How can one write correct HTML to an inline Javascript inside a JSP?
Question
Due to some reasons, I have to load two separate page header HTMLs in my page. One of them is a header for mobile view, and the other is for the desktop view. The rest of my page is responsive. My plan is to load both headers' HTMLs inside a JS that loads on page load and depending on page width populate the correct header's HTML inside my page, and hope the corresponding JS and CSS to load. I am doing this since the JS and CSS of the two header HTMLs are prone to clashing (and I can't tinker with these HTMLs), so I want only of them to load on a page load.
The problem is in writing HTML in JSP inside this inline JS. I repeatedly get errors like "Uncaught SyntaxError: Unexpected token ILLEGAL".
My code in JSP looks like this:
<c:when test="${not empty hdrLoggedInHtml and not empty hdrLoggedInHtml_M}">
<script type="text/javascript">
$(document).ready(function(){
if($(window).width()>420)
{
$("#desktopHeader").html('<c:out value="${hdrLoggedInHtml}" escapeXml="false"/>');
$("#mobileHeader").html("");
}else
{
$("#mobileHeader").html('<c:out value="${hdrLoggedInHtml_M}" escapeXml="false"/>');
$("#desktopHeader").html("");
}
});
});
</script>
</c:when>
I tried using fn:escapeXml but that didn't work either. It seems to me that the new line after <html> inside the string is not getting output properly or some invisible character is coming somehow. Please help.

Put hdrLoggedInHtml into a html node which is display:none before it,like:
<script>
var global = {} ; global.url = '${url}';global.data = $.parseJSON('${data}');
</script>
and then,put the script at the bottom of the JSP page ,here is one example:
<script type="text/javascript">
$(document).ready(function(){
if($(window).width()>420)
{
$("#desktopHeader").load(global.url,global.data);
$("#mobileHeader").html("");
}else
{
$("#mobileHeader").html($('#'));
$("#desktopHeader").html("");
}
});
});
