I have a method in my Default.aspx page and I would like to know how can I call this method every 5 seconds through JavaScript ?
protected void GetSlideNumber()
{
var repos = new PresentationService();
int slide = repos.GetSlideNumber();
ceckSlide.Text = slide.ToString();
}
Make this method as [WebMethod] and use AJAX to all this method
$.ajax({
type: "POST",
url: "PageName.aspx/MethodName",
data: "{}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function(msg) {
// Do something interesting here.
}
});
Refer Web Method

Use AJAX it can help you. More information can be found at this link.
$.ajax({ type: "POST",
url: pageMethod,
data: "",
success: function (result, status) {
alert("success");
},
error: function (xhr, status, error) {
alert("ERROR");
}
});
like below..
<script>
window.setInterval(function(){
GetSlideNumber()
}, 1000);
</script>
Try this..
<script>
function sample()
{
alert("<%=GetSlideNumber()%>");
}
</script>
