Question

我正在尝试使用它删除字符串中的所有注释。

str = str.replace(/<!--(.*?)-->/g, "");

它在chrome中完美运行，但是当它在IE8中运行时，出乎意料的是，它不会删除文本的任何部分。

我注意到，当chrome放弃评论时，他们会变成这些行的东西：

&lt;!--[if !supportLists]--&gt;· &lt;!--[endif]--&gt;

以下是我的完整功能，基于This Link

function CleanWordHTML(str) {
    str = str.replace(/<o:p>\s*<\/o:p>/g, "");
    str = str.replace(/<o:p>.*?<\/o:p>/g, "&nbsp;");
    str = str.replace(/\s*mso-[^:]+:[^;"]+;?/gi, "");
    str = str.replace(/\s*MARGIN: 0cm 0cm 0pt\s*;/gi, "");
    str = str.replace(/\s*MARGIN: 0cm 0cm 0pt\s*"/gi, "\"");
    str = str.replace(/\s*TEXT-INDENT: 0cm\s*;/gi, "");
    str = str.replace(/\s*TEXT-INDENT: 0cm\s*"/gi, "\"");

    str = str.replace(/<\/H\d>/gi, '<br>'); //remove this to take out breaks where Heading tags were 
    str = str.replace(/<(U|I|STRIKE)>&nbsp;<\/\1>/g, '&nbsp;');
    str = str.replace(/<(B|b)>&nbsp;<\/\b|B>/g, '');
    str = str.replace(/<([^\s>]+)[^>]*>\s*<\/\1>/g, '');
    str = str.replace(/<([^\s>]+)[^>]*>\s*<\/\1>/g, '');
    str = str.replace(/<([^\s>]+)[^>]*>\s*<\/\1>/g, '');
    //comments
    str = str.replace(/<!--(.*?)-->/g, "");
    //spaces
    str = str.replace(/&nbsp;/g, '');
    //empty tags
    str = str.replace(/<[^\/>][^>]*><\/[^>]+>/g, '');


    //some RegEx code for the picky browsers
    var re = new RegExp("(<P)([^>]*>.*?)(<\/P>)", "gi");
    str = str.replace(re, "<div$2</div>");
    var re2 = new RegExp("(<font|<FONT)([^*>]*>.*?)(<\/FONT>|<\/font>)", "gi");
    str = str.replace(re2, "<div$2</div>");
    str = str.replace(/size|SIZE = ([\d]{1})/g, '');

    return str;
}

谢谢

Answer 1

作为评论中提到的apsillers，我可以使用它：

str = str.replace(/&lt;!--(.*?)--&gt;/g, "");

RegEx替换为ie8
