如何使用jquery获取其中包含值的标签的li？ [英] How to get li which has a label with a value inside it with jquery?

问题描述

我的页面中有一个无序列表，每个li里面都有一个名为lbl-colorID的标签，名为RpLblColorID，我在列表外面有一个输入，类名为sel-Color，名为LblSelColor 。现在我想选择具有RpLblColorID的li，其值等于LblSelColor值。如何在jquery中选择它？

I have a unordered list in my page and inside each li I have a label with class name "lbl-colorID" called "RpLblColorID" and I have an input outside the list with class name "sel-Color" called "LblSelColor". Now I want to select the li which has the "RpLblColorID" with the value equal to the "LblSelColor" value. How can I select it in jquery?

 <ul class="thumb-ul">
<asp:DataList runat="server" ID="RptColor" DataSourceID="DSColor" 
RepeatDirection="Horizontal" RepeatLayout="Table" > <ItemTemplate>
                                            <a class="a-pnl-color" href="#">
                                                <li class="thumb-div">

                                                    <div class="col-md-1">
                                                        <asp:label runat="server" ID="RpLblColorID" class="no-display lbl-colorID" Text='<%# DataBinder.Eval(Container.DataItem,"ColorID")%>' />

                                                        <asp:label runat="server" ID="RpLblColorCode"  BackColor='<%# System.Drawing.ColorTranslator.FromHtml(Eval("ColorCode").ToString()) %>'  Width="20px" Height="20px"></asp:label>  
                                                  </div>

                                                    <div class="col-md-2">
                                                        <asp:Label runat="server" ID="RpLblColorName" CssClass="lbl-colorName" Text='<%# DataBinder.Eval(Container.DataItem,"ColorName")%>' ForeColor="Black"></asp:Label>
                                                    </div>
                                                </li>
                                            </a>
                                        </ItemTemplate>
                                    </asp:DataList>
                                </ul>



<input type="hidden" class="sel-color"   runat="server"    id="LblSelColor" name="LblSelColor"    value="0" />

我尝试过：



它不起作用：

What I have tried:

it doesn't work :

$('ul.thumb-ul li :Label.lbl-colorID').filter(function () { return this.Text == $('.sel-color').val.toString() }).attr('class', 'thumb-div-sel');<pre>

推荐答案

（'ul.thumb-ul li：Label.lbl-colorID'）。filter（function（） {return this.Text ==

('ul.thumb-ul li :Label.lbl-colorID').filter(function () { return this.Text ==

（'。sel-color'）。val.toString（）}）。attr（'class'，'thumb-div-sel'）; <预>

('.sel-color').val.toString() }).attr('class', 'thumb-div-sel');<pre>
