Google Apps脚本/Javascript搜索并用正则表达式替换不起作用 [英] Google Apps Script/Javascript search and replace with regex not working

问题描述

我知道那里有很多类似的问题和答案，但是我没有运气.

I know there are many similar questions and answers out there but I have had no luck.

我只是想在Google文档上运行一个正则表达式，并用大写字母替换它.我有一个有效的正则表达式，一个简单的字符串替换也可以，但是我无法使用任何形式的正则表达式.我在做什么错了?

I simply want to run a regex on a Google Doc and have it replace what it finds with Uppercase. I have a working regular expression, and a simple string replace works, but I can't get a regex of any kind to work. What am I doing wrong?

function searchAndReplace() {
var bodyElement = DocumentApp.getActiveDocument().getBody();
var regExp = new RegExp(/[\n][\n]([^\n]+)[\n][^\n|\s]/gim);
bodyElement.replaceText(regExp, '$1'.toUpperCase());
}

推荐答案

如

As shown in the replaceText documentation, it expects a string on both parameters. The first one will automatically generate a RegExp for you. Therefore you can use a regular expression, but due to this syntax limitation, you can not pass RegExp flags to it (in your example the gim).

此外，由于第二个参数也只接受字符串，因此您无法通知函数，这是您需要编写适当的toUpperCase的原因(即使使用内置的javascript，在您的示例中也是错误的) string.replace 函数).

Also, since the second parameter also only accepts a string, you can not inform a function, which is what you'd need to make a proper toUpperCase (which is wrong in your example even if using javascript built-in string.replace function).

从我刚进行的测试中，使用"$&"替换字符串模式或"$#"也不起作用.

And from tests I just made, replacement string patterns using "$&" or "$#" don't work either.

因此，要实现所需的功能，您必须自己实施搜索和替换操作(可能使用

So, to achieve what you're looking for you'll have to implement this search-and-replace yourself (possibly using findText to help on the "search" part).
