><tbody><tr><td>Some text ...</td></tr></tbody></table>
<table><tbody><tr><td>Some text ...</td></tr></tbody></table>
*/

Here's the code. The regex /<a.*>.*?<\/a>/ig fits well for your data.

var myString = "<table><tr><td>Some text ...<a href='#'>label...</a></td></tr></table>";
myString += "<table><tr><td>Some text ...<a href='#'>label...</a></td></tr></table>";
myString += "<table><tr><td>Some text ...<a href='#'>label...</a></td></tr></table>";

console.log(myString);

var anchorTagsRemoved = myString.replace(/<a.*?>.*?<\/a>/ig,'');
console.log(anchorTagsRemoved);
