When invoking an ASP.Net PageMethod, the call is made like this:
function doSomething(htmlElement)
{
PageMethods.GetText(onSuccess, onFailure);
}
Is there a recommended approach to keep a reference to the htmlElement in the scenario above, allowing for further manipulation within the onsuccess method?
Appreciate any assistance you can provide. Thank you!
Thanks to Javascript's support for closures, there is no need to be concerned about keeping track of the element reference. It's lexically scoped within onSuccess (assuming an unnamed function inline with onSuccess.)
In simple terms, the function provided for onSuccess can directly access the element reference without needing it to be passed in as a parameter.
function performAction(htmlElement)
{
PageMethods.getContent(function(x, y){ var v = htmlElement /*will not be null*/ } , onFailure);
}
