问题 I am using itext 5.3 in java to generate PDF. I was using HTMLWorker.parseToList(Reader, StyleSheet) to convert part to String which contains HTML tags like Bold, Italic, href etc to PDF. I don't want to generate complete HTML to PDF instead a part of text in PDF will be HTML. For example, strings like "This is test bold text" to convert part of text to be bold. The performance is good with HTMLWorker . Since its deprecated now, I started using XMLWorkerHelper.parseXHtml(ElementHandler,

The jQueryUI ajax tabs example doesn't work

问题 I'm playing with jQueryUI, with the development-bundle, but having issues. So instead I'm trying another approach. Check out the example here: http://jqueryui.com/demos/tabs/ajax.html Click "Tab 2" and "Tab 3". Everything works fine. Now, I viewed and copied the html source code into a local file, and replaced all relative paths to absolute paths as such: <!DOCTYPE html> <html lang="en"> <head> <meta charset="utf-8"> <title>jQuery UI Tabs - Content via Ajax</title> <link rel="stylesheet" href

Helper for tag html a

由 佐手、 提交于 2020-01-04 04:57:29
问题 is there any helper in asp.net MVC3 <a href="www.google.com">Go to Google </a> ? Not for an action but to a static link 回答1: I don't believe there is, but I'm not sure why you would want one. You'd actually end up with more code: <a href="http://www.google.com/">Go to Google</a> <%: Html.Link("http://www.google.com/", "Go to Google") %> @Html.Link("http://www.google.com/", "Go to Google") Update: If you want to create a Link() helper like that above, you would use an extension method: public

问题 I have Apache set up on my own Centos server with several virtual web servers, and I wish to enable PHP short tags for only one of those web servers which is located at /var/www/ostickets/html . I can successfully enable short tags by adding short_open_tag=On to php.ini, however, I don't wish to globally do so, but only the one site. I've tried the following, however, nothing is displayed. I've looked at various logs, and cannot detect any errors. Is it possible that I inadvertently disabled
