为了修改timeslider下方的label值，我须要获取相应的标签才能够。

首先我作了这样的尝试：

 $(".tsTmp table> tbody tr")[2];获取到了下方整个lebel但并非我想要的。

<tr class="dijitReset"><td class="dijitReset" colspan="2"></td><td data-dojo-attach-point="containerNode,bottomDecoration" class="dijitReset dijitSliderDecoration dijitSliderDecorationB dijitSliderDecorationH"><div class="dijitRuleContainer dijitRuleContainerH" id="dijit_form_HorizontalRule_1" widgetid="dijit_form_HorizontalRule_1" style="height: 1em; font-size: 75%; color: gray;"><div class="dijitRuleMark dijitRuleMarkH" style="left:0%;"></div><div class="dijitRuleMark dijitRuleMarkH" style="left:20%;"></div><div class="dijitRuleMark dijitRuleMarkH" style="left:40%;"></div><div class="dijitRuleMark dijitRuleMarkH" style="left:60%;"></div><div class="dijitRuleMark dijitRuleMarkH" style="left:80%;"></div><div class="dijitRuleMark dijitRuleMarkH" style="left:100%;"></div></div><div class="dijitRuleContainer dijitRuleContainerH dijitRuleLabelsContainer dijitRuleLabelsContainerH" id="dijit_form_HorizontalRuleLabels_1" widgetid="dijit_form_HorizontalRuleLabels_1" style="height: 2em; font-size: 75%; color: gray; white-space: nowrap;"><div class="dijitRuleLabelContainer dijitRuleLabelContainerH" style="left:0%;"><div class="dijitRuleLabel dijitRuleLabelH">1</div></div><div class="dijitRuleLabelContainer dijitRuleLabelContainerH" style="left:20%;"><div class="dijitRuleLabel dijitRuleLabelH">20%</div></div><div class="dijitRuleLabelContainer dijitRuleLabelContainerH" style="left:40%;"><div class="dijitRuleLabel dijitRuleLabelH">40%</div></div><div class="dijitRuleLabelContainer dijitRuleLabelContainerH" style="left:60%;"><div class="dijitRuleLabel dijitRuleLabelH">60%</div></div><div class="dijitRuleLabelContainer dijitRuleLabelContainerH" style="left:80%;"><div class="dijitRuleLabel dijitRuleLabelH">80%</div></div><div class="dijitRuleLabelContainer dijitRuleLabelContainerH" style="left:100%;"><div class="dijitRuleLabel dijitRuleLabelH">100%</div></div></div></td><td class="dijitReset" colspan="2"></td></tr>

我又作了这样的尝试：

$(".tsTmp table> tbody tr:eq(2) td:eq(1)");

<td data-dojo-attach-point="containerNode,bottomDecoration" class="dijitReset dijitSliderDecoration dijitSliderDecorationB dijitSliderDecorationH"><div class="dijitRuleContainer dijitRuleContainerH" id="dijit_form_HorizontalRule_1" widgetid="dijit_form_HorizontalRule_1" style="height: 1em; font-size: 75%; color: gray;"><div class="dijitRuleMark dijitRuleMarkH" style="left:0%;"></div><div class="dijitRuleMark dijitRuleMarkH" style="left:20%;"></div><div class="dijitRuleMark dijitRuleMarkH" style="left:40%;"></div><div class="dijitRuleMark dijitRuleMarkH" style="left:60%;"></div><div class="dijitRuleMark dijitRuleMarkH" style="left:80%;"></div><div class="dijitRuleMark dijitRuleMarkH" style="left:100%;"></div></div><div class="dijitRuleContainer dijitRuleContainerH dijitRuleLabelsContainer dijitRuleLabelsContainerH" id="dijit_form_HorizontalRuleLabels_1" widgetid="dijit_form_HorizontalRuleLabels_1" style="height: 2em; font-size: 75%; color: gray; white-space: nowrap;"><div class="dijitRuleLabelContainer dijitRuleLabelContainerH" style="left:0%;"><div class="dijitRuleLabel dijitRuleLabelH">1</div></div><div class="dijitRuleLabelContainer dijitRuleLabelContainerH" style="left:20%;"><div class="dijitRuleLabel dijitRuleLabelH">20%</div></div><div class="dijitRuleLabelContainer dijitRuleLabelContainerH" style="left:40%;"><div class="dijitRuleLabel dijitRuleLabelH">40%</div></div><div class="dijitRuleLabelContainer dijitRuleLabelContainerH" style="left:60%;"><div class="dijitRuleLabel dijitRuleLabelH">60%</div></div><div class="dijitRuleLabelContainer dijitRuleLabelContainerH" style="left:80%;"><div class="dijitRuleLabel dijitRuleLabelH">80%</div></div><div class="dijitRuleLabelContainer dijitRuleLabelContainerH" style="left:100%;"><div class="dijitRuleLabel dijitRuleLabelH">100%</div></div></div></td>

还不够深刻，还须要获取更深的标签才行。

 $(".tsTmp table> tbody tr:eq(2) td:eq(1) div:eq(9)");

<div class="dijitRuleLabel dijitRuleLabelH">0%</div>

至此才获取到了相应的值，那么就能够根据须要修改值了。只要改变index就OK。

 $(".tsTmp table> tbody tr:eq(2) td:eq(1) div:eq(index)");
