How to change form background color on focus loss when text is entered?

阅读更多关于 How to change form background color on focus loss when text is entered?

问题 First I would like to point out that all of this is client side, not web based whatsoever. I need to have the form boxes change to green after focus loss when text has been input. The form boxes start out white, turn purple on focus, and i need them to turn green on a loss of focus when text is input. <!DOCTYPE html> <html> <head> <title>Login - Powered By Skyward</title> <link rel="icon" href="skyicon.gif"> <meta name="viewport" content="height=device-height, initial-scale=1.0"> <script type

Includes without local server?

阅读更多关于 Includes without local server?

问题 I'm making a website, and I like testing everything offline instead of having to upload files with every change I make. The problem is I can't use includes, so when I do upload, I'm going to have to change a lot of the file structure. I'm not looking to install a local server like WAMP when I just want to use includes. Is there any way? 回答1: Not really. You could process includes statically (e.g., write yourself a Makefile to create the actual HTML files you view locally). There are plenty of

What JavaScript library to use for client-side form checking?

阅读更多关于 What JavaScript library to use for client-side form checking?

问题 Over the years, I've dabbled in plain JavaScript a little, but have not yet used any JavaScript/AJAX libraries. For some new stuff I'm working on, I would like to use a js library to do client-side form validation, and want to know which would be best for that. By best, my criteria would be: quick and easy to learn, small footprint, compatible with all popular browsers. Edit: Thanks for the ASP suggestions, but they're not relevant to me.

The shapes are created as divs of class="shape" and the attributes are stored to each shape div using the data method. I'd like to be able to save the position and attributes of the shapes, in a JSON file, with a user defined name. Currently, I am using ajax and php to generate the JSON file and save it on the server. Any ideas or thoughts on how it should be done? Bonus points for libraries

问题 It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 6 years ago . Like we know that javascript is insecure as it is a client side script. Does JQuery is also insecure? If yes, than why we are seeing blogs on "JQuery replaces AJAX" and if not,than how it is different from

Moving from Page A to Page B in Asp.Net. What is the “Best” way?

阅读更多关于 Moving from Page A to Page B in Asp.Net. What is the “Best” way?

问题 I have a user on what we will call PageA.aspx. This user needs to get to PageB.aspx. The obvious way is have a hyperlink that simply sends them to PageB.aspx. That got me thinking about the other ways to get between pages. One could use javascript to do a client side jump. There is also the seemingly bulky server side redirection. What I would like to know is what, if any, are the performance hits between these different methods. I am going to assume the server side is a bit more heavy weight
