Javascript确认删除 - 如果没有提交表单？ 笨

Question

Is there a piece of Javascript that would stop a form submit button from carrying out a function

I am using the CodeIgniter framework which uses MVC pattern.

So when you click the button it calls a controller function which then calls a model function etc.

I tried using various things in Javascript including go back, history go back. Is there anything that will stop any event happening?

Here is my code:

function confirmation() {
    var answer = confirm("Delete Record?")
    if (answer)
    {

    }
    else
    {       //reloads current page - however it still continues to function
        window.redirect("http://localhost/midas/index.php/control_panel/user_records");
    }
}

It still continues to do the function if I say "Cancel". Is there any way to stop the browser?

This is my php code:

//js = is a variable which stores the javascript code
echo form_submit('view','View', $js);

This creates html output like so:

<input type="submit" onclick="confirmation()" value="View" name="view">

On the button which is causing the POST.. then put a function call on the OnClick event for that button. Have that function return true to continue with the POST or return false to cancel the action.
