如何添加带有特殊字符的字符串作为json键? [英] how to add string with special character as json key?

问题描述

我想在JSON中添加带有特殊字符的字符串作为KEY.例如" Sam @ 123 "
这是我正在尝试的代码.

I want to add string with special character in JSON as KEY.For example "Sam@123"
Here is the code, that I am trying.

<script type="text/javascript">

var jsonObj={"sam":1,"rudolph":1,"js":1," ":12};
var key="samw@123";
alert("Add it.")
// Adding the key with Special Character in JSON
eval("jsonObj."+key+"=11")
alert("Added successfully.")

for(var i=0; i< Object.keys(jsonObj).length; i++){
alert("KEY#"+Object.keys(jsonObj)[i]);
}

</script>

我在第6行"eval......"上遇到以下错误.

I am getting following error at line 6 "eval......".

未捕获到的SyntaxError:意外令牌ILLEGAL

Uncaught SyntaxError: Unexpected token ILLEGAL

还有其他方法可以在Json中添加特殊字符作为KEY吗?

Is there any other way to add special character in Json as KEY?

我也无法添加

var key="samw-123";

为此，我说错了

未捕获的ReferenceError:分配中的左侧无效

Uncaught ReferenceError: Invalid left-hand side in assignment

推荐答案

使用以下语法应该可以正常工作:

Should work fine using such syntax instead:

eval("jsonObj['" + key + "'] = 11");

实际上，甚至不需要eval:

jsonObj[key] = 11;
