------上级状态改变(勾选或取消勾选)，所有下级状态跟着改变 ,在tree控件的onCheck事件中实现---------

cascadeCheck: false,//默认为true表示上下级勾选联动，false表示取消联动
onCheck: function (node, checked) {
var childList = $(this).tree('getChildren', node.target);

if (childList.length == 0) return;

var checkedTrue = function () {
childList.map(function (currentValue) {
var objTrue = $("div[id='" + currentValue.domId + "']").find(".tree-checkbox");
if (objTrue != null && objTrue != undefined) {
var classTrue = objTrue.attr("class");
if (classTrue == "tree-checkbox tree-checkbox0")
objTrue.removeClass("tree-checkbox tree-checkbox0").addClass("tree-checkbox tree-checkbox1");
}
});
};

var checkedFalse = function () {
$.each(childList, function (index, currentValue) {
var objFalse = $("div[id='" + currentValue.domId + "']").find(".tree-checkbox");
if (objFalse != null && objFalse != undefined) {
var classTrue = objFalse.attr("class");
if (classTrue == "tree-checkbox tree-checkbox1")
objFalse.removeClass("tree-checkbox tree-checkbox1").addClass("tree-checkbox tree-checkbox0");
}
});
};
var checkChangeProperties = checked == true ? checkedTrue() : checkedFalse();
}
