js正则表达式：替换一个单词不是后跟或后面没有单词

时间：2015-10-12 09:01:38

标签： javascript regex replace

我想替换“span”之外的“word”，并保留“span”内的另一个。到目前为止，当以下代码都跟随“mark＆gt;”时，以下代码有效然后是“跨度”。但我希望更进一步，遵循“标记＆gt;”或者后跟“span”，两个条件中的任何一个都应该导致替换动作。

var replaceString = "newWord";
var htmlString = "This <span style='color:red' title='mark'>normal word</span> need no change. This word is to be replaced. <span>Another word</span> need no change.";

var reg=new RegExp("(?!mark>)"+replaceString+"(?!<\/span>)","gi");
var bb=htmlString.replace(reg,replaceString);    
alert(bb) 

// Final result should be "This <span style='color:red' title='mark'>normal word</span> need no change. This newWord is to be replaced. <span>Another word</span> need no change.";

更新：使用标题作为标记。添加起始标记范围

更新：按照下面的建议，我正试图以anohter方式解决问题，请参阅此处：js regex: replace words not in a span tag

答案 0 :(得分：0)

您是否愿意使用其他span代码？ 通过在其中加入一个类名，您应该能够通过更改包含该类的每个span的内容来更改您需要更改的单词。

类似的东西：

This <span style='color:red' mark>word</span> need no change. This <span class='changeMe'>word</span> is to be replaced. Another word</span> need no change.

jQuery脚本正在进行

$('.changeMe').text("newWord")

如果您仍想使用Regexp，对于OR条件，您可能只需要执行两次：

var reg=new RegExp("(?!mark>)"+replaceString,"gi");
var bb=htmlString.replace(reg,replaceString);
reg=new RegExp(replaceString+"(?!<\/span>)","gi");
bb=htmlString.replace(reg,replaceString);

答案 1 :(得分：0)

您正在寻找负面预测（或Lookbehinds），但遗憾的是，JS并不支持。查看http://www.regular-expressions.info/javascript.html

您可以尝试以下正则表达式：

我宁愿建议使用JS来获取DOM元素并迭代替换文本（不确定它是否是单词，甚至是行话）。
