How can I access a server-side asp.net variable in JavaScript? I'm trying to achieve something like this:
function setBookmark(val)
{
document.getElementById('<%# hBookmark.ClientID %>').value=val;
}
Is there any way to accomplish this?
*Note*: hBookmark is a server-side HTML hidden control, and I want to use the client ID since IDs change as server controls are rendered.
// Remember to use <%= instead of <%#
update the value of the element with the id '<%=hBookmark.ClientID%>' to the variable 'val';
One way to incorporate scriptlets is by using the following code...
document.getElementById('<%= hBookmark.ClientID %>').value = val;
Keep in mind that the Javascript cannot be stored in an external file; it must be within the markup for it to be effective.
You have the option to assign the variable as a value for a hidden input field
<input type="hidden" value="<%= hBookmark.ClientID %>" id="hBookmarkClientID" />
After that, you can access it using JavaScript
function updateBookmark(value)
{
var hBookmarkClientID = document.getElementById('hBookmarkClientID').value;
document.getElementById(hBookmarkClientID).value = value;
}
