AngularJs cope undefined issue while adding a partial view through fetch api.

I am migrating some of my old views into new mvc core 6 views.

Can I use angularjs in .net 6 ?

If so then guide me

My old views were using below plugin and I am using jquery V3.5.1.

If I remove angularjs logic from my views then I 'll have to re-write the logic which would be based in jquery and razor view.

It will increase my development time and due to the lack of time, I want to use the angularjs logic as same.

Previously, This view contained the combined jquery and angularjs controller logic.

But now there is a bit different with new logic, I am now calling through fetch api to load the partial view.

and this is the major cause of issue. Now angularjs is not working as expected.

See my below code

<div id="FindBranchPage">  

and the loading mechanism is as follow

const loadFindBranch = async (data) => {  
    const settingsFindBranch = {  
        method: "POST",  
        headers: {  
            "Content-Type": "application/json"  
        body: JSON.stringify(data)  
    //affixScriptToBody("/lib/apis/vehiclelistctrl.js", function () { alert("The script \"vehiclelistctrl.js\" has been correctly loaded."); })  
    const responseFindBranch = await fetch(REACT_APP_FINDBRANCH, settingsFindBranch);  
    if (responseFindBranch && !responseFindBranch.ok) {  
        resultPages = [];  
    else {  
        resultPages = await responseFindBranch.text();  
        document.querySelector('#FindBranchPage').innerHTML = resultPages;  
        if (angular.element(document.getElementById('divIdFrmCarData')).scope()) {  
        /* let vhscriptElement = document.createElement("script");  
        vhscriptElement.src = "/lib/apis/vehiclelistjs.js";  
        //vhscriptElement.async = true;  
        document.body.appendChild(vhscriptElement); */                           

and this is the controller action

public IActionResult FindBranch(/*int franchiseId = 0*/[FromBody] BookingVM model)  
            int franchiseId = model != null && model.HomeSearch != null &&   
                model.HomeSearch.FranchiseId.HasValue ? model.HomeSearch.FranchiseId.Value:0;  
            ViewBag.SrvDtTime = DateTime.Now.ToString("MM/dd/yyyy HH:mm");  
            ViewBag.Booking = lObjBooking;          
            ViewBag.FranchiseId = franchiseId;           
            return PartialView(model);  

and this is the FindBranch.cshtml

@using System  
@model BookingVM;  
@using Microsoft.Extensions.Configuration  
@using CarRentalWidget.BLL.Services  
@using System.Net.Http  
@using System.Text.Json  
@inject IConfiguration Configuration  
     BookingVM? bd = Model;

                        $scope.loading = false;  

Now this line is the issue ,

  document.querySelector('#FindBranchPage').innerHTML = resultPages;    

after assigning in FindBranchPage div, Angular and jquery have stopped working.

and if somehow , I try to create a js plugin in parent view then


It always returned undefined.

    net 6 is the server side. it has no effect on client javascript code support.

    I use react instead of angular, and don't know why you are not using angular components instead of partial views.

    anyway, it looks like you replaced jQuery .html() with set innerHTML. jQuery has support to run the javascript in the html fragment, but the native innerHTML does not.
