在队列的头部添加事件 [英] Add event in the head of the queue
问题描述
- 如何在队列的头部添加一个特定事件类型的事件?
你正在使用jquery框架吗?我正在使用extjs,我找到一个你可以使用或复制的课程
让我们看看 http://extjs.com/deploy/dev/docs/ Ext> EventManager> removeAll()
< blockquote>
removeAll(String / HTMLElement el):
void从
元素中删除所有事件处理程序。通常,您将直接在元素上使用
Ext.Element.removeAllListeners
,以支持
调用此版本。参数:el:
String / HTMLElement要从中删除事件的id或html
元素
返回:void
我认为您可以将标签 body
设置为HTMLElement以关闭所有事件。 (未测试对不起)
下载此处 http ://extjs.com/products/extjs/build/ 选择jquery适配器,如果你使用jquery> extcore将足够(它包含EventManager.js)。
另一方面,像crescentfresh(answer n°4),我将此示例代码应用于所有节点事件:
var nodes = document.getElementsByTagName('*'); //收集你的节点
for(var i = 0; i< nodes.length; i ++){
var node = nodes [i];
Ext.EventManager.removeAll(node);
}
}
如果您在使用extjs时遇到问题,请通知我如果我的回答是有用的,可以帮助我,并为我投票。
I have already defined onclick event. I want to add additional call back function, that will be invoked BEFORE already defined callback.
- How to add an event in the head of the queue for concrete event type?
Are you working with jquery framework ? I'm currently working with extjs and i found a class you can use or copy
Lets see on http://extjs.com/deploy/dev/docs/ Ext > EventManager > removeAll()
removeAll( String/HTMLElement el ) : void Removes all event handers from an element. Typically you will use Ext.Element.removeAllListeners directly on an Element in favor of calling this version. Parameters: el : String/HTMLElement The id or html element from which to remove the event Returns: void
I think You can set the tag body
as HTMLElement to shut down all events. (not tested sorry)
Download here http://extjs.com/products/extjs/build/ > select jquery adapter if you are working with jquery > extcore will suffice (it contain EventManager.js ).
On the other way, like crescentfresh (answer n°4), i made this sample code to apply to all node events :
var nodes = document.getElementsByTagName('*'); // collect your nodes however
for(var i=0; i < nodes.length; i++) {
var node = nodes[i];
Ext.EventManager.removeAll(node);
}
}
Please let me know if you have trouble using extjs i can help, and vote for me if my answer is useful.
