"EXPORTED_SYMBOLS is not an array" Exception flagged when tried to use Components.utils.import("chrome://app/content/app1.js");.
I have a XUL application created and from one of the JS File(say app.js) I tried to include the other JS File as shown above.
Both app.js and app1.js are placed in content folder and also in chrome.manifest file following line is added
"content app content/"
In other JS File (app1.js), I have exported symbols like
var EXPORTED_SYMBOLS = ["Fooinstance"];
var Fooinstance = {
foo: function() {
...
}
}
In app.js,
Components.utils.import("chrome://app/content/app1.js");
// Error: chrome://app/content/app1.js - EXPORTED_SYMBOLS is not an array
...
Fooinstance.foo();
I am running this XUL app on XULRunner 17.0.1 win32 libraries.
I looked through the code in this link https://developer.mozilla.org/en-US/docs/Mozilla/JavaScript_code_modules/Using
It did not help and if I include it as resource it works however I do not want to include it as part of resource.
Could you someone point out what mistake would be ?
I had this same problem, and I solved it:
1) changing the file extension (.js) by .jsm
2) Adding a first line on your module exporting classes to share. EG:
var EXPORTED_SYMBOLS = ["Xobject"];
function Xobject(){
}
Xobject.prototype.stop = function() {
return 'stop';
}
Xobject.prototype.run = function() {
return 'running';
}
3) Calling this way
Components.utils.import('resource://gre/modules/Services.jsm' );
Components.utils.import("chrome://myFirstAddOn/content/Xobject.jsm");
var myXobject = new Xobject();
alert(myXobject.run());
Hope it help u
For anyone else getting this, another possible reason is a circular dependency. My case was a little different, but I had two JSM files each using Components.utils.import to import each other. Then I got this error in one of them.

When I use nuxt to develop my project, I find some problems.
window.__NUXT__=(function(a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y,z,A,B,C,D,E,F,G,H,I,J,K,L,M,N,O,P,Q,R,S,T,U,V,W,X,Y,Z,_,$,aa, ..... code was too larger
can I remove it or use js file to replace it?
I have found a relatively perfect solution. I will share it with you here. You can also take a look at the website I developed using NUXT Sample Website
The key is the hook function vue-renderer:ssr:context, you can set the context.nuxt = null to remove any data in window._NUXT_.
But it is not work well, you have to add serverRender and routePath to window.nuxt
// nuxt.config.js
{
...,
hooks: {
'vue-renderer:ssr:context'(context) {
const routePath = JSON.stringify(context.nuxt.routePath);
context.nuxt = {serverRendered: true, routePath};
}
}
}
You can see the result at my site
I am using a photo gallery component in my project. It requires a path to the folder containing the images. I am unable to find a way to do this. I have created an img directory inside of assets, and I'm using the standard Vue CLI 3 scaffolding. I'm able to use a require('path/to/file/name.png'), but what I need is to be able to bring the whole folder in. I'm unable to figure out a way to do this. I even tried placing the images in a folder inside of public, but no luck.
My structure looks like this:
project/public/img
project/src/assets/img/
project/src/components/
I need to get the project/src/assets/img path into a component inside of project/src/components/componentName.vue.
I should also mention that I want to be able to access this directory from the script tag, not the template tag.
You can try something like this:
const requireModule = require.context('../assets/img.',false,/\.png$/)
const images = {}
requireModule.keys().forEach(filename =>
{
const imageName = fileName.replace(/(\.\/|\.png)/g, '');
images[imageName] = requireModule(fileName)
OR
images[imageName] =
{
namespaced: true,
...requireModule(fileName)
}
});
export default images;
Then you can import this file
import photos from 'imagesObject.js'
for (let key in photos) // do whatever you want with the image
Thank you for your answer IVO. That solution did work, but I found another that I wanted to share here for anyone else having a similar problem. The issue I was having was incorrectly referencing the public folder using a relative path instead of BASE_URL. Based on this...
The public Folder Vue CLI Documentation
I created a directory inside of /public then referenced it using process.env.BASE_URL. This solved the problem. Here are the relevant snippets:
Javascript:
data () {
return {
thumbnailDir : process.env.BASE_URL + 'portfolio/'
}
Template:
<transition-group name="thumbnailfade" tag="div">
<img v-for="thumb in filteredImages"
:key="thumb.id"
#click="showLightbox(thumb.name)"
:src="thumbnailDir + thumb.name"
:alt="thumb.alt"
:title="thumb.alt"/>
</transition-group>
<lightbox id="mylightbox"
ref="lightbox"
:images="images"
:directory="thumbnailDir"
:filter="galleryFilter"
:timeoutDuration="5000"
/>
I have two joomla applications se up with exactly the same versions, the same global configuration settings, and I set up a test application with the following function to load a php into a div on a specific page..
function getDiv(str) {
var id = document.getElementById("appselector").value;
if (id == "") {
document.getElementById("scoffitcategoryedit").innerHTML = "";
return;
}
else {
if (window.XMLHttpRequest) {
// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp3 = new XMLHttpRequest();
} else {
// code for IE6, IE5
xmlhttp3 = new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp3.onreadystatechange = function() {
if (xmlhttp3.readyState == 4 && xmlhttp3.status == 200) {
document.getElementById("scoffitcategoryedit").innerHTML = xmlhttp3.responseText;
alert("WTF");
}
};
xmlhttp3.open("GET","index.php?option=com_jumi&fileid=23& format=raw&" + str + id, true);
xmlhttp3.send();
}
}
I know its a little long winded, but the problem is that the script works fine in one website, but not in the other. Both of them are loading the same versions of jquery (which as you can see I don't like using), and both have the same templates. The only clue I seem to have found is that when I have text links elsewhere on the site attached with query statements pointing to self (index.php?blastr=bla&drivelstr=drivel), the browser shows index.php/ prepended to the link mentioned above.
I debugged the script and in the non functioning website it hangs on the xmlhttp3.send line.
I know people espouse the beauty of jquery's load() function as a replacement for this, but I cant get it to work (probably because the templates are using jquery versions higher than 1.8.1 when it was deprecated). So i'd rather stick with base js.
Any ideas about this inconsistent behaviour ?
This should be a comment but can't yet :(
I would check your configuration file for this line:
public $live_site = '';
and see if there is something in the failing site besides ''.
I found out what it was, I must have actually installed two different versions of the Jumi application in my websites. one website had a file under components/com_jumi/views/application named view.raw.php while the other did not. This meant that the format=raw in the index.php string could not be interpreted and caused a null response.
I simply copied the file into the other website where it was missing and everything then worked fine. But thanks for the response.
I have a small problem.
I have index.js
var loc = require('location');
function doClick (){
loc.doIt();
}
in location.js I have these
var dee = 12;
exports.doIt = function() {
alert(dee);
};
Which means that when I click on the button I can get the alert, however, I want to reach these information without a need of click - onLoad - besides I want to return two values not only one.
How I can fix this maybe it has really an easy solution but because I have been working for a while my mind stopped working :)
regards
you should move your location.js to inside app/lib (as module). for example :
// app/lib/helper.js
exports.callAlert = function(text) {
alert('hello'+ text);
}
and then call it in your controller like this :
var helper = require("helper"); // call helper without path and .js extension
helper.callAlert('Titanium');
and your problem should be solved :)
I am making Titanium mobile project where I want to make one global function which I can use throughout the application. For that I have created other .JS file where I have defined the function and I am including that .JS file where I need to use this function and I am successfully able to call the function.
But My question is :
Can I create new Window in that function? As I have added one Label and one MapView in that window but it is not showing, while at the start of function I have added alert('FunctionCalled'), it is showing me alert but not showing me the label I have added in the window.
So anybody can help me to find out whether we can open window through function. If yes then any sample example, so that I can find out what mistake I am making.
Thanks,
Rakesh Gondaliya
you approach CAN work but is not a best practice, you should create a global namespace, add the function to that namespace and then only include the file with the function once in app.js
// apps.js
var myApp = {};
Ti.include('global.js','ui.js');
myApp.ui.openMainWindow();
then we create a seperate file for our ui functions
//ui.js
(function(){
var ui = {};
ui.openMainWindow = function() {
// do open window stuff
// call global function
myApp.global.globalFunction1();
}
myApp.ui = ui;
})();
here is where we create our global functions, we will not have to include the file everywhere since we are adding it to our global namespace
//global.js
(function(){
var global = {};
global.globalFunction1 = function() {
// do super global stuff
}
myApp.global = global;
})();
this is a simple outline of how it can be implemented, I have a complete code listing on my blog
Yes you can create a new window or add a label or anything else. If you wanted to add a label to the current window then you would do:
var helloWorld = Ti.UI.createLabel({ text: "Hello World", height: "auto", width: 200 });
Ti.UI.currentWindow.add(helloWorld);
It won't matter where the code is executing because Ti.UI.currentWindow will be the active window regardless.
