从 javascript 字符串中删除特定 HTML 标签及其内容 [英] Remove specific HTML tag with its content from javascript string

问题描述

我有以下字符串变量，我想从字符串中删除所有 a 标签及其内容.

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>";

我已经检查过这个删除JavaScript 中从字符串开头到结尾的 HTML 内容组 问题的答案，但它适用于所有标签.

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.

谢谢

推荐答案

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:

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>
*/
