External Page Content Overflows out of Bootstrap Modal - html

Question

I have the following Modal:
<a href="somepage.htm" data-toggle="modal" data-target="#extLinkModal">
<div class="modal fade" id="extLinkModal" tabindex="-1" role="dialog" aria-labelledby="extlinkModalLabel" aria-hidden="true" data-backdrop="static">
<div class="modal-dialog " role="document">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button>
<h4 class="modal-title" id="extLinkModalLabel"></h4>
</div>
<div class="modal-body">
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
When I click the link to launch modal, the content of somepage.htm overflows out of the modal and there are no scroll bars on the modal?
How come this is happening?

Answer 1

Let's say you have 2 pages, index.htm and somepage.htm
you have modal in page index.htm and you want to show somepage.htm inside modal. Then
index.htm page code will be
<a href="somepage.htm" data-toggle="modal" data-target="#extLinkModal">
<div class="modal fade" id="extLinkModal" tabindex="-1" role="dialog" aria-labelledby="extlinkModalLabel" aria-hidden="true" data-backdrop="static">
<div class="modal-dialog " role="document">
<div class="modal-content">
//Here you can show the content from `somepage.htm`
</div>
</div>
</div>
and somepage.htm page content will be
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button>
<h4 class="modal-title" id="extLinkModalLabel"></h4>
</div>
<div class="modal-body">
//Put the page content here
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
This will resolve the issue somepage.htm overflows out of the modal and there are no scroll bars on the modal
Alternate Solution
OP asked in comments to load the remote page content into modal-body and above code example is default behavior of bootstrap v3+ where modal ignores the modal-body and always load the remote content into <div class="modal-content"> doesn't matter even if <div class="modal-body"> exist inside the <div class="modal-content">.
To get around this and make sure that the remote content load inside <div class="modal-body">
Use bootstrap modal events
Do not use href or remote in modal call button or link
So the modal call button or link will be
<a datalink="somepage.htm" data-toggle="modal" data-target="#extLinkModal" class="btn btn-primary">
where href changed to datalink or any word can be used but not href or remote otherwise modal will detect it as remote content and ignores the <div class="modal-body"> and load the content into <div class="modal-content">
Modal HTML
<div class="modal fade" id="extLinkModal" tabindex="-1" role="dialog" aria-labelledby="extlinkModalLabel" aria-hidden="true" data-backdrop="static">
<div class="modal-dialog " role="document">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button>
<h4 class="modal-title" id="extLinkModalLabel"></h4>
</div>
<div class="modal-body">
//Remote Page Content loads here
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
and JS
<script>
$(document).ready(function() {
$("#extLinkModal").on("show.bs.modal", function(e) {
var link = $(e.relatedTarget);
$(this).find(".modal-body").load(link.attr("datalink"));
});
});
</script>

Answer 2

The content of somepage.htm overflows out of the modal because your somepage.htm page is not responsive, and your modal have some fixed height and width. So try to make your page responsive using bootstrap classes and some additional css if needed.
So making somepage.htm page content responsive will solve both problems of content overflows out of the modal as well as scroll bar.
Hope it will help you!
