在gridview中的复选框之间切换复选框.

本文介绍了在gridview中的复选框之间切换复选框.的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

1.我有一个带有2个复选框列和一个文本框列的模板字段的网格视图. 我需要JavaScript来切换复选框中的检查状态(即，我有2个名称为chkapprove和chkreject的复选框，如果我选中"chkapprove"，则"chkreject"应取消选中它是否已被选中，反之亦然) 2.我需要在chkreject检查，并没有什么在文本框中输入其具有与味精进入理性"警报按钮点击功能..

1. i have a grid view with template fields with 2 checkbox column and a textbox column. i need javascript to toggle the check status in the checkboxes(i.e i hav 2 checkbox with name chkapprove and chkreject, if i check "chkapprove" then "chkreject" should uncheck if it is already checked and vice versa) 2. i need a button click function which has to alert with msg "Enter the reason" when chkreject is checked and nothing is entered in the text box..

function reason() { MyGridView = document.getElementById('<%= grdaccess.ClientID %>'); var Inputs = MyGridView.getElementsByTagName("input"); var chkBox = "Chkreject"; var textbox = "txtreason"; for (var n = 0; n < Inputs.length; ++n) if (Inputs[n].type == 'checkbox' && Inputs[n].id.indexOf(chkBox, 0) >= 0 && Inputs[n].checked) if (Inputs[n+1].type == 'textbox' && Inputs[n+1].id.indexOf(textbox, 0) >= 0 && Inputs[n+1].length <= 0) { alert("enter the reason"); return false; } return true; }

<asp:Button ID="btnSubmit" runat="server" CssClass="showall" Text="Submit" OnClientClick="javascript:return reason();" onclick="btnsubmit_Click" />

推荐答案

尝试使用输入[n + 1] .type =="text" Try to use Inputs[n+1].type == ''text''
