勾选时激活input 否则禁用的javascript代码_表单特效

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:

价格： 特价

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>
