1、从数据库取数据，进行不同的判断，传给js变量，进而加载页面时，执行不同的JS函数。
<!--
根据数据库存有的身份证信息是否为空，调用修改页面时初始不同的选项。（显示身份证 或者显示护照）
-->
<?php
if($arrMember['idnumber']==''){
$change ='1';
}else{
$change ='2';
}
?>
<script type="text/javascript">
window.onload=function(){
var change="<?php echo $change;?>";
if(change == '1'){
change1();
}
if(change == '2'){
changeidnu();
}
}
</script>
<script>
function changeidnu(){
document.all.mxh2.style.visibility='visible';
document.all.mxh1.style.visibility='hidden';
}
function change1(){
document.all.mxh2.style.visibility='hidden';
document.all.mxh1.style.visibility='visible';
}
</script>
2、下边表单显示部分
<div class="control-group">
<label class="control-label">证件类型: </label>
<?php //echo $change;?>
<?php if($change=='1'){?>
<label class="control-label" style="margin-left:-80px;"><input name="zhengjian" value="1" type=radio onclick="changeidnu()" />身份证件</label>
<label class="control-label " style="margin-left:-30px;"><input name="zhengjian" value="2" type=radio onclick="change1()" checked="checked"/>其他身份证件</label>
<?php }else{?>
<label class="control-label" style="margin-left:-80px;"><input name="zhengjian" value="1" type=radio onclick="changeidnu()" checked="checked"/>身份证件</label>
<label class="control-label " style="margin-left:-30px;"><input name="zhengjian" value="2" type=radio onclick="change1()" />其他身份证件</label>
<?php }?>
</div>
<div class="control-group">
<p>
<div id=mxh2 style="visibility: hidden;margin-left:85px;">身份证件:
<div style="margin-left:75px;margin-top:-25px;"><input type="text" name="idnu" value="<?=$arrMember['idnumber']?>" style="width:200px"/></div>
</div>
</p>
</div>
<div id=mxh1 style="visibility: hidden;margin-left:85px;margin-top:-40px;" >
护照号码: <div style="margin-left:75px;margin-top:-25px;"><input type="text" name="passportnu" value="<?=$arrMember['passportnu']?>" style="width:200px"/></div><br><br>
出生日期: <div style="margin-left:75px;margin-top:-25px;"><input class="Wdate" onClick="WdatePicker()" type="text" name="birthday" style="width:200px" value="<?=$arrMember['birthday']?>" /></div><br><br>
<div style="margin-top:-20px;">性 别:</div>
<?php if($arrMember['gender']=='1'){?>
<label class="radio" style="margin-top:-40px;margin-left:40px;">
<input name="gender" type="radio" value="1" checked="checked" />男
</label>
<label class="radio" style="margin-top:-40px;margin-left:-30px;">
<input name="gender" type="radio" value="0" />女
</label>
<?php }?>
<?php if($arrMember['gender']=='0'){?>
<label class="radio" style="margin-top:-40px;margin-left:40px;">
<input name="gender" type="radio" value="1" />男
</label>
<label class="radio" style="margin-top:-40px;margin-left:-30px;">
<input name="gender" type="radio" value="0" checked="checked"/>女
</label>
<?php }?>
</div>

另一种 可移值性强的代码。
<script language="JavaScript" type="text/JavaScript">
<!--
function showdiv(targetid,objN){
var target=document.getElementById(targetid);
var clicktext=document.getElementById(objN)
if (target.style.display=="block"){
target.style.display="none";
clicktext.innerText="点击查看详细信息";
} else {
target.style.display="block";
clicktext.innerText='关闭详细信息信息';
}
}
-->
</script>
<!--
根据数据库存有的身份证信息是否为空，调用修改页面时初始不同的选项。（显示身份证 或者显示护照）
-->
<?php
if($arrMember['idnumber']==''){
$change ='1';
}else{
$change ='2';
}
?>
<script type="text/javascript">
window.onload = showIDnum;
