zk tree的checkbox要如何抓取资料呢?

时间：2011-01-03

来源：互联网

各位好,我想请问一下问题,我需要利用tree来呈现出项目(从资料库中抓取出来),让使用者勾选,然后储存至资料库,但现在画面上是完成了,但却不晓得要如何让画面呈现checkbox的预设值(从资料库抓该user的资料),以及抓取user勾选的值来让我做后续储存的动作
底下是zkdemo里画面类似的范例：

<tree id="tree" width="400px" rows="8" checkmark="true" multiple="true">
  <treecols sizable="true">
    <treecol label="Name" />
    <treecol label="Description" />
  </treecols>
  <treechildren>
    <treeitem>
      <treerow>
        <treecell label="Item 1" />
        <treecell label="Item 1 description" />
      </treerow>
    </treeitem>
    <treeitem>
      <treerow>
        <treecell label="Item 2" />
        <treecell label="Item 2 description" />
      </treerow>
      <treechildren>
        <treeitem>
          <treerow>
            <treecell label="Item 2.1" />
          </treerow>
          <treechildren>
            <treeitem>
              <treerow>
                <treecell label="Item 2.1.1" />
              </treerow>
            </treeitem>
            <treeitem>
              <treerow>
                <treecell label="Item 2.1.2" />
              </treerow>
            </treeitem>
          </treechildren>
        </treeitem>
        <treeitem>
          <treerow>
            <treecell label="Item 2.2" />
          </treerow>
          <treechildren>
            <treeitem>
              <treerow>
                <treecell label="Item 2.2.1" />
              </treerow>
            </treeitem>
          </treechildren>
        </treeitem>
      </treechildren>
    </treeitem>
    <treeitem label="Item 3" />
  </treechildren>
</tree>
