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

问题描述

如果JSON字符串为以下字符串，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""}]"

我想对值 TEST 中的辅助双引号进行转义.

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

我尝试了以下方法，但是它不起作用.

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

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

我想念什么?

推荐答案

应为:

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

首先，我将外部引号更改为单引号，因此它们不会与内部引号冲突.然后，我将反斜杠放在TEST的最内层引号之前，以使其转义.而且我避开了反斜杠，以便将其按字面意义处理.

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.

使用JSON函数可以获得相同的结果

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

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