client-side

问题 Is it possible to write a string to a file (create the file if it doesn't exist) without any external Javascript libraries , purely with Javascript code ? I'm trying to implement a client side code that whenever it reaches a page (.ASPX) it writes few strings into a file (let's say output.txt ) and that's it . From everything I see over the internet , JavaScript is not allowed to write anything to the hard drive . Is that so ? no workarounds ? 回答1: As said in the comments, what you sound to

问题 This link explains how to handle it on the server side via the ASPxGridView.AfterPerformCallback event: http://www.devexpress.com/Support/Center/p/Q274366.aspx How can I handle it on the client side? I am working on a custom server control and I have this client side function on my control: applyFilterToGridView: function () { this.theGridView.ApplyFilter(this.filterCondition); this.filterAppliedEvent(); } Because ApplyFilter does a callback, this.filterAppliedEvent() is not called at the

问题 My question is regarding this quote from the manual about dates in JavaScript: Note: parsing of date strings with the Date constructor (and Date.parse, they are equivalent) is strongly discouraged due to browser differences and inconsistencies. new Date('2016-04-14') output for a user was Wed Apr 13 2016 17:00:00 GMT-0700 (US Mountain Standard Time) upon which he had to use .toUTCString() . How to handle this if the users are in many different time zones? 回答1: new Date().getTime(); returns an

问题 I've got a form that I'm submitting based on a div click. I also have it launching a waiting indicator when clicked. I'm trying to find out if there is a way to detect if client side validation failed or not so that I can remove the waiting indicator/never show it after a submit attempt...or can I call the the client side validation manually before I attempt the submit? 回答1: you can try $('div').click(function() { if ($('form').valid()) { //form is valid else{ //invalid form } } }); 来源： https

问题 I have a need to monitor the state of the Shift key, whether it is up or down. Its purpose is to notify the user that while the shift key is held down, the drag and drop operation they are about to perform is going to COPY the node(s), and not move them. I have it working perfectly with the code below, however, if I hold the Shift key and perform the drag and drop, the hook no longer exists; the screen no longer responds to the key press and remains in the "pressed" state. I'm guessing there

问题 I have a static HTML web page and I want to set its status code to 404 "Not found". But, I want to do this using javascript or jQuery, not any server side language. How can I do this on the client? With javascript or maybe a <meta> tag? 回答1: It is impossible to set the HTTP Response code using client side programming. 回答2: I think the sense behind this exercise is the following: You want to load a page that displays a custom error message to your users. At the same time you want to tell your

问题 I have run into an issue where a lot of our support calls are about our images not loading because the user is blocking amazon s3 or a similar 3rd party service. I use 3rd party services for hosting images, video, and some javascript. Is there a way to detect through javascript if a client is blocking a domain so that we display a message instead of having the user contact support? $.ajax 'http://aws.amazon.com/s3/', type: 'GET', dataType: 'html' complete: (e, xhr, settings) -> if e.status ==
