问题 What I want is like stack overflow. User can HTML format their text input, and the page should be rendered exactly in the same way, I use the wmd.js to store the formatted input, Consider I have a context variable {{variable}} with string value "<p>something</p>" . When I render the template, {{variable}} outputs <p>something</p> and {{variable|safe}} also output <p>something</p> It shows the html tag as text in the page. How to render the HTML tag in the {{variable}} but not showing them as

问题 I'm using the code below to print the out the field of nodes to specific areas and it works great. But theres an instance where I just want to print the value you of field without the label. Seems as it should be pretty easy but I'm having a bit of trouble. I'd appreciate any help as i'm pretty new to drupal. Thanks <?php print drupal_render(field_view_field('node', $node, 'field_description')); ?> 回答1: field_view_value() takes a $display argument that you can use to hide the label: $display

问题 I'm looking for a way to load up a page and save the rendering as an image just as you would do with CutyCapt (QT + webkit EXE to do just that). At the moment and without JavaFX, I do it by calling an external process from java and rendering to file than loading that file into an ImageBuffer... Neither very optimized nor practical and even less cross platform... Using JavaFX2+ I tried playing with the WebView & WebEngine: public class WebComponentTrial extends Application { private Scene

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed last year . I'm working on an application that needs to quickly render simple 3D scenes on the server, and then return them as a JPEG via HTTP. Basically, I want to be able to simply include a dynamic 3D scene in an HTML page, by doing something like: <img src="http://www.myserver.com/renderimage?scene=1&x=123&y=123&z=123">

问题 I am trying to build an app in Shiny that (1) asks user for number of Assets in his/her portfolio. Depending on the numeric entry, (2) the user is presented with one numeric box to enter the % of portfolio owned AND the Ticker/name of the Asset. For instance, If the user enters 3 for number of assets in portfolio, he will be presented with something like this: Asset1 ----> Enter ticker______ Enter Wight______ Asset2 ----> Enter ticker______ Enter Wight______ Asset3 ----> Enter ticker______

问题 I have a class MyData.php like this: class myData { function render() { $view = new Zend_View(); $view->str = 'This is string.'; echo $view->render('myview.phtml'); } } and a myview.phtml file: <div id='someid'><?= $this->str ?></div> In another view I am doing something like this: <?php $obj = new myData (); $obj->render(); // it should be <div id='someid'>This is string.</div> ?> It is giving me following exception: Message: no view script directory set; unable to determine location for

问题 The initialize method is called but render method is not. I read about subclassing on the fabricjs website and looked at that demo. I really don't understand what is missing in my code. var CustomCircle = fabric.util.createClass(fabric.Object, { type: "customCircle", initialize: function (options) { this.callSuper('initialize', options); }, _render: function (ctx) { ctx.beginPath(); ctx.arc(100, 250, 50, 0, 2 * Math.PI, false); ctx.fillStyle = 'green'; ctx.fill(); ctx.lineWidth = 5; ctx

问题 Here's the code: render :file => @somedir + "/blah.xml" ...but the resulting MIME type is text/html when I check in FireBug. How do I specify a MIME type in this case? 回答1: Actually there are two ways to set the content-type (I think this is what you mean by mime-type). You should use the second option, if it works for your Rails version. class FileController < ApplicationController def index filename = 'some.xml' extname = File.extname(filename)[1..-1] mime_type = Mime::Type.lookup_by

问题 I know that modern browsers generally have two render mode: standard mode and quirk mode. The browser detects the heading DocType. The question is how to detect render mode of current page at runtime. Is there any Firebug tool to do that? 回答1: Before IE8: alert('Page was rendered in ' + ((document.compatMode == 'CSS1Compat') ? 'Standards' : 'Quirks') + ' Mode.'); For IE8: var vMode = document.documentMode; var rMode = 'IE5 Quirks Mode'; if(vMode == 8){ rMode = 'IE8 Standards Mode'; } else if

问题 I'm trying to figure out a way to display images from a mounted file system that is not under RAILS_ROOT (in RedHat or Ubuntu environments). I don't want to use a symbolic link because this app is actually deployed through Tomcat, and Tomcat tries to follow the symbolic link and delete all the images in the mount when I shut down Tomcat. Putting the images under public/images is also not an option due to the number and size of these files. I looked into send_file, but that will just display
