Question

我想在此网站上添加一些信息“http://diyanet.gov.tr/tr/namazvakitleri”。在这个网站上有一个选择选项菜单，数据与更多选择菜单相关。

我的意思是，如果有人选择了选择菜单id=State而选择了选择菜单id=City，则会显示相关信息。示例Html代码如下。当州和城市选择时，最后的信息出现了。我想在我的应用中使用div selected option value of state的数据之后选择selected option value of city而不是class=vakitler。但是我无法正确地从这个网站获取这些数据。任何人都可以帮助我。

<DIV id="stateHtml">
<SELECT name="State" id="State" style="width: 113px;"><OPTION value="">Seciniz</OPTION> 
<OPTION value="500">ADANA</OPTION> 
<OPTION value="501">ADIYAMAN</OPTION> 
<OPTION value="502">AFYON</OPTION> 
<OPTION value="503">AĞRI</OPTION> 
<OPTION value="504">AKSARAY</OPTION>
<OPTION value="505">AMASYA</OPTION> 
<OPTION selected="selected" value="506">ANKARA</OPTION> 
<OPTION value="507">ANTALYA</OPTION>

<SELECT name="City" id="City" style="width: 113px;">
<OPTION value="">Seciniz</OPTION> 
<OPTION value="9205">AKYURT</OPTION> 
<OPTION selected="selected" value="9206">ANKARA</OPTION> 
<OPTION value="9207">AYAŞ</OPTION> 
<OPTION value="9208">BALA</OPTION> 
<OPTION value="9209">BEYPAZARI</OPTION> 
</SELECT></DIV>

<DIV class="vakitler">
<DIV id="liImsak"><SPAN>İmsak</SPAN><SPAN id="spImsak">03:41</SPAN></DIV>
<DIV id="liGunes"><SPAN>Güneş</SPAN><SPAN id="spGunes">05:30</SPAN></DIV>
<DIV id="liOgle"><SPAN>Öğle</SPAN><SPAN id="spOgle">13:02</SPAN></DIV>
<DIV id="liIkindi"><SPAN>İkindi</SPAN><SPAN id="spIkindi">16:55</SPAN></DIV>
<DIV id="liAksam"><SPAN>Akşam</SPAN><SPAN id="spAksam">20:22</SPAN></DIV>
<DIV id="liYatsi"><SPAN>Yatsı</SPAN><SPAN id="spYatsi">22:02</SPAN></DIV>
