在JavaScript的SetInterval（）函数中传递参数

Posted 2021-02-23

You may perform this work with two ways: pass it directly like described in sample #1 or use an anonymous function like its shown in sample #2.

<script type="text/javascript">
// sample #1
setInterval('alert_function(1)', 1500);
 
// sample #2
setInterval(function(){ alert_function(10); }, 1500);
 
// user's alert function
function alert_function(val){
    alert("Passed parameter is: " + val);
}
</script>
