The following javascript will validate that atleast one checkbox is checked in a checkboxlist . And if a checkbox named 'other' is checked , it will check that a textbox that is next to it is not empty .


<br /><script language="javascript"><br /> function ValidateCheckboxList(){<br /> try{<br /> var oCheckBoxList = document.getElementById("chkbxLstSample");<br /> var table = oCheckBoxList.childNodes[0];<br /> var checkedCount = 0;<br /> var otherChecked = false;<br /> for (var i=0;i<table.childnodes.length; td =" table.childNodes[i].childNodes[0];" chekbox =" td.childNodes[0];" label =" td.childNodes[1];" checkedcount =" checkedCount+1;" innertext ="=" otherchecked =" true;">0)){<br /> var oTextBox = document.getElementById("txtCheck");<br /> if(oTextBox.value == ""){<br /> alert("Enter Text");<br /> oTextBox.focus();<br /> return false;<br /> }<br /> <br /> }else if(checkedCount==0){<br /> alert("Check at least one");<br /> return false;<br /> }<br /> return true;<br /> }catch(e){<br /> alert(e.description);<br /> }<br /> <br /> }<br /> </script><br /><br /><br /><form id="form1" runat="server"><br /><div><br /> <table><br /><tbody><tr><br /><td style="WIDTH: 100px"><br /><?xml:namespace prefix = asp /><asp:checkboxlist id="chkbxLstSample" runat="server"><br /><asp:listitem>1</asp:listitem><br /><asp:listitem>2</asp:listitem><br /><asp:listitem>3</asp:listitem><br /><asp:listitem>Other</asp:listitem><br /></asp:checkboxlist></td><br /><td style="WIDTH: 100px"><br /><asp:button id="btnTest" runat="server" text="Test"></asp:button><br /><asp:textbox id="txtCheck" runat="server"></asp:textbox></td><br /></tr><br /></tbody></table><br /><br /></div><br /></form><br />
