jquery easyui的tree控件

Question

jquery easyui的tree控件 $('#tree').tree("select", node.target)中node是存在的，为什么选中后functiontree.tree('getSelected')值一直为空

Answer 1

function moveUp() {
    if ($("input[id$='_hidSelectId']").val() != "") {
        $.ajax({
            type: 'get',
            url: '../../../Service/FunctionManageHander.ashx?action=moveUp&oid=' + $("input[id$='_hidSelectId']").val(),
            dataType: 'json',
            success: function (data) {
                if (data.type == "1") {
                    var selectnode = functiontree.tree('find', $("input[id$='_hidSelectId']").val());
                    var parentnode = functiontree.tree('getParent', selectnode.target);
                    functiontree.tree('reload', parentnode.target);
                    functiontree.tree("select", selectnode.target);                } else {
                    functiongrid.datagrid({ url: '../../../Service/FunctionManageHander.ashx?action=list&PID=' + functiontree.tree('getSelected').id });
                }
            }
        });
    }
}红色选中的没有选中
蓝色取不到值

Answer 3

知道原因了，'reload'后不能选中节点，那我要选中，要怎么操作？

var selectnode = functiontree.tree('find', $("input[id$='_hidSelectId']").val());
