JS 去除部分 HTML 代码

  • 772

如何在页面中找到代码并去除相同的代码片段？准确地说，这里是片段：

<span style="COLOR:GRAY; TEXT-DECORATION:NONE;">опубликовано:</span>

不仅不是块的内容，而是完全删除块。

  1. <span style="COLOR:GRAY; TEXT-DECORATION:NONE;">опубликовано:</span>


<script type="text/javascript">
var regex = /<span.+?="COLOR:GRAY.+<\/span>/ig;
document.body.innerHTML = document.body.innerHTML.replace(regex,"");
</script>

    <script>
  var regex = /(<span style="COLOR:GRAY; TEXT-DECORATION:NONE;">).*(<\/span>)/ig;

  //удалит все серые "Опубликовано"
  document.body.innerHTML = document.body.innerHTML.replace(regex, "");
</script>

  4.    function strip_tags( str ){  
        return str.replace(/<\/?[^>]+>/gi, '');
    }

    然后像这样使用

    strip_tags('<span style="COLOR:GRAY; TEXT-DECORATION:NONE;">опубликовано:</span>');
