Question

How can I update a multiple textboxes value with Javascript, when user change the value of textboxes,
and I have a value already on those textboxes?

Am I doing in the right track on the code below?

<input type="text" id="amount_textbox" onChange="UpdateValue()" value="100">
<input type="text" id="amount_textbox" onChange="UpdateValue()" value="200">
  function UpdateValue()
     {
        //alert ("you have changed the textbox...");
        var x = document.getElementById('amount_textbox').value;
        document.getElementById("amount_textbox").setAttribute("value", x);
        document.getElementById('amount_textbox').value = x;
     }

That function is working only for the first textbox, the second one can not update, how can I make other textbox work?

Answer 1

in jquery

$("#text").val("my new value");

in javascript

document.getElementById("text").setAttribute("value", "my new value");

document.getElementById('text').value = 'Blahblah';
