Thats why I decided to use lazy load: http://www.appelsiini.net/projects/lazyload My page is this one: http://www.mysecretathens.gr/kulte_test/osterman.html I followed all the instructions that are required but dont understand why the first images that I wanted to test the lazy load function dont display In my head section is this: <script src="jquery.js" type="text/javascript"></script> <script src="lazyload.js" type="text/javascript"></script> the images: <img

问题 I am trying to set background for the image view. But not got luck to set background using universal image loader. I am using following code. DisplayImageOptions options = new DisplayImageOptions.Builder() .showStubImage(R.drawable.mo_no_image) .showImageForEmptyUri(R.drawable.mo_no_image) .cacheInMemory().cacheOnDisc() .displayer(new RoundedBitmapDisplayer(0)) .imageScaleType(ImageScaleType.EXACTLY).build(); ImageLoader.getInstance().displayImage("url_to_load_image", imgView, options); By

问题 I've developed an application that populates a treeview from hierachical data in a database. I've designed it to use lazy-loading so it only gets the child nodes when a node is expanded. My problem is that obviously I don't know if a node has children unless I make a call to the database and look. Currently I have implemented a dummy child node, so that the [+] icon appears for all nodes, I then remove this dummy node and get the real child nodes in the BeforeExpand event. This means I get a

问题 The following code appears to force line-seq to read 4 lines from file . Is this some kind of buffering mechanism? Do I need to use lazy-cat here? If so, how can I apply a macro to a sequence as if it were variadic arguments? (defn char-seq [rdr] (let [coll (line-seq rdr)] (apply concat (map (fn [x] (println \,) x) coll)))) (def tmp (char-seq (clojure.contrib.io/reader file))) ;, ;, ;, ;, #'user/tmp 回答1: Part of what you're seeing is due to apply , since it will need to realize as many args

问题 I am trying to implement a lazy load for a large set of data with primeng <p-datatable> . I have done everything documented on the official site, however I could not make it work. The onLazyLoad callback runs only once at the time of loading the table. It doesn't trigger on each scroll as expected. <div style="max-height:300px; border:1px solid black;overflow-y:auto"> <p-dataTable #pocListref [value]="data" rowHover="true" [(selection)] = "selectedData" scrollable="true" scrollHeight="200px"

问题 Hope you'll be able to help me stop hitting my head against a wall. Here's my problem, after plenty days of research on many forums, I didn't found any compatible answer with the problem i'm encountering. I have the org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role: com.supinfo.suppicture.entity.User.pictures, no session or session was closed that seems to be a known Exception, but still drives me crazy... I've tried to force Eager loading instead of

问题 Does anyone know howto get lazyloading on firebase hosting working? It all works but when I view the source code of my site, I only see the router-outlet and not the text and so on. I've added the code below to my index.js inside the functions folder: extraProviders: [ provideModuleMap(LAZY_MODULE_MAP) ] My app.server.module file looks like this: import { NgModule } from '@angular/core'; import { ServerModule } from '@angular/platform-server'; import { AppModule } from './app.module'; import

问题 The vuejs common components which I created as a web-component and uploaded to npm doesn't work when I installed it to a different file. I think it's because of lazy-loading. I tried searching some fixes but I can't find that fixed my problem. On chrome and firefox error images are provided I am using this code on importing the components inside web-components. components: { 'data-description-c': () => import(/* webpackChunkName: "data-description-c" */ './myPage/DataDescriptionC.vue'), 'data

问题 I have a simple Ionic3 app with a couple of lazy loaded pages (using IonicPage ) and a login page. I want to block all access to any page unless the user is first logged in. Knowing that this is to build a website version and not a cordova version, what is the best way to prevent the user for simply typing in the url of the lazy loaded pages and access them without logging in? I'm guessing there must be some way to "tap" into the navigation and redirect to the login page from there but cannot

问题 Is there an iOS 5 arc compatible lazy Image loading library? I've not found one. My next thought is to make EGOlazyloading a compiled library and link it to my project. Would that work? Any pointers on going about? Thanks! 回答1: I wrote one. You can download it here: https://github.com/nicklockwood/AsyncImageView Alternatively, if you do want to use EGO, or some other library, select Edit>Refactor>Convert to ARC and in the dialog that comes up there's a little drop down to select which files
