input.text
{
font-size: 12px;
border-width: 1px;
border-color: #AAAAAA;
border-style: solid;
height: 21px;
}
input.readonly
{
border-width: 1px;
border-color: #AAAAAA;
border-style: solid;
height: 21px;
background-color: #EEEFED;
}
span.readonly
{
font-size: 12px;
border:1px;
border-color: #AAAAAA;
border-style: solid;
height: 21px;
background-color: #EEEFED;
}
</style>
<script language= "JavaScript ">
function protectElement(element)
{
var element = document.getElementById(element);
if (element.type == "text ")
{
element.className = "readonly ";
}
}
function unProtectElement(element)
{
var element = document.getElementById(element);
if (element.type == "text ")
{
element.className = " ";
}
}
function checkboxOnclick()
{
if(document.getElementById( "cc ").checked == true)
{
unProtectElement( "aa ");
}
else
{
protectElement( "aa ");
}
}
</script>

<body>
<form>
<input type= "text " class= "readonly " style= "width:70px; " value= "20000 " id= "aa "/>
<input type= "checkbox " name= "cc " id= "cc " onClick= "checkboxOnclick(); "/>
<span class= "readonly " style= "width:172px "> 20000 </span>
</form>
</body>
</html>
[/code]
问题:
1 点checkbox时候, input 只需要变背景色的,为什么高度和长度会变?
2 “font-size” 对于input 和 span 是不是不同的标准? 为什么设置同样的size,一个字体大一个字体小?
------解决方案--------------------
样式没写好。
