阅读更多关于 How can I compare date/time values using the jQueryUI datepicker and HTML5 time input?

I want to validate that the "begin" date/time pair predates the "end" date/time pair on a page. I'm using the jQueryUI datepicker, and the HTML5 time input element/widget. This jQuery: var begD = $.datepicker.parseDate('mm/dd/yy', $('#BeginDate').val()); var endD = $.datepicker.parseDate('mm/dd/yy', $('#EndDate').val()); if (begD > endD) { alert('Begin date must be before End date'); $('#BeginDate').focus(); return false; } (see this script in context here: http://jsfiddle.net/clayshannon/QCrXG/9/ ) ...works for comparing the datepicker vals, but I need to incorporate the time elements too, so

How to manually rerun formatter chain in angularjs directive with ngModel?

阅读更多关于 How to manually rerun formatter chain in angularjs directive with ngModel?

Angular.js ngModel has the ability to declare a chain of parsers and formatters . Some more details can be found at the great answer to 'How to do two-way filtering in angular.js?' now the formatter chain only will be run if the ngModel will update. so if you have a second input-parameter that affects the viewValue (is used in one of the formatters) this will not trigger an update of the View. similar as far as i found ngModel only uses a simple $watch - so if your model is a collection/object it will not trigger if sub-elements are changed.

Have a file input form upload when a user clicks “open”

阅读更多关于 Have a file input form upload when a user clicks “open”

I am wondering if this flow is possible: Click a button that says "Upload". It is styled very differently from the usual . It does not show the "No file selected" text. The usual file browser pops open. The user chooses a file to upload. They click the "open" button in the file browser. Upon clicking "open", the file browser is closed (like normal) and the file immediately begins uploading (unlike normal where it requires a submit). I detect when the file is finished uploading, and direct to another page. Here is how I would try to implement it: Custom CSS on input button - this doesn't seem
