javascript - 在字符串中出现的所有链接上添加 target=_blank

Question

如何在函数内使用 javascript 为字符串中所有出现的 href 标记添加 target="_blank"？

例如:

输入字符串:

var input = 'this is a test string <a href="https://example.com" ui-link="https://example.com">example</a>, and this is another test string <a href="http://example2.com">example 2</a>.'

var output = convertString(input);

output should equal: 'this is a test string <a target="_blank" href="https://example.com" ui-link="https://example.com">example</a>, and this is another test string <a target="_blank" href="http://example2.com">example 2</a>.'

Answer 1

只需替换'

var input = 'this is a test string <a href="https://example.com" ui-link="https://example.com">example</a>, and this is another test string <a href="http://example2.com">example 2</a>';

function convertString(input){
  return input.split('<a').join('<a target="_blank"')
}

document.body.appendChild(document.createTextNode(convertString(input)))
