从javascript字符串中删除包含其内容的特定HTML标记

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

我有以下字符串变量,我想从字符串中删除所有带有内容的标记。

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.

我已经检查了这个在JavaScript问题的答案中从字符串的开头到结尾删除HTML内容组,但它适用于所有标签。

Thank you

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

您应该避免使用正则表达式解析HTML。这是一种使用DOM删除所有标签的方法:

// 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.

这是代码。正则表达式/ .*?<\/a>/ig非常适合您的数据。 *>

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);

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>";

el = document.createElement('div');
el.innerHTML = myString;

var output = document.getElementById('output');
el.querySelectorAll('a').forEach(function(item, index){
	item.parentNode.removeChild(item);
})
output.innerText = el.innerHTML;

<h3>Output:</h3>
<pre id='output'></pre>
