HTML正文中的Javascript函数，将无法正常工作 [英] Javascript function in html body, wont work
问题描述
< body onLoad =display（（））;}在我的文档中，我有一个onLoad函数， ）>
另外，我在文档的末尾添加了一个函数，它改变了一些CSS属性：
< script>
window.onload = foo（），bar（）;
< / script>
不知怎的，整件事情都行不通！我试图在文档的末尾添加所有函数，但我没有得到它，但它们不会触发！
p>它会调用这些函数，但它不会为<$ c $ c> window.onload 分配任何有用的内容，除非您的上一个函数恰好返回一个函数。您需要为 window.onload 分配一个函数，该函数将在窗口已准备就绪。
window.onload = function（）{
foo（）;
bar（）;
};
此外，由于您将脚本放在底部，因此您可能不需要 window.onload 。
< script>
foo（）;酒吧（）;
< / script>
< / body>
您还应该知道直接分配给 window.onload 会覆盖在< body onLoad = ...> 中分配的脚本，所以你不应该'两个都做。目前， bar（）; 的返回值正在清除调用 display（）; 的函数。
摆脱 window.onload 赋值可以解决这个问题。
In my document I have an onLoad function given like here in this example:
<body onLoad="display()">
In addition I added a function at the end of the document which changes some CSS properties:
<script>
window.onload = foo(), bar();
</script>
Somehow the whole thing doesn't work! I tried to add all functions at the end of the document but I don't get it, somehow they don't trigger!
That will invoke the functions, but it doesn't assign anything useful to window.onload unless your last function happens to return a function.
You need to assign a function to window.onload that will invoke your functions when the window is ready.
window.onload = function() {
foo();
bar();
};
Plus, since you're putting the script at the bottom, you probably don't need the window.onload.
<script>
foo(); bar();
</script>
</body>
You should also be aware that assigning directly to window.onload will overwrite the script assigned in the <body onLoad=...>, so you shouldn't do both. Currently, the return value of bar(); is wiping out the function that invokes display();.
Getting rid of the window.onload assignment will fix that.
