在使用jQuery替换时，是否可以忽略字符串中的HTML？ [英] Can you ignore HTML in a string while doing a Replace with jQuery?

问题描述

可能重复：

替换字符串中的单词，但忽略HTML

调用Replace时是否可以忽略HTML元素？

Is it possible to ignore the HTML elements when calling Replace?

示例代码：

$myText.replace(new RegExp( $searchString, 'gi' ), 
    '<span class="highlight">'+ $searchString + '</span>');

$ myText 是一大串HTML例如：

$myText is a large string of HTML e.g.:

var $myText = 
    "<p>Lorem Ipsum is simply dummy text of the printing and typesetting " +
    "industry. Lorem Ipsum has been the industry's standard dummy text " +
    "ever since the 1500s, <img src="something">when an unknown printer " +
    "took a galley of type and scrambled it to make a type specimen book. " +
    "It has survived not only five centuries, " +
    "<a href="#" title="Lorem">but</a> also the leap into electronic " +
    "typesetting, remaining essentially unchanged. It was popularised in " +
    "the 1960s with the release of Letraset sheets containing Lorem Ipsum " +
    "passages, and more recently with desktop publishing software like " +
    "Aldus PageMaker including versions of Lorem Ipsum.</p>"

$ searchString 等于用户类型为文本输入框。

$searchString is equal to whatever a user types into an text input box.

如果是，在给定上述示例代码的情况下我该怎么做？

If yes, how would I do it given the above sample code?

RegEx您正在寻找的模式类似于以下内容：

The RegEx pattern you are looking for would be something similar to the following:

"(?<!<[^>]*)Jon Doe(?<![^>]*<)"

基本上，你正在搜索并替换括号以外的任何东西<>。

Basically, you're doing a search and replace on anything that lives outside brackets <>.

JavaScript：

JavaScript:

phrase = phrase.replace(/"(?<!<[^>]*)Jon Doe(?<![^>]*<)" /i, "is not");
