C#页面通过JS获取repeater中四个textbox中的数字然后进行求和放在最后一个label里面

Question

请问如何通过JS实现，初步想过有这么几个问题：
1.如何获取repeater中当前行里面所有textbox 的值
2.textbox中数字改变时的事件触发如何设置
3.计算当前行所有值
请各位多多指教JavaScripttextboxC#

Answer 1

1，通过DOM关系获取此行的对象
2，onblur事件
3，通过1得到对象后计算就行了

Answer 3

    function totelChange(o) {
        //              td         tr
        var tr = o.parentNode.parentNode;
        var ipts = tr.getElementsByTagName('input'); //获取此行下的所有输入对象，ipts[0]对应第一个输入框，依次类推
        //计算逻辑和设置相关内容的代码
        alert(123)
    }<input name="repCheckSealing$ctl00$txtBiddingTotel" type="text" value="20" maxlength="10" id="repCheckSealing_ctl00_txtBiddingTotel" class="ticket_right" onblur="totelChange(this)" style="width:80px;" />

Answer 4

更正下，没注意前面还有2个隐藏的控件。。    function totelChange(o) {
        //              td         tr
        var tr = o.parentNode.parentNode;
        var ipts = tr.getElementsByTagName('input'); //获取此行下的所有输入对象，ipts[2]对应第一个输入框，依次类推
        //计算逻辑和设置相关内容的代码
    }

Answer 5

主要问题都已经解决了，还要问一下JS里面想要调用方法totelChange(o)需要传递什么值进去

Answer 6

全都解决了，非常感谢showbo 的帮助！！
