如何在JSON stringify中使用特殊字符？

I am trying to stringify my json code for sending it to MVC controller. But it does not work when data contains some special characters like greater than > or less than sign <.

我试图将我的json代码字符串化，以便将其发送到MVC控制器。但是当数据包含一些特殊字符（例如大于>或小于符号<）时，它不起作用。

Here is Sample code

这是示例代码

 function demo()
 {
     debugger
     var demo = [];
     demo.one = 'one';
     demo.two = '<just>'
     var treeBinding = JSON.stringify(demo);
     $.ajax({
         url: '/flow/demo',
         type: "GET",
         data: { dd: treeBinding },
         success: function (res) {

         },
         error: function (error) {
             alert(error)
         }
     });
 }

JSON.stringify returns a blank array in this case. Can anyone help me to get it worked?

在这种情况下，JSON.stringify返回一个空数组。任何人都可以帮我搞定吗？

First of all your declaration with array is incorrect.That is supposed to be an object but whatever case you need to check difference between object and array.However I assume that demo is an object with two key/properties which will be sent to server.

首先你的数组声明是不正确的。这应该是一个对象，但无论如何你需要检查对象和数组之间的区别。但是我假设demo是一个具有两个键/属性的对象，将被发送到服务器。

So declaration should look like this-

所以声明应该像这样 -

     var demo = {};
     demo.one = 'one';
     demo.two = '<just>';

Then you should use to escape -

然后你应该用来逃避 -

var treeBinding = encodeURIComponent(JSON.stringify(demo));

You can try something like this:

你可以尝试这样的事情：

function arrayToObjectString(arr) {
  var returnSrt = "{";
  for (var key in arr) {
    returnSrt += "\"" + key + "\" : \"" + arr[key] + "\"";
    returnSrt += ","
  }
  returnSrt = returnSrt.substring(0, returnSrt.length - 1) + "}";

  return returnSrt;
}

function main() {
  var demo = [];
  demo.one = 'one';
  demo.two = '<just>'

  console.log(JSON.stringify(demo))

  var resultStr = arrayToObjectString(demo);
  
  console.log(resultStr)
  console.log(JSON.parse(resultStr));
}

main();
