Edit Record using Partial View, JQuery and Bootstrap Modal

Question

I have a table on which there's an Edit button for every record at the last column.

My goal is to have an editable form on a modal for the record on which the user pressed the Edit button.

In order to accomplish that, I've created a Partial View which i want to be loaded on the modal, but after tons of tries, i cannot get it working. The JS created to compose the partial view URL and loading into the modal seems to have no effect and it's raising the following error:

VM364 ESa31501901:361 Uncaught ReferenceError: ESa31501901 is not defined at HTMLAnchorElement.onclick

Note: ESa31501901 is the first parameter passed into the JS function.

This is my intention:

a) Edit() : This method will return all records.

b) EditClientFeature(string ClientID, string WorkProcessID) : This method will return a partial view containing the record of a particular client. This method is called when we start editing a client record. The client record is displayed in modal (popup).

c) EditClientFeature(ClientFeatureViewModel model) : This method will update the client record.

ClientFeature ViewModel

public class ClientFeatureViewModel
{
    public string ClientID { get; set; }
    public string WorkProcessID { get; set; }
    public int? Certification { get; set; }
    public bool? TrackingActive { get; set; }
    public string ClientCode { get; set; }
    public string ContractNo { get; set; }
    public string ProductCode { get; set; }
}

{

Answer 1

I think your onclick function parameter value is treated as a variable, not a string.

Solution 1:

Try below to pass as string: (Not tested though!)

onclick="EditCF(\'' + @Model.Piva + '\', \'' + @feature.WorkProcessId+ '\')"

Solution 2:

It's best to Attach a click handler after adding a class for your link. And use HTML5 data attributes for storing your value client side.

<a href="#" class="btn btn-success editClient" data-ClientID="@Model.Piva" data-WorkProcessId="@feature.WorkProcessId"><i class="glyphicon glyphicon-pencil"></i></a> 


$('.editClient).on('click', function() {
    var clientID = $(this).data('ClientID');
    var workProcessId = $(this).data('WorkProcessId');

    var url = "/Admin/EditClientFeature?ClientID=" + clientID 
    + "?WorkProcessID=" + workProcessID;

    $("#ModalBodyDiv").load(url, function () {

      $("#ModalClientFeatures").modal("show");

    })

});

Hope this helps.
