值变更事件和点击事件

Question

I have a JSF page with value change listeners on input field, and a button to save the changes. When I change a value on them and tab out of the field, the validation fires and everything works fine. But when I change a value and, without tabbing out, click on the Save button, the value change event fires, but its Button's click action is not fired. How to get around this so that I can have both events firing sequentially?

Answer 1

With "p:clientValidator" in the fields you want to validate and the property validateClient="true" in your p:comandButton primefaces does the work for you.

Take a look at this example: validate client

Answer 2

My guess is that its beacause of multiple ajax requests...

What happens is when you clicking on your submit button your input filed is getting blurred and thus triggering its chnage event which in turn sends an ajax to your server which in turn making your submit button ajax request to get lost (you can't send two ajax at once/one click)

I suggest you to replace your input change event into keyup event to prevent your double ajax sending scneario
