Question

我想用这个html文件中的文件夹和子文件夹构建一个分层的dojo树菜单：

<div id="prelude"><h2>Pr&eacute;lude</h2></div>
<div id="_BaseTestsAsync_00_NUnitIsWorking_Passed">_BaseTestsAsync_00_NUnitIsWorking<br/>Yo!</div>
<div id="_BaseTestsAsync_01_TwincatisRunning_Passed"><h2><font color="darkgreen">_BaseTestsAsync_01_TwincatisRunning</font></h2></div>
<div id="_BaseTestsAsync_02_CorrectPLCModuleIsActive_Passed">_BaseTestsAsync_02_CorrectPLCModuleIsActive</div>
<div id="AsynchronousTests_read1600OutsideRange_Passed"><h2>AsynchronousTests_read1600OutsideRange</h2></div>
<div id="AsynchronousTests_readNonEmpty1600_1_Passed"><h2>AsynchronousTests_readNonEmpty1600_1</h2></div>
<div id="AsynchronousTests_readUnknownRegister_Passed">AsynchronousTests_readUnknownRegister</div>
<div id="Robustness_WriteCurrentPosition_Passed"><h2><font color="darkgreen">Robustness_WriteCurrentPosition</font></h2></div>
<div id="Robustness_WriteIllegalSpeedPosition_Passed">Robustness_WriteIllegalSpeedPosition</div>
