给定一个JSON字符串, 任务是将JSON字符串转换为JSON对象数组。此数组包含在JavaScript的帮助下从JSON字符串获得的JavaScript对象的值。有两种解决此问题的方法, 下面讨论：
方法1：首先使用将JSON字符串转换为JavaScript对象JSON.Parse()方法然后取出对象的值, 并使用将它们推入数组push()方法.
例子：
<!DOCTYPE HTML>
< html >
< head >

</ head >
< body style = "text-align:center;" >
< h1 style = "color:green;" >
lsbin
</ h1 >
< p id = "GFG_UP" ></ p >
< button onclick = "myGFG()" >
Click Here
</ button >
< p id = "GFG_DOWN" ></ p >
< script >
var up = document.getElementById("GFG_UP");
var JS_Obj =
'{"prop_1":"val_1", "prop_2":"val_2", "prop_3" : "val_3"}';
up.innerHTML = "JSON string - '" + JS_Obj + "'";
var down = document.getElementById("GFG_DOWN");
function myGFG() {
var obj = JSON.parse(JS_Obj);
var res = [];
for(var i in obj)
res.push(obj[i]);
down.innerHTML = "Array of values - ["
+ res + "]";
}
</ script >
</ body >
</ html >输出如下：
方法二：此方法也相同, 但使用的方法不同。使用将JSON字符串转换为JavaScript对象eval()方法然后取出对象的值, 并使用将其推入数组push()方法.

var down = document.getElementById("GFG_DOWN");
function myGFG() {
var obj = eval('(' + JS_Obj + ')');
var res = [];
for(var i in obj)
res.push(obj[i]);
down.innerHTML = "Array of values - ["
