本文章提供一款jquery遍历select教程代码,主要是利用了$("#<%=ddl_xreg_id.clientid%> option").each(function() {形式来each遍历一次,这样所有的select就给查询了一次。<script src="jquery-1.2.1.js" type="text/网页特效"></script><script language="javascript" type="text/javascript">$(document).ready(function(){$("#selecttest").change(function(){ //alert("hello"); //alert($("#selecttest").attr("name")); //$("a").attr("href","xx.html"); //window.location.href="xx.html"; //alert($("#selecttest").val()); alert($("#selecttest option[@selected]").text()); $("#selecttest").attr("value", "2");});});</script><a href="#">aaass</a><!--下拉框--><select id="selecttest" name="selecttest"><option value="1">11</option><option value="2">22</option><option value="3">33</option><option value="4">44</option><option value="5">55</option><option value="6">66</option></select>方法二function autoscrollregion() { var reg_name = $("#<%=txt_reg_name.clientid%>").val(); $("#<%=ddl_xreg_id.clientid%> option").each(function() { if ($(this).text() == reg_name) { $(this).attr("selected", "selected"); break; } }); }
