I recently wrote another project and used innerHTML. However, it is expected that onclick becomes invalid after innerHTML is called, because innerHTML is a button inserted in text format, therefore, The onclick event cannot be identified. We have to find another way out. We cannot implement it directly, but indirectly. The following is an example:Example 1:

OnClientClick is a client-side script, typically using JavaScript, running on the client, ie, and immediately after clicking.OnClick is a server-side event handler, using C # or vb.net, on the server side, which is IIS, click the button, execute the postback, and then run. If you want to call the OnClientClick before you call the OnClick event, you should return false in the OnClientClick event. If you do

In http://smartcloudblog.blogspot.com/2011/09/android-onclicklisteners-vs.html I mentioned four onclick implementation methods. I like the fourth one, that is, configuration in XML files, which is simple for everyone. So I tried textview and button to make a simple demo. It is found that it is easy to use when the button is used, but not when used as textview. Wh

Say a few words of complaint first.Although IE8 than the IE6, 7 have a lot of progress, but in the implementation of efficiency, compatibility still have many problems. A platform that is popular among developers is a good platform.Unfortunately, thanks to pirated XP opened China's computer market, ie as a bundle of software is still in China has a large use of people. Since the Chinese have buried their own pits, biting their teeth will also go down. The

In JavaScript, the execution sequence of mousedown, mouseup, and click is left to right. More importantly, once the mousedown event is activated, the next two events will be activated normally. We usually bind only one click event to a tag. In fact, events such as mousedown and mouseup are also called to trigger the click event, but their call cycle is very short, in addition, we didn't write the relevant functions to bind these two events, so we won't be aware of them. Now, if you want to regis

Excerpted from w3school:http://www.w3school.com.cn/htmldom/dom_events.aspOnMouseDown, onmouseup, and onclick events are the entire process of mouse clicks.First, when a mouse button is clicked, the OnMouseDown event is triggered, and then, when the mouse button is released, the OnMouseUp event is triggered and, finally, the o
