一、复选框设置参数

html代码如下：

<div class="flsm_btns">

         <input type="hidden" name="agreeFlagValue" id="agreeFlagValue"          value="${copyRight.agreeFlag}"/>         <input type="checkbox" name="agreeFlag" id="agreeFlag" />      <span>       <a id="low-declare" target="_blank" href="${pageContext.request.contextPath}/web/law">       我已阅读酷漫网相关法律声明       </a>      </span>     </div>

$(function(){

      var agreeFlagValue = $("#agreeFlagValue").attr("value");

      if(agreeFlagValue != "" && agreeFlagValue == "1") {           $("#agreeFlag").attr("checked",true);      } else {           $("#agreeFlag").attr("checked",false);      }

});

获取checkbox的值，并判断

console.log(document.getElementById("agreeFlag").checked);

 var agreeFlag = (document.getElementById("agreeFlag").checked == true) ? 1 : 0; if(agreeFlag == 0) {      lock = false;     alert("对不起，您得先同意酷漫网相关法律声明才可以发布版权信息!");     $("#low-declare").css("color","red"); } else {   lock = true;  $("#low-declare").css("color","#2d3e53"); } 

二、设置radio的参数值

html代码如下：

<div class="upl">

      <div class="uplena">信息有效期限：</div>      <div class="upricon mt10">          <input type="hidden" name="termOfValidityValue" id="termOfValidityValue"           value="${copyRight.termOfValidity}"/>       <div class="checkbox">        <input type="radio" name="termOfValidity" value="14天"/><span>14天</span>       </div>       <div class="checkbox">        <input type="radio" name="termOfValidity" value="一个月"/><span>一个月</span>       </div>       <div class="checkbox">        <input type="radio" name="termOfValidity" value="无限期"/><span>无限期</span>       </div>      </div>     </div>

$(function(){   

     var termOfValidityValue = $("#termOfValidityValue").attr("value");     if(termOfValidityValue != "") {          $("input[name='termOfValidity'][value='" + termOfValidityValue + "']").attr("checked","checked");     } else {          $("input[name='termOfValidity'][value!='" + termOfValidityValue + "']").removeAttr("checked");     }

});

获取radio的选中值：

/* 本信息有效期限 */

 var termOfValidity = $('input[name="termOfValidity"]:checked').val();

三、获取selected的值

设置选中状态：

$("#filter_item_con select option:first").attr("selected","selected");

获取选中值：

var selectedCity = $("#filter_item_con #city option:selected").attr("value");
