Auto-click function for  google sign button using javascript

(Function to initialize google sign process)

I have added google sign button on my website. On clicking on it i can make user to login in my application using google account.

Now i want to click on some other button and want to initialize google sign functionality .

To do so i need 2-3 lines of code / a function to start login process.

var myParams = {
    'clientid': 'your client-id',
    'cookiepolicy': 'single_host_origin',
    'callback': 'onSignInCallback',
    'scope': 'email'
};
gapi.auth.signIn(myParams);
