2.好友信息
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>无标题文档</title> <script src="jquery-1.11.2.min.js"></script> <style type="text/css"> /*auto 随机*/ *{ margin:0px auto; padding:0px} #list{ width:150px; height:100px;} .user{ width:150px; height:26; background-color:#3FC; margin-top:2px; color:#F00; text-align:center; line-height:26px; vertical-align:middle;} .user:hover{ cursor:pointer;} </style> </head> <body> <h1>好友信息</h1> <?php $uid="zhaoyi"; include("dbda.class.php"); $db=new dbda(); $sql="select firend from firend where me=‘{$uid}‘"; $attr=$db->Query($sql); ?> <div id="list"> <?php foreach($attr as $v) { $fuid=$v[0];//好友用户名 $sqlname="select name from users where uid=‘{$v[0]}‘"; $aname=$db->Query($sqlname); $fname=$aname[0][0];//好友的姓名 echo"<div class=‘user‘ bs=‘{$fuid}‘>{$fname}</div>"; } ?> </div> <script type="text/javascript"> $(document).ready(function(e) { //点击选中的事件 $(".user").click(function(){ //清除选中项 $(".user").css("background-color","#3FC"); $(".user").attr("xz","0"); //让该项选中 $(this).css("background-color","#CF3"); //加一个选中属性 $(this).attr("xz","1"); alert($(this).attr("bs")); }) //鼠标放上事件 $(".user").mouseenter(function(){ $(this).css("background-color","#CF3"); }) //鼠标离开事件 $(".user").mouseout(function(){ if($(this).attr("xz")!="1") { $(this).css("background-color","#3FC"); } }) }); </script> </body> </html>
3.通过输入信息使数据框变色
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>无标题文档</title>
<script src="jquery-1.11.2.min.js"></script>
</head>
<body>
<div>
<input type="text" class="txt" />
<input type="text" class="txt" />
<input type="text" class="txt" />
<input type="text" class="txt" />
</div>
</body>
<script type="text/javascript">
$(document).ready(function(e) {
//.blur() 失去焦点时触发 .focus() 获得焦点时触发
$(".txt").blur(function(){
//.trim() 去空格
if($(this).val().trim())
{
$(this).css("background-color","#FFF");
}else
{
$(this).css("background-color","red");
}
})
});
</script>
</html>
4.通过单项添加和全部添加实现信息转移
