I copied an example from the dojo site using Borderlayout. However, when I load in the browser , the entire data is shown for all the section . Then after a few second the content is refersh and the data is displayed correctly.
here is code that i copied . Thanks for your help
<head>
<link rel="stylesheet" type="text/css" href="http://ajax.googleapis.com/ajax/libs/dojo/1.3/dijit/themes/tundra/tundra.css">
<style type="text/css">
body, html { font-family:helvetica,arial,sans-serif; font-size:90%; }
</style>
<style type="text/css">

{ width: 100%; height: 100%; }
</style>
</head>
<body class="tundra ">

style="width: 100px;">
Hi
</div>
<div dojoType="dijit.layout.ContentPane" splitter="true" region="center">
Hi, I'm center
</div>
</div>
</body>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/dojo/1.3/dojo/dojo.xd.js"
djConfig="parseOnLoad: true">
</script>
<script type="text/javascript">
dojo.require("dijit.layout.ContentPane");
dojo.require("dijit.layout.BorderContainer");
</script>
<!-- NOTE: the following script tag is not intended for usage in real
world!! it is part of the CodeGlass and you should just remove it when
you use the code -->
<script type="text/javascript">
dojo.addOnLoad(function() {
if (window.pub) {
window.pub();
}
});
</script>
This looks a bit upside down : you should put your javascripts in the head section and load the dojo libraries in first place. That's not your problem though.
What happens is that when the page loads, dojo loads all the modules that you "dojo.require", then parses all your tags containing the attribute "dojoType" and processes them for rendering, and this takes time.
So the flickering that you're seeing is the difference between the page before and after the widgets are parsed.
You should add a preloader div and hide it once the page is parsed (see this example).
This is what it would look like for your example :
<html>
<head>
<title>Preloader example</title>

obj[type+fn] = function(){obj['e'+type+fn]( window.event );}

disable parseOnLoad and manually add event to parse widgets for ie.

I am self-studying Vue.js. I am using v-bind to add the highlight class to the span element, which is supposed to add newBorder style to the element, but the style doesn't get applied.

Appreciate it if you can point out my mistake.
Thanks
Just change the class binding the array syntax instead of object :
<span v-bind:class="[loadClass,highlight]">

Currently I'm making vuejs SPA, and the build size is pretty big, so I want to place some loading indicator instead of blank page while vue is downloading its assets.
I've found out that in this case, the solution is v-cloak, but what I dont understand is, in every example the v-cloak is putted inside index.html, whereas in my project src there are no index.html, there is only main.js and vue.app.
there are index.html, but is located inside public folder(which i think its a build file?).
nevertheless, I've tried to put v-cloak directive inside Vue.app, and its still showing blank page while vue downloading its assets. please point me in the right direction.
thanks for all the help.
here's my App.vue:
<template>
<div id="app">
<div v-cloak>
<div class="v-cloak--inline"> <!-- Parts that will be visible before compiled your HTML -->
<i class="fa fa-spinner fa-pulse fa-3x fa-fw"></i>
<span class="sr-only">Loading...</span>
</div>
<div class="v-cloak--hidden"> <!-- Parts that will be visible After compiled your HTML -->
<!-- Rest of the contents -->
<router-view />
</div>
</div>
</div>
</template>
<script>
export default {
name: 'App'
}
</script>
<style>
[v-cloak] .v-cloak--block {
display: block;
}
[v-cloak] .v-cloak--inline {
display: inline;
}
[v-cloak] .v-cloak--inlineBlock {
display: inline-block;
}
[v-cloak] .v-cloak--hidden {
display: none;
}
[v-cloak] .v-cloak--invisible {
visibility: hidden;
}
.v-cloak--block,
.v-cloak--inline,
.v-cloak--inlineBlock {
display: none;
}
</style>
and when I put some loading indicator in public/index.html, it work, but how do I remove it after vue finished loading?
heres my public/index.html
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no">

Loading
<div id="app"></div>
<!-- built files will be auto injected -->
</body>
</html>
v-cloak is supposed to be used on the application's mounting point (the el specified in new Vue()), not within a component. Vue does not process v-cloak anywhere else but the mounting point, so it has no effect in App.vue.
To use v-cloak:
In public/index.html, add the v-cloak attribute to div#app, and a <style> block to hide it:
<div id="app" v-cloak></div>
<style>
[v-cloak] {
display: none;
}
</style>
Adjacent to div#app, add a loading icon, and style it so that it's hidden when the v-cloak attribute is removed (i.e., :not([v-cloak])):
<div class="loading">
<i class="fa fa-spinner fa-pulse fa-3x fa-fw"></i>
</div>
<style>
.loading {
display: grid;
place-content: center;
}
#app:not([v-cloak]) ~ .loading {
display: none;
}
</style>

DropDown
I'm using Bootstrap-vue. I need to make the b-dropdown-item-button wrap the text it's showing. How could I do that?
<template>
<b-dropdown menu-class="py-1" text="··· Actions">
<b-dropdown-item-button>Delete</b-dropdown-item-button>
</b-dropdown>
</template>
The dropdown has a min-width andwhite-space: nowrap` set by default, so you need to apply some css to override this.
window.onload = () => {
new Vue({
el: '#app'
})
}
<link type="text/css" rel="stylesheet" href="//unpkg.com/bootstrap/dist/css/bootstrap.min.css" />
<link type="text/css" rel="stylesheet" href="//unpkg.com/bootstrap-vue#latest/dist/bootstrap-vue.min.css" />
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.6.10/vue.js"></script>
<script src="https://unpkg.com/bootstrap-vue#2.0.4/dist/bootstrap-vue.min.js"></script>
<style>
/* Adding it here since it wasn't working in the snippet CSS */
body { padding: 1rem; }
/* Removes the min-width on the dropdown-menu and sets the width to 100% of the parent */
.wrap-dropdown {
width: 100%;
min-width: 0;
}
/* applies white-space: normal to all tags inside the dropdown-menu */
.wrap-dropdown * {
white-space: normal;
}
</style>
<div id="app">
<b-dd menu-class="py-1 wrap-dropdown" text="··· Actions">
<b-dd-item-btn>Delete</b-dd-item-btn>
<b-dd-item-btn>
This text is really long
</b-dd-item-btn>
</b-dd>
</div>
i am new to dojo and i am trying to make a button with an image, but the image does not show, besides, when one clicks the button, it correctly shows the "hi" alert.
the "zoom_in.png" image is right in the same directory with the html. And firebug shows no errors or warnings.
Update. thanks to ed, i managed to get it working via the declarative approach
<!DOCTYPE html>
<html >
<head>
<link rel="stylesheet" href="http://ajax.googleapis.com/ajax/libs/dojo/1.10.3/dijit/themes/claro/claro.css">
<script>dojoConfig = {parseOnLoad: true}</script>
<script src="//ajax.googleapis.com/ajax/libs/dojo/1.10.3/dojo/dojo.js"></script>
<script>require(["dojo/parser", "dijit/form/Button"]);</script>
<style>
.zoom_in_icon {
background-image: url('zoom_in.png');
height: 25px;
width: 25px;
text-align: center;
background-repeat: no-repeat;
}
</style>
</head>
<body class="claro">
<button data-dojo-type="dijit/form/Button" data-dojo-props="iconClass:'zoom_in_icon'" type="button">
<script type="dojo/on" data-dojo-event="click" data-dojo-args="evt">
require(["dojo/dom"], function(dom){
alert( "Thank you! ");
});
</script>
</button>
<div id="result2"></div>
</body>
</html>
However, programatically, the problem persists
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>Button</title>
<script src="//ajax.googleapis.com/ajax/libs/dojo/1.10.3/dojo/dojo.js" data-dojo-config="async: true"></script>
<style>
.zoom_in_icon {
background-image: url('zoom_in.png');
height: 250px;
width: 250px;
text-align: center;
background-repeat: no-repeat;
}
</style>
<script>
require([
"dijit/form/Button",
"dojo/domReady!"
],
function(Button) {
new Button({
title: 'Zoom in', iconClass:'zoom_in_icon',
onClick: function() { alert("hi"); }}, "zoom_in").startup();
});
</script>
</head>
<body>
<button id="zoom_in" type="button"></button>
</body>
</html>
thanks
If you want to create the button programatically you need to call startup() on the new Button, and you don't need the data-dojo-type="dijit/form/Button" or the parse in the html, if you want to create it declaratively you don't need the new button, but you need to set the icon in the html.
See the Programatic example here:
http://dojotoolkit.org/reference-guide/1.10/dijit/form/Button.html
Hi I have a simple one as shown below that displays bordercontainer and contentpane.
I do not understand why the bordercontainer's id is registered twice since I only have one
id defined for bordercontainer.
The error stated: Error: Tried to register widget with id==main_bContainer but that id is already registered
Please advise where I got it wrong.

Becuase you have parse() its 2 times.
Here dojoConfig = { parseOnLoad: true };
and here parser.parse();
Just parse only one the problem will solve.
