首页 / 脚本样式 / JavaScript / 勾选时激活input 否则禁用的javascript代码

复制代码 代码如下:
window.onload = function（）{
var price = document.getElementById（"price"）;
price.disabled = true;
price.style.padding = "2px 3px";
price.style.background = "#eee";
price.style.border = "1px solid #ccc";
var tj = document.getElementById（"tj"）;
tj.onclick = function（）{
if（tj.checked == true）{ //可编辑
price.disabled = false;
price.style.background = "#fff";
price.style.border = "2px solid #ff7d00";
price.style.padding = "2px 3px";
price.focus（）;

} else {
price.disabled = true;
price.style.background = "#eee";
price.style.border = "1px solid #ccc";
price.style.padding = "2px 3px";
}
}

}

复制代码 代码如下:
<form action="#">
价格：<input id="price" type="text"> <input id="tj" hidefocus=true type="checkbox">特价
</form>

唯一的可去之外是加了一点美化，使用户体验更加一层楼，其中包括边框的加粗，焦点的获取，checkbox边框线的隐藏等等。
测试代码
<script type="text/javascript"> window.onload = function（）{ var price = document.getElementById（"price"）; price.disabled = true; price.style.padding = "2px 3px"; price.style.background = "#eee"; price.style.border = "1px solid #ccc"; var tj = document.getElementById（"tj"）; tj.onclick = function（）{ if（tj.checked == true）{ //可编辑 price.disabled = false; price.style.background = "#fff"; price.style.border = "2px solid #ff7d00"; price.style.padding = "2px 3px"; price.focus（）; } else { price.disabled = true; price.style.background = "#eee"; price.style.border = "1px solid #ccc"; price.style.padding = "2px 3px"; } } } </script> <form action="#"> 价格：<input id="price" type="text"> <input id="tj" hidefocus=true type="checkbox">特价 </form>
