I am making a hybrid application using webView in swiftUI. By the way, when I submit the form in javascript, There is a problem that the ID value is not transmitted to the controller.

        document.form.Id.value = id;
        document.form.action = "<c:url value='/SampleView.do'/>";
        document.form.target="target";
        document.form.submit();

It works fine in Chromenium. It is said that swiftUI's webView uses a different method. Please guide me.
