Answer 2

我想问下 如何 在 这些 textbox 得到回车按键后，对textbox总的输入进行判断，并将这些自动生成的textbox的值 进行累加，将值回写到textbox ID = Tlbsum 的 这个textbox中。我原本是想写在 function CheckInput(val,id) {} 这里的 可 只要写入  float tlb_sum= 0.00f; 这句 整个页面就消失了 而不是 跳到下一个textbox框，注释掉 只留下 event.keyCode = 9; 就没问题  求教了 谢谢 

Answer 3

谢谢 楼上的回答 ，我的累加是在用户修改textbox的值并按回车后，重新对自动生成的所有的textbox进行累加，并将结果放入一个特定的texbox中，如何遍历，我知道如何改 ，可就是不知道咋调用，写入那个事件中， 试过正则表达式，onblur 事件 都不能实现 所有 发帖求方法！
