You have not escaped properly. You make sure you do:
你没有正确逃脱。你确保你这样做：
var somejson = "{ \"key1\": \"val1\",\"key2\": \"value2\"}";
The easier way would be to just convert an existing object to a string using JSON.stringify(). Would recommend this as much as possible as there is very little chance of making a typo error.
更简单的方法是使用 将现有对象转换为字符串JSON.stringify()。会尽可能推荐这个，因为犯错的可能性很小。
var obj = {
key1: "val1",
key2: "value2"
};
var json = JSON.stringify(obj);

If you want the string, not the object (note the 'instead of ")
如果你想要字符串，而不是对象（注意'而不是"）
var somejson = '{ "key1": "val1", "key2": "value2" }';
If you want a string declared with multiple lines, not the object (newline is meaningful in Javascript)
如果你想要一个用多行声明的字符串，而不是对象（换行符在 Javascript 中是有意义的）
var somejson = '{'
+ '"key1": "val1",'
+ '"key2": "value2"'
+ '}';
If you want the object, not the string
如果你想要对象，而不是字符串
var somejson = { "key1": "val1", "key2": "value2" };
If you want a string generically
如果你一般想要一个字符串
var somejson = JSON.stringify(someobject);

I think you should use JSON.stringify function. See the answers here - Convert JS object to JSON string
我认为你应该使用 JSON.stringify 函数。在此处查看答案 -将 JS 对象转换为 JSON 字符串
var somejson = {
"key1": "val1",
"key2": "value2"
};
somjson = JSON.stringify(somejson);
