In general, it's not possible to call a server-side controller method directly from client-side JavaScript without making a request to the server. However, there are a few different approaches you could take to achieve similar functionality without using AJAX.
- Using a form submission:
One way to call a server-side controller method from client-side JavaScript is by creating a hidden form on the page and submitting it with JavaScript. You can set the form action to the URL of the controller method, and then submit the form using JavaScript.
For example, suppose you have a controller method called `MyController.Method1` that you want to call. You could create a form like this:
<formid="myForm"method="post" action="/MyController/Method1">
<input type="hidden" name="parameter1" value="value1" />
<input type="hidden" name="parameter2" value="value2" />
</form>
Then, in your JavaScript code, you can submit the form using the `submit()` method:
document.getElementById('myForm').submit();
When the form is submitted, the controller method will be executed on the server.
- Using a link with a `target` attribute:
Another approach is to create a link on the page that points to the URL of the controller method, and set the `target` attribute to a hidden iframe on the page. This will cause the server response to be loaded into the iframe, without changing the main page.
For example, you could create a link like this:
<a id="myLink" href="/MyController/Method1" target="hiddenFrame">Call Method</a>
<iframe id="hiddenFrame" name="hiddenFrame" style="display:none;"></iframe>
Then, in your JavaScript code, you can simulate a click on the link using the `click()` method:
document.getElementById('myLink').click();
When the link is clicked, the controller method will be executed on the server and the response will be loaded into the hidden iframe.
Note that both of these approaches still involve making a request to the server, so they are not truly "without using AJAX." However, they may be useful in situations where you need to perform a server-side action without refreshing the entire page or using an explicit AJAX request.
