How to stop settimeout in jquery
The clearTimeout() method can cancel the scheduled operation set by the setTimeout() method.
Cancel the timeout set by the setTimeout() method
The parameter of the clearTimeout() method must be the ID value returned by setTimeout().
Note: To use the clearTimeout() method, use global variables when creating and executing scheduled operations:
myVar = setTimeout("javascript function", milliseconds);If the method has not been executed, we can use clearTimeout() to prevent it.
clearTimeout(id_of_settimeout)
id_of_setinterval is the return value obtained when calling the setTimeout() function. Using the return identifier as a parameter can cancel the scheduled execution operation set by the setTimeout().
The example is as follows:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>123</title>
</head>
<body>
<p>点击按钮，等待 3 秒后弹出 "Hello" 。</p>
<p>点击第二个按钮来阻止弹出函数 myFunction 的执行。 (你必须在 3 秒前点击)</p>
<button onclick="myFunction()">先点我</button>
<button onclick="myStopFunction()">阻止弹出</button>
<script>
var myVar;
function myFunction() {
myVar = setTimeout(function(){ alert("Hello") }, 3000);
}
function myStopFunction() {
clearTimeout(myVar);
}
</script>
</body>
</html>Output result:
If you only click the first button, three seconds A pop-up window will appear:
If the second button is clicked within three seconds after clicking the first button, the pop-up window will not appear.
