JavaScript - How to know which object has been clicked - javascript

I have a basic film search, now I'm trying to make it so that once you click on a film, it gets just that clicked films title property, at the moment it is bringing every film from the list of films that match the search term.
How do I go about finding out which film has been clicked and ONLY pass this objects properties through instead of every object? Do I need to use a loop?
screenshots added, e.g if I click the first film "John Wick" it creates a h1 title for every film title that has "John Wick"
function search() {
var userInput = $("#content-container-search").val().replace(/\s+/g,"%20");
var searchTerm = "".concat(standardURL, apiKey, 'query=', userInput);
var request = new XMLHttpRequest();
clear(); //runs the clear function to clear existing DOM results to make way for the new ones
request.open('GET', searchTerm , true);
request.onload = function(data) {
var data = JSON.parse(this.response);
createList(data);
}
request.send();
}
function createList(data){
var app = document.getElementById("film-results");
data.results.forEach(film => {
console.log(film.title);
var filmInfo = film;
var Filmcontainer = document.createElement("div");
Filmcontainer.setAttribute("class", "row film-container");
var filmContainerLeftPanel = document.createElement("div");
filmContainerLeftPanel.setAttribute("class", "film-container-left-panel column small-3");
var filmContainerRightPanel = document.createElement("div");
filmContainerRightPanel.setAttribute("class", "film-container-right-panel column small-9");
var li = document.createElement("li");
li.setAttribute("class", "film-container-right-panel-li");
var ul = document.createElement("ul");
var h1 = document.createElement("h1");
h1.setAttribute("class", "film-container-right-panel-h1");
h1.textContent = film.title;
var ahref = document.createElement("a");
// ahref.setAttribute("class", "button");
ahref.setAttribute("data-open", "exampleModal1");
var paragraph = document.createElement("p");
paragraph.setAttribute("class", "film-container-right-panel-p");
var paragraphMaxLength = 125;
var filmOverview = film.overview;
var trimmedFilmOverview = filmOverview.substr(0, paragraphMaxLength);
trimmedFilmOverview = trimmedFilmOverview.substr(0, Math.min(trimmedFilmOverview.length, trimmedFilmOverview.lastIndexOf(" ")));
trimmedFilmOverview = trimmedFilmOverview + "...";
paragraph.textContent = trimmedFilmOverview;
var baseImgURL = "https://image.tmdb.org/t/p/w154" + film.poster_path;
var filmImage = document.createElement("img");
filmImage.src = baseImgURL;
filmImage.setAttribute("class", "film-container-right-panel-img");
// film.forEach(filmImage.src.indexOf("null"))
// filmImage.src = "/img/imagenotavailable.png";
app.appendChild(Filmcontainer);
Filmcontainer.appendChild(filmContainerLeftPanel);
Filmcontainer.appendChild(filmContainerRightPanel);
filmContainerLeftPanel.appendChild(filmImage);
filmContainerRightPanel.appendChild(ul)
.appendChild(li)
.appendChild(ahref)
.appendChild(h1);
li.appendChild(paragraph);
generateModal(filmInfo);
})
}
function generateModal(filmInfo){
var modal = document.getElementById("exampleModal1");
var h1 = document.createElement("h1");
h1.textContent = filmInfo.title;
modal.appendChild(h1);
console.log(filmInfo);
}

Maybe you want to take a look at Event.target and currentTarget.
--UPDATE--
Here is an example:
let ctas = document.querySelectorAll('.see-details');
ctas.forEach(cta => {
cta.addEventListener('click', (movie) => {
let movieId = movie.target.getAttribute('data-movie-id');
console.log(movieId);
});
});
<button data-movie-id="toy-story-1" class="see-details">See movie details</button>

You can solve this problem using event.target in JavaScript.
var div = document.createElement('div');
document.body.appendChild(div);
var button = document.createElement("button");
button.innerHTML = "John Wick";
button.style.margin= "10px";
div.appendChild(button);
var button2 = document.createElement("button");
button2.innerHTML = "John Wick: chapter 2";
button2.style.margin= "10px";
div.appendChild(button2);
var button3 = document.createElement("button");
button3.innerHTML = "John Wick: chapter 3";
div.appendChild(button3);
function showName(e){
alert("you have clicked "+e.target.innerHTML);
}
div.addEventListener('click', showName, false);
In this code I have created 3 buttons and whenever you clicks on any button it will trigger an event showName and event.target helps us to get the element that triggered a specific event (i.e click in our case) .
and try to run console.log(event.target), this will give you the whole information about the event triggered here.
I hope this helps.

How to Remove Particular Element from Array in Javascript with a button

I want to be able to press on my trashcan and be able to delete any todo i want. Right now i can only remove the first index off my todo with with the help off splice. Also when i inspect my array in console i want to be able to use true or false. So when i click on my button my object gets removed from my screen and inside off the array in console it should show that my object indeed have been removed and turns into true instead of false( todoIsRemoved: false). here is a link so you can see all off my code: https://jsfiddle.net/marvstarv/tqdzn8bg/.
this is my class:
let p=0;
let allTheToDos = [];
class Todo{
constructor(toDoItem, removedToDo){
this.Id= p ++;
this.toDoItem = toDoItem;
this.removedToDo = removedToDo;
}
}
this is the function i need help with,
function removeTask (){
let liContainer = document.getElementById ("mySection"); // contains my label(checkmark), Li, and trashcan button.
allTheToDos.splice(Todo,1);
liContainer.innerHTML="";
generateHtml();
console.log(allTheToDos);
}
this function is conected to line 64 off my "main.js": deleteButton.addEventListener('click', () =>{removeTask(allTheToDos[i])});
i appriciate all the help, get back to me if anything was unclear.enter code here
I updated your Js file to:
window.onload = function(){
// without this my site keeps realoding when adding a new item
let firstTask = new Todo ('Bädda sängen',false);
let secondTask = new Todo ('Hänga upp tavlorna',false);
let thirdTask = new Todo ('Kick back & realx',false);
// Adding my premade todo's into my Array that has the variable 'allTheToDos'
allTheToDos.push(firstTask);
allTheToDos.push(secondTask);
allTheToDos.push(thirdTask);
// creating a function so that the user can add a new todo
let addButton = document.getElementById('addBtn');
addButton.addEventListener('click',addNewTask);
generateHtml ();
// let checkedLi = document.getElementById('listItem')
// checkedLi.addEventListener('click',)
console.log(allTheToDos);
}
// my puublic

}
}
function addNewTask (stopRefresh){

How to I perform a delete request one item at a time using Axios?

So, I am building a basic to-do list app using a to-do list api and I am having trouble figuring out how to delete one to-do at a time when the user clicks a delete button. I am using the id# that gets created for a new todo that is made.
I thought the code I currently have would work, but nothing happens when I click the delete button.
Any insights into what I am doing wrong?
Here's all my JavaScript, but what I am having trouble with is the last addEventListener at the bottom of the code:
function Todo(title, description, price){
this.title = title;
this.description = description;
this.price = price;
}
document.todo.addEventListener("submit", function(e){
e.preventDefault();
var titleForm = document.todo.title.value;
var descriptionForm = document.todo.description.value;
var priceForm = document.todo.price.value;
var newTodo = new Todo(titleForm, descriptionForm, priceForm);
axios.post("https://api.todo.io/name/todo", newTodo).then(function(response){
console.log(response.data);
})
})
axios.get("https://api.todo.io/name/todo").then(function(response){
for(var i = 0; i < response.data.length; i++){
var h1 = document.createElement("h1");
var h3 = document.createElement("h3");
var h3Price = document.createElement("h3");
var div = document.createElement("div");
var delButton = document.createElement("button");
var displaytitle = document.createTextNode(`Title: ${response.data[i].title}`);
var displayDescription = document.createTextNode(`Description: ${response.data[i].description}`);
var displayPrice = document.createTextNode(`Price: ${response.data[i].price}`);
var displayButton = document.createTextNode("Delete");
h1.appendChild(displaytitle);
h3.appendChild(displayDescription);
h3Price.appendChild(displayPrice);
delButton.appendChild(displayButton);
div.appendChild(h1);
div.appendChild(h3);
div.appendChild(h3Price);
div.appendChild(delButton);
document.body.appendChild(div);
delButton.addEventListener("submit", function(e){
e.preventDefault();
axios.delete(`https://api.todo.io/name/todo/${response.data[i]._id}`).then(function(response){
console.log("Todo Deleted!");
})
})
}
console.log(response.data);
});
From the docs for the 'submit' event:
Note that submit is fired only on the form element, not the button or submit input. (Forms are submitted, not buttons.)
As for your scoping problem, if you extract the body of your for loop as a function:
function addTodo({ _id, description, price, title }) {
const h1 = document.createElement("h1");
const displaytitle = document.createTextNode(`Title: ${title}`);
h1.appendChild(displaytitle);
const h3 = document.createElement("h3");
const displayDescription = document.createTextNode(`Description: ${description}`);
h3.appendChild(displayDescription);
const h3Price = document.createElement("h3");
const displayPrice = document.createTextNode(`Price: ${price}`);
h3Price.appendChild(displayPrice);
const delButton = document.createElement("button");
const displayButton = document.createTextNode("Delete");
delButton.appendChild(displayButton);
delButton.addEventListener("click", function(e) {
e.preventDefault();
axios
.delete(`https://api.todo.io/name/todo/${_id}`)
.then(function(response) {
console.log("Todo Deleted!");
});
});
const div = document.createElement("div");
div.appendChild(h1);
div.appendChild(h3);
div.appendChild(h3Price);
div.appendChild(delButton);
document.body.appendChild(div);
}
axios.get("https://api.todo.io/name/todo").then(function(response) {
for (var i = 0; i < response.data.length; i++) {
addTodo(response.data[i]);
}
console.log(response.data);
});

Change the Text of a jsPlumb dropped element

I have created an application where elements from the toolbox can be dragged and dropped onto a canvas and their properties can be set as soon as they are dropped. But, I have an instance where when the "stream ui-draggable" element is dropped on the canvas I disable the canvas and the toolbox and display a properties panel where the user can select a predefined stream for the newly dropped element and also give it another name under the "as : " text field. This name should then replace the currently displayed- disabled name "Element" with the name provided bu the user. Is there a way that I can replace this text in the dropped element.
js function:
drop: function (e, ui) {
var dropElem = ui.draggable.attr('class');
droppedElement = ui.helper.clone();
ui.helper.remove();
$(droppedElement).removeAttr("class");
jsPlumb.repaint(ui.helper);
if(dropElem=="stream ui-draggable")
{
var newAgent = $('<div>').attr('id', i).addClass('streamdrop');
//alert("newAgent ID: "+newAgent.attr('id'));
clickedId = newAgent.attr("id");
alert("clicked ID: "+i);
createStreamForm();
$("#container").addClass("disabledbutton");
$("#toolbox").addClass("disabledbutton");
$(droppedElement).draggable({containment: "container"});
var prop = $('<a class="streamproperty" onclick="doclick(this)"><b><img src="../Images/settings.png"></b></a> ').attr('id', (i));
var finalElement= newAgent.text("Element").append('<a class="boxclose" id="boxclose"><b><img src="../Images/Cancel.png"></b></a> ').append(prop);
//Increment the Element sequence number
i++; r++; q++;
var l = ($(finalElement).attr('id'));
alert("Final elm id: "+finalElement.attr('id'));
var connection = $('<div>').attr('id', l + '-' + q).addClass('connection');
finalElement.css({
'top': e.pageY,
'left': e.pageX
});
finalElement.append(connection);
$('#container').append(finalElement);
jsPlumb.draggable(finalElement, {
containment: 'parent'
});
jsPlumb.makeTarget(connection, {
anchor: 'Continuous'
});
jsPlumb.makeSource(connection, {
anchor: 'Continuous'
});
}

storeImportStreamInfo() Function:
var clickcount=1;
function storeImportStreamInfo()
{
var choice=document.getElementById("streamSelect");
var selectedStream = choice.options[choice.selectedIndex].text;
var asName= document.getElementById("istreamName").value;
var StreamElementID = clickcount;
clickcount++;
createdImportStreamArray[clickedId][0]=StreamElementID;
createdImportStreamArray[clickedId][1]=selectedStream;
createdImportStreamArray[clickedId][2]=asName;
y++;
}
Solved it by passing the newly dropped jsPlumb object to the storeImportStreamInfo() as parameters and set the text within the method. Also this parameter needs to be carried through all the functions through which it progresses before achieving the storeImportStreamInfo() method.
Eg:
function createStreamForm(newAgent,i)
within this function->
importbtn.onclick = function() {
storeImportStreamInfo(newAgent,i);
}
and so on. In the storeImportStreamInfo() function, I've added the lines that append the icons and the text to the dropped Element.
var prop = $('<a class="streamproperty" onclick="doclick(this)"><b><img src="../Images/settings.png"></b></a> ').attr('id', (i));
newAgent.text(asName).append('<a class="boxclose" id="boxclose"><b><img src="../Images/Cancel.png"></b></a> ').append(prop);

Create JQuery Mobile button using JavaScript

I need help to create jQuery mobile button using JavaScript, I am using the code below, it creates a button but it is not recognizing the jQuery mobile style.
thanks for your help :)
function SubmitForm() {
var list = document.getElementById("forMore"); // Get the <ul> element with id="forMore"
if (list.hasChildNodes()) { // It has at least one
list.removeChild(list.childNodes[0]);
}
var e = document.getElementById("services");
var strUser = e.options[e.selectedIndex].value;
var id = e.options[e.selectedIndex].id;
document.getElementById("desc").innerHTML = strUser;
document.getElementById("fields").style.visibility = "visible";
var td = document.getElementById('forMore');
var btn = document.createElement('input');
btn.setAttribute("data-role", "button");
btn.setAttribute("data-theme", "b");
btn.setAttribute("class", "ui-input-btn");
btn.style.cssFloat = "left";
btn.style.fontSize = "18px";
btn.style.fontFamily = "myAccountFont";
btn.style.color = "green";
btn.onclick = function () {
location.href = "/Pin/SendVas?id=" + id;
};
btn.value = "تفعيل";
td.appendChild(btn);
}
hope this will help:
var a = document.createElement("A");
a.appendChild(document.createTextNode("Name"));
a.setAttribute("data-role","button");
a.setAttribute("data-inline","true");
a.setAttribute("data-corner","false");
$(td).append(a).trigger('create');
//Or user parent container:
$("#container").trigger('create');

removing child from a child

I am having trouble removing the child of a child of an object created using JS.
Basically once I create a comment object I appendChild(replyBox) to it. Inside the replyBox there is a cancel button which is supposed to completely delete the replyBox.
Here is the code :
function Comment(message){
var self = this;
var message = message;
var comment = document.createElement("li");
comment.id = "comment";
comment.style = "display: none;";
comment.textContent = message;
createButtons(comment);
var parent = document.getElementById("wall");
parent.appendChild(comment);
return comment;
}
function deleteComment(comment){
var parent = document.getElementById("wall");
parent.removeChild(comment);
}
function newReply(comment){
var buttons = comment.getElementsByTagName("input");
buttons.item(0).disabled="disabled";
var replyBox = document.createElement("div");
replyBox.id="replyBox";
var replyTxt = document.createElement("input");
replyTxt.type="text";
replyTxt.value="Write a reply";
replyTxt.onfocus = "if(this.value==this.defaultValue) this.value='';" ;
replyTxt.onblur="if(this.value=='') this.value=this.defaultValue;";
replyBox.appendChild(replyTxt);
createButtons(replyBox);
comment.appendChild(replyBox);
}
function createButtons(parent){
var button = document.createElement("input");
button.type = "submit";
if(parent.id=="comment"){
var reply = button.cloneNode();
reply.value = "reply";
reply.addEventListener("click", function(){newReply(parent)},false);
parent.appendChild(reply);
var deleteBtn = button.cloneNode();
deleteBtn.value = "delete";
deleteBtn.addEventListener("click", function(){deleteComment(parent)},false);
parent.appendChild(deleteBtn);
}
else{
var submitBtn = button.cloneNode();
submitBtn.value = "submit";
//reply.addEventListener("click", function(){newReply(parent)},false);
parent.appendChild(submitBtn);
var cancel = button.cloneNode();
cancel.value = "cancel";
cancel.addEventListener("click", function(){cancel(parent)},false);
parent.appendChild(cancel);
}
}
function cancel(replyBox){
replyBox.parentNode.removeChild(replyBox);
}
cancel.addEventListener("click", function(){cancel(parent)},false);
Which cancel is which? You have an object called cancel as well as a function with the same name. Try renaming one.
I see a problem here:
comment.id = "comment";
If you're setting all IDs of the comment elements to comment, the DOM may be getting confused.
