如何使用javascript验证gridview下拉值 [英] How to validate gridview dropdown values using javascript

问题描述

请帮我解决这个问题



我有一个带下拉的网格它填充值如房间号1-5，如果用户选择超过，我有最大占用率占用它应该显示alert.example房间最大占用率2.i有多个用户如果1号房间被2个用户选中，则第3个用户选择意味着它应该验证。

解决方案

< blockquote>如果要在单击保存按钮时进行验证，请编写保存按钮的Javascript代码。循环gridview并检查值并显示验证消息作为摘要。



如果对于每个下拉列表更改，则应编写代码以进行下拉选择更改。

Please help me to fix this

I have a grid with dropdown it populate value As Room No 1-5 and i have maximum occupany if user select more than the occupancy it should show alert.example Room max occupancy 2.i have multiple user if room no 1 got selected by two user then 3rd user select means it should validate.

解决方案

If you want to do validation on click of Save button then write Javascript code for Save button. Loop the gridview and check for the value and show validation message as a summary.

If its for each dropdown change then code should be written for dropdown selection change.
