In this article, I will explain two more advanced event binding models: W3CAnd Microsoft. And because there is no really cross-browser, at least now, they are not in favor of using them.
Both W3C and Microsoft have developed their own event binding models to replace the traditional Netscape model. I'm not happy with Microsoft's model, but W3C is good except for a small flaw, but unfortunately few browsers

I. Differences between click events and touch events:

Socket. the io client is very elegant in event processing, which is similar to weboscket's limited javascript interface, but supports more custom events: varsocketio. connect ( amp; #39; http: // localhost: 9000/chat amp; #39;); socket. on ( amp; #39; conn.
The socket. io client is very elegant in event processing, wh

[Translator Press] Andy Li's article is the best and most thorough article I've ever seen about the SharePoint workflow architecture. By reading his article, I was clearly aware of the workings of SharePoint workflow and knew how to find a problem when I encountered a problem. Therefore, I hope to be helpful to the developers of workflow.This blog is made up of Andy Li contribution, he was SharePoint Developer Support Group of engineers who handle difficult issues.

In the preceding structure, when you click TR, the page is redirected to another page.
Function click () {window. Location. href = "XXX ";}
This avoids clicking the label and redirecting to another page. Onclick = "event. cancelbubble = true" cancel event processing.
Otherwise, when you click a, the system will jump to another page.

In the winform programming process, event processing is a very common programming activity, but I found that events that do not want to be executed frequently appear in my project.
Program But it is often executed. A common example is the selectedindexchanged event of ComboBox. This event occurs when a new item is sel

Event handler in SharePoint has two implementation methods: sps2003 implementation means (you need to enable "backward compatible event handler" in the SharePoint 3.0 Management Center) and sps2007 implementation means, for specific differences, please search for them online. Here we will talk about the precautions for deploying them.
The implementation method of sps2003 is generally to implement the ilist
In many languages, "events" are difficult to understand, but they are also a very important concept. The same is true for event processing in Javascript. It is precisely because of event processing that AJAX dragging will occur. This article will discuss the event

I will assume that you have some basic knowledge about delegation and multi-channel broadcast delegation. If you have not studied these important Microsoft. NET Framework features, you should do it now. For more information about these issues, see the Introduction to delegation in Ted pattison.
