Is it possible to run jQuery from a MVC C# controller?
if (ModelState.IsValid){
//lots of C# asp.net code here
jqueryFunctionName();
}
It's important that there is a check somehow before the jQuery runs
Perhaps i can do it straight from jQuery itself, but i'm not sure how to check it?
The idea is Form -> Submit -> SOMETHING checks if valid -> if yes then wait graphic -> 2 seconds pauze -> redirect to "thanks.cshtml"
In your controller's action:
var vm = new YourViewModelTypeWithPropertyIsValid();
vm.IsValid = ModelState.IsValid;
return View(vm);
In your view:
@model YourViewModelTypeWithPropertyIsValid
<script type="text/javascript">
var isModelValid = @Model.IsValid ? 'true' : 'false';
$( document ).ready(function() {
// Any JS code here
// ...
if (isModelValid) {
setTimeout(
function () {
location.assign('/redirect_path_after_2s_delay');
},
2000);
);
}
});
<script>
I prefer typed views.
If you use untyped views, use the code below.
In your controller's action:
ViewData["IsModelValid"] = ModelState.IsValid ? "true" : "false";
return View();
In your view:
<script type="text/javascript">
var isModelValid = @ViewData["IsModelValid"];
$( document ).ready(function() {
// Any JS code here
// ...
if (isModelValid) {
// See the code above.
}
});
<script>
If the code runs in the view then you can try something like this. is a special asp tag. If the should indeed run in controller, than it is not possible to run JS code there.
if (ModelState.IsValid){
//lots of C# asp.net code here
<text>
<script>
jqueryFunctionName();
</script>
</text>
}
