Chrome extension delay condition

Question

I have created a chrome extension which does something after its button is clicked. However I dont want it be abused so I need the its code to be executed after some time.

Answer 1

I had to make a compromise so just after the getSelected I added the following line:

chrome.browserAction.disable(tab.Id);

It disables the action button thus it cant be clicked while the script sends the data to the server, as with this extension I grab the tab url in order to store it in my database. After the ajax response and adding the following

if(xhr.readyState==4)
{
message.innerHTML=xhr.responseText;
chrome.browserAction.enable(tab.Id); /////<---THAT LINE
}

the button gets ready again to be clicked.

I couldnt find the way to add a specific delay in seconds, this way seems stupid but its working, as the response's delay from my server is enough for switching the 2 states of the action button.

With this, however another problem came up, which Ill write in different question.
