This time I bring to you what are the precautions. The following is a practical case, let’s take a look.
After the countdown time is up, click the recovery button, which is often used to read the agreement:
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>阅读协议倒计时</title> <script> var tim=9; function aaa(){ var btnn=document.getElementById("btn"); if(tim<=0) { btnn.value="注册"; btnn.disabled=""; } else { btnn.value="请仔细阅读,还剩" +tim+"秒"; tim--; } } setInterval("aaa()",1000); </script> </head> <body> <textarea style="width: 500px;height: 300px;"> </textarea> <input type="button" id="btn" value="请仔细阅读,还剩10秒" disabled="disabled" /> </body> </html>
