Taken from the underscore site: It’s the tie to go along with jQuery’s tux, and Backbone.js’s suspenders. Underscore is more suited to data manipulation and brings many Ruby methods to JavaScript. There is some crossover, but not enough to make them mutually exclusive.
It is just such simple as writing: $(‘input[type=file]’).val() Anyway, I suggest using name or ID attribute to select your input. And with event, it should look like this: $(‘input[type=file]’).change(function(e){ $in=$(this); $in.next().html($in.val()); });
The capitalization is wrong, and you have an extra argument. Do this instead: $(‘img#thumb’).removeAttr(‘id’); For future reference, there aren’t any jQuery methods that begin with a capital letter.

You can include all the stylesheets in the document and then activate/deactivate them as needed. In my reading of the spec, you should be able to activate an alternate stylesheet by changing its disabled property from true to false, but only Firefox seems to do this correctly. So I think you have a few options: … Read more

window.location.pathname will get you the directory, as well as the page name. You could then use .substring() to get the directory: var loc = window.location.pathname; var dir = loc.substring(0, loc.lastIndexOf(“https://stackoverflow.com/”)); Hope this helps!
$(document).prop(‘title’, ‘test’); This is simply a JQuery wrapper for: document.title=”test”; To add a > periodically you can do: function changeTitle() { var title = $(document).prop(‘title’); if (title.indexOf(‘>>>’) == -1) { setTimeout(changeTitle, 3000); $(document).prop(‘title’, ‘>’+title); } } changeTitle();
Just: $(‘#edit-submitted-first-name’).removeAttr(‘required’); If you’re interested in further reading take a look here.
var scrollBottom = $(window).scrollTop() + $(window).height();
