[英]Javascript works inline but not in a file
I am new to javascript and am assuming that the answer is simple and right under my nose, but I can't seem to find the proverbial dog that's going to bite me. 我是javascript的新手,并认为答案很简单,就在我的鼻子底下,但我似乎找不到能咬我的谚语的狗。
Anyway, this works inline: 无论如何,这可以内联:
<script language="javascript">
function foo(){
alert("BOO!")
}
</script>
<body onload=foo()>...
But if I do: 但是,如果我这样做:
<script type="text\javascript" scr="js/blah.js">
</script>
<body onload=foo()>
blah.js contains: blah.js包含:
function foo(){
alert("BOO!")
}
That doesn't work. 那不行
Why? 为什么?
正确的语法是:
<body onload="foo();">
The type is text/javascript
( /
instead of \\
), and the onload attribute in the body element should be onload="foo();"
类型为
text/javascript
( /
代替\\
),并且body元素中的onload属性应为onload="foo();"
. 。
Also, is your blah.js file stored inside a directory called js? 另外,您的blah.js文件是否存储在名为js的目录中?
Inside markup you can call JavaScript functions. 在标记内部,您可以调用JavaScript函数。 There is nothing wrong with it.
没有什么问题。 This creates a new anonymous function in the
DOM
tree and adds the value of the Event model as the function body. 这将在
DOM
树中创建一个新的匿名函数,并将Event模型的值添加为函数主体。
<script type="text\javascript" scr="js/blah.js"> </script>
should be 应该
<script type="text/javascript" src="js/blah.js"> </script> // / and src
should be 应该
<body onload="foo()"> // Markup attribute values should be passed inside quotes
所有属性值都必须以“开头”,并以“结尾”
