I have just started with fancytree 2.6.0 and I am populating it from a web service request.
My problem is that all the nodes are present but are made invisible by the ui-helper-hidden class. I have put in a temporary fix with: $(rootNode.ul).removeClass('ui-helper-hidden'); but I am sure I am missing something.
The scripts and css:
<link href="Scripts/jquery-plugins/fancytree-2.6.0/src/skin-themeroller/ui.fancytree.css" rel="stylesheet" type="text/css" />
<script src="Scripts/jquery-1.11.1/jquery-1.11.1.js" type="text/javascript"></script>
<script src="Scripts/jquery-1.11.1/jquery-migrate-1.2.1.js" type="text/javascript"></script>
<script src="Scripts/jquery-ui-1.11.2/jquery-ui.js" type="text/javascript"></script>
<script src="Scripts/jquery-plugins/fancytree-2.6.0/src/jquery.fancytree.js" type="text/javascript"> </script>
<script src="Scripts/jquery-plugins/fancytree-2.6.0/src/jquery.fancytree.themeroller.js" type="text/javascript"> </script>
The code:
$('#selectedClausesDiv').fancytree();
$.when(
$.getJSON("Handlers/GetQuotationHandler.ashx?jsoncallback=?", { quoteReference: quoteReference, quoteVersion: quoteVersion })
).then(function (data) {
if (data.ErrorCode == 0 && data.Quotation != null) {
var rootNode = $("#selectedClausesDiv").fancytree("getRootNode");
$.each(data.Quotation.Covers, function (index, item) {
addCover(rootNode, item);
});
// FIXME: why is this necessary ??
// $(rootNode.ul).removeClass('ui-helper-hidden');
}
});
function addCover(rootNode, cover) {
var coverId = 'selected_' + cover.BusinessClassId + '_' + cover.CoverId;
var coverNode = rootNode.addChildren({
title: cover.Name,
tooltip: "This folder and all child nodes were added programmatically.",
folder: true
});
}
The generated html:
<div class="grid_13 alpha omega" id="selectedClausesDiv">
<ul class="ui-fancytree fancytree-container ui-fancytree-source ui-helper-hidden" tabindex="0">
<li class="">
<span class="fancytree-node fancytree-folder fancytree-exp-n fancytree-ico-cf">
<span class="fancytree-expander"/>
<span class="fancytree-icon"/>
<span title="This folder and all child nodes were added programmatically." class="fancytree-title">P&I Owned</span>
</span>
</li>
<li class="fancytree-lastsib">
<span class="fancytree-node fancytree-folder fancytree-lastsib fancytree-exp-nl fancytree-ico-cf">
<span class="fancytree-expander"/>
<span class="fancytree-icon"/>
<span title="This folder and all child nodes were added programmatically." class="fancytree-title">P&I Extended Cargo</span>
</span>
</li>
</ul>
</div>
Fancytree will automatically hide the root element if no data source is provided.
If you are adding data using the API and no initial source, providing a blank
source
option will prevent Fancytree from hiding the root element.
