Short & Snazzy:
+ new Date()
A unary operator like plus triggers the valueOf method in the Date object and it returns the timestamp (without any alteration).
Details:
On almost all current browsers you can use Date.now() to get the UTC timestamp in milliseconds; a notable exception to this is IE8 and earlier (see compatibility table).
You can easily make a shim for this, though:
if (!Date.now) {
Date.now = function() { return new Date().getTime(); }
}
To get the timestamp in seconds, you can use:
Math.floor(Date.now() / 1000)
Or alternatively you could use:
Date.now() / 1000 | 0
Which should be slightly faster, but also less readable.
(also see this answer or this with further explaination to bitwise operators).
I would recommend using Date.now() (with compatibility shim). It's slightly better because it's shorter & doesn't create a new Date object. However, if you don't want a shim & maximum compatibility, you could use the "old" method to get the timestamp in milliseconds:
new Date().getTime()
Which you can then convert to seconds like this:
Math.round(new Date().getTime()/1000)
And you can also use the valueOf method which we showed above:
new Date().valueOf()
Timestamp in Milliseconds
var timeStampInMs = window.performance && window.performance.now && window.performance.timing && window.performance.timing.navigationStart ? window.performance.now() + window.performance.timing.navigationStart : Date.now();
console.log(timeStampInMs, Date.now());
The jQuery constructor accepts a 2nd parameter called context which can be used to override the context of the selection.
jQuery("img", this);
Which is the same as using .find() like this:
jQuery(this).find("img");
If the imgs you desire are only direct descendants of the clicked element, you can also use .children():
jQuery(this).children("img");

Having a "Next" button instead of "Go" is not possible with Android as of now.
Android will always display "Go" button for form input fields. "Go" is basically reflecting the same behavior as of an "Enter" button on a normal browser & keyboard. You can achieve through below code:
OR
If your input fields are more, then data-dependency will be best solution. If you want to prevent users from submitting the form, you can put required validations on the form using javascript, where you can specify data-dependency inside input field with required, which helps move cursor to a particular field which you specified in data-dependency.
It move focus to next fields in form until its your last field. Once last field reaches you can allow it to act as enter. So basically Go will keep moving focus to next fields until its your last field & then will submit the form.
