使用javascrip的Gridview复选框验证 t
标签:Gridview，Javascript
简介:
您好，在这里，我将说明如何使用JavaScript在gridview中检查复选框的选中状态
说明:
我有一个带有复选框的gridview和一个按钮(如果用户单击按钮)，如果用户没有在gridview中至少选中一个复选框，则需要进行验证，因为我编写了一个JavaScript函数来检查是否在gridview中选中了复选框.
为此，在aspx页面中编写以下代码
< html xmlns ="http://www.w3.org/1999/xhtml">
< head runat ="server">
< title>如果Header复选框选中了，则选中所有复选框</title>
< style type ="text/css">
.Gridview
{
font-family:Verdana;
font-size:10pt;
font-weight:normal;
颜色:黑色；
宽度:500像素；
}
</style>
< script type ="text/javascript" language ="javascript">
函数validateCheckBoxes(){
var isValid = false;
var gridView = document.getElementById(''<％= gvcheckbox.ClientID％>''));
for(var i = 1; i< gridView.rows.length; i ++){
var输入= gridView.rows [i] .getElementsByTagName("input");
if(inputs！= null){
if(inputs [0] .type =="checkbox"){
if(inputs [0] .checked){
isValid = true;
返回true;
}
}
}
}
alert(请至少选择一个复选框");
返回false;
}
</script>
</head>
< body>
< form id ="form1" runat ="server">
Gridview checkbox validation using javascript
Labels: Gridview, Javascript
Introduction:
Hi here I will explain how to check the checked status of checkboxes in gridview using JavaScript
Description:
I have a one gridview with checkboxes and one button if user clicks on button I need to raise validation if user doesn’t checked at least one checkbox in gridview for that I have written one JavaScript function to check whether checkboxes selected in gridview or not.
For that write the following code in aspx page
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>Check all checkboxes if Header checkbox checks</title>
<style type="text/css">
.Gridview
{
font-family:Verdana;
font-size:10pt;
font-weight:normal;
color:black;
width:500px;
}
</style>
<script type="text/javascript" language="javascript">
function validateCheckBoxes() {
var isValid = false;
var gridView = document.getElementById(''<%= gvcheckbox.ClientID %>'');
for (var i = 1; i < gridView.rows.length; i++) {
var inputs = gridView.rows[i].getElementsByTagName(''input'');
if (inputs != null) {
if (inputs[0].type == "checkbox") {
if (inputs[0].checked) {
isValid = true;
return true;
}
}
}
}
alert("Please select atleast one checkbox");
return false;
}
</script>
</head>
<body>
<form id="form1" runat="server">
< asp:gridview id ="gvcheckbox" cssclass ="Gridview" runat ="server" autogeneratecolumns ="False" xmlns:asp =#unknown">
HeaderStyle-BackColor =#7779AF" HeaderStyle-ForeColor ="white">
<列>< asp:templatefield>
< HeaderTemplate>
< asp:checkbox id ="chkheader" runat ="server"/>
</HeaderTemplate>
< itemtemplate>
< asp:checkbox id ="chkchild" runat ="server"/>
< HeaderStyle HorizontalAlign ="Left"/>
< itemstyle horizontalalign ="Left">
< asp:boundfield headertext ="UserName" datafield ="UserName" headerstyle-horizontalalign ="Left"/>
< asp:boundfield headertext ="FirstName" datafield ="FirstName" headerstyle-horizontalalign ="Left"/>
< asp:boundfield headertext ="LastName" datafield ="LastName" headerstyle-horizontalalign ="Left"/>
< asp:button runat ="server" text ="Submit" onclientclick ="javascript:validateCheckBoxes()" xmlns:asp =#unknown"/>
<asp:gridview id="gvcheckbox" cssclass="Gridview" runat="server" autogeneratecolumns="False" xmlns:asp="#unknown">
HeaderStyle-BackColor="#7779AF" HeaderStyle-ForeColor="white">
<columns><asp:templatefield>
<HeaderTemplate>
<asp:checkbox id="chkheader" runat="server" />
</HeaderTemplate>
<itemtemplate>
<asp:checkbox id="chkchild" runat="server" />
<HeaderStyle HorizontalAlign="Left" />
<itemstyle horizontalalign="Left">
<asp:boundfield headertext="UserName" datafield="UserName" headerstyle-horizontalalign="Left" />
<asp:boundfield headertext="FirstName" datafield="FirstName" headerstyle-horizontalalign="Left" />
<asp:boundfield headertext="LastName" datafield="LastName" headerstyle-horizontalalign="Left" />
<asp:button runat="server" text="Submit" onclientclick="javascript:validateCheckBoxes()" xmlns:asp="#unknown" />
</form>
</body>
</html>
