                  问题描述

                  我有以下无线电控制,默认选中为全部".如果用户检查其他单选按钮并提交,则在回发时我想保留选中的按钮,以便用户可以看到他们点击的内容..如何保留使用 jquery 选择的内容?我使用的是:

                  I have the following radiocontrols with Default checked to "All". If user checks some other radio button and submits, on postback i want to retain the checked button, so users can see what they clicked..How do I keep whatever was selected using jquery?? i am using is:

                  <script type="text/javascript" language="javascript">
                   $(document).ready(function() { 
                      var url = 'http://mysite.com/events/Pages/default1.aspx?kwd=';
                      $(".SearchBoxAndChoices a.searchButton").click(function() {
                      var radioVal = $("input[name='EventType']:checked").val();
                      var keywords = encodeURIComponent($(".BasicSearchInputBox").val());  
                      url =url+keywords+"&type="+radioVal;
                      window.location.href=url;  
                      });
                   });
                  </script>                     
                  
                   <div class="EventRadios" style="color:#574319; font:13px Trebuchet">
                      <input type="radio" name="EventType" value="" checked="checked"/>All &nbsp;  
                      <input type="radio" name="EventType" value="Classes" />Class &nbsp;  
                      <input type="radio" name="EventType" value="Events" />Event &nbsp;    
                      <input type="radio" name="EventType" value="Support Groups" />Support Group&nbsp;&nbsp;<br /><br />
                  </div>
                  <input name="KeywordBox" class="BasicSearchInputBox" type="text" value="Keyword Search..."/>
                  <div class="searchBtnHolder"><a class="searchButton" href="#" type="submit"><span>Search</span></a></div>
                  

                  推荐答案

                  这里有一个快速的方法:

                  Here's a quick way:

                  var value = window.location.href.match(/[?&]type=([^&#]+)/) || [];
                  
                  if (value.length == 2) {
                      $('input[name="EventType"][value="' + value[1] + '"]').prop('checked', true);
                  }
