To fix the issue you can do The workaround is to set the UIWebView delegate to a class and watch for the -webView:shouldStartLoadWithRequest:navigationType: method. Just pass a URL to it by using window.location or and parse the URL to call the Objective-C method you want.

I hope this helps . Use the __doPostBack method exposed for JavaScript. If you pass in the ID of the button and event name, it essentially performs the same postback to the server as though the user clicked the button.
ASP.NET postback with JavaScript (this uses VB code-behind, but otherwise does what you need I think)

Any of those help You can't.
When you do a postback in Webforms you have lost the client. Say it did work - should the javascript run on the page that is about to close or magically appear on the upcoming page?

Call java method on button click

will help you If you have an ActionBean (which is a servlet deep down), you can bind an URL to it with @UrlBinding (as you already do). You just need to make a HTTP request to that URL using Ajax in the 'click' event handler of the button.
So you could have this markup:

code :

<stripes:form beanclass="com.example.action.TestMeActionBean">
    <input type="button" value="Test" onClick="testMe()"/>
</stripes:form>
<script>
function testMe () {
    $.ajax({
        type: 'post',
        url: 'action/testMeAction',
        ...
    });
}
</script>

@UrlBinding("/action/testMeAction")
public TestMeActionBean implements ActionBean {

    @DefaultHandler
    public void testMe() {
        //do something
    }
}
