Programmatically adding child nodes to a jstree
I'm trying to write some code that adds nodes to a jstree dynamically. I've followed the doc at http://www.jstree.com/documentation/crrm but can't get a simple example to work -- the node child2 is being added, but it is being added to the node 'root.id' rather than 'child1.id' as specified... Any tips would be much appreciated. Code follows
<html>
<head>
<script type="text/javascript" src="http://static.jstree.com/v.1.0rc2/jquery.js"></script>
<script type="text/javascript" src="http://static.jstree.com/v.1.0rc2/jquery.jstree.js"></script>
<script type="text/javascript">
$(document).ready(function() {
$(function () {
$("#tree").jstree({
"json_data" : {
"data" : [
{
"data" : "parent",
"attr" : { "id" : "root.id" },
"children" : [ { "data" : "child1",
"attr" : { "id" : "child1.id" },
"children" : [ ] }
]
},
]
},
"plugins" : [ "themes", "开发者_开发技巧json_data", "crrm" ]
});
});
$("#add").click(function() {
$("#tree").jstree("create", $("#child1.id"), "inside", { "data" : "child2" },
function() { alert("added"); }, true);
});
});
</script>
</head>
<body>
<div id="tree" name="tree"></div>
<input type="button" id="add" value="add" />
</body>
</html>
When using periods in ID's you need to escape them like so:
$("#tree").jstree("create", $("#child1\\.id"), "inside", { "data" : "child2" },
function() { alert("added"); }, true);
This is because of how it uses jQuery selectors. It is mentioned in the jsTree FAQ located here: http://www.jstree.com/faq/
first initialize jstree(in my case i use ajax), put check_callback into core obj and call the plugin after core obj like this:
jQuery('#jstree_demo_div').jstree({
'core' : {
'data' : {
'url' : 'data/mapas.php',
},
"check_callback" : function(e,data){
console.log(data)
}
},
"plugins" : [ "contextmenu" ] })
second use this line and put $('#j1_1') as parent , the data in json, 'last' as position or 'first', the function callback (in my case is the function tales()), internal argument set in true
jQuery("#jstree_demo_div").jstree(true).create_node( $('#j1_1'), {text: "New node", id: true} , "last",tales(), true );
