我无法在 canjs 网站上制作以下示例:http: //canjs.com/docs/can.Object.same.html#section_Examples
浏览器中加载的以下页面将出现错误:'Uncaught TypeError: Cannot read property 'same' of undefined'
<!DOCTYPE>
<html>
<head>
<title></title>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.js"></script>
<script src="http://canjs.com/release/latest/can.jquery.js"></script>
</head>
<body>
<script>
can.Object.same({ name: "Justin" }, { name: "JUSTIN" }) //-> false
// ignore the name property
can.Object.same({ name: "Brian" }, { name: "JUSTIN" }, { name: null }) //-> true
// ignore case
can.Object.same({ name: "Justin" }, { name: "JUSTIN" }, { name: "i" }) //-> true
// deep rule
can.Object.same({ person: { name: "Justin"} },
{ person: { name: "JUSTIN"} },
{ person: { name: "i"} }) //-> true
// supplied compare function
can.Object.same({ age: "Thirty" },
{ age: 30 },
{ age: function (a, b) {
if (a == "Thirty") {
a = 30
}
if (b == "Thirty") {
b = 30
}
return a === b;
}
}) //-> true
</script>
</body>
</html>
而且我还尝试使用requirejs来使用canjs:
var can = requirejs("can");
但它是同一件事,can.Object 仍然是“未定义”。我想使用 can.Object.same 因为要检查两个对象在值级别是否相等。我没有使用underscorejs,否则我可以使用_.isEqual。
====除了Sebastian的回答,如果使用requirejs,在require([...])的列表中添加“can/util/object”。====
