quiz question - Having problem creating for the HTML element's value using JQuery [duplicate]

//Get
var bla = $('#txt_name').val();

//Set
$('#txt_name').val(bla);

You can only select a value with the following two ways:

// First way to get a value
value = $("#txt_name").val(); 

// Second way to get a value
value = $("#txt_name").attr('value');

If you want to use straight JavaScript to get the value, here is how:

document.getElementById('txt_name').value 

There is one important thing to mention:

$("#txt_name").val();

will return the current real value of a text field, for example if the user typed something there after a page load.

But:

$("#txt_name").attr('value')

will return value from DOM/HTML.


You can get the value attribute directly since you know it's an <input> element, but your current usage of .val() is already the current one.

For the above, just use .value on the DOM element directly, like this:

$(document).ready(function(){
  $("#txt_name").keyup(function(){
    alert(this.value);
  });
});
