JSON parse double quotes in string literal
提问by brewsky
I am having problem parsing quotes in string literal.
我在解析字符串文字中的引号时遇到问题。
var lit = '{"foo":"test \"1\"","bar":"test 2"}';
In console, this gives an error 'Uncaught exception'. I am expecting:
在控制台中，这会给出错误“未捕获的异常”。我期待：
Object {foo: "test "1"", bar: "test 2"}
Here is my fiddle https://jsfiddle.net/bruceradtke/kor8amm5/4/
这是我的小提琴https://jsfiddle.net/bruceradtke/kor8amm5/4/
It works ok if I assign stringify result to variable and then parse that variable. But not if I use string literal as above.
如果我将 stringify 结果分配给变量然后解析该变量，它就可以正常工作。但如果我像上面那样使用字符串文字，则不会。
Thanks.
谢谢。
My code:
我的代码：
var myobject = {};
myobject.foo = "test \"1\"";
myobject.bar = "test 2";
var sresult = JSON.stringify(myobject);
console.log('stringify=' + sresult);
// OK
var thaw = JSON.parse(sresult);
console.log( thaw);
var lit = '{"foo":"test \"1\"","bar":"test 2"}';
console.log(lit);
// Broken
var thaw2 = JSON.parse(lit);

Remember that you are escaping two string literals: one for declaring the property and one for declaring the variable (lit). So you need to escape your escape character: "test \\"1\\""
请记住，您正在转义两个字符串文字：一个用于声明属性，另一个用于声明变量 ( lit)。所以你需要转义你的转义字符："test \\"1\\""
var lit = '{"foo":"test \"1\"","bar":"test 2"}';
console.log(lit);
var thaw2 = JSON.parse(lit);
