SEO知识:百度登陆框

如何实现如点百度“登陆”时弹出登陆框(网页制作)

如题,谁知道呀。


最方便的实现方式是:

1、在要打开登录框的页面创建一个div,设置div的样式表z-index为本页面最大的,以及设置为居中,调整其大小并将其隐藏;

2、创建一个登录的页面,页面中内容不超过div的大小(也可以部分页面,都写在上一个jsp中,但如果别的页面也需要用就会写很多个了);

3、在有登录按钮的页面,设置登录按钮的事件,点击后弹出div并嵌套登录的页面。

 

下面为示例代码:

login.jsp
<style>
.loginDiv { width: 400px; height: 450px; }
</style>
<center>
<div class="loginDiv">
<from>
    账号:<input type='text' id='name' /><br>
    账号:<input type='password' id='pwd' /><br>
    <button type='submit'>登录</button>
</form>
</center>
</div>
other.jsp
#loginDiv { width: 400px; height: 450px; z-index: 99999; }
<script>
    //jQuery语言
    $(
        $('#loginDiv').hide();
        $('#btnLogin').click(function() {
              $('#loginDiv').dialog({
                width: 400,
                height: 450,
                modal: true,
                resizable: false,
                title: dialogTitle,
                close: function(e, u) {
                    $('#loginDiv').empty();
                    $(this).dialog("destroy");
              });
         });
     );
</script>
<button id='btnLogin' type='button'>登录</button>
<div id='loginDiv'>
    <iframe url='login.jsp></iframe>
    <iframe style="border: 0; width: 100%; height: 100%;"></iframe>
</div>

百度的这种登陆框出现方式怎么做的

div浮动层,参考此例:
<HTML>
<HEAD>
<TITLE>仿windows关机对话框的提示框效果 </TITLE>
</HEAD>
<BODY>
<form action="#">
<input name=btn1 type=button value=有自定义按钮 onclick=showalert1();>
<input name=btn2 type=button value=无自定义按钮 onclick=showalert2();>
</form>
<script language="javascript">
<!--
function gourl(e){
switch(e){
case 1:
window.alert("点击了确定按钮.");
break;
case 2:
break;
case 3:
window.alert("点击了其它按钮.");
break;
default:
break;
}
}
function showalert1(){
var Br = new innerMessageBox();
Br.ShowModal("带第三个按钮的示例", "您确定要删除该项吗?", 320, 120, "gourl($)", "重试");
}
function showalert2(){
var Br = new innerMessageBox();
Br.ShowModal("默认两个按钮的示例", "您确定要删除该项吗?", 320, 120, "gourl($)");
}
