function ResendEmailInvite(internalUserId, familyMemberId) {
theinternalUserId = internalUserId;
theFamilyMemberId = familyMemberId;
if(confirm('Are you sure you want to resend this family member's invite?')){
$.ajax({
type: "POST",
url:"/Admin/ResendFamilyMemberEmail",
data: {internalUserId : theinternalUserId, familyMemberId : theFamilyMemberId},
success: function(response){
alert(response);
},
error: function(){
alert("Error");
}
});
return false;
}
}
I am using ASP.net MVC 3.
This is an ajax/javascript method in my view.
As far as the syntax goes, is this correct?
The familyMemberId is going to be dynamic, however, the userId is not.
I want to pass the userId from my viewModel to this ajax call, how can I do this?
What you're wanting to do is get the data from the model in your controller into the view. This is what MVC is all about. From the MSDN MVC 4 Tutorial:
Controller:
You can define your model using the VS menu system and the Entity Framework so you're actually accessing the database.
public class YourController : Controller
{
private YourDBContext db = new YourDBContext();
public ActionResult YourAction(int user_id = 0)
{
User user = db.Users.find(user_id);
if(user == null) {
return HttpNotFound(); // Or unauthorized or whatever
}
return View(user);
}
//...
View:
#Model IEnumerable<MvcUser.Models.User>
<!-- other stuff -->
<script type="text/javascript>
// the rest of your script
function ResendEmailInvite(internalUserId, familyMemberId) {
theinternalUserId = #Model.userId;
theFamilyMemberId = familyMemberId;
if(confirm('Are you sure you want to resend this family member's invite?')){
$.ajax({
type: "POST",
url:"/Admin/ResendFamilyMemberEmail",
data: {internalUserId : theinternalUserId, familyMemberId : theFamilyMemberId},
success: function(response){
alert(response);
},
error: function(){
alert("Error");
}
});
return false;
}
}
This works because, as you pointed out, the userId is not dynamic after the page has loaded. You would need to create some other hook in your HTML for javascript to grab if you wanted really dynamic behavior.

I have a dropdown list in a blade view. I want to send the value of the selected item to the controller immediately onchange. I have 2 routes in web.php:
Route::get('/plots', 'PlotController#index');
Route::get('/plots/{testId}', 'PlotController#getData');
The first one populates the dropdown list. The second one is supposed send the value of the dropdown list to the controller, which pulls stuff from mysql and sends the data back to the view, which draws a chart. I can get the dropdown to populate ok, but I can't figure out how to send the selected value to the controller. I'm trying to use ajax to do it like this:
$(document).ready(function() {
$('#sel_test').change(function() {
var testId = $(this).val();
console.log("testId=" + testId);
$.ajax({
url: 'plots/' + testId,
type: 'get',
dataType: 'json',
success: function(response) {
console.log("success");
}
});
});
});
The testId output to the console is correct but it never makes it to the controller. The error I see in the console is:
GET http://homestead.test/plots/1 500 (Internal Server Error)
I'm pretty new to laravel and find it extremely confusing. Can anyone explain the correct way to do this?
EDIT:
After testing and confirming Rian's answer as correct, I then tried to implement the real code, which of course is much more complicated. Instead of the controller returning the input test_id:
return $request->test_id;
It actually returns a more complex structure:
return view('plot')
->with('measurements',json_encode($result))
->with('events',json_encode($timeline))
->with('limits',json_encode($limits));
When I uncomment the original controller code, including the return section above, it seems to affect the ability of the controller to return anything at all. Here is the first few lines of the PlotController getData method:
public function getData(Request $request) {
Log::debug("made it to PlotController.php#getData");
Log::debug("test_id="+$request->testId);
And here is the log output:
[2020-02-23 16:43:52] laravel.DEBUG: made it to
PlotController.php#getData
The second line does not output anything. Here is what I see in the javascript console after I select an item from the dropdown list:
testId=49 jquery.min.js:2 GET
http://homestead.test/get-data-by-id?test_id=49 500 (Internal Server
Error)
Any ideas?
The easiest way is to get the data in Laravel Request. At least that's how I do it.
So your route shouldn't contain any parameter for that.
Your route will look like this:
Route::get('get-data-by-id', 'PlotController#getData')->name('get.data.by.id');
Your ajax should be like this:
$(document).on('change', '#sel_test',function(){
var testId = $(this).val();
$.ajax({
type:'GET',
url:"{{ route('get.data.by.id') }}",
data:{'test_id':testId},
success:function(data){
console.log(data);
}
});
});
In your controller's getData() function just use Laravel Request to fetch the data.
public function getData(Request $request)
{
// You can return the ID to see if the ajax is working
return $request->test_id;
}
Make it post from Get for easier
At Web.php
Route::post('/list/plots', 'PlotController#getData')->name('getData');
At Blade file Ajax Request :
$(document).ready(function() {
$('#sel_test').change(function() {
var testId = $(this).val();
var url = '{{ route("getData")}}';
var token = "{{ csrf_token()}}";
$.ajax({
method:"post",
url: url,
data:{testId:testId,_token:token}
dataType: 'json',
success: function(response) {
console.log("success",response);
}
});
});
});
At Controller :
public function getData(Request $request){
$testId = $request->testId;
// Write your logic here
}
Try this. Hopefully work for you
I have to perform following operation.
On a button click from View1, do Ajax request and get complex object as return.
Pass this object to View2 as parameter.
Process the data sent from view1 in client side(inside $(window).load()).
Below is my code:
View1 :
var Url = baseUrl() + "/InteractiveReport/GetRatingProfitData/";
$.ajax({
type: "POST",
url: Url,
contentType: "application/json; charset=utf-8",
dataType: "html",
// dataType: "json",
data: JSON.stringify({ "Projects": SelectedProjectinfo }),
success: function (JsonData) {
debugger;
var w = window.open('about:blank');
w.document.open();
w.document.write(JsonData);
w.document.close();
},
error: function (retVal) {
alert("error:" + retVal.responseText);
}
});
InteractiveReportController :
public ActionResult RatingProfitReport(ProfitRatingInfoModel RatingProfitData)
{
return View("RatingProfitReport", RatingProfitData);
}
public ActionResult GetRatingProfitData(IRSelectedProjectInfoModel Projects)
{
ProfitRatingInfoModel RatingProfitData = new ProfitRatingInfoModel();
//GET RatingProfitData from Database
return RatingProfitReport(RatingProfitDataMdl);
//var jsonSerializer = new JavaScriptSerializer();
//string response = jsonSerializer.Serialize(RatingProfitDataMdl);
//return Json(response, JsonRequestBehavior.AllowGet);
}
View2 :
#using Enterprise_Dashboard.Models
#model ProfitRatingInfoModel
<script>
//Control not entering this section
$(document).ready(function () {
init_bind_rating_profit_table();
});
function init_bind_rating_profit_table()
{
debugger;
var RatingProfitData = #Model.ProfitRatingData;
alert(RatingProfitData[0].BU);
}
</script>
Is there any better way to redirect to different view from Ajax call with parameters.
from my View1, if i directly make Ajax call to View2, i cannot pass complex object as parameter, since its too big string.
Is there any way i can set RatingProfitDataMdl into Session or ViewBag or ViewData or anything else and i can access it in View2?
OR
Is there any way i can eliminate Ajax call on button click so button click on View1 will automatically call GetRatingProfitData and it internally redirects to RatingProfitReport with modal object parameter?
OR
Completely different approach available to handle this scenario?
What am trying to do is to post on form submit to a action and catch response and that works fine.Problem is when RedirectToAction gets called, it just stays on that same view(it doesn't redirect),or in case model is not valid, it doesn't show model validation. So i guess the problem is with url, but how can I correct it?
jQuery
$("form").on("submit", function (e) {
e.preventDefault();
var form = $(this);
var formURL = form.attr("action");
$.ajax({
type: "POST",
url: formURL,
data: $(this).serialize(),
success: function (response) {
if (response !== null && response.success == false) {
alert(response.responseText);
}
}
});
});
c# asp mvc
public ActionResult Add(SomeModel model) {
if (ModelState.IsValid) {
if (true) {
return Json(new { success = false, responseText = "Some error" }, JsonRequestBehavior.AllowGet);
}
return RedirectToAction("Details", new { id = id });
}
//gets called but it doesn't show validation.
return View(model);
}
public ActionResult Details(int id) {
//gets called but it doesn't show the view.
return view(model);
}
Because you're posting your form with an Ajax POST and your in your success function you have alert(response.responseText), you are NOT going to receive a View.
What you need to do is in success function, take the response from Details action and place it inside an HTML element on the page. Like below:
success: function (response) {
$("#div").html(response);
}
On another note, since you're not using a standard FORM and your posting with JavaScript, you wont get built in validation the models provide.
I'll preface this with I'm still new to JavaScript. So problem is in a larger application, our controller is passing in a list of information to the view where certain JavaScript functions rely on certain ViewModel properties. I've written a simple application to hopefully illustrate what I'm getting at.
Below is a sample controller that's passing in List to the Index page:
public ActionResult Index() {
List<int> activeIds = new List<int>();
SqlConnection sqlConn = new SqlConnection(connection_String);
sqlConn.Open();
string sqlStr = "SELECT * FROM dbo.[JS-Test] WHERE Active = 1";
SqlCommand sqlCmd = new SqlCommand(sqlStr, sqlConn);
SqlDataReader sqlDR = sqlCmd.ExecuteReader();
if(sqlDR.HasRows) {
while (sqlDR.Read()) {
activeIds.Add((int)sqlDR["ID"]);
}
}
sqlDR.Close();
sqlCmd.Dispose();
sqlConn.Close();
return View(activeIds);
}
This returns the current "active" items in the database. The (rough) view is as follows...
#model List<int>
#{
ViewBag.Title = "Index";
}
<p>Current Recognized Count: #Model.Count() </p>
Print
<script>
$(document).ready(function () {
$('#printBtn').click(function () {
var numberOfActiveIds = #Model.Count();
$.ajax({
type: "POST",
url: "/Home/PostResults",
data: { ids: numberOfActiveIds},
success: function (results) {
if(results == "Success") {
window.location.href = '/Home/Results';
}
}
});
});
});
</script>
The issue is getting the current number of active items from the database when the button is clicked. Let's say that the user remains idle on the page after it loads for a few minutes. When their page originally loaded, the model returned 5 items listed as active... but while they've been waiting 3 additional items were switched to active in the database for a total of 8. However, when the user finally clicks the button it'll submit 5 items instead of the current 8.
I'm unable to run the query to get the current number of active items in the "/Home/PostResults" ActionResult due to the nature of how the larger application is set up. Is there a way I could refresh the page (getting the updated model) before the rest of the function carries out using values of the refreshed model?
If you have any additional questions, please let me know and I will gladly comply. I've looked at other questions and answers on SO but I haven't found one that quite works for my situation. Thanks!
Edit #1
So, I've added this function to the Home controller which just returns the list count as Json.
public ActionResult GetIds(){
List<int> activeIds = new List<int>();
SqlConnection sqlConn = new SqlConnection(connection_String);
sqlConn.Open();
string sqlStr = "SELECT * FROM dbo.[JS-Test] WHERE Active = 1";
SqlCommand sqlCmd = new SqlCommand(sqlStr, sqlConn);
SqlDataReader sqlDR = sqlCmd.ExecuteReader();
if (sqlDR.HasRows) {
while (sqlDR.Read()) {
activeIds.Add((int)sqlDR["ID"]);
}
}
sqlDR.Close();
sqlCmd.Dispose();
sqlConn.Close();
return Json(activeIds.Count());
}
The view script now looks like this...
<script>
$(document).ready(function () {
$('#printBtn').click(function () {
var numberOfActiveIds = #Model.Count();
$.ajax({
type: "GET",
url: "/Home/GetIds",
success: function(response) {
numberOfActiveIds = response;
$.ajax({
type: "POST",
url: "/Home/PostResults",
data: { ids: numberOfActiveIds},
success: function (results) {
if(results == "Success") {
window.location.href = '/Home/Results';
}
}
});
}
});
});
});
</script>
I'm currently getting the following error...
Failed to load resource: the server responded with a status of 500 (Internal Server Error)
Edit #2
I had to set the JsonRequestBehavior to AllowGet for it to work properly. Thanks again, everyone!
gforce301 mentioned to GET the current actives via an ajax call to an additional, separate method making the query to the database and THEN ajax post the returned "actives". Is that possible?
Yes this is possible. That's why I mentioned it. Irregardless of other peoples opinions on how they think you should do this, I understand that you may be limited on why you can't do it their way even if they don't.
The code below is a restructuring of your code. It chains 2 ajax calls together, with the second one depending on the success of the first. Notice the comment block in the success handler of the first ajax call. Since I don't know what the response will be, I can't fill in the part on how to use it. This accomplishes your goal of having the user only make a single button click.
<script>
$(document).ready(function () {
$('#printBtn').click(function () {
var numberOfActiveIds = #Model.Count();
$.ajax({
type: 'GET',
url: '/path/to/get/activeIds',
success: function(response) {
/*
Since I don't know the structure of response
I have to just explain.
use response to populate numberOfActiveIds
now we just make our post ajax request.
*/
$.ajax({
type: "POST",
url: "/Home/PostResults",
data: { ids: numberOfActiveIds},
success: function (results) {
if(results == "Success") {
window.location.href = '/Home/Results';
}
}
});
}
});
});
});
</script>
I can give you an idea, i hope it can help,
run another ajax 1st on btnclick to get the data(or datat count) again, if the record count is greater then current then update the view and don't PostResults and if its same then just PostResults
on ajax success you can reload the data or view
and on failure(when no new record) just do PostResults
I am trying to display some data from my database that is dependent on some input from the user. I am using an ajax request to get the data, send it back to a function in my controller, and then export it back to my view. I would like to collect this data and display it without going to another view (I just hide the previous form and unhide the new form).
Here is the relevant code:
Javascript:
$('#submit_one').on('click', function(event) {
event.preventDefault();
if(! $(this).hasClass('faded')) {
var fbid = $("input[name='like']:checked").val();
//variable to be collected is fbid
request = $.ajax({
url: "http://crowdtest.dev:8888/fans/pick_favorite",
type: "post", success:function(data){},
data: {'fbid': fbid} ,beforeSend: function(data){
console.log(data);
}
});
to_welcome_two();
}
});
function to_welcome_two()
{
$('#welcome_one').addClass('hidden');
$('#welcome_two').removeClass('hidden');
}
Controller functions:
public function pick_favorite() {
$fbid=Input::get('fbid');
return Artist::specific_artist($fbid);
}
public function getWelcome() {
return View::make('fans.welcome')
->with('artists', Artist::artists_all())
->with('favorite_artist', Artist::favorite_artist())
->with('pick', FansController::pick_favorite());
}
Model function:
public static function specific_artist($fbid) {
$specific_artist = DB::table('artists')
->where('artists.fbid', '=', $fbid)
->get();
return $specific_artist;
}
The view is on the "welcome" page. My question is how do I display the model data in my view and make sure it is printing out the correct data from the fbid input?
I tried something like this:
#foreach($pick as $p)
<span class="artist_text">{{$p->stage_name}}</span>
<br>
<span class="artist_city">{{$p->city}}</span>
#endforeach
but this is not printing out anything. Any ideas?
i see lots of issues here.
Server side:
public function pick_favorite().... what does it do? it just returns some data.
in public function getWelcome() { , you wrote, FansController::pick_favorite(). supposing both are the same method, you are accessing a static method whilst the method is non static. you are getting an error for this but you are not seeing it because you didn't define fail().
and i don't see what the point of declaring a method which does nothing else then a model call which you can do directly.
e.g let's say i have a fooModel
public function index(){}
in controller, i can just write,
public function bar()
{
$model = new fooModel;
return View::make(array('param1'=>$model->index()));
}
or if i declare index() method in fooModel as static, then i can write,
public function bar()
{
return View::make(array('param1'=>fooModel::index()));
}
Client side:
now in your javascript,
$('#submit_one').on('click', function(event) {
event.preventDefault();
if(! $(this).hasClass('faded')) {
var fbid = $("input[name='like']:checked").val();
//variable to be collected is fbid
request = $.ajax({
url: "http://crowdtest.dev:8888/fans/pick_favorite",
type: "post", success:function(data){},
data: {'fbid': fbid} ,beforeSend: function(data){
console.log(data);
}
});
to_welcome_two();
}
});
function to_welcome_two()
{
$('#welcome_one').addClass('hidden');
$('#welcome_two').removeClass('hidden');
}
why it should print any data? you didn't asked the script to print anything. where is your .done or .success param in your code?
If you look at your console, you'l get lots of php errors, i am almost sure of.
an advice, you need to lear some basics. e.g. jquery ajax call.
a basic ajax call can be
var request = $.ajax({
url: "script.php",
type: "POST",
data: { id : menuId },
dataType: "html"
});
request.done(function( msg ) {
$( "#log" ).html( msg );
});
request.fail(function( jqXHR, textStatus ) {
alert( "Request failed: " + textStatus );
});
implement it in your code and then see what errors it throws.
Conclusion:
1st one will be (supposing rest of your codes are ok) the static error. if you want to call it as static, declare it as static. but a static function in controller? i don't see any purpose of it.
and then start the debug. your problem is both client and server side. deal one by one.
