I have a cshtml page with this code:
<form action='@Url.Action("ExportExcel", "Records")' method="post" target="_blank" onsubmit="return exportExcel(), true">
<input type="hidden" name="filteredRecordsIds" id="filteredRecordsIds" value="" />
<input id="btnExportExcel" type="submit" hidden="hidden" />
</form>
in js the exportExcel function:
function exportExcel() {
$('#filteredRecordsIds').val(filteredRecords.map(function (record) { return record.Id }));
return true;
}
in controller Records:
public ActionResult ExportExcel(string filteredRecordsIds)
{...}
I would like to add modal/popup, before the submitting that ask the user:
"Would you like to export with calculations?" with 2 buttons options: "Yes" or "No".
Depending on the user's response, I would like to send the answer to the controller (as second parameter).
How can I add that?
Thank You!
You can try to remove onsubmit,and use a button to open modal,then calling exportExcel when clicking Yes button:
<form action='@Url.Action("ExportExcel", "Records")' method="post" target="_blank" id="myForm">
<input type="hidden" name="filteredRecordsIds" id="filteredRecordsIds" value="" />
<input id="btnExportExcel" type="button" value="submit" data-toggle="modal" data-target="#exampleModalLong"/>
</form>
<!-- Modal -->
<div class="modal fade" id="exampleModalLong" tabindex="-1" role="dialog" aria-labelledby="exampleModalLongTitle" aria-hidden="true">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="exampleModalLongTitle">Modal title</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
Would you like to export with calculations?
</div>
<div class="modal-footer">
<button type="button" class="btn btn-primary" onclick="exportExcel()">Yes</button>
<button type="button" class="btn btn-secondary" data-dismiss="modal">No</button>
</div>
</div>
</div>
</div>
js(submit the form in exportExcel):
function exportExcel() {
$('#filteredRecordsIds').val(filteredRecords.map(function (record) { return record.Id }));
$("#myForm").submit();
}
