jQuery treetable using events
Solution 1
You need to set the onNodeCollapse function in the settings object when the treetable is first set up.
$("#example-basic").treetable({
expandable: true,
onNodeCollapse: function() {
alert( "A branch has collapsed" );
}
});
Solution 2
Following code worked for me:
function displayNeighborhoodTableTreeDialog(treeHtml){
var nhTreeDlg;
nhTreeDlg = $("#Table_Tree").dialog({
modal: true,
title: "BCP Explorer",
height: 693, width: 525, left:0, top:0,
button: {
Ok: function() {$(this).dialog("close")}
},
show:{effect:'scale', duration:'300'},
hide:{effect:'explode', duration:'300'}
});''
nhTreeDlg.prev(".ui-dialog-titlebar").css({"background":"#47669E", "color":"white", "font-size":"13px", "font-weight":"normal"}) ;
$("div#Table_Tree").find("table#nh_table").find("tbody").html(treeHtml);
var treeRoot = $("div#Table_Tree").find("table#nh_table").find("tbody").html();
$("div#Table_Tree").find("table#nh_table").find("tbody").html(treeRoot + treeHtml);
$("table#nh_table").find("tbody").html());
$("#nh_table").treetable({
expandable: true, clickableNodeNames: false, indent:30,
onInitialized: function(){
alert("Tree table initialized");
},
onNodeCollapse: function() {
alert("Tree table Collapse");
alert($(this.row).data("tt-id") + " has collapsed");
},
onNodeExpand: function() {
alert("Tree table Expand");
alert($(this.row).data("tt-id") + " has expanded");
}});
nhTreeDlg.dialog("open");
}
The treeTable is like this
<div style='height:100%; max-height:520px;width:427px;border:1px #808080 solid;vertical-align:top;display:inline-block;overflow: hidden;'>
<div id="ttSize" style='max-height:520px;height:520px;overflow-y: scroll;'>
<table id=nh_table style='border:none;'>
<tbody>
<tr data-tt-branch='true' data-tt-id='bcp_farm'><td><span class=bcp_farm>Boardwalk Farm</span></td></tr>
<tr data-tt-id=eportal-2 data-tt-parent-id='eportal' ><td><span class=nh_0>Root</span></td></tr>
<tr data-tt-branch='true' data-tt-id='collabs-eportal-2' data-tt-parent-id='eportal-2'><td><span class=collab2>Collabs</span></td></tr>
<tr data-tt-branch='true' data-tt-id='members-eportal-2' data-tt-parent-id='eportal-2'><td><span class=members>Members</span></td></tr>
<tr data-tt-id=eportal-3 data-tt-parent-id=eportal-2><td><span class=nh_child>Buyer-XX</span></td></tr>
<tr data-tt-branch='true' data-tt-id='collabs-eportal-3' data-tt-parent-id='eportal-3'><td><span class=collab2>Collabs</span></td></tr>
<tr data-tt-branch='true' data-tt-id='members-eportal-3' data-tt-parent-id='eportal-3'><td><span class=members>Members</span></td></tr>
</tbody>
</table>
</div>

I need assistance figuring out how to use the events provided with the jQuery plugin treetable.
jQuery treetable (PLUGIN): http://plugins.jquery.com/treetable/
This is what I am trying to solve.
When a branch collapses the plugin should trigger an event called "onNodeCollapse".
When a branch collapses I just need to display a javascript popup that says "A branch has collapsed". From here I can tie it into our own functions.
I have tried several different methods as well as searching on line for a solution.

Donavon Lerman over 9 yearsThank You!!! I have been trying everything I could think of to get this to work.

Donavon Lerman over 9 yearsSorry I have a follow up question. How would I get it to display which branch has collapsed. Something like
alert( $(this).data("tt-id") + "has collapsed" );
-
Travis J over 9 years@DonavonLerman -
this
is going to contain a tree Node. As a result, you will need to access that Node's row property. You would use$(this.row).data("tt-id") + " has collapsed"
to do that. -
Donavon Lerman over 9 yearsBrilliant. Thank You. I really wish stackoverflow had a tip jar or donation button for such helpful people and answers.
