Javascript Login Value

Question

how can i pass the value from input 1 to 2 and add some letters?

<script type="text/javascript"> function doit(){ document.getElementById('input2').value=document.getElementById('input1').value; } </script> 

Entrance 1: 2342

Input2: pcid2342d

Can someone help me?

Answer 1

Just use the + operator to add a line before and after the input value.

 <script type="text/javascript"> function doit(){ document.getElementById('input2').value="pcid" + document.getElementById('input1').value + "d"; } </script> 

Answer 2

String concatenation:

 document.getElementById('input2').value = "stuff" + document.getElementById('input1').value + "other stuff"; 

When working with numbers, you can start by concatenating with an empty string, so as not to add numbers together, and not to concatenate strings (due to the order in which the operator is evaluated):

 document.getElementById('input2').value = "" + 1234 + 567 + document.getElementById('input1').value + 89; 

Answer 3

Well, it looks like you have already done the work, you just need to click to complete it:

 <button onclick="doit()">click me</button> 

Answer 4

Why don't you try something in jQuery?

  $("#Anything").click(function() { $("#Field1").val($("#Field2").val()); }); 

"click" is just a guess =)
