任何人都可以帮我处理这个脚本，当html代码粘贴到textarea时应该替换标签？由于未知原因，只更换了一些标签，但大约1/4或1/5的标签不会被替换。

我在控制台日志中得到了这个：
editor.on( 'paste', function( evt ) {
for (k in hArray)
{
console.log(k + ': ' +evt.data.dataValue
.match( hArray[k] ));
evt.data.dataValue = evt.data.dataValue
.replace( hArray[k], k );
}
所以真的没有比赛。如何修复脚本以替换短字符串的所有指定标记和字符串？

'@im': /(img)/gi, 控制台清楚地说明找不到img标记。但是源文本中有很多图像。最后一个索引："@im: null" add.php:836没有被替换，但由于未知原因它不在日志中。
编辑： 要减少代码，只需缩短模式数组： var editor = CKEDITOR.instances [＆＃39; edit＆＃39;];
'@im': /;"><img/gi在控制台中：生成结果：＆＃34; @im：img，img，img，img，img，img，img＆＃34;并成功替换了img字符串。但是使用这个：
var hArray={ '@im': /img/gi }
不会产生任何结果。看起来有一些语法错误或某些行阻止匹配和.replace完成工作。
编辑： 我发现这个单个html文件有效：
'@im': /;"><img/gi <body>
<script>
var str = '<img name=text>';
str = str.replace( /<img /gi ,'***');
// console.log( str );
alert(str);
</script>
</body>
无法打印str。这也可以在我的脚本中使用，但是如果我使用hArray：console.log( str );那么这样做也没有改变。
答案 0 :(得分：3)
正则表达式不是解析HTML的正确工具。在RegEx match open tags except XHTML self-contained tags有一个很好的答案，虽然它有点自命不凡，但确实说明了这一点。除非这是一次性工作，不需要维护或仅限于单个输入，而且不会发生重大变化，否则Regex不是解析HTML的正确工具。
那么什么是正确的工具？嗯，HTML是XML的一种特殊形式，因此从理论上讲，您可以使用XML解析器。但是，对于javascript来说，还有更好的方法。你看，Javascript旨在与HTML一起工作。因此，您可以将HTML输入视为HTML页面，并像通常那样处理它：
editor.on( 'paste', function( evt ) {
var el = document.createElement('html');
el.innerHTML = evt.data.datavalue
//Now do whatever editing you have to do to replace in here using the normal DOM tools.
});
答案 1 :(得分：0)
变量evt.data.dataValue的内容包含已翻译的标签：
alert(evt.data.dataValue);
