Question

I have this code to validate if a field is empty or not. It is binded into the blur event of a input with an anonymous function.

isValidText = function(){        
    if ($(this).val().trim() == ""){
        //some code here
        return false;
    }
    //some code here
    return true;
}

$("#someElement").blur(isValidText);

At a certain point, I want to get the returning value from the binded function doing something like this:

//this return a jQuery object
var isValid = $("#someElement").blur(); 
//but I want the boolean from the isValidText

This is not possible because the blur() method return a jQuery object and not the return value of the isValidText function.

My question here is if there is a way to get the return value from the isValidText binded inside the blur event.

Answer 1

$("#someElement").blur(function() {
   var ret = isValidText.call(this); 
});

OR

$("#someElement").blur(function() {
   var ret = isValidText.apply(this, arguments); // if you work with some hadler
});
