1.通過id控制單個層:
<!DOCTYPE html><html>
<head>
<meta charset="utf-8" />
<title>html邊框虛線演示</title>
<style>
.tabledata{
background: rgba(251, 251, 251, 0.93);
margin: 0; /* 上 右 下 左 */
border:1px solid #F00;
}
.tabledataxuxian{
background: rgba(251, 251, 251, 0.93);
margin: 0; /* 上 右 下 左 */
}
</style>
<script language="javascript">
function show_div(){
var obj_div=document.getElementById("starlist");
obj_div.style.display=(obj_div.style.display=='none')?'block':'none';
}
function hide_div(){
var obj_div=document.getElementById("starlist");
obj_div.style.display=(obj_div.style.display=='none')?'block':'none';
</script>
</head>
<body>
<a href="javascript:hide_div()" >欄位詳情說明</a>
<div id="starlist">
div 內容
</div> </body>
</html>
js 指令碼：
<script language="javascript"> function show_div(){ var obj_div=document.getElementById("starlist"); obj_div.style.display=(obj_div.style.display=='none')?'block':'none'; } function hide_div(){ var obj_div=document.getElementById("starlist"); obj_div.style.display=(obj_div.style.display=='none')?'block':'none'; } </script>
2.通過class控制多個層：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>html邊框虛線演示</title>
<style>
.tabledata{
background: rgba(251, 251, 251, 0.93);
margin: 0; /* 上 右 下 左 */
border:1px solid #F00;
}
.tabledataxuxian{
background: rgba(251, 251, 251, 0.93);
margin: 0; /* 上 右 下 左 */
border:1px dashed #F00;
}
</style>
<script language="javascript">
function show_div(){
var obj_div_s=document.getElementsByClassName("starlist");
for (var i=0,obj_div;obj_div=obj_div_s[i];i++){
obj_div.style.display=(obj_div.style.display=='none')?'block':'none';
}
}
function hide_div(){
var obj_div_s=document.getElementsByClassName("starlist");
for (var i=0,obj_div;obj_div=obj_div_s[i];i++){
obj_div.style.display=(obj_div.style.display=='none')?'block':'none';
}
}
</script>
</head>
<body>
<a href="javascript:hide_div()" >欄位詳情說明</a>
<div class="starlist">
div 內容
</div>
<div class="starlist">
div 內容
</div>
<div class="starlist">
div 內容
</div>
</body>
</html>
js指令碼：
<script language="javascript"> function show_div(){ var obj_div_s=document.getElementsByClassName("starlist"); for (var i=0,obj_div;obj_div=obj_div_s[i];i++){ obj_div.style.display=(obj_div.style.display=='none')?'block':'none'; } } function hide_div(){ var obj_div_s=document.getElementsByClassName("starlist"); for (var i=0,obj_div;obj_div=obj_div_s[i];i++){ obj_div.style.display=(obj_div.style.display=='none')?'block':'none'; } } </script>
