如何使用jquery或javascript从对象内部将当前对象作为JSON字符串返回？

I need a function to return the current instance as a json text, because I will send the values with an ajax request to server side script.

我需要一个函数将当前实例作为json文本返回，因为我将带有ajax请求的值发送到服务器端脚本。

I don't know where to use the "this" keyword in a jquery selector

我不知道在jquery选择器中何处使用“this”关键字

function Actor(){
 this.input=function(pname,ppassword){
  this.name=pname;
  this.password=ppassword;
 }
  //I need a function to return the current instance as a json text here
  //I will send the values with an ajax request to server side script with a function 
 }

I've found out that jquery doesn't support encoding as JSON and I need to use JSON2.js for serializing as JSON string.

我发现jquery不支持编码为JSON，我需要使用JSON2.js作为JSON字符串进行序列化。

New browsers have native JSON support so you can use JSON.stringify without including JSON2.js

新浏览器具有本机JSON支持，因此您可以在不包含JSON2.js的情况下使用JSON.stringify

You may need to be more specific in your question but if you need this in the input function to be a JSON string, you can use:

您可能需要在您的问题中更具体，但如果您在输入函数中需要这个是JSON字符串，您可以使用：

function Actor(){
    this.input=function(pname,ppassword){
       this.name=pname;
       this.password=ppassword;
       return JSON.stringify(this);//this will return pname and ppassword in json object string
     }
}
