jQuery EasyUI Tree Menu - TreeGrid Lazy Loading Nodes
Sometimes we already have fully hierarchical TreeGrid data. We also want the TreeGrid to load nodes lazily by level. First, only load the top-level nodes. Then, click a node's expand icon to load its child nodes. This tutorial shows how to create a TreeGrid with lazy loading.
Create TreeGrid
To load child nodes, we need to rename the 'children' property for each node. As shown in the code below, the 'children' property is renamed to 'children1'. When a node is expanded, we call the 'append' method to load its child node data.
'loadFilter' Code
function myLoadFilter(data,parentId){
function setData(){
var todo = [];
for(var i=0; i<data.length; i++){
todo.push(data);
}
while(todo.length){
var node = todo.shift();
if (node.children){
node.state = 'closed';
node.children1 = node.children;
node.children = undefined;
todo = todo.concat(node.children1);
}
}
}
setData(data);
var tg = $(this);
var opts = tg.treegrid('options');
opts.onBeforeExpand = function(row){
if (row.children1){
tg.treegrid('append',{
parent: row[opts.idField],
data: row.children1
});
row.children1 = undefined;
tg.treegrid('expand', row[opts.idField]);
}
return row.children1 == undefined;
};
return data;
}
