I am using Quill.js to have users create custom user designed pages off the main web page. I have a custom slider that I have written in javascript that will take images and rotate through them. I have the toolbar in quill setup to be able to click on the toolbar to setup the slider in a modal window.
When the user clicks to close the modal slider setup window, I'm trying to insert an edit button in the html editor where the cursor sits so the user can edit the information that was just entered or possible delete the button by removing all the information in the slider modal window.
I have written custom blots, followed all the examples I could find and nothing worked. I did get a custom html tag to show, but not a button. When I requested the html from quill when I setup the custom html tag in the editor, all I get is "" from quill.root.innerHTML none of the custom tag or the information in it even though I see it correctly in the editor.
I would like a button in the editor to make it easy to edit the slider data, as there could be more than one. I am not going to limit the number of sliders. It is up to the user to ruin their own page.
I will not be rendering the slider in the edit html window, just trying to display a button to click on. I do give the user a preview button on the modal window to view the slider if they so choose.
I also would like to store the setup information of the slider in a data tag in json format in the button and change that html button to a tag along with the json data when rendering the html in the browser window.
Can this be done in Quill.js?
I did this by using the import blots embed. I don't register as a button but clicking on the blot I do get a link to the embedded data and trigger the edit of the carousel data on that click.
var Quill;
const BlockEmbed = Quill.import("blots/block/embed");
const Link = Quill.import('formats/link');
class Carousel extends BlockEmbed {
static create(value) {
var self = this;
const node = super.create(value);
node.dataset.carousel = JSON.stringify(value);
value.file.frames.forEach(frame => {
const frameDiv = document.createElement("div");
frameDiv.innerText = frame.title;
frameDiv.className += "previewDiv";
node.appendChild(frameDiv);
});
node.onclick = function () {
if (Carousel.onClick) {
Carousel.onClick(self, node);
}
};
return node;
}
static value(domNode) {
return JSON.parse(domNode.dataset.carousel);
}
static onClick: any;
static blotName = "carousel";
static className = "ql-carousel";
static tagName = "DIV";
}
Quill.register("formats/carousel", Carousel);
I then include this as a script on the page where quill is editing the HTML
<script src="~/js/quilljs-carousel.js"></script>
And then this is the custom javascript to handle the events of the blot displayed in a custom modal dialog in a hidden div tag
<script>
function CarouselClicked(blot, node) {
editCarousel(JSON.parse(node.dataset.carousel), node);
}
var Carousel = Quill.import("formats/carousel");
Carousel.onClick = CarouselClicked;
function carouselToolbarClickHandler() {
createCarousel();

Toolbar.DEFAULTS.handlers.carousel = carouselToolbarClickHandler;

So, in plain terms I am creating a Chrome Extension that so far can only save links from the internet but not delete them. What I want to add is a "remove" button for deleting unwanted links. So far I haven't got that to work.
The buttons I want to remove are added using JavaScript. Each new block of HTML features a "remove" button but clicking that button does nothing. I have tried binding listeners to each element using a for loop but that doesn't seem to work.
The code runs without errors and I'm certain that the issue is a slight oversight but I have only just started using JavaScript so I'm lost for solutions at the moment.
I have included all the code because I don't want to leave out anything that might be imperative to finding a solution.
It starts with the code for adding a link, followed by removing a single link and then removing all links at once. Thank you all for any help, really want to get this working.
https://github.com/mmmamer/Drop Repository for the rest of the code. Mainly popup.html and popup.css.
var urlList = [];
var i = 0;
document.addEventListener('DOMContentLoaded', function() {
getUrlListAndRestoreInDom();
// event listener for the button inside popup window
document.getElementById('save').addEventListener('click', addLink);
});
function addLink() {
var url = document.getElementById("saveLink").value;
addUrlToListAndSave(url);
addUrlToDom(url);
}
function getUrlListAndRestoreInDom() {
chrome.storage.local.get({
urlList: []
}, function(data) {
urlList = data.urlList;
urlList.forEach(function(url) {
addUrlToDom(url);
});
});
}
function addUrlToDom(url) {
// change the text message
document.getElementById("saved-pages").innerHTML = "<h2>Saved pages</h2>";
var newEntry = document.createElement('li');
var newLink = document.createElement('a');
var removeButton = document.createElement('button');
removeButton.textContent = "Remove";
//removeButton.createElement('button');
removeButton.type = "button";
removeButton.className = "remove";
newLink.textContent = url;
newLink.setAttribute('href', url);
newLink.setAttribute('target', '_blank');
newEntry.appendChild(newLink)
newEntry.appendChild(removeButton);
newEntry.className = "listItem";
document.getElementById("list").appendChild(newEntry);
}
function addUrlToListAndSave(url) {
urlList.push(url);
saveUrlList();
//}
}
function saveUrlList(callback) {
chrome.storage.local.set({
urlList
}, function() {
if (typeof callback === 'function') {
//If there was no callback provided, don't try to call it.
callback();
}
});
}
// remove a single bookmark item
document.addEventListener('DOMContentLoaded', function() {
getUrlListAndRestoreInDom();
var allButtons = document.getElementsByClassName('remove');
function listenI(i) {
allButtons[i].addEventListener('click', () => removeMe(i));
}
for (var i = 0; i < allButtons.length; i++) {
listenI(i);
}
});
function removeMe(i) {
var fullList = documents.getElementsByClassName('listItem');
listItem[i].parentNode.removeChild(listItem[i]);
}
//remove all button
document.addEventListener('DOMContentLoaded', function() {
document.getElementById("remove-all").addEventListener('click', function() {
var removeList = document.getElementsByClassName("listItem");
while(removeList[0]) {
removeList[0].parentNode.removeChild(removeList[0]);
}
})
});
chrome.storage.local.get() is asynchronous. So when you try to add the event listeners to the Remove buttons, they're not in the DOM yet.
You can add the listener in the addUrlToDom() function instead. That way you'll also add the event listener when you create new buttons.
function addUrlToDom(url) {
// change the text message
document.getElementById("saved-pages").innerHTML = "<h2>Saved pages</h2>";
var newEntry = document.createElement('li');
var newLink = document.createElement('a');
var removeButton = document.createElement('button');
removeButton.textContent = "Remove";
//removeButton.createElement('button');
removeButton.type = "button";
removeButton.className = "remove";
newLink.textContent = url;
newLink.setAttribute('href', url);
newLink.setAttribute('target', '_blank');
newEntry.appendChild(newLink)
newEntry.appendChild(removeButton);
removeButton.addEventListener("click", function() {
var anchor = this.previousElementSibling;
var url = anchor.getAttribute("href");
removeUrlAndSave(url);
this.parentNode.remove();
});
newEntry.className = "listItem";
document.getElementById("list").appendChild(newEntry);
}
function removeUrlAndSave(url) {
var index = urlList.indexOf(url);
if (index != -1) {
urlList.splice(index, 1);
saveUrlList();
}
}
I'm creating a medical assessment and there is this page where you can select the body parts which are in pain. Once you click on a body part, the name of it will be displayed below. The problem is it will display multiple times when clicked repeatedly. Is there a way to block the click event from repeating?
Here is the sample.
http://jsfiddle.net/qpmxnv2g/6/
var map = document.getElementById("Map");
map.addEventListener("click", function (e) {
callAction(e.target);
});
map.one("click", function (e) {
callAction(e.target);
});
var body = [];
document.getElementById("body").innerHTML = body;
function callAction(area) {
body.push(area.title);
document.getElementById("body").value = body;
}
document.getElementById("Clear").addEventListener('click', function () {
body.length = 0;
document.getElementById("body").value = '';
});
change your function like this:-
function callAction(area) {
if (body.indexOf(area.title) !== -1) { return; }
body.push(area.title);
document.getElementById("body").value = body;
}
Demo
I have this js to show a popup:
oauthpopup.js:
popup.show = function(options) {
this.destination_ = options.destination;
this.windowOptions_ = options.windowOptions;
this.closeCallback_ = options.closeCallback;
this.win_ = null;
this.win_ = window.open(this.destination_, "_blank", this.windowOptions_);
if (this.win_) {
// Poll every 100ms to check if the window has been closed
var self = this;
var closure = function() {
self.checkClosed_();
};
this.timer_ = window.setInterval(closure, 100);
}
return false;
};
popup.checkClosed_ = function() {
if ((!this.win_) || this.win_.closed) {
this.handleApproval_();
}
};
popup.handleApproval_ = function() {
if (this.timer_) {
window.clearInterval(this.timer_);
this.timer_ = null;
}
if (this.win_) {
this.win_.close();
//this.win_ = null;
}
try {
console.log(this.win_.document);
if (this.win_.document.scripts[0].innerHTML === 'window.close();') {
this.closeCallback_();
};
} catch (ex) { }
this.win_ = null;
return false;
};
page script
popup.show({destination: '/auth/' + channel, windowOptions: 'location=0,status=0',
closeCallback:function() {
switchView(divToShow);
}
});
function switchView(divtoShow) {
$("#" + divtoShow).addClass("hidden");
$("#" + divtoShow).removeClass("hidden");
};
It works perfectly in Chrome and Firefox, but in IE this line: this.win_.document.scripts[0].innerHTML doesn't works, I put this in a alert() but nothing happens.
EDIT:
The script tag 'window.close();' is rendered from rails controller in a html page.
The html page close the popup when is rendered, the popup is for twitter and google authentication.
How I can execute the callback after the page is rendered and it is closed?
I'm using a background player that works like this:
function Background(flashID) {
this.flashID = flashID;
this.swfRef = null;
this.onReady = function() { };
this.registerswfRef = function() {
if (this.swfRef == null)
this.swfRef = swfobject.getObjectById(this.flashID);
};
this.playMovieByNum = function(movieID) {
this.registerswfRef();
this.swfRef.playMovieByNum(movieID);
};
And this order to call the video:
var background = new Background('back_1');// id for the backgground movie
function onReady(id)
{
//this function will run when the background has finished loading the xml.
//console.log('backgorund is now ready '+id); // id is passed from flash file.
};
window.onload =function()
{
document.getElementById('video1').onclick=function(){background.start(); background.playMovieByNum(1); };
document.getElementById('video2').onclick=function(){background.start(); background.playMovieByNum(2); };
document.getElementById('video3').onclick=function(){background.start(); background.playMovieByNum(3); };
document.getElementById('video4').onclick=function(){background.start(); background.playMovieByNum(4); };
document.getElementById('video5').onclick=function(){background.start(); background.playMovieByNum(5); };
document.getElementById('video6').onclick=function(){background.start(); background.playMovieByNum(6); };
document.getElementById('video7').onclick=function(){background.start(); background.playMovieByNum(7); };
document.getElementById('video8').onclick=function(){background.start(); background.playMovieByNum(8); };
};
I need the background of the button relative the running video changes color.
For example, if the video "1" is running, the button '#video1' will get the background "#EF4123", if not background is "none".
I tried adding it, but only changes the background when you click on the button:
this.playMovieByNum = function(movieID) {
this.registerswfRef();
this.swfRef.playMovieByNum(movieID);
for(i = 1; i <= 8; i++)
{
if(i == movieID)
$("#video" + i).css("background", "#EF4123");
else
$("#video" + i).css("background", "");
}
};
I need it to change automatically when changing the video also.
