I have to refresh a div in a Lightning Component, the same as how we use rerender in a Visualforce Page. How can I do so?

While browsing any salesforce document from my chrome browser I'm getting this error, in incognito window or in other browser it's working fine. I have lready cleared my browser cache and cookies.

Any idea about the issue?

How can I make a modal dialog page from a custom button. Guys if you have any idea please get back to me
