replace prompt with UI dialog

Question

How can I replace the prompt in this code with a simple UI dialog to achieve the same thing. IE is warning about security when using prompt.

HTML:

<input type="text" id="txt1" name="textbox1">
<input type="button" id="btn" name="buttonExecute" value="Enter number">

JavaScript:

$('#btn').click(function() {
    var n = prompt('Please enter number');
    if ( n!=null && n!="" ) {

    var fixed=n.substr(1,9);

     $('#txt1').val(fixed);
    }
});

Use jQuery UI.
