    <script src="jquery-1.9.1.js"></script>
</head>
<body>

Solution 1

Since you already have jquery code to call the webservice, just change the iframe.src in your success function of .ajax.

Solution 2

HI,

iframe has a property called src. You are using the jquery here and its very easy to append an attribute on success of the method.

Use the following code on success method.

C#

document.getElementsByID("your iframe id here").attr("src",input);

Thanks
