单击第二个按钮后运行HTML脚本的HTML按钮

Question

I am using HTML on a Raspberry Pi to control relays, currently I have a button for the On and another for the Off of the GPIO, I was wondering if there was a way I could press a single button once to call the On.php and press the same button a second time to call the Off.php without leaving the page.

Right now one button moves to the PHP script page which turns the GPIO On and then returns to the home page, the Off button does the same. This is a bad method but it worked.

Answer 1

Seting a global variable to calculate the times of your clicking (flag==0). Then writing something to define which functions you want to use.

Answer 2

我为输入使用了一个复选框，单击该复选框时会调用一个函数，然后检查是否被勾选，然后代码使用变量来确定GPIO引脚应处于什么状态。
