带checkbox的树形菜单

dtree_checkbox.js

1.判断并选中checkbox
       //选中该用户所拥有的权限
       var menu_id_check=new Array();
       menu_id_check="<s:property value='#request.purviewRoleList'/>".split(",");
       //为角色原有权限的checkbox打上已选标记
$(':checkbox').each(function(){
for(var j=0;j<menu_id_check.length;j++){
if(this.value==menu_id_check[j]){
this.checked=true;
break;
}
}
});
2.显示带checkbox的复选框
<form action="savepurview.action" method="post" id="purviewForm">
                <input type='checkbox' id='purview_check_all' onclick='checkall()'/>全选
              <input type="hidden" name="role_id" value="<s:property value="#request.purviewAllList[0].role_id"/>"/>
                <script language="JavaScript" type="text/JavaScript">
    var d = new dTree('d','<%=request.getContextPath()%>','purviewForm');
    <s:iterator value="%{#request.purviewAllList}" id="functionNode">
        d.add('${functionNode.menu_id}','${functionNode.parent_id}','${functionNode.menu_name}');
    </s:iterator>
    document.write(d);
    </script> 
               
  <div class="operation">

          <input type="button" value="保存" class="button" onclick="submitForm()"/>
          <input type="button" onclick="history.back()" value="返回" class="button"/>
      </div>
