submit data using Jquery/Javascript during button click

Question

submit data using Jquery/Javascript during button click

Answer 1

Why don't you use the default validation of sharepoint? (Column validation or Form Validation).

it's the easiest and quickest way to achieve that. 

If you really want to use javascript/jQuery, use the "PreSaveAction" function

function presaveaction(){
 if($('.yourDropDown').val() == "")
  return false;
}

when you return false on that function, the form is not saved.

Answer 2

  return false; is not working

Answer 3

Hi,

From your description, my understanding is that you want to restrict edit form with jQuery/JS.

If you want to restrict the default edit form with jQuery/JS, you could refer to these steps below:

1. Enter your editform.aspx.
2. Add below code under <asp:Content ContentPlaceHolderId="PlaceHolderMain" runat="server">.
3. Save this file.

<script src="https://code.jquery.com/jquery-1.11.1.min.js" type="text/javascript"></script>

<script type="text/javascript">
function PreSaveAction(){
 if($("select[id$='DropDownChoice']").val()==""){
  alert("please choose a value!");
  return false;
 }
 return true;
}
</script>

The screenshot below is my result(it will not save data after clicking OK in the message alert):

If you customize your list with InfoPath, you could check the checkbox “Cannot be blank” under Validation section or add a rule for your validation as the screenshot below:

In addition, you could check your code with pressing F12 to debug your code.

Best Regards,

Vincent Han
