<script type="text/javascript">
//倒计时30秒
var i = 30;
function remainTime() {
if (i > 0) {
document.getElementById("endtime").innerHTML = i--;
setTimeout("remainTime()", 1000);
}
if (i == 0) {
$("p").text("活动开始");
$("p").css("background-color", "yellow");
//倒计时结束，按钮状态改为可用
document.getElementById("btn").disabled = false;
}
}
remainTime();
//点击按钮触发的方法
function func() {
alert("恭喜你抢到一个月饼");
}
</script>

<script type="text/javascript">
var button = document.getElementById("btn");
//每秒执行一次，若按钮状态为可用，进行点击
setInterval(function() {
if (button.disabled == false) {
button.click();
}
},
1000);
</script>
##Modify setInterval(function(){},millisec) The millisec (in milliseconds) can control the click frequency.
This is just a simple js code that does not implement automatic verification of the verification code.

Automount drives on Linux
Mar 20, 2024 am 11:30 AM
If you are using a Linux operating system and want the system to automatically mount the drive on boot, you can do this by adding the device's unique identifier (UID) and mount point path to the fstab configuration file. fstab is a file system table file located in the /etc directory. It contains information about the file systems that need to be mounted when the system starts. By editing the fstab file, you can ensure that the required drives are loaded correctly every time the system starts, thus ensuring stable system operation. Automatically mounting drivers can be conveniently used in a variety of situations. For example, I plan to back up my system to an external storage device. To achieve automation, ensure that the device remains connected to the system, even at startup. Likewise, many applications will directly

Linux Tips: Cancel automatic indentation when pasting in vim
Mar 07, 2024 am 08:30 AM
Preface: vim is a powerful text editing tool, which is very popular on Linux. Recently, I encountered a strange problem when using vim on another server: when I copied and pasted a locally written script into a blank file on the server, automatic indentation occurred. To use a simple example, the script I wrote locally is as follows: aaabbbcccddd. When I copy the above content and paste it into a blank file on the server, what I get is: aabbbcccddd. Obviously, this is what vim does automatically for us. Format indentation. However, this automatic is a bit unintelligent. Record the solution here. Solution: Set the .vimrc configuration file in our home directory, new
