Hi,

I am using Type Ahead Text which works fine for me but when I implemented On Change event it fires twice

Example:  if I have a number 9000011111  . I start clicking in Type Ahead Text 900 then the control finds it and I click on the found item which is 9000011111 the On Change event  fire twice first 900 and then the full number 9000011111 is that correct behavior

Thanks.

Hi Alex,

I have observed the same behavior.  This is due to the fact that technically, the input for the control has change when the user clicks away from the input field.  The user also happens to be clicking into the popup menu, which sets the value of the input control.  Thus change is actually happening twice.  This is necessary though, as when the user clicks away somewhere else on the screen, the change needs to be fired for evaluation purposes.

We are looking into providing a method that will return true of false if the value is in the list of items.  Then, the developer can decide whether or not to proceed with the logic in the change event.

Hi Alex,

Keep in mind that if the user navigates with the keyboard and selects a list item, the even will only fire once.

Hi Alex,

You can check the itemList in context options:

if(me.context.options.itemList.get(“value”).items.indexOf(me.getData()) > -1){console.log(“On Change triggered”);}
