我试图在一个按钮上显示三个按钮。在按钮之前，所有三个按钮都被隐藏。我设置隐藏的属性，我也在一个按钮点击调用一个功能。问题是，当我加载页面时，所有按钮都可见。在我添加css之前，它工作得很好，我不明白问题所在。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"> <img src="dba_images/apply2.png" alt=""/> Save </button> <button class="regular" name="change" hidden="hidden" id="change"> <img src="dba_images/textfield_key.png" alt=""/> change </button> <button class="negative" name="cancel" id="cancel" hidden="hidden"> <img src="dba_images/cross.png" alt=""/> Cancel </button> </div> </form> </body> </html>
这里是我正在使用的CSS。
.buttons a,.buttons button{
display:block;
float:left;
margin:0 7px 0 0;
background-color:#f5f5f5;
border:1px solid #dedede;

padding:5px 10px 6px 7px; /* Links */
}
.buttons button{

}
.buttons a.positive:active{
background-color:#529214;
border:1px solid #529214;
color:#fff;
}
/* NEGATIVE */
.buttons a.negative,button.negative{
color:#d12f19;
}
.buttons a.negative:hover,button.negative:hover{
background:#fbe3e4;
border:1px solid #fbc2c4;
color:#d12f19;
}
.buttons a.negative:active{
background-color:#d12f19;
border:1px solid #d12f19;
color:#fff;
}
/* REGULAR */
button.regular,.buttons a.regular{
color:#336699;
}
.buttons a.regular:hover,button.regular:hover{
background-color:#dff4ff;
border:1px solid #c2e1ef;
color:#336699;
}
.buttons a.regular:active{
background-color:#6299c5;
border:1px solid #6299c5;
color:#fff;
}
我可以做什么改变，以便当我点击编辑它设置三个按钮的隐藏属性false。提前致谢。

如果您进行以下更改，它也可以不使用jQuery：
>将type =“button”添加到编辑按钮，以不触发提交表单。
>将change()函数的名称更改为其他任何东西。
>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> </div> </form> </body> </html>
