JavaScript-JSON ( 字串轉物件、物件轉字串)

利用JavaScript 實作JSON ( 字串轉物件、物件轉字串) 

function Json_onclick() {
	// A. 物件陣列,用中括號框住一組以 JSON 格式表現的物件
	var objArray = [
		{"firstName":"Derek", "lastName":"Jeter"}, 
		{"firstName":"Jeremy", "lastName":"Lin"}, 
		{"firstName":"Lionel", "lastName":"Messi"}
	];

    //JSON.stringify 將物件轉成Json字串
	debug.innerText = JSON.stringify(objArray);
	
	//JSON.parse  將Json字串 轉換成物件
	var objJsonArray =JSON.parse(JSON.stringify(objArray));
	    debug.innerText="";
    objJsonArray.forEach(function(obj){
        debug.innerText+=obj.firstName+"-"+obj.lastName;
        debug.innerHTML+="<br/>";
        
    })

}
