Expand parent node after populating a treeview

[ohad]

Hi,

 

I populate a tree view from database using jquery and ajax.

the next phase I want is to expand a scpecific parentId.

Here is my code:

<div class="col md-2" id="treeview_json">
                
</div>

$(document).ready(function()
{
	var pageURL = $(location).attr("href");
    var url = '/path/to/fill_sidebar.php';
    $.ajax
    ({
    	type: "GET",  
        url: url,
        dataType: "json",   
        success: function(data)  
        {
	        var parent_node_id;
            var onTreeNodeSelected = function (e, node) 
            {
	            GetNodeData(node.link, node.tags)
            }
            $('#treeview_json').treeview
            ({
 	         	data: data,
                backColor: 'white',
                expandIcon: 'fa fa-plus fa-fw',
                collapseIcon: 'fa fa-minus fa-fw',
                showBorder: false,
                enableLinks: true,
                onNodeSelected: onTreeNodeSelected,
            });
       },
       error: function(response)  
       {
       		alert(response.errorMsg);
       } 
   });
});

I want to get a specific parentId of a node and after filling the treeview, i want to expand it

something like 

$('#treeview_json').treeview('expandNode', [node.parentId]);

Can anyone explain to me how can I do that?

 

Thank you

You need to read the documentation for whatever tree view library you are using and figure it out.  There is no standard tree view widget so there's no standard way to do what you want.

If you can't figure it out from the documentation, then at the very least you need to specify which library you are using to get help with it.

Hi,

Thanks for the clarification.

I tried look at the documentation, and I didn't find.

Its bootstrap-treeview version 1.2.0 of Jonathan Miles. https://github.com/jonmiles/bootstrap-treeview

It's weird you mention that because the very same documentation you couldn't find says that's exactly what you're supposed to do.
Could it be that your question isn't so much "how" but rather "why does this method call not work"?

Where are you putting that code? Where did "node" get defined? Any errors in the browser's console?

I saw in the documentary how to expand a node.

My problem is that I don't know which event should trigger the expanding.

I need an event like onNodeSelected that call a function that do that expansion. The node will be defined under that function

I hope i explained myself better

Thank you

I thought you said that you wanted to expand a node after filling in the tree. That isn't an event: you have code to fill in the tree so add a bit of code after that happens to expand the node.
