pdx event source

Yesterday, someone in the group asked an event source location problem, the simple description is like this. On a page that isn't written by yourself, how can you quickly locate the event code he's bound to? (The page is in jquery)This question, say difficult, say simple also not so simple, in case of use is commissioned and so will trouble point. There's an

Overview have been trying to write an article on the Android event distribution mechanism, but has not written, these two days is just the weekend, have time, think about writing a bar, or always only stay at the level of use but not understand its internal mechanism. I use 4.4 source code, open look, very complex, especially how the event is distributed from th

In the previous article "uiautomator source code analysis-uiautomatorbridge framework", we described uiautomatorbridge and its related classes. Next we will try to concatenate these classes based on two instances, I am going to use the following two representative instances: Injection event Get control In this article, we will analyze the presshome method of uidevice to analyze how uiautom

Native side events distributed to the Java side and the framework of the distribution of events to the UI, the process to see the source code, here is not redundant,The working class diagram of the native side distribution event is as follows: The class diagram for the framework side distribution event is as follows: Starting with activity.dispatchtouchevent, the

Package of 6.1 Event Browser event compatibility is a troubling issue. IE's event is under the Global window, and Mozilla's event is the incident source parameter passed into the callback function. There are also many ways to handle events. jquery provides a package of

Android View event distribution mechanism source code analysis (I) I have always wanted to write an article about the event distribution mechanism. Whatever the case, I have to study the source code of event distribution and write my own experiences ~ First, let's write a si

, handlenonezeroinput){Expect_eq (4, M_foo.calc (12,16));} Test_f (foocalctest, handlenonezeroinput_error){Expect_eq (5, M_foo.calc (12,16));} V. Summary The three event mechanisms provided by gtest are very simple and flexible. At the same time, by inheriting the test class and using the test_f macro, we can share some common methods and resources between cases. This makes our cases more concise and clear. Series links: 1. Go to Google's open-

has been to view the event distribution mechanism is not very clear, in the project development also encountered, in the online also found some problem-solving methods, but its principle is not very understanding, now resigned to have time, today write a view of the event distribution, combined with the Android source code together to learn, if not speaking, Go t

Android event distribution mechanism source code analysis I am a little touched by the fact that I have been using android for some time.

The previous chapter, which is probably an overview, describes the purpose and use of event binding, knowing what kind of process it is inside, from which function to which function. Whether jquery's source code is simple or complex, it is certain that jquery is committed to solving browser compatibility issues and ultimately serving users. Some legacy issues When we first introduced Bind, delegate and thei

. Finally, the default behavior is triggered with the native Event trigger function (Click,focus). and setting a jQuery.event.triggered flag to flag is to trigger the default behavior and avoid triggering the event again.Finally, the source code.Triggerfunction(Event, data, Elem, onlyhandlers) {//events can be
