Introduction
There is no appropriate solution to stop <meta> tag refresh attribute or change the time interval of refresh.
I am using the <meta> tag to refresh the Page in 5 minute time intervals.
<meta id="metaAutoRefresh" http-equiv="refresh" content="300">
Problem
I want to stop the meta tag refresh when I click the checkbox of grid.
Tried but does not work
I have tired so much to solve the problem but can’t. I have tried these lines of code in JavaScript:
Example 1
To remove the <meta> tag:
<script type="text/javascript">
function onClickCheckbox()
{
var mr = document.getElementById("metaAutoRefresh");
mr.parentNode.removeChild(mr);
}
</script>
Example 2
To change the refresh time interval of <meta> tag:
<script type="text/javascript">
function onClickCheckbox()
{
document.getElementById("metaAutoRefresh").setAttribute("content", "7200");
}
</script>
Or:
<script type="text/javascript">
function onClickCheckbox()
{
$("#metaAutoRefresh").prop("content", "7200");
}
</script>
I have tried the above code to solve the stop/change the <meta> tag refresh time interval, but I can’t.
Solution
You can do it with an alternative way using JavaScript.
- Remove the code of
<meta> tag (<meta id="metaAutoRefresh" http-equiv="refresh" content="300">) from page. - Write the JavaScript code in
<head> section of page.
<script src="~/Scripts/jquery-ui-1.10.3.js"></script>
<script type="text/javascript">
var vRefreshId = null;
vRefreshId = setInterval("window.location.reload()", 5*60*1000);
function stopRefresh() {
clearInterval(vRefreshId);
}
function startRefresh() {
vRefreshId = setInterval("window.location.reload()", 5*60*1000);
}
function changeRefreshTime(vTimeInterval) {
vRefreshId = setInterval("window.location.reload()", parseInt(vTimeInterval));
}
function onClickCheckbox()
{
$('#gridClaim tr').each(function () {
if($(this).closest('tr').find
("input[id='chkSelect']").is(':checked'))
{
stopRefresh();
return false;
}
});
startRefresh();
}
</script>
gridClaim: Grid IdchkSelect: Checkbox Id
- Call
onClickCheckbox function on click of checkbox.
