javascript function not getting executed
Question
I want to execute a javascript function in an external js file when the page is loaded. This is the code in the jsp file where the function is called from, I placed it at the bottom of the jsp
<%-- Begins countdown --%>
<script src="/pub/scripts/counter.js" type="text/javascript"></script>
<script type="text/javascript">
window.onload=startCountdown;
</script>
this is the function in the js file
function startCountdown() {
var TIMEOUT = 900000;
var COUNT_BACK = 3;
setTimeout("displayWarning("+COUNT_BACK+")", TIMEOUT);
}
when the page loads in the browser I see that the script is loaded but the startCountdown function never gets executed. How can I make this work?

我会在您的html中使用<body onload="startCountdown()"> ，以确保在执行脚本之前必须完全加载页面。

Change window.onload=startCountdown; to window.onload=startCountdown(); and use defer
<%-- Begins countdown --%>
<script defer src="/pub/scripts/counter.js" type="text/javascript"></script>
<script defer type="text/javascript">
window.onload=startCountdown();
</script>
this is the function in the js file
var startCountdown = function() {
var TIMEOUT = 900000;
var COUNT_BACK = 3;
setTimeout("displayWarning("+COUNT_BACK+")", TIMEOUT);
};
