I'm trying to use one function and a lot of IF functions to run this code.
I'm going to make this as a note app.
I want to add an IF function that has an class called stop-note.
I want to add it in the notes list for it's IF function then I want to add it to the "renderNotes" for it's link like style.
notesList.on('click', function (e) {
e.preventDefault();
var target = $(e.target);
var abort = false;
// Listen to the selected note.
if (target.hasClass('listen-note')) {
if (abort) {
return;
}
var content = target.closest('.note').find('.content').text();
readOutLoud(content);
}
//Edit Note
if (target.hasClass('edit-note')) {
editText(content);
var dateTime = target.siblings('.date').text();
deleteNote(dateTime);
target.closest('.note').remove();
var content = target.closest('.note').find('.content').text();
}
// Delete note.
if (target.hasClass('delete-note')) {
var dateTime = target.siblings('.date').text();
deleteNote(dateTime);
target.closest('.note').remove();
}
});
This is my function that runs my function above.
function renderNotes(notes) {
var html = '';
if (notes.length) {
notes.forEach(function (note) {
html += `<li class="note">
<p class="header">
<span class="date">${note.date}</span>
Listen
Edit
html = <button class="stop-note" onclick="abort = true">Stop</button>
Delete
</p>
<p class="content">${note.content}</p>
</li>`;
});
} else {
html = '<li><p class="content">You don\'t have any notes yet.</p></li>';
}
notesList.html(html);
}
abort is a local variable, and you set it to false whenever they click on a note list. So onclick="abort = true" has no effect on the variable that's being tested in the function.
You need to make it a global variable.
window.abort = false;
notesList.on('click', function (e) {
e.preventDefault();
var target = $(e.target);
// Listen to the selected note.
if (target.hasClass('listen-note')) {
if (abort) {
return;
}
var content = target.closest('.note').find('.content').text();
readOutLoud(content);
}
//Edit Note
if (target.hasClass('edit-note')) {
editText(content);
var dateTime = target.siblings('.date').text();
deleteNote(dateTime);
target.closest('.note').remove();
var content = target.closest('.note').find('.content').text();
}
// Delete note.
if (target.hasClass('delete-note')) {
var dateTime = target.siblings('.date').text();
deleteNote(dateTime);
target.closest('.note').remove();
}
});

I have a trouble with jquery trigger click. I need to play audio from audio tag via trigger click. When i click first time on first element it work, but if I click in another element, the first click not work. If i click 2nd time it will be work.
var Audioplaying = false;
jQuery('.playAudio').click(function(e) {
var playerID = jQuery(this).next('.audioPlayer').attr('id');
var playerBTN = jQuery(this);
if (Audioplaying == false) {
Audioplaying = true;
jQuery("#"+playerID)[0].play();
playerBTN.addClass('play');
} else {
Audioplaying = false;
jQuery("#"+playerID)[0].pause();
playerBTN.removeClass('play');
}
e.preventDefault();
});
The variable Audioplaying is shared, it is not unique so you probably want it to be unique per element. So use data() to keep track of the state for each player.
jQuery('.playAudio').click(function(e) {
var player = jQuery(this).next('.audioPlayer');
var playerID = player.attr('id');
var playerState = player.data('isPlaying') || false; // get if it is running
player.data('isPlaying', !playerState); // update the boolean
var playerBTN = jQuery(this);
if (!playerState) {
jQuery("#"+playerID)[0].play();
playerBTN.addClass('play');
} else {
jQuery("#"+playerID)[0].pause();
playerBTN.removeClass('play');
}
e.preventDefault();
});
Maintain the state of each button separately. so, you can use an object with it's 'id' as the key.
example : { button_id : true/false }
var Audioplaying = {};
jQuery('.playAudio').click(function(e) {
var playerID = jQuery(this).next('.audioPlayer').attr('id');
var playerBTN = jQuery(this);
if (!Audioplaying[playerID]) {
Audioplaying[playerID] = true; // every button has it's own state maintained in the object.
jQuery("#"+playerID)[0].play();
playerBTN.addClass('play');
} else {
Audioplaying[playerID] = false;
jQuery("#"+playerID)[0].pause();
playerBTN.removeClass('play');
}
e.preventDefault();
});
Hope it helps you arrive at a optimal solution.
Hey guys I need just a little bit of help with this.
So I have modal boxes hiding on my page and when I click on them using the video platform VERSE they work perfectly.
My questions is: How can I call the same modal boxes if I wan to call them from a regular link or button on the page.
Here is the sample:
http://digitalfeast.com/clients/nccv/ncc-verse.html
Here is my Javascript code:
(function() {
(function() {
window.onload = function() {
var frame = document.getElementsByName("verse-iframe")[0].contentWindow;
// Variables below (i.e. "menu-1") reference div id from your markup
function receiveMessage(event) {
var data = (typeof event.data === "String") ? JSON.parse(event.data) : event
var modalWindow1 = document.getElementById("ruben-1");
var modalWindow2 = document.getElementById("ruben-2");
var modalWindow3 = document.getElementById("menu-3");
var modalWindow4 = document.getElementById("menu-4");
// Variables below (i.e. "menu-1") reference the unique callback names entered for your hotspots in the Verse editor
if (data.data["identifier"] === "ruben-1") {
modalWindow1.style.display = "block";
}
if (data.data["identifier"] === "ruben-2") {
modalWindow2.style.display = "block";
}
if (data.data["identifier"] === "menu-3") {
modalWindow3.style.display = "block";
}
if (data.data["identifier"] === "menu-4") {
modalWindow4.style.display = "block";
}
}
var closeBtns = document.getElementsByClassName("modal-close");
for (var i = 0; i < closeBtns.length; i++) {
var btn = closeBtns[i];
btn.onclick = function (event) {
event.target.parentNode.parentNode.style.display = "none";
frame.postMessage({action: "play"}, "*");
};
}
window.addEventListener('message', receiveMessage);
var frame = document.getElementsByName("verse-iframe")[0].contentWindow;
};
}());
}());
Given your code, all you need to do is send the window a message using the Messaging API inside your button click handler.
Your event listener will then execute the receiveMessage function and open your model for ruben-1.
window.onload = () => {
document.querySelector('[data-modal="ruben-1"]').addEventListener("click", (e) => {
let postData = {
identifier: e.target.dataset.modal
};
window.postMessage(postData, "*");
});
window.addEventListener('message', m => {
alert(m.data.identifier);
});
}
<button data-modal="ruben-1">Ruben-1 Video</button>
I am revisiting this code I made a year ago with the help of another person. Unfortunately I don't have contact with them anymore to get more help. Basically It dynamically adds classs to the tb and b nodes of a document coming from namesToChange. Now what I am trying to do is append some text to the div with class dtxt node but still use this code below. I am using the code $('td.pn_adm_jeff').children('div.dtxt').append('zzz'); and it works but it constantly appends more than once as seen in the photo below. How do I go about making it add once and stop?

Code
function customizefields(a) {
$('td b').each(function () {
name = $(this).text();
if (name.indexOf(" ") != -1) {
name = name.substring(0, name.indexOf(" "))
}
if (a[name]) {
this.className = a[name].class;
this.parentNode.className = a[name].img
}
})
$('td.pn_adm_jeff').children('div.dtxt').append('zzz');
}
var namesToChange = {
'Jeff' :{'class':'pn_adm','img':'pn_adm_jeff'}
};
setInterval(function () {
customizefields(namesToChange)
}, 1000);
Update
var needsUpdate = true;
function customizefields(a) {
$('td b').each(function () {
name = $(this).text();
if (name.indexOf(" ") != -1) {
name = name.substring(0, name.indexOf(" "));
}
if (a[name]) {
this.className = a[name].class;
this.parentNode.className = a[name].img;
}
});
if (needsUpdate) {
$('td.pn_adm_jeff').children('div.dtxt').append('testing');
needsUpdate = false;
}
}
var namesToChange = {
'jeff' :{'class':'pn_adm','img':'pn_adm_jeff'};
};
setTimeout(function () {
customizefields(namesToChange);
}, 1000);
use setTimeout rather than setInterval (interval is for repeating a timer task, timeout is a single timer task)
To prevent a certain task from occuring more than once in a repeated task, there is a simple fix.
// global variable
var needsUpdate = true;
// now in the timer task
if (needsUpdate) {
$('td.pn_adm_jeff').children('div.dtxt').append('zzz');
needsUpdate = false;
}
Does that work for you?
Define a global variable to hold the input flag
var appended = false;
function appendthestring() {
if(!appended) $('td.pn_adm_jeff').children('div.dtxt').append('zzz');
appended = true;
}
I'm trying to add some functionality to be able to edit comments inline. So far it's pretty close, but I'm experiencing issues trying to trigger a second event. It works the first time, but after that, fails.
$(function() {
var $editBtn = $('.js-edit-comment-btn');
var clicked = false;
$editBtn.on('click', $editBtn, function() {
clicked = true;
var $that = $(this);
var $form = $that.closest('.js-edit-comment');
var $commentTextBody = $that.closest('div').find('.js-comment-body');
var commentText = $commentTextBody.text();
var $editableText = $('<textarea />');
if ($that.text() === 'Save Edits') {
$that.text('Saving...').attr('disabled', true);
} else {
$that.text('Save Edits').attr('alt', 'Save your edits');
}
// Replace div with textarea, and populate it with the comment text
var makeDivTextarea = function($editableText, commentText, $commentTextBody) {
$editableText.val(commentText);
$commentTextBody.replaceWith($editableText);
$editableText.addClass('gray_textarea js-edited-comment').width('100%').css('padding', '4px').focus();
};
makeDivTextarea($editableText, commentText, $commentTextBody);
var saveEdits = function($that, $editableText) {
$that.on('click', $that, function() {
if (clicked) {
var comment = $that.closest('div').find('.js-edited-comment').val();
$editableText.wrap('<div class="js-comment-body" />').replaceWith(comment);
$that.text('Edit').attr('alt', 'Edit Your Comment').attr('disabled', false);
$('#output').append('saved');
clicked = false;
return false;
}
});
};
saveEdits($that, $editableText);
return false;
});
});
jsfiddle demo here
Hiya demo for your working solution: http://jsfiddle.net/8P6uz/
clicked=true was the issue :)) I have rectified another small thing. i.e. $('#output') is set to empty before appending another saved hence text **saved** will only appear once.
small note: If I may suggest use Id of the button or if there are many edit buttons try using this which you already i reckon; I will see if I can write this more cleaner but that will be sometime latter-ish but this should fix your issue. :) enjoy!
Jquery Code
$(function() {
var $editBtn = $('.js-edit-comment-btn');
var clicked = false;
$editBtn.on('click', $editBtn, function() {
clicked = true;
var $that = $(this);
var $form = $that.closest('.js-edit-comment');
var $commentTextBody = $that.closest('div').find('.js-comment-body');
var commentText = $commentTextBody.text();
var $editableText = $('<textarea />');
if ($that.text() === 'Save Edits') {
$that.text('Saving...').attr('disabled', true);
} else {
$that.text('Save Edits').attr('alt', 'Save your edits');
}
// Replace div with textarea, and populate it with the comment text
var makeDivTextarea = function($editableText, commentText, $commentTextBody) {
$editableText.val(commentText);
$commentTextBody.replaceWith($editableText);
$editableText.addClass('gray_textarea js-edited-comment').width('100%').css('padding', '4px').focus();
};
makeDivTextarea($editableText, commentText, $commentTextBody);

var comment = $that.closest('div').find('.js-edited-comment').val();
$editableText.wrap('<div class="js-comment-body" />').replaceWith(comment);

I have some jQuery plugin that changes some elements, i need some event or jQuery plugin that trigger an event when some text input value changed.
I've downloaded jquery.textchange plugin, it is a good plugin but doesn't detect changes via external source.
#MSS -- Alright, this is a kludge but it works:
When I call boxWatcher() I set the value to 3,000 but you'd need to do it much more often, like maybe 100 or 300.
http://jsfiddle.net/N9zBA/8/
var theOldContent = $('#theID').val().trim();
var theNewContent = "";
function boxWatcher(milSecondsBetweenChecks) {
var theLoop = setInterval(function() {
theNewContent = $('#theID').val().trim();
if (theOldContent == theNewContent) {
return; //no change
}
clearInterval(theLoop);//stop looping
handleContentChange();
}, milSecondsBetweenChecks);
};
function handleContentChange() {
alert('content has changed');
//restart boxWatcher
theOldContent = theNewContent;//reset theOldContent
boxWatcher(3000);//3000 is about 3 seconds
}
function buttonClick() {
$('#theID').value = 'asd;lfikjasd;fkj';
}
$(document).ready(function() {
boxWatcher(3000);
})
try to set the old value into a global variable then fire onkeypress event on your text input and compare between old and new values of it. some thing like that
var oldvlaue = $('#myInput').val();
$('#myInput').keyup(function(){
if(oldvlaue!=$('#myInput').val().trim())
{
alert('text has been changed');
}
});
you test this example here
Edit
try to add an EventListner to your text input, I don't know more about it but you can check this Post it may help
Thanks to #Darin because of his/her solution I've marked as the answer, but i have made some small jQuery plugin to achieve the same work named 'txtChgMon'.
(function ($) {
$.fn.txtChgMon = function (func) {
var res = this.each(function () {
txts[0] = { t: this, f: func, oldT: $(this).val(), newT: '' };
});
if (!watchStarted) {
boxWatcher(200);
}
return res;
};
})(jQuery);
var txts = [];
var watchStarted = false;
function boxWatcher(milSecondsBetweenChecks) {
watchStarted = true;
var theLoop = setInterval(function () {
for (var i = 0; i < txts.length; i++) {
txts[i].newT = $(txts[i].t).val();
if (txts[i].newT == txts[i].oldT) {
return; //no change
}
clearInterval(theLoop); //stop looping
txts[i].f(txts[i], txts[i].oldT, txts[i].newT);
txts[i].oldT = $(txts[i].t).val();
boxWatcher(milSecondsBetweenChecks);
return;
}
}, milSecondsBetweenChecks);
}
