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");
