JavaScript - 转义双引号 [英] JavaScript - Escape double quotes

问题描述

如果 JSON 字符串如下，你如何转义双引号?

How do you escape double quotes if the JSON string is the following?

var str = "[{Company: "XYZ",Description: ""TEST""}]"

我想转义值 TEST 中的辅助双引号.

I want to escape the secondary double quotes in value TEST.

我尝试了以下方法，但不起作用.

I have tried the following, but it does not work.

var escapeStr = str.replace(/""/g,'"');

我错过了什么?

推荐答案

应该是:

var str='[{"Company": "XYZ","Description": "\"TEST\""}]';

首先，我将外引号改为单引号，这样它们就不会与内引号发生冲突.然后我在 TEST 周围最里面的引号之前加上反斜杠，以对它们进行转义.我转义了反斜杠，以便按字面意思处理.

First, I changed the outer quotes to single quotes, so they won't conflict with the inner quotes. Then I put backslash before the innermost quotes around TEST, to escape them. And I escaped the backslash so that it will be treated literally.

您可以使用 JSON 函数获得相同的结果:

You can get the same result with use of a JSON function:

var str=JSON.stringify({Company: "XYZ", Description: '"TEST"'});
