java,jsp带checkbox的树形菜单，如何实现？jsp中带有checkbox的属性菜单需要用easyui组件来实现java树形菜单系统代码，代码如下java树形菜单系统代码：

pTree nodes with check boxes./p
div style="margin:20px 0;"
a href="https://www.04ip.com/post/#" class="easyui-linkbutton" onclick="getChecked()"GetChecked/a
/div
div style="margin:10px 0"
input type="checkbox" checked onchange="$('#tt').tree({cascadeCheck:$(this).is(':checked')})"CascadeCheck
input type="checkbox" onchange="$('#tt').tree({onlyLeafCheck:$(this).is(':checked')})"OnlyLeafCheck
/div
div class="easyui-panel" style="padding:5px"
ul id="tt" class="easyui-tree" data-options="url:'tree_data1.json',method:'get',animate:true,checkbox:true"/ul
/div
script type="text/javascript"
function getChecked(){
var nodes = $('#tt').tree('getChecked');
var s = '';
for(var i=0; inodes.length; i++){
if (s != '') s += ',';
s += nodes[i].text;
}
alert(s);
}
/script
/body
/html
