here is my code
var parser = window.less.Parser();
try{
parser.parse(aztp_css_editor.getValue(), function(error, result){
if(!error){
alert(result.toCSS());
}else{
alert(error);
}
});
}catch(error){
alert(error);
}
I have a mixins less file here http://lessprefixer.com/ for shorthand css3 prefix, how I setup it into my parse less code?
I think you should better the less.render function, see also: http://lesscss.org/usage/#programmatic-usage.
But indeed you can use the #import directive as already made clear by #seven-phases-max.
Example:
<script src="//cdnjs.cloudflare.com/ajax/libs/less.js/2.1.0/less.min.js"></script>
<script>
less.render('#import "test.less"; p {color: #red; }', {'include-path': 'test/'})
.then(function(output) {
// output.css = string of css
// output.map = string of sourcemap
// output.imports = array of string filenames of the imports referenced
console.log(output.css);
},
function(error) {
});
</script>
The above compiles well (results in output.css) when test.less is available in the same path as the html which contains the code. You can also use a path in your import, '#import "path/test.less"; I did not found that setting include-path has any effect.

I found a codepen.io example (https://codepen.io/srees/pen/pgVLbm) I want to play around with in the context of a .vue app I'm working on, and I need some help transferring the <script> section over.
I copied the HTML chunk into a <template> and the CSS into a <style>. I've confirmed the .vue file works within the broader context (content loads when the <script> is commented out. I also placed <script src="http://ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js" /> immediately before my <script> to resolve the $ not defined error I was getting. Is there something I need to import into App.vue or into this particular .vue file? When I leave <script> uncommented, I simply get a blank page loaded.
<script src="http://ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js" />
<script>
var hidWidth;
var scrollBarWidths = 40;
...
you could define a method like this:
methods: {
renderStuff: function () {
var hidWidth;
var scrollBarWidths = 40;
var widthOfList = function(){
var itemsWidth = 0;
$('.list li').each(function(){
var itemWidth = $(this).outerWidth();
itemsWidth+=itemWidth;
});
return itemsWidth;
};
var widthOfHidden = function(){
return (($('.wrapper').outerWidth())-widthOfList()-getLeftPosi())-
scrollBarWidths;
};
var getLeftPosi = function(){
return $('.list').position().left;
};
var reAdjust = function(){
if (($('.wrapper').outerWidth()) < widthOfList()) {
$('.scroller-right').show();
}
else {
$('.scroller-right').hide();
}
if (getLeftPosi()<0) {
$('.scroller-left').show();
}
else {
$('.item').animate({left:"-="+getLeftPosi()+"px"},'slow');
$('.scroller-left').hide();
}
}
reAdjust();
$(window).on('resize',function(e){
reAdjust();
});
$('.scroller-right').click(function() {
$('.scroller-left').fadeIn('slow');
$('.scroller-right').fadeOut('slow');
$('.list').animate({left:"+="+widthOfHidden()+"px"},'slow',function(){
});
});
$('.scroller-left').click(function() {
$('.scroller-right').fadeIn('slow');
$('.scroller-left').fadeOut('slow');
$('.list').animate({left:"-="+getLeftPosi()+"px"},'slow',function(){
});
});
}
}
and run the method on mount like this:
mounted() {
this.renderStuff();
}
Side note, var is not ideal in this day and age. Recommend converting these to let.
I realized that I can make sure of Promise.resolve to convert an Angular JS $q.defer() logic. However, I got the following problem:
Original Angular JS:
service.validValues = function(id,name) {
var deferred = $q.defer();
$q.all([service.check_id(id), service.check_name(name)]).then(
function(student){
service.validStud(student[0], student[1]).then(function(valid) {
deferred.resolve(valid);
});
});
return deferred.promise;
};
my code:
validValues(id, name) {
let deferr = new Promise(deferred);
function deferred(resolve, reject) {
Observable.forkJoin([this.check_id(id), this.check_name(name)]).subscribe((student) => {
this.validStud(student[0], student[1]).then(function(valid) {
resolve(valid);
});
});
return deferr;
}
Is it wrong? Cause I never got the valid values. Although the code can be compiled but I always got "undefined" for 'deferr' when I do a console.log.
Thank you so much!
Is there a way to have a static variable in a dojo (1.8) module so that I can retain state?
Example, say I set some value in some/module
require([
'some/module'
], function (module) {
module.setSomeValue(3);
});
.. and then want to retrieve it later
define([
'some/module'
], function(module) {
return {
start: function() {
var x = module.getSomeValue();
}
};
});
A solution that works but seems like a hack,
acompany = window.acompany || {};
acompany.project = acompany.project || {
};
require([
], function() {
var debug = false;
acompany.project.module = {
/* static variables and functions here */
};
});
define([
], function () {
return acompany.project.module;
});
Actually there is always only single instance of AMD module, because (source):
define has two additional important characteristics that may not be immediately obvious:
Module creation is lazy and asynchronous, and does not occur immediately when define is called. This means that factory is not executed, and any dependencies of the module will not be resolved, until some running code actually requires the module.
Once a module value has been entered into the module namespace, it is not recomputed each time it is demanded. On a practical level, this means that factory is only invoked once, and the returned value is cached and shared among all code that uses a given module. (Note: the dojo loader includes the nonstandard function require.undef, which undefines a module value.)
In addition you do not have to provide just factory function, you can provide an object literal as well:
define("some/module", {
someValue: "some",
otherValue: "other"
});
Then somewhere else in your code:
require(["some/module"], function(module) {
console.log("module.someValue", module.someValue); // some
module.someValue = "some changed";
});
require(["some/module"], function(module) {
console.log("module.someValue", module.someValue); // some changed
});
More robust solution includes an instance of dojo/Stateful, so you can watch for changes and define custom setters and getters:
define("some/stateful-module", ["dojo/Stateful"], function(Stateful){
var stateful = new Stateful({
someValue: "some",
otherValue: "other"
});
return stateful;
});
Then somewhere else in your code:
require(["some/stateful-module"], function(module) {
console.log("stateful-module.someValue:", module.get("someValue"));
module.watch(function(name, oldValue, newValue) {
console.log("stateful-module: property"
, name
, "changed from"
, "'" + oldValue + "'"
, "to"
, "'" + newValue + "'"
);
});
});
require(["some/stateful-module"], function(module) {
module.set("someValue", "some changed");
});
See how it works at jsFiddle: http://jsfiddle.net/phusick/fHvZf/. It's in a single file there, but it will work the same way across the whole application unless you require.undef(mid) the module.
There are multiple files in Dojo like dojo/date/locale that define static variables and functions and not widgets/classes using dojo.declare.
Define the module
define([
'dojo/_base/lang/',
'some/module'
], function(lang, module) {
var m = lang.getObject('some.module', true);
m.x = 0;
m.doSomething = function(){
// doSomething
};
return m;
});
Use the module
require([
'some/module'
], function(someModule) {
var debug = false;
/* someModule - static variables and functions here */
if(someModule.x == 0){
}
});
I'm a beginner in dojo, and I'm trying to print the output to console using dojo code. But I don't what's the problem in the following code, and how can I print the output to the console?
<html>
<head>
<script type = "text/javascript" src = "dojo/dojo.js" data-dojo-config = "async: true, isDebug : true" >
</script>
</head>
<body>
<h1 id = "greeting">Hello</h1>
<script>
define(["dojo/dom"],function(dom) {
var Twitter = declare(null, {username:"defaultusername",
say :function(msg)
{
console.log("Hello "+msg);
}
});
var myInstance = new Twitter();
myInstance.say("Dojo");
});
</script>
</body>
</html>
Use require instead of define:
<script>
require(["dojo/dom", "dojo/_base/declare"], function(dom, declare) {
var Twitter = declare(null, {
username: "defaultusername",
say :function(msg) {
console.log("Hello "+msg);
}
});
var myInstance = new Twitter();
myInstance.say("Dojo");
});
</script>
Console works, but your code inside callback function in declare is not being executed until you require it.
You cannot define in inline script code, that is meant to be a class define, put in the topmost line of a class-file, meaning define maps the filename to the returned value of its function.
This means, if you have
dojo_toolkit /
dojo/
dijit/
dojox/
libs/
myWidgets/
foo.js
And foo.js reads
define(["dijit._Widget"], function(adijit) {
return declare("libs.myWidgets.foo", [adijit], function() {
say: function(msg) { console.log(msg); }
});
});
Then a new module is registered, called libs / myWidgets / foo. You should make sure that the returned declare's declaredClass inside each define matches the file hierachy.
That being said, reason why define does not work for you is the explaination above. It is inline and has no src to guess the declaredClass name from. Rewrite your code to define("aTwitterLogger", [":
define("aTwitterLogger", ["dojo/_base/declare", "dojo/dom"],function(declare, dom) {
var Twitter = declare(null, {
username:"defaultusername",
say :function(msg)
{
console.log("Hello "+msg);
}
});
var myInstance = new Twitter();
myInstance.say("Dojo");
});
In my ExtJS 4.0.7 app I have some 3rd party javascripts that I need to dynamically load to render certain panel contents (some fancy charting/visualization widgets).
I run in to the age-old problem that the script doesn't finish loading before I try to use it. I thought ExtJS might have an elegant solution for this (much like the class loader: Ext.Loader).
I've looked at both Ext.Loader and Ext.ComponentLoader, but neither seem to provide what I'm looking for. Do I have to just "roll my own" and setup a timer to wait for a marker variable to exist?
Here's an example of how it's done in ExtJS 4.1.x:
Ext.Loader.loadScript({
url: '...', // URL of script
scope: this, // scope of callbacks
onLoad: function() { // callback fn when script is loaded
// ...
},
onError: function() { // callback fn if load fails
// ...
}
});
I've looked at both Ext.Loader and Ext.ComponentLoader, but neither
seem to provide what I'm looking for
Really looks like it's true. The only thing that can help you here, I think, is Loader's injectScriptElement method (which, however, is private):
var onError = function() {
// run this code on error
};
var onLoad = function() {
// run this code when script is loaded
};
Ext.Loader.injectScriptElement('/path/to/file.js', onLoad, onError);
Seems like this method would do what you want (here is example). But the only problem is that , ... you know, the method is marked as private.
This is exactly what newest Ext.Loader.loadScript from Ext.4-1 can be used for.
See http://docs.sencha.com/ext-js/4-1/#!/api/Ext.Loader-method-loadScript
For all you googlers out there, I ended up rolling my own by borrowing some Ext code:
var injectScriptElement = function(id, url, onLoad, onError, scope) {
var script = document.createElement('script'),
documentHead = typeof document !== 'undefined' && (document.head || document.getElementsByTagName('head')[0]),
cleanupScriptElement = function(script) {
script.id = id;
script.onload = null;
script.onreadystatechange = null;
script.onerror = null;
return this;
},
onLoadFn = function() {
cleanupScriptElement(script);
onLoad.call(scope);
},
onErrorFn = function() {
cleanupScriptElement(script);
onError.call(scope);
};
// if the script is already loaded, don't load it again
if (document.getElementById(id) !== null) {
onLoadFn();
return;
}
script.type = 'text/javascript';
script.src = url;
script.onload = onLoadFn;
script.onerror = onErrorFn;
script.onreadystatechange = function() {
if (this.readyState === 'loaded' || this.readyState === 'complete') {
onLoadFn();
}
};
documentHead.appendChild(script);
return script;
}
var error = function() {
console.log('error occurred');
}
var init = function() {
console.log('should not get run till the script is fully loaded');
}
injectScriptElement('myScriptElem', 'http://www.example.com/script.js', init, error, this);
From looking at the source it seems to me that you could do it in a bit of a hackish way. Try using Ext.Loader.setPath() to map a bogus namespace to your third party javascript files, and then use Ext.Loader.require() to try to load them. It doesn't look like ExtJS actually checks if required class is defined in the file included.
