Question

Is there a way to ensure my chat view functions properly without relying on partial views?

I am currently working on integrating a private chat feature using SignalR in my project, and I have encountered an issue while creating a View with accessible model values to pass to the server. Specifically, I have a list of doctors, and when a user clicks on a doctor's link, it should open a chat partial view for consultation. However, I am facing difficulties in utilizing the model's values from the partial view in the parent view's JavaScript code. Although there are suggestions on how to retrieve data from a partial view on Stack Overflow, I have also attempted to write JavaScript within the partial view using @section, but this approach is not permitted. As a solution, I am considering combining both models into one and using it in the parent view. For instance, when I click on a doctor's name, I want to update the values in the chatbox specific to that doctor and use those values in the JavaScript for chatting. Here is some of my Parent View code:

@model E_HealthCare_Web.ViewModels.ConsultationViewModel

<section class="chat-wrapper">
    <!-- Code for doctor list goes here -->
</section>
<section class="chatbox-section">
    <!-- Chatbox section code goes here -->
</section>

Below is the partial view where I'm trying to access the model values:

@model E_HealthCare_Web.ViewModels.ChatLoadViewModel

<!-- Partial view content here -->

Lastly, here is the JavaScript responsible for the chat functionality:

 // JavaScript code for chat functionality goes here

Additionally, below are some controller methods and model classes used in this implementation:

//Controller methods and model classes code goes here

If anyone has suggestions or guidance on how to improve this implementation, please feel free to share your insights. Thank you!

Utilizing session data can be beneficial as it allows for the storage of information needed across multiple actions/views. Keep in mind that session data is stored on the server, so if you intend to access it from JavaScript, an Ajax request will be necessary. (Are you planning to use the data passed from a partial view in JS? Or is there some confusion here?)

To implement this, create two actions within your Home controller: one to add data to the session and another to retrieve the saved data.

public IActionResult SetChatData(object data)
{            
    Session["chatData"] = data;
    return Json(data);
}

public IActionResult GetChatData()
{
    return Json(Session["chatData"]);
}

You can now utilize these methods to write or retrieve data from the session by sending an Ajax request:

// This function should return the provided data parameter
function setChatData(data) {
    var result;

    $.ajax({
        url: "/Home/SetChatData",
        type: 'POST',
        dataType: 'json',
        data: JSON.stringify({ data: data }),
        contentType: 'application/json; charset=utf-8',
        async: false
    }).done(function(data) {
        result = data;
    });

    return result;
}

The following request fetches data:

function getChatData() {
    var result;

    $.ajax({
        url: "/Home/GetChatData",
        type: 'GET',
        contentType: 'application/json; charset=utf-8',
        async: false
    }).done(function(data) {
        result = data;
    });

    return result;
}
