How to call javascript function in ?

Question

I need to know how to call javascript functions in "src" also for

<input type=text>

I am using a function which returns querystring parameters

function GetUrlValue(VarSearch) {
            var SearchString = window.location.search.substring(1);
            var VariableArray = SearchString.split('&');
            for (var i = 0; i < VariableArray.length; i++) {
                var KeyValuePair = VariableArray[i].split('=');
                if (KeyValuePair[0] == VarSearch) {
                    return KeyValuePair[1];
                }
            }
        }

like if:

"www.testweb.com?a=521&b=http://demo.sacredpixel.com/redsky/wp/modern/wp-content/uploads/2013/05/gd-1.jpg"

so it will return on

alert(GetUrlValue('a')); ===> 521

but what i need is to call this function in img and input type 'text' tags.. like:

<iframe src="" id="well" width="100%" height="100%" />
<input type="text" value="" />

How to call function in above two?

i just need to call above function in input and iframe tags. — Isbah Khan, Feb 13 '14 at 06:10
use jquery, write your function GetUrlValue, receive the value of "b" and put it in like $('#well').attr('src',b); I hope you get an idea... — Pranay Bhardwaj, Feb 13 '14 at 06:12
actually i have a single page "Blog-post", and whatever value came in querystring, i will get that value by using above function, now all i need is to call this function so that my iframe and input are loaded on the start of page. — Isbah Khan, Feb 13 '14 at 06:21

I think you need this type of working. Please review it and let me know.

HTML:-

<img id="myimg" src="" />  
<input type="text" id="inputfield" value="">

JS:-

 function GetUrlValue(VarSearch) {  
        var SearchString = window.location.search.substring(1);  
        var VariableArray = SearchString.split('&');  
        for (var i = 0; i < VariableArray.length; i++) {  
            var KeyValuePair = VariableArray[i].split('=');  
            if (KeyValuePair[0] == VarSearch) {  
                return KeyValuePair[1];  
            }  
        }  
    }  

    document.getElementById('myimg').src = GetUrlValue('b');  
    //"http://www.w3schools.com/images/w3html.gif";  
    document.getElementById('inputfield').value = GetUrlValue('a');

Host the files and try this url:- "www.testweb.com?a=521&b=http://demo.sacredpixel.com/redsky/wp/modern/wp-content/uploads/2013/05/gd-1.jpg"

It worked for me. Hope it helps you.
