If a button can be clicked more than once in a short period of time, it may be malicious clicks of the user, in order to prevent this situation, you can set a certain time to click only once, other times prohibit the click button. The code is as follows: Copy Code code as follows:

The basic implementation is in the foreground page = users download every click, download the number of times add 1, and download the corresponding files to the local. The required HTML code The content in the HTML code, then need to use Ajax from the background to get in the display. The jquery code you need $.ajax ({ type: ' Get ', URL: ' filelist.php ', dataType: ' json ', cache:false, before

Iscroll actually intercepts the Touchstart and Touchend events when clicking on the browser. In Touchend, use JS to trigger the element's OnClick event (_end this function). In practice, the touchend is executed first and then the correlation function of the onclick is executed. This creates a two-click trigger for a headache. There are a lot of code on the Internet to solve the "Iscroll Click event" Click a trigger two times, I also follow the steps

Not a few years of study, poor ability to express, grassroots do not blame the station 1 years to be K8 times, not jian a few money, the end of the brain, money, harm is also sad!!!

Write a program, open 3 threads, the IDs of the 3 threads are a, B, C, each thread prints its own ID on the screen 10 times, the output must be displayed in the order of ABC, such as: Abcabc .... recursion in turn. #include #include The results are as follows:

Now that there is an array that is known to be more than half the number of occurrences, use an O (n) complexity algorithm to find this number. Analysis: Set number A appears more than half times. Each time you delete two different numbers, the number a appears more than half in the remaining number. By repeating this process, the final result is obtained. This topic is the same as the beauty of programming in the search for water kings. [CPP] View pl

Topic links Test instructions: Your task is to help J out of a maze of fires spreading. J can move up or down in four directions per minute, and all the burning squares will spread around. There are some obstacles in the maze, J and fire can not enter. When J went to the boundary lattice of a maze, we thought he had gone out of the maze. Idea: This is a problem above the white, in fact, as long as each lattice what time on fire to deal with it. Two times
