我希望点击“updqte”按钮后按钮变成“save”,然后单元格变成文本框,编辑完文本框后点击“save”结果提交给了数据库。按钮改变用js做完了,其他的实在是不回了,各位大神帮帮忙吧。

2.用ajax 提交参数到后台,调用php程序
3.然后将接收内容提交到数据库
4.成功or失败返回到页面

我表上红色的部分是一个数组,我想让这个数组变成动态的,要不然所有按钮都只操作一条数据。有什么好办法没?
一个.show()
一个.hide()
当点击完一个操作就触发函数转换到另一个按钮
搭配ajax 足够完成大量input提交工作

第24行的那个数组能不能改成动态的,要不然所有按钮都只操作同一条数据,应该怎么改啊?
<head>
<script type="text/javascript" src="/jquery/jquery.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$(".btn1").click(function(){
$(".btn1").hide();
$(".btn2").show();
});
$(".btn2").click(function(){
$(".btn1").show();
$(".btn2").hide();
});
});
</script>
</head>
<body><button class="btn1" style="display:none">update</button>
<button class="btn2">save</button>
</body>
</html>
刚才描述的不是很清楚 写了个测试的代码 你可以参考
好固执的孩纸啊
{ //可以传递个当前对象过来
var tds = document.getElementsByTagName("td");
var t1 = document.getElementById("a").innerHTML;
var txt = document.createElement("input");
txt.type = "text";
txt.value = t1;
txt.id = "sort_t";
obj.parentNode.childNodes[1].appendChild(txt); //添加至第二个td,可根据需要修改
txt.select();
}调用时,
change(this)
还有你的id命名重复了,这样只能获取第一个
