javascript - 如何在页面中将其添加为html

Question

这是一个在 ajax 调用中获取的数据。它应该是html。如何将其作为 html 添加到 div 中？我认为字符以安全格式返回。有没有办法通过 javascript 或 php 打印它？

Answer 1

字符以转义的 unicode 格式返回。您可以使用此函数将其编码为 UTF8:

function encode_utf8( s )
{
  return unescape( encodeURIComponent( s ) );
}

例如:

encode_utf8( '\u003Cscript type=\u0022text\/javascript\u0022\u003E' ); -> '<script type="text/javascript">'
