多个事件触发相同的函数

Is there a way to have keyup, keypress, blur, and change events call the same function in one line or do I have to do them separately?

The problem I have is that I need to validate some data with a db lookup and would like to make sure validation is not missed in any case, whether it is typed or pasted into the box.

    You can use .on() to bind a function to multiple events:

    $('#element').on('keyup keypress blur change', function(e) {
        // e.type is the type of event fired
    });
    

    Or just pass the function as the parameter to normal event functions:

    var myFunction = function() {
       ...
    }
    
    $('#element')
        .keyup(myFunction)
        .keypress(myFunction)
        .blur(myFunction)
        .change(myFunction)
