[英]FBJS in facebook
I want to use javascript in my facebook application, but I don't know how to start with FBJS to use it. 我想在我的facebook应用程序中使用javascript,但我不知道如何从FBJS开始使用它。 Someone help me please! 有人帮帮我! just something like 就是这样的
<div onclick="greeting();">click me</div>
<script>
function greeting(){
alert("hello world");
}
</script>
This works for me: 这对我有用:
<script type="text/javascript">
function areyousure(description,id,opt) { var dialog = new Dialog(Dialog.DIALOG_POP).showChoice('Are you sure?','Are you sure you want to delete "' + description + '"? This action cannot be undone!','Yes','No');
dialog.onconfirm = function() {
document.setLocation("http://apps.facebook.com/myapp/delete.php?rec
ord=" + id + opt);
}
}
</script>
.
.
.
<a href="#" onclick="areyousure(arg1,arg2,arg3)" ><img src="http://mysite/images/delete.png" /></a>
A quick list of things that will get you, and what you should use instead: 快速列出将要获得的东西,以及您应该使用的内容:
alert() -> no equivalent
new Array() -> []
new Object() -> {}
The "Big 2" DOM changes, that broke a lot of my code "back when": “Big 2”DOM发生了变化,这使我的代码“退回时”:
innerHTML -> setInnerXHTML(), note that this is strict
id -> getId()
A list of all the DOM changes . 所有DOM更改的列表 。
Beware that FBJS is pretty poorly documented, so you'll have to play around with some things to get everything working. 请注意FBJS记录很差,所以你必须玩一些东西才能让一切正常。
As per this handy blog post , you can use Facebook's Dialog
object instead of alert
: 根据这篇方便的博客文章 ,您可以使用Facebook的Dialog
对象而不是alert
:
new Dialog().showMessage('Dialog', 'This is text');

function greeting(){
