How to get text box value in JavaScript

Your element does not have an ID but just a name. So you could either use getElementsByName() method to get a list of all elements with this name:

var jobValue = document.getElementsByName('txtJob')[0].value  // first element in DOM  (index 0) with name="txtJob"

Or you assign an ID to the element:

<input type="text" name="txtJob" id="txtJob" value="software engineer">

+1 Gumbo: ‘id’ is the easiest way to access page elements. IE (pre version 8) will return things with a matching ‘name’ if it can't find anything with the given ID, but this is a bug.

i am getting only "software".

id-vs-name won't affect this; I suspect what's happened is that (contrary to the example code) you've forgotten to quote your ‘value’ attribute:

<input type="text" name="txtJob" value=software engineer>

var word = document.getElementById("word").value;//by id
or
var word = document.forms[0].elements[0].value;//by index
//word = a word from form input
var kodlandi = escape(word);//apply url encoding

alert(escape(word));
or
alert(kodlandi);

the problem you are not using encoding for input values from form so not browser adds ones to ...

ontop has some problems as unicode encoding/decoding operations so use this function encoding strings/arrays

function urlencode( str ) 
{
// http://kevin.vanzonneveld.net3.    
// +   original by: Philip Peterson4.    
// +   improved by: Kevin van Zonneveld (http://kevin.vanzonneveld.net)5.    
// *     example 1: urlencode('Kevin van Zonneveld!');
// *     returns 1: 'Kevin+van+Zonneveld%21'7. 
   var ret = str; 
   ret = ret.toString();
   ret = encodeURIComponent(ret);
   ret = ret.replace(/%20/g, '+');
   return ret;
}


ex.
var word = "some word";
word = urlencode(word);

<!DOCTYPE html>
<html>
<body>
<label>Enter your Name here: </label><br>
<input type= text id="namehere" onchange="displayname()"><br>


<script>
function displayname() {
    document.getElementById("demo").innerHTML = 
document.getElementById("namehere").value;
}

</script>


<p id="demo"></p>

</body>
</html>
