html中按钮的隐藏属性

html中按钮的隐藏属性

我试图在一个按钮上单击显示三个按钮.在按钮单击之前,所有三个按钮都被隐藏.我设置了隐藏属性,我也在点击按钮时调用了一个函数.问题是,当我加载页面时,所有按钮都是可见的.在我添加css之前,它工作得很好.我不明白问题出在哪里.这是HTML代码:

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<link rel="STYLESHEET" type="text/css" href="dba_style/buttons.css" />
<title>Untitled Document</title>

</head>
<script type="text/javascript">
function change(){
document.getElementById("save").hidden = "";
document.getElementById("change").hidden = "";
document.getElementById("cancel").hidden = "";

}
</script>
<body>
<form name="form1" method="post" action="">
<div class="buttons">

    <button class="regular" name="edit" id="edit" onclick="change();">
        <img src="dba_images/textfield_key.png" alt=""/>
        Edit
    </button>

    <button type="submit" class="positive" name="save" id="save" hidden="hidden">

如果您执行以下更改,它也可以在没有jQuery的情况下运行:

添加type="button"到编辑按钮,以便不触发提交表单.
将功能名称更改change()为其他任何名称.
不要使用hidden="hidden",改用CSS : style="display: none;".

以下代码适用于我:

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<link rel="STYLESHEET" type="text/css" href="dba_style/buttons.css" />
<title>Untitled Document</title>
</head>
<script type="text/javascript">
function do_change(){
document.getElementById("save").style.display = "block";
document.getElementById("change").style.display = "block";
document.getElementById("cancel").style.display = "block";
}
</script>
<body>
<form name="form1" method="post" action="">
<div class="buttons">

<button type="button" class="regular" name="edit" id="edit" onclick="do_change(); return false;">
    <img src="dba_images/textfield_key.png" alt=""/>
    Edit
</button>

<button type="submit" class="positive" name="save" id="save" style="display:none;">
    <img src="dba_images/apply2.png" alt=""/>
    Save
</button>

<button class="regular" name="change" id="change" style="display:none;">
    <img src="dba_images/textfield_key.png" alt=""/>
    change
</button>

    <button class="negative" name="cancel" id="cancel" style="display:none;">
        <img src="dba_images/cross.png" alt=""/>
        Cancel
    </button>
