Hello, last video I show you how you can use a tap listener to write some code once the user presses a tab or lift a tap in this video I will talk about input text listener This one is the most important feature you can work with. So I for example, I will track here the MBE as a for this okay so here you have some Bennett steps, so you have some input tickets. Okay, so this is the input tickets. So if you want the user once he changed the value of the input tickets, you want to make some business some code you want to do something. For example, if if I want to show a face Select is a first name or you need to sit the last name to be the same like first name or once the first name is change the salary set to a specific value, if you want to anything if you want to catch you the value change listener is a value would change it in the back been and to do something you can do it in the value change listener of the input text.

This is do some example I need once the user enters the first name since the last name with the same value of the first name okay. So, this is the input tickets. So, I need to go to the behavior most of the listener means a behavior you will find here, when you change a listener. It means once the value of this input text change it the value change listener will be fired. So I will point this listener to the backbeat. I will select my piece been can see first name His name value change listener okay in the listener will have an object was the listener also evident from this listener you can get some value.

So, let us here just print the new value. So, we can take this object from the event to listener take copy and I will call here in new intern value is and let us print it from this object dot get you will find here new value and all the value if you want the good old value before user change it or if you want to get the new value. So, I would say I need to get the new value Okay, so I will print it here after that I need to set the last name to be the same first name so we will do the same I will get the binding from the binding or we'll get a traitor from a traitor I will get the current through after I get the current rule I can easily sit or get any value from the current rule.

So, I will I will here quotas are binding from the binding I will go to towards the end when we I traitor and from the MBA traitor, I will get the current true after I get the current rule. I will say all those sit attribute I need to sit attribute with you Okay, this what only need you just to set the attribute which is the last name this is take the attribute name, I will go to the View object which is this I treat or point to that attribute name last name. Yes. So this is a very she doesn't have the first name, I will get the new value so users user interface. After that I would get the current row and set the last name was UVA. For any input for any input tickets, do you want to register to be run once the user lift is in blue tickets Do you have to sit in auto submit to this invalid tickets to be true?

So I will go to the Ember tickets, the first name, auto submit, I will make it true. So this is actually should be both together. If you add any value change listener for any tickets Do you have to add auto submit to withdraw without also Mr true wants you to change the value in the tickets nothing will happen unless you sit at summit to be true in that case it will be fine. The second thing is once you want this last name to be updated once the user enters a value, so, you have to add the Basha trigger in the last name boy into that this input the first name so I will take the ID of the first name and I would add it in the partial trigger of the last name Okay, so let us now try to run and check the value change listener of the input tickers.

This is you can you will use this a lot in your ADF application. Sometimes you want to execute some code Once a user enter value, so you can use it use a value change listener example text. Okay, so in this now go to the input text with a tab which we added here. So now I need once I change the first name, the last name should be change. So with skinnier here's a look. And there it is, Ed here 123 you'll find here the new value is 123 and the last name is changed automatically.

So, the value change is not actually will happen once you lift. So if you change the value, mostly will happen unless you lift this component if every step for example, it will fire the value change is not all if you click outside so if you are inside this and the click outside, you lift the components a value change listener We'll be fired. This is how you can catch the value change with in some input tickets. In case if you want to write some code or to make some check or to get data from somewhere and set some other things, you can do whatever you want. Once a user change the value of specific input tickets, you can go to this input text and set a value change listener to a method in a bag bean and you can set it to submit through so that it will be triggered So for example, if you didn't sit would submit withdraw it just try it.

I didn't sit it on submit withdrew of the first name. Let us refresh the page. Okay, and just this change it is it not cinco We change nothing happen. Why? Because you didn't sit Submit. So, the most important thing if you want the value change listen to hits back pain, you have to sit an old submit equal true key Zed keys on suit in exhibit you will find solutions to listener is hit OK.

So, this is how you work with value change results in particular, same in the input data as one example data you will find here. Value change listener so same, like in verticals in widget will be the same value change. This is how you can catch the value change listener in the input tickets next video, we'll go to Tools drop down lists. So see you in activity.
