Javascript Escape Double Quotes
提问by MDuB
How do you escape double quotes if the JSON string is this:
如果 JSON 字符串是这样的，你如何转义双引号：
var str = "[{Company: "XYZ",Description: ""TEST""}]"
I want to escape the secondary double quotes in value TEST.
我想转义值 TEST 中的辅助双引号。
I have tried this but it does not work.
我试过这个，但它不起作用。
var escapeStr = str.replace(/""/g,'\"');
What am I missing?
我错过了什么？

It should be:
它应该是：
var str='[{"Company": "XYZ","Description": "\"TEST\""}]';
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.
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。然后我在最里面的引号之前加上反斜杠TEST，以逃避它们。我避开了反斜杠，以便按字面意思处理。
You can get the same result with use of a JSON function:
使用 JSON 函数可以获得相同的结果：
var str=JSON.stringify({Company: "XYZ", Description: '"TEST"'});

Here inner Quote escaped and entire string taken in single Quote.
这里内部报价转义，整个字符串采用单引号。
var str = '[{ "Company": "XYZ", "Description": "\"TEST\""}]';
