How to properly remove the contents inside of a modal

How to properly remove the contents inside of a modal - javascript

The heights of each building from West (left) to East (right) is given in an integer array. You have to tell which buildings will be able to see the sunset. I've written a program that will be able to tell which buildings can view the sun from left to right. The problem I'm having is currently with the modal. I'm trying to clear the information that is inside the modal use clearContents(). At first, I was using clear() till i noticed that clear() is a global method. I then tried using document.getElementById("results").innerHTML = " ";.
the entire website is provided but the code snippet is below.
https://zacharyhadjahsunsethills.netlify.app/
let sunsetOrder = ["Building 1 will always view the sunset!"];
function BeginFunction(){
//wire up all the data to the building variables
let building1 = parseInt( document.getElementById("input1").value )
let building2 = parseInt( document.getElementById("input2").value )
let building3 = parseInt( document.getElementById("input3").value )
let building4 = parseInt( document.getElementById("input4").value )
let building5 = parseInt( document.getElementById("input5").value )
//User Input validation
if(building1 == null || building2 == null || building3 == null || building4 == null ||
building5 == null){
document.getElementById("results").innerHTML = `You must input numbers for all buildings`
//clear data
document.getElementById("results").innerHTML = ``
}else{
//Put all the buildings into an array
let buildingsArray = [building1, building2, building3, building4, building5]
//You will need to use nested for loops. Nested for loops are how you can properly
//compare elements inside of an array with eachother.
//Loop starts at one because it will be the loop that is compared to all the
//previous buildings that are infront of it
for (let currentBuilding = 1; currentBuilding < buildingsArray.length; currentBuilding++) {
//will be kept false UNTIL you find the tallest building
//once tallest building is found, it will be switched to true
let tallest = false;
//this loop starts at one because it will need to stay before the position of the
//current building. It needs to stay before current building to properly compare
//which building is taller. That is why the middle condition is
// previousBuilding < currentBuilding
for (let previousBuilding = 0; previousBuilding < currentBuilding; previousBuilding++) {
//if any of the previous building are taller than the building that is currently being compared with,
//then change the bool to true
if(buildingsArray[previousBuilding] >= buildingsArray[currentBuilding]){
tallest = true;
break;
}else{
continue;
}
}
if(tallest == false){
sunsetOrder.push("Building #" +(currentBuilding + 1)+ " can view the sunset")
}
else{
sunsetOrder.push("Building #" +(currentBuilding + 1)+ " can't view the sunset")
}
let results = sunsetOrder.join("<br>")
document.getElementById("results").innerHTML = `${results}`
}
}
}
function clearContents(){
document.getElementById("results").innerHTML ="";

If you inspect the content of the web with the devs tools you can see that your function clearContents() is working correctly.
The problem here is that you ain't clearing your sunsetOrder array, so every time that you do click on the submit button you are pushing new elements to it and showing all the array in the modal.
To solve this you can add the following code to your clearContents function:
function clearContents() {
document.getElementById("results").innerHTML ="";
sunsetOrder = [];
}

Why does my delete button does not delete the card

I want to delete the card when we click on the delete button after adding a TODO note
I have created a website which uses localstorage to store notes and display when clicking the create TODO button and it all works but when I click the delete button after the note is created (You have to create a TODO first) it does not delete the div itself
I want to delete the card when we click on the delete button

</html>

The error is thrown on this line onclick='${key}.innerHTML=""'. You will want to first remove the item from local storage e.g: localStorage.removeItem('${key}') and then remove the html. Theres many way of achieveing this but this.parentElement.parentElement.remove() should be sufficient
The complete button should look something like <button type="button" id="note" onclick="localStorage.removeItem('${key}'); this.parentElement.parentElement.remove()" class="btn btn-danger '${key}'">Delete</button>
Heres a working example:
https://jsfiddle.net/qt83bshd/

Well, i post you a simple solution for your problem.
Instead of use innerhtml to introuce your todos, yo can create the elements.

how to clear search result while click in search button

I made a song and a lyric searching page. The first time search is working well but while I click in the search button the previous result remains and also search results also shown on the page.
Now I want to disappear the result while searching for another song or lyric.
And also I want to make the search the result same style but I don't get results as I wanted.
const text = document.getElementById('text');
const search = document.getElementById('search');
const result = document.getElementById('result');
// api url
const api= 'https://api.lyrics.ovh';
// song lyrics
function getLyrics (artist, title) {
let url = `${api}/v1/${artist}/${title}`
fetch(url)
.then(res => res.json())
.then(singerLyrics => {
const lyrics = singerLyrics.lyrics;
const getLyric = document.getElementById('getLyric');
getLyric.innerHTML = `<h2 class="text-success mb-4">${artist} - ${title}</h2>
<pre class="lyric text-white">${lyrics}</pre>`;
});
result.innerHTML= '';
}
// search by song or artist
function searchSongs(term){
fetch(`${api}/suggest/${term}`)
.then(res => res.json())
.then (showData);
};
// search result
function showData (data) {
result.innerHTML = `<div class="single-result row align-items-center my-3 p-3">
<div class="col-md-9"> ${data.data.map(song => `<h3 class="lyrics-name">${song.title}</h3>

`;
};

try to use autocomplete="off" like
<input type="text" name="foo" autocomplete="off" />

Every time, search is clicked, the lyrics container should be emtpied:
document.querySelector("#getLyric").childNodes.forEach(el => el.remove())
to fix the issue, add this to your script:
document.querySelector("#search").addEventListener('click', function () {
document.querySelector("#getLyric").innerHTML = '';
})

Bootstrap modal window won't open because of interference with other elements

I can't seem to figure out why bootstrap's modal window isn't popping up.
I've looking into other similar questions and I still can't get it to work.
I've tried the process of elimination and try to eliminate all my scripts (except the bootstrap script) and it still won't open. Same with my CSS files. I also had inputted manual code for a modal window (before I incorporated bootstrap) so I was worried that the id="modal" from other modals would interfere. I deleted those too and nothing worked.
Here is my codepen, I've commented the sections the modal window code starts: https://codepen.io/eylenkim/pen/KKwMPLm

There are 2 separate issues that are preventing the modal from showing up.
1) The first issue is with your code
The bootstrap library you use returns 404.
How to check if it's happening for you?
Open your browser's inspector, and press CTRL+SHIFT+I
You will see:
Failed to load resource: the server responded with a status of 404 () eylenkim/fullpage/bootstrap-4.3.1-dist/css/bootstrap.css
In fact, this happens for a lot of your relative URLs.
Solution
Replace links to Bootstrap libraries with working ones, eg. from https://getbootstrap.com/
The ones I used in my testing of your code:
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/css/bootstrap.min.css" integrity="sha384-Vkoo8x4CGsO3+Hhxv8T/Q5PaXtkKtu6ug5TOeNV6gBiFeWPGFN9MuhOf23Q9Ifjh" crossorigin="anonymous">
<script src="https://code.jquery.com/jquery-3.4.1.slim.min.js" integrity="sha384-J6qa4849blE2+poT4WnyKhv5vZF5SrPo0iEjwBvKU7imGFAV0wwj1yYfoRSJoZ+n" crossorigin="anonymous"></script>
<script src="https://cdn.jsdelivr.net/npm/popper.js#1.16.0/dist/umd/popper.min.js" integrity="sha384-Q6E9RHvbIyZFJoft+2mJbHaEWldlvI9IOYy5n3zV9zzTtmI3UksdQRVvoxMfooAo" crossorigin="anonymous"></script>
<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/js/bootstrap.min.js" integrity="sha384-wfSDF2E50Y2D1uUdj0O3uMBJnjuUD4Ih7YwaYd1iqfktj0Uod8GCExl3Og8ifwB6" crossorigin="anonymous"></script>
See gist for minimum code sample for a modal here: https://codepen.io/edwin-chua/pen/rNaLOEg
Once you fix the link problem, you will run into the second issue.
2) The second issue is with your stylesheet
Once you fixed your code as I suggested, you get a dark overlay with no modal.
Removing the reference to https://eylenkim.github.io/ArtByEylen/StyleSheet.css allows the modal to show up, so something in here is interfering with the modal's css.
Here is a working pen: https://codepen.io/edwin-chua/pen/QWwEyyZ
Separate Problem
You seem to have imported some libraries twice, once in the Codepen UI, and once in the HTML file. This will cause you debugging headaches. Make sure you only import them once. Since you are building an entire webpage, I suggest putting all of it in the HTML file.
also see JS tab
And
Further Comments
This section of code seems to be for closing the modal? If so, it probably isn't required, as Bootstrap automatically binds the click events.
<!--Modal - Dialog Boxes -->
<script type="text/javascript"> const modals = Array.from(document.querySelectorAll('.modal'));
const triggers = Array.from(document.querySelectorAll('.trigger'));
var closeButton = document.querySelector(".close-button");
//if a trigger is clicked then...
for (const trigger of triggers) {
trigger.addEventListener('click', toggleModal);
}
// .. then toggle it's modal
function toggleModal(event) { event.target.closest('.trigger').querySelector('.modal').classList.toggle("show-modal"); }
// check if the clicked element is a modal, or in a modal
function windowOnClick(event) {
if (modals.some((modal) => modal.contains(event.target))) {
toggleModal();
}
}
</script>

How to fix input issue in CodeMirror

I'm trying to get code mirror to read and display the contents of a file into the textarea, but everytime I load a file, it prints the contents as one line, ignoring all line breaks, and if I try to manually enter text into the text field, it automatically tabs every line after the first.
Proper text form file format:
Proper textarea styling:
Unfortunate result of selecting a file (this text format won't function with the compile button):
Full HTML code (with suggested edits; still not working):

Hopefully someone can spot what's being done wrong.

CodeMirror has several Content manipulation methods. You will need to use the setValue method.
doc.setValue(content: string)
Set the editor content.

More specifically, editor.setValue(this.result); is what got it working. Take a look at this JS Bin
In your fileUploadScript.js you must use editor.setValue().
document.getElementById("filebutton").addEventListener('change', function () {
var fr = new FileReader();
fr.onload = function () {
editor.setValue(this.result);
//document.getElementById("textarea").textContent = this.result;
}
fr.readAsText(this.files[0]);
})
You can't force the code into the textarea. It just won' work. You have to use the setValue method as shown above.

How to prevent jquery submit button from refreshing the HTML page?

I have a login page where the user enters his username and password, when he submits this form the data is sent to php file for verifying the password.
For the first time when the user enters data (I entered wrong details) the page shows "Invalid password...please try again".
The second time when the user enters data (again I enter wrong details) the page just reloads. I am not able to understand why this is happening.
For more better understanding I have added a google drive link to a video showing the issue.

The javascript part:
$(document).ready(function () {
$("#admin-signin").submit(function (e) {
e.preventDefault();
let admin_username = $("#admin_username").val();
let admin_password = $("#admin_password").val();
$.ajax({
url: 'php_admin_login.php',
data: {
admin_username: admin_username,
admin_password: admin_password
},
type: "POST",
dataType: "json",
success: function (response) {
if (response === "OK") {
window.open("admin.html", "_self");
}
else {
document.getElementById('admin-signin-card').innerHTML += '<div class="alert alert-danger"><h5>Error occured...Please try again</h5></div>';
console.log("error shown");
}
}
});
});
});
I'm sure there is no problem with the php code so I'm not pasting here just to make the question more clearer.
If you need the whole code of the project you can get it here:Github link to the project

else {
document.getElementById('admin-signin-card').innerHTML += '<div class="alert …>';
Adding to an element’s .innerHTML replaces the whole content of the element; even the stuff that was already there will first be removed, and then re-created.
So your form itself is replaced with a new form, and therefor you completely lose your submit event handler you had attached to it as well.
Your attempts at preventing the default event action fail, because you handler function simply doesn’t get called any more at all, and just a normal form submit is performed now, which of course reloads the page.
You need to either add your event handler again after you replaced the parent container’s innerHTML - or use event delegation to begin with.

Try to use this. Hope it will help
$("form").submit(function(e){
e.preventDefault();
});
Kindly let me know if it does not work.

Try return false at the end of your $("#admin-signin").submit function instead of the preventDefault()

This is happening due to how you handle errors. By using document.getElementById('admin-signin-card').innerHTML += ... you are effectively reloading your form meaning that you lose the event listener. You can either adjust how you display the error or adjust the event listener.
I would recommend changing how you display the error.
I have removed the request in the example below but it's the same idea:
$(document).ready(function () {
$("#admin-signin").submit(function (e) {
e.preventDefault();
let admin_username = $("#admin_username").val();
let admin_password = $("#admin_password").val();
let response = "no";
if (response === "OK") {
window.open("admin.html", "_self");
} else {
document.getElementById('admin-signin-card-error').innerHTML ='<div class="alert alert-danger"><h5>Error occured...Please try again</h5></div>';
console.log("error shown");
}
});
});

like #CBroe mentioned, the problem is caused by innerHTML.
i moved the content of innerHTML to the form, and give it display none, when there an error i show the error with .show()
i changed the ajax url and data Type for testing purpose.
$(document).ready(function () {
$("#admin-signin").on('submit', function (event) {
event.preventDefault();
let admin_username = $("#admin_username").val();
let admin_password = $("#admin_password").val();
$.ajax({
url: 'https://jsonp.afeld.me/?url=https://jsonview.com/example.json',
type: "POST",
dataType: "jsonp",
data: {
admin_username: admin_username,
admin_password: admin_password
},
success: function (response) {
if (response === "OK") {
window.open("admin.html", "_self");
} else {
$('.alert.alert-danger').show();
console.log("error shown");
}
}
});
});
});
