Restrict keyboard Input to Textbox JavaScript

How do i restrict user to enter any data from Keyboard to Text-box. Actually my requirement is that, this particular textbox is being used for only scanning purpose. Hence, only scanned data will be entered to this textbox and want to restrict any manually entered data from keyboard.

If you want to fill data from backend then you can permanently disable for that you just need to add in textbox html readonly and then fill value by

document.getElementById("yourtextbox_id").value="your_scanned_value";

SAMPLE FIDDLE

I dont think there is any need of javascript here.

Just use readonly in you html.

 <input value="somevalue" name="meow" readonly>

Thats it.No fancy javascript needed.

Just disable the textbox and get the value from the backend will solve the issue.

Try this

$(function(){
   $('input[type=text]').bind('keyup keydown keypress', function (evt) {
       return false;
   });
});
