给定一个JSON字符串，任务是将JSON字符串转换为JSON对象数组。
这个数组包含在JavaScript的帮助下从JSON字符串中获得的JavaScript对象的值。解决这一问题的方法有两种:
方法一
首先使用JSON. parse()方法将JSON字符串转换为JavaScript对象，然后使用push()方法取出对象的值并将它们推入数组。

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> 方法二
此方法也是相似的，只是使用不同的方法。使用eval()方法将JSON字符串转换为JavaScript对象，然后取出对象的值并使用push()方法将它们推到数组中。
