I want my extension to open up in the form of an iframe instead of the normal popup window. I've been able to achieve this so far. Now I'm trying to make this iframe draggable using jQuery UI but unable to do so. My code for inject.js is as below:
function toggleVisisbility (node) {
node.style.display = (node.style.display === 'none' || node.style.display === '') ? 'block' : 'none'
}
function appendIframe(app) {
var iframe = document.createElement('iframe');
iframe.id = 'popup-app';
iframe.style.cssText = 'position:absolute;top:0;right:0;display:block;' +
'width:350px;height:500px;z-index:99999999;' +
'border: none;' +
'box-shadow: 0px 8px 16px rgba(0,0,0,0.25);';
chrome.storage.local.get("logged_in", function(data) {
if(data.logged_in) {
iframe.src = chrome.runtime.getURL('./html/loggedPopup.html')
} else {
iframe.src = chrome.runtime.getURL('./html/popup.html')
}
});
app.appendChild(iframe)
}
function insertIframe(anchor) {
let app = Array.from(anchor.childNodes).find(function(node){ return node.id === 'popup-app'})
if (app) {
if (app.querySelectorAll('iframe').length === 0) {
appendIframe(app)
}
toggleVisisbility(app)
} else {
appendIframe(anchor)
}
}
var extensionOrigin = 'chrome-extension://' + chrome.runtime.id
if (!location.ancestorOrigins.contains(extensionOrigin)) {
var anchor = document.getElementById('cfp-anchor')
if (anchor) {
insertIframe(anchor)
} else {
const AppRoot = document.createElement('div', { id: 'cfp-anchor' });
AppRoot.id = 'cfp-anchor';
const body = document.getElementsByTagName('body')[0];
body.appendChild(AppRoot);
AppRoot.innerHTML = '';
insertIframe(AppRoot)
}
}
I figured out the solution. I used a div instead of an iframe, made the div draggable and then loaded my html inside the div. I used the following code:
function appendIframe(app) {
var draggableDiv = document.createElement('div');
draggableDiv.id = 'popup-app';
draggableDiv.className = 'draggable';
draggableDiv.setAttribute('data-draggable', 'true');
draggableDiv.style.cssText = 'position:fixed;top:16px;right:21px;display:block;' +
'width:350px;height:500px;z-index:99999999;' +
'border: none; cursor: move;' +
'box-shadow: 0px 8px 16px rgba(0,0,0,0.25);' +
'background: #25BAF1;';
chrome.storage.local.get("logged_in", function(data) {
if(data.logged_in) {
document.getElementById("popup-app").innerHTML='<object id="overlay" style="width: 100%; height: 100%; position: absolute; top: 25px" type="text/html" data='+chrome.runtime.getURL('./html/loggedPopup.html')+' ></object>';
} else {
document.getElementById("popup-app").innerHTML='<object id="overlay" style="width: 100%; height: 100%; position: absolute; top: 25px" type="text/html" data='+chrome.runtime.getURL('./html/popup.html')+' ></object>';
}
});
$("#popup-app").addClass(".draggable");
makeDivDraggable();
app.appendChild(draggableDiv)
}
function makeDivDraggable(){
$(document).ready(function() {
var $body = $('body');
var $target = null;
var isDraggEnabled = false;
$body.on("mousedown", "div", function(e) {
$this = $(this);
isDraggEnabled = $this.data("draggable");
if (isDraggEnabled) {
if(e.offsetX===undefined){
x = e.pageX-$(this).offset().left;
y = e.pageY-$(this).offset().top;
}else{
x = e.offsetX;
y = e.offsetY;
}
$this.addClass('draggable');
$body.addClass('noselect');
$target = $(e.target);
}
});
$body.on("mouseup", function(e) {
$target = null;
$body.find(".draggable").removeClass('draggable');
$body.removeClass('noselect');
});
$body.on("mousemove", function(e) {
if ($target) {
$target.offset({
top: e.pageY - y,
left: e.pageX - x
});
}
});
});
}
What this basically does is create a div, which is draggable and then sticks up another layer of html on top. The modified position allows to grab the div from the top and then move it around.

I tried to use subclassing as shown in the example at http://fabricjs.com/polaroid.
The PolaroidPhoto subclass just adds a border on the image as shown on the following fiddle: https://jsfiddle.net/gusy54rr/6/
canvas = this.__canvas = new fabric.Canvas('c', {
backgroundColor: '#333',
HOVER_CURSOR: 'pointer'
});
var PolaroidPhoto = fabric.util.createClass(fabric.Image, {
H_PADDING: 20,
V_PADDING: 20,
originX: 'center',
originY: 'center',
initialize: function(src, options) {
this.callSuper('initialize', options);
this.image = new Image();
this.image.src = src;
console.log("In initialize, src is:" + src);
this.image.onload = (function() {
this.width = this.image.width;
this.height = this.image.height;
this.loaded = true;
this.setCoords();
this.fire('image:loaded');
}).bind(this);
},
_render: function(ctx) {
if (this.loaded) {
ctx.fillStyle = '#fff';
ctx.fillRect(
-(this.width / 2) - this.H_PADDING,
-(this.height / 2) - this.H_PADDING,
this.width + this.H_PADDING * 2,
this.height + this.V_PADDING * 2);
ctx.drawImage(this.image, -this.width / 2, -this.height / 2);
}
}
});
var photo = new PolaroidPhoto('https://i.stack.imgur.com/cqmQ9.png', { });
photo.on('image:loaded', canvas.renderAll.bind(canvas));
photo.set('scaleX', 1);
photo.set('scaleY', 1);
photo.set('top', 180);
photo.set('left', 150);
console.log("photo,src is :" + photo.get('src'));
// forcing src value (but ineffective)
photo.set('src', 'https://i.stack.imgur.com/cqmQ9.png');
canvas.add(photo);
canvas.add(
rect= new fabric.Rect({ top: 50, left: 100, width: 50, height: 50, fill: '#f55' }),
circle = new fabric.Circle({ top: 140, left: 230, radius: 75, fill: 'green' }),
triangle = new fabric.Triangle({ top: 300, left: 210, width: 100, height: 100, fill: 'blue' })
);
$("#group").on('click', function() {
var activegroup = canvas.getActiveGroup();
var objectsInGroup = activegroup.getObjects();
activegroup.clone(function(newgroup) {
canvas.discardActiveGroup();
objectsInGroup.forEach(function(object) {
canvas.remove(object);
});
canvas.add(newgroup);
});
});
$("#ungroup").click(function(){
var activeObject = canvas.getActiveObject();
if(activeObject.type=="group"){
var items = activeObject._objects;
alert(items);
activeObject._restoreObjectsState();
canvas.remove(activeObject);
for(var i = 0; i < items.length; i++) {
canvas.add(items[i]);
items[i].dirty = true;
canvas.item(canvas.size()-1).hasControls = true;
}
canvas.renderAll();
}
});
It works fine until I want to stringify or make some grouping with a subclassed object.
In the fiddle, I completed the Fabric demo's example by adding a few basis objects (a rectangle, a circle and a triangle).
If I select the subclassed image and any other object and then click on the group button:
The image disappears.
The scr property of the photo is not set (as shown by the alert on "ungroup" for the former group).
A stringification of the canvas also shows that "src" is missing.
Even if I force (see the fiddle) a src value using "photo.set('src',...)" :
- the grouping still makes the picture to disappear.
- The stringification still lacks the "src" attribute. (I tried to extend toObjects to no avail)
How to get grouping and stringification to work with subclassed objects?
Thanks for your help.
Here is a new jsfiddle showing correct grouping and JSON load with a sub-classed (PolaroidPhoto) image. Fabric version is 1.7.19
https://jsfiddle.net/rpzk7wL6/2/
I put some comments in the code to show my modifications.
The main problem in the former script was the absence of fromObjects() method.
I also added a handler listening to "image:loaded" to the sub-class instance created
by fromObjects, in order to render it after loading .
fabric.Object.prototype.transparentCorners = false;
canvas = this.__canvas = new fabric.Canvas('c', {
backgroundColor: '#333',
HOVER_CURSOR: 'pointer'
});
fabric.Polaroidphoto = fabric.util.createClass(fabric.Image, {

this.width = this.image.width;

this.height = this.image.height;
this.src= this.image.src;
console.log("initialize image.onload, src:" + src);
this.loaded = true;
this.setCoords();
this.fire('image:loaded');
}).bind(this);
},

console.log("_render:is_loaded");
ctx.fillStyle = '#fff';

-(this.width / 2) - this.H_PADDING,

this.width + this.H_PADDING * 2,
this.height + this.V_PADDING * 2);
ctx.drawImage(this.image, -this.width / 2, -this.height / 2);
} else {
console.log("_render:is_NOT__loaded");
}
}
});

I use NodeJS and Socket.io to get data from a database. I now want to fill a google area chart with these data but i kind of fail at doing it.
The data is transmitted as Objects. Each Object contains two values (datetime and value). I append these values to an array and then store them in a DataTable:
google.load('visualization', '1', {
packages: ['corechart']
});
google.setOnLoadCallback(drawChart);
var socket = io();
getData();
function drawChart(dataArray) {
var data = new google.visualization.DataTable();
data.addColumn('string', 'DateTime');
data.addColumn('number', 'Value');
for (var i = 0; i < dataArray.length; i += 2) {
console.log(dataArray[0]);
data.addRow([dataArray[i], dataArray[i + 1]]);
}
var chart = new google.visualization.AreaChart(document.getElementById('chart'));
chart.draw(data, {
title: "Data Visualization",
isStacked: true,
width: '50%',
height: '50%',
vAxis: {
title: 'Data v-Axis'
},
hAxis: {
title: 'Data h-Axis'
}
})
}
function getData() {
socket.emit('GET');
socket.on('serverSent', function (data) {
var processedData = processData(data);
drawChart(processedData);
})
}
function processData(data) {
var arr = new Array();
jQuery.each(data, function (index, object) {
arr.push(object['datetime'], parseInt(object['value']));
})
return arr;
}
If i call my website i see the chart but without any values and the error message `google.visualization.DataTable is not a constructor´. So what am i doing wrong?
The problem is drawChart is being called twice.
From both google.setOnLoadCallback and getData.
If getData is called before google.setOnLoadCallback,
then google.visualization.DataTable will not be recognized.
In addition, it is recommended to use loader.js vs. jsapi.
See Load the Libraries for more info...
As such, please try the following...
Replace...
<script src="https://www.google.com/jsapi"></script>
With...
<script src="https://www.gstatic.com/charts/loader.js"></script>
And try something like...
google.charts.load('current', {
callback: init,
packages: ['corechart']
});
function init() {
var socket = io();
socket.emit('GET');
socket.on('serverSent', function (data) {
var processedData = processData(data);
drawChart(processedData);
});
}
function drawChart(dataArray) {
var data = new google.visualization.DataTable();
data.addColumn('string', 'DateTime');
data.addColumn('number', 'Value');
for (var i = 0; i < dataArray.length; i += 2) {
console.log(dataArray[0]);
data.addRow([dataArray[i], dataArray[i + 1]]);
}
var chart = new google.visualization.AreaChart(document.getElementById('chart'));
chart.draw(data, {
title: "Data Visualization",
isStacked: true,
width: '50%',
height: '50%',
vAxis: {
title: 'Data v-Axis'
},
hAxis: {
title: 'Data h-Axis'
}
})
}

If you want to add multiple lines/blocks when you're writing inline JS/CSS you need to add a .
script.
alert('cannot make a chat room.');
location.href = '/enter';
script(type='text/javascript').
$(document).ready(function() {
var room = io.connect('/room');
How do I create rectangles with 4 ports (each side) in a correct way, so I can save and restore them via JSON?
I tried this one, but only the rectangles are been saved. The connections and labels got lost.
JSFiddle: http://jsfiddle.net/xfvf4/36/
Create two elements (Add) - move them and connect them
Write: This gives the content as JSON-Array
Read: Should make the grafic out of the JSON-Array
The last point doesn't work.
JS:
var LabelRectangle = draw2d.shape.basic.Rectangle.extend({
NAME: "draw2d.shape.basic.Rectangle",
init: function (attr) {
this._super(attr);
this.label = new draw2d.shape.basic.Label({
text: "Text",

this.add(this.label, new draw2d.layout.locator.CenterLocator(this));

});
return memento;
},

Just use the write.js and Reader.js in the "json"-Folder of Draw2D.js 5.0.4 and this code:

// unmarshal the JSON document into the canvas
// (load)
var reader = new draw2d.io.json.Reader();
reader.unmarshal(canvas, jsonDocument);
// display the JSON document in the preview DIV
//
displayJSON(canvas);
// add an event listener to the Canvas for change notifications.
// We just dump the current canvas document into the DIV
//
canvas.getCommandStack().addEventListener(function(e){
if(e.isPostChangeEvent()){
displayJSON(canvas);
}
});
});
function displayJSON(canvas){
var writer = new draw2d.io.json.Writer();
writer.marshal(canvas,function(json){
$("#json").text(JSON.stringify(json, null, 2));
});
}
This should work:
var LabelRectangle = draw2d.shape.basic.Rectangle.extend({

init: function (attr) {
this._super(attr);
this.label = new draw2d.shape.basic.Label({

I'm trying to output something like these:
counter is: 10 <= fixed line and auto updating
console.logs, etc... <= other console.logs, errors, defaul outputs
console.logs, etc...
console.logs, etc...
console.logs, etc...
Is this possible?
I have tried with process.stdout.write() but it is not working.
var counter = 0;
setInterval(function(){
counter++;
process.stdout.write("counter is " + counter + " \r");
}, 500);
setInterval(function(){
console.log('some output');
}, 1500);
Here's an example using blessed:
var blessed = require('blessed');
var screen = blessed.screen(),
body = blessed.box({
top: 1,
left: 0,
width: '100%',
height: '99%'
}),
statusbar = blessed.box({
top: 0,
left: 0,
width: '100%',
height: 1,
style: {
fg: 'white',
bg: 'blue'
}
});
screen.append(statusbar);
screen.append(body);
screen.key(['escape', 'q', 'C-c'], function(ch, key) {
return process.exit(0);
});
function status(text) { statusbar.setContent(text); screen.render(); }
function log(text) { body.insertLine(0, text); screen.render(); }
var c = 1;
setInterval(function() {
status((new Date()).toISOString());
log('This is line #' + (c++));
}, 100);
Here's a simpler example that has almost the same effect (the status bar doesn't fill in extra space with background color):
var screen = blessed.screen(),
body = blessed.box({
top: 0,
left: 0,
width: '100%',
height: '100%',
tags: true
});
screen.append(body);
screen.key(['escape', 'q', 'C-c'], function(ch, key) {
return process.exit(0);
});
function status(text) {
body.setLine(0, '{blue-bg}' + text + '{/blue-bg}');
screen.render();
}
function log(text) {
body.insertLine(1, text);
screen.render();
}
var c = 1;
setInterval(function() {
status((new Date()).toISOString());
log('This is line #' + (c++));
}, 100);
Aside there are a lot of node modules that can help you do this,(blessed, ncurses, ansi, termhelper), for educational purposes you can also do it with vanilla node easily using process.stdout.moveCursor:
var logs = [];
function log(text) {
logs.push(text);
console.log(text);
}
function changeCounter(n) {
