Currently, I am working on incorporating the selected index text from a DropDownList into a JavaScript string. My approach involves storing the text in a hidden field and retrieving it through C# to ensure the JavaScript variable retains its value even after the page reloads.
I would appreciate any suggestions on whether using hidden fields is the correct method for this task, as well as guidance on how to set the hidden field value as a JavaScript variable.
<asp:DropDownList runat="server" ID="dropCallbackReason" SelectedIndexChanged="riskSeverityDropDown_SelectedIndexChanged" onChange="javascript:updateCallBackReason()" ClientIDMode="Static" >
<asp:ListItem Text="-- Select Reason --" Value="1"></asp:ListItem>
<asp:ListItem Text="Booking" Value="6"></asp:ListItem>
<asp:ListItem Text="Discussing" Value="11"></asp:ListItem>
<asp:ListItem Text="Contract" Value="45"></asp:ListItem>
</asp:DropDownList>
<asp:HiddenField id="ValueHiddenField" value="" runat="server"/>
<script type="text/javascript">
function updateCallBackReason() {
var ddlReason = document.getElementById("<%=dropCallbackReason.ClientID%>");
callBackReasonPreString = ddlReason.options[ddlReason.selectedIndex].text;
callBackReason = callBackReasonPreString.replace(/ /g, '');
return callBackReason;
}
$(document).ready(function () { updateCallBackReason() });
</script>
Thank you in advance for your help,
