Hi
I am try to load a html page using jscript, I am able to load html page successfully by a click on link, but problem is loaded page is not using style sheet.
Code jscript-

$(function(){
    $('#ul1 li a').on('click', function(e){
        e.preventDefault();
        var page_url=$(this).prop('href');
        $('#content').load(page_url);
    });
});

<div id="nav" class="image002-03">
		<span id="smalltext"
            style="bottom: 0px; margin-bottom: 0px; padding-bottom: 0px; font-family: Calibri; font-size: large; text-align: center;">Service Menu</span>
		<ul id="ul1" class="serviceul">
		    <li class="serviceli"><a href="testpage1.htm">Question Papers (unsolved)</a></li>
            <li class="serviceli"><a href="#">Question Papers (solved)</a></li>
            <li class="serviceli"><a href="#">Sample Papers</a></li>
            <li class="serviceli"><a href="testpage2.htm">Notes</a></li>
            <li class="serviceli"><a href="#">Solved Assignments</a></li>
            <li class="serviceli"><a href="#">Projects</a></li>
            <li class="serviceli"><a href="#">Presentations</a></li>
            <li class="serviceli"><a href="#">Uploads</a></li>
            <li class="serviceli"><a href="#">Forum</a></li>
        </ul>
</div>

Above code load a testpage1.htm my testpage.htm code is

<head>

    <link href="css/innerPage.css" rel="stylesheet" type="text/css" />

</head>

<div id="mainbody">
    <div id="bodytext">
        Question Papers (unsolved)
        </div>
        </div>
</body>

and innerPage.css contain following style -

#mainbody
{
background-color: #FF3300;
height: 434px;
margin-top: 137px;
}
#bodytext
{
font-size: large;
font-weight: bold;
width: 214px;

If you’re testing it as a local page, you are most likely coming across a security protection.

Here’s what I get when trying to click on the question papers when the page is loaded as a local web page in google chrome:

XMLHttpRequest cannot load file:///C:/Users/Paul/Documents/sitepoint/testpage1.htm. Origin null is not allowed by Access-Control-Allow-Origin.

When the page is accessed from a web server though, things seem to work properly.
