在 HTML 中, 全局变量是 window 对象: 所有数据变量都属于 window 对象。

在 HTML 中, 全局变量是 window 对象: 所有数据变量都属于 window 对象。,第1张

准确说是浏览器窗口对象

我们的HTML+Javascript+css(前端代码)

是由浏览器内核程序进行解析渲染之后输出到浏览器的窗口中的,window

对象实际是当前窗口的实例

,你可以调用浏览器开放的API

来控制窗口的一切。

窗口的英文单词是

window

,可能因为这个原因,当年最早写JS

的人索性这个对象取名为

window

可以的. 比如你在html里面直接写上:

<script>

var ttt = 1

</script>

那么页面引用在此代码之下的都能知道这个变量,你所要做的就是把页面引用的js文件放在这行代码之后引用,别放在之前了.

把代码保存为html格式,上传到网页空间看看是不是你想要的!
