I have 5 different forms where I am disabling the submit button when a valid form is submitted so the form can only be submitted once. I am using a hidden field on each form to get the form Id.

function OnSubmit(buttonId) { var disableButton = false; if ($('#formType').val() == 1) { if ($('#CreateEntityName').val() != "" && $('#newAccountGroup').val() != "") { disableButton = true; } } if ($('#formType').val() == 2) { if ($('#newAccount').val() != "" && $('#lastName').val() != "") { disableButton = true; } } if ($('#formType').val() == 3) { if ($('#select2-entityId').val() != 0 && $('#contact').val() != "") { disableButton = true; } } if ($('#formType').val() == 4) { if ($('#select2-entityId').val() != 0 && $('#contact').val() != "" && $('#need').val() != "" && $('#candidates').val() != 0) { disableButton = true; } } if ($('#formType').val() == 5) { if ($('#newAccount').val() != "" && $('#country').val() != "") { disableButton = true; } } if (disableButton == true) { $('#' + buttonId + '').attr("disabled", true); } } 

@Html.Hidden("formType", 5)
