开始学习javascript,目前正在通过对象主题.
<!DOCTYPE html>
<html>
<body>
<h3>object prop access</h3>
<p id="demo"></p>
<p id="test"></p>
<script>
var foo = {unique_prop: 1}, bar = {unique_prop: 2}, object = {};
object[foo] = 'value1';
//console.log(object[bar]);
document.getElementById("demo").innerHTML = "Object property:"+object[bar];
document.getElementById("test").innerHTML = "Object property object[foo]:"+object[foo];
</script>
</body>
</html>
当我运行这个程序时,它会在单独的行中打印值" value1"," value1".我的问题是没有为" bar"定义属性名称" " object然后为什么object[bar]打印值" value1" - 分配给object[foo].
