Performance Issue : Calling of change event of combobox

[former_member197888]

I have made an application and in that there is a combobox which has 2items year2014 and year2015 . Now according to the year selected data would be displayed . And on the change event of the combobox I have called a function . Just an alert is kept inside that function .

Now when i change the value of combobox the change event should be fired and immediately the alert should appear . But it takes nearly 60 seconds to display that alert which is there in that function . Can anyone guide me why is this happenenig ? And how to reduce time ?

Have a look at this example on how to implement the onChange function:

If you are doing the same, the problem must be in any other part of your code.

Manali,

Can you try using selectionChange event instead of change?

Sorry my jsbin link is leading to the wrong example.

Try to use the selectionChange event instead of "change":

<ComboBox id="system" selectedKey="2014" selectionChange="selectModel">
