Question

How to add the validation to textbox control in focusout event only?

Does anyone have an idea?

Answer 1

$("#txt1").blur(function(){
  var v = $("#txt1").val();
  if(v == "test"){
    alert('valid');
  }
  else{
    alert('invalid');
  }
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
T1: <input type="text" id="txt1">
T2: <input type="text" id="txt2">

Refer: https://api.jquery.com/focusout/

.focusout(function() {

    // Put your validation code here
    if(!valid){
        return false;
    }    
})

OR

.blur(function() {

    // Put your validation code here
    if(!valid){
        return false;
    }    

})

Answer 2

Your html is:

<input type="text">

And your jQuery:

$('input').blur(function(){
    var text = $(this).val();
   //do smth with your text...
});
