GIF1(In this GIF my checkboxes are disabled by default and auto check if i click the phase buttons)
GIF2(In this GIF my first checkbox is enabled, and if the first checkbox is clicked the submit button works)
My end goal is to actually have the submit button work if they re automatically checked like in the first GIF.

You need to run the functionality of shadowFunction() in phase1Function(). If the button is disabled the if statement in shadowFunction() never runs.
I think you should call the shadowFunction() at the end of the fifth button, like this:
funct
function phase5Function() {
document.getElementById("c5").checked=true;
alert("You have completed Phase 5!");
shadowFunction();}

I have two files index.html and index.js. When I fill the text fields in the form and click the button, it should redirect to index.js. How do I achieve that?
index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document</title>
</head>
<body>
<h1 id="head">Hello</h1>
<input type="email" id="email"></input>
<br><br>
<input type="password" id="pass"></input>
<br><br>
<button>Click</button>
<script src="index.js"></script>
</body>
</html>
index.js
if (document.getElementById("email").nodeValue==document.getElementById("pass").nodeValue){
alert("You are allowed");
}
EDIT: I can do this simply by creating the function inside the <script> tag itself and then calling the function inside onClick in the <button> tag. But instead, I want the onClick to call my index.js script which will perform the backend stuff
declare this function in index.js
function handleClick() {
if (
document.getElementById('email').nodeValue ===
document.getElementById('pass').nodeValue
) {
alert('You are allowed');
}
}
call it on button click
<button onclick="handleClick()">Click</button>
you should link the html file to the javascript file using
<script type="text/javascript" src="(your file location)"></script>
then add event listeners to listen to the button click using
document.addEventListener('DOMContentLoaded', function () {
document.getElementById("button-id").addEventListener('click', yourFunction)
});
function yourFunction(){
//your code here
}
also add an id to the button so you can add the event listener to it
<button id="button-id">Click</button>
You need to use EventListener to bind button click event to a function.
document.getElementsByTagName('button')[0].addEventListener('click',function(){
if (document.getElementById("email").value==document.getElementById("pass").value){
alert("You are allowed");
}
});

<input type="email" id="email"></input>
<br><br>
<input type="password" id="pass"></input>
<br><br>
<button>Click</button>
</body>
</html>
you should add the js file in your index.html
<script type="text/javascript" src="index.js"></script>
then you should add onclick event on your button
<button onclick="myFunction()">Click</button>
then in index.js you should add the function
function myFunction(){
//your logic goes here
}
Always call your script inside js only. It is bad practice to call scripts in the html structure. I gave you an example of calling script logic and accessing a component using querySelector().
var form_button = document.querySelector('.thisisbutton');
var email_input = document.querySelector("#email");
var pass_input = document.querySelector("#pass");
form_button.onclick = function() {
if (email_input.value == pass_input.value){
alert("You are allowed");
}
}
<body>
<h1 id="head">Hello</h1>
<input type="email" id="email">
<br><br>
<input type="password" id="pass">
<br><br>
<button class="thisisbutton">Click</button>
</body>
I'm learning Javascript and now I'm making to-do list.I've finished the basic one but I want to add the delete button which delete all the checked lists to my to-do list.
I've tried some ways that I came up with and they all failed and I cannot find the answer by googling.
How can I do this ? If there is someone who know, please teach me . I'd appreciated if you could show me how.
this is my code ↓ the error happened saying cannot read property 'parentElement' of null at Object.deleteAll
deleteAll: function() {
let taskListItem, checkBox, checkBoxParent;
for (i=0; i<this.taskListChildren.length; i++){
taskListItem = this.taskListChildren[i];
checkBox = taskListItem.querySelector('input[type = "checkbox"]:checked');
checkBoxParent = checkBox.parentElement;
checkBoxParent.remove();
}
document.getElementById('deleteChecked').addEventListener('click', () => {
tasker.deleteAll();
});
🙏

You can use the jQuery library and solve it as follows.
Step 1) Define in your html button element:
<button id="button" onclick="reset()"> RESET </button>
Step 2) define the 'reset ()' function, like this
function reset()
{
$("input:chceckbox").removeAttr("chcecked");
}
Good luck!!
I am trying to run two JQuery events at the same time. When there is only one of them active they both do work but if they are active together, only one event is fired.
One event is listening for when the input loses the focus, the other one is for getting the text of a live search result. My thought was to hide the result div once the input loses the focus (user clicks on something different). The other event is for getting the result as already mentioned when the user clicks on something in the result div and hide it afterwards.
$(document).on("focusin", 'input.mdb-min-input', function(event) {
$("div.result").html('<p class="live-results"> Test1 </p><p class="live-results"> Test2 </p>');
});
$(document).on("click", '.live-results', function(event) {
console.log("click!");
$(this).parents(".search-box").find('input[type="text"]').val($(this).text());
});
$(document).on("blur", 'input.mdb-min-input', function(event) {
console.log("blur!!");
$(this).siblings(".result").empty();
});

<p class="live-results"> Test2 </p>
</div>
</div>
<div class="spacer"> </div>
<div class="search-box">

</html>
. The problem is that only the blur event is fired.
I have already tried to change the order of both events but this doesn't help.
I will provide you the code.
I want to get an answer from the php file if I click on one of the radio buttons, but if I use the radio button, the alert appers in an endless loop. Why? And how do I get the alert only once?
I try it with only a „normal“ button, then it works:
If I click on the button, the ajax responds the values in the alert once.
Thank you

As the alert appears, the radio button will lose focus. As you close the alert, the focus will return which triggers the alert which causes the radio button to lose focus but when you close that alert ...
Use console.log instead
Try this, your code is right just need one change...
write return false; immediately after alert.
means...function(data) { alert(data); return false; }
I wanted to modify something in my code and don't really know how to make this work... my code is kinda huge so I am going to explain what I want with an exemple :
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<link rel="stylesheet" href="stylesheets/application.css">
</head>
<body>
<label>Enter value : </label><input type="text" maxlength="512" id="reg_expr"/>
<div id="button">OK</div>
<div id="nfa"></div>
<script src="script1.js"></script>
<script src="script2.js"></script>
<script src="script3.js"></script>
</body>
</html>
So this is my HTML code, so what I want to do is NOT execute these 3 scripts until the user enters a value in the text input and clicks on OK. That value will be used in the js files, so i have to get the value after I click OK.
Can someone explain how this has to work ?
EDIT : problem was with jQuery that was not executing on Electron, solution : http://ourcodeworld.com/articles/read/202/how-to-include-and-use-jquery-in-electron-framework
For starters I would suggest changing; <div id="button">OK</div> to <button id="button">OK</button>.
I would then suggest to put each of those scripts into functions instead, then you can use the 'onClick' event from the button attribute as follows;
<button id="button" onClick="s1Func();s2Func();s3Func();">OK</button>
A better way would be to have one function call 'init' or something appropriate that then calls the 3 scripts/functions and have your buttons onClick even call that one initialization function.
JSFiddle Example:
https://jsfiddle.net/JokerDan/h7htk9Lp/
I would recommend you to load the scripts dynamically after you click on the button. This can be done via jQuery: https://api.jquery.com/jquery.getscript/

<label>Enter value : </label><input type="text" maxlength="512" id="reg_expr"/>
<div id="button" onclick="loadScripts();">OK</div>
<div id="nfa"></div>
<script>
function loadScripts() {
// Is the input empty?
var value = $("#reg_expr").val();
if (value.length != 0) {
// Loads and executes the scripts
console.log(value); // Displays the value of the input field
$.getScript("script1.js");
$.getScript("script2.js");
$.getScript("script3.js");
}
}
</script>
</body>
</html>
You can use a button tag instead of input tag. I suggest you to use onClick event like this:
<button type="button" onclick="yourFunction()">Click me</button>
When the users click the button yourFunction() is call.
The result is this:
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<link rel="stylesheet" href="stylesheets/application.css">
<script src="script1.js"></script>
<script src="script2.js"></script>
<script src="script3.js"></script>
</head>
<body>
<label>Enter value : </label><input type="text" maxlength="512" id="reg_expr"/>
<button type="button" onclick="yourFunction()">Click me</button>
</body>
</html>
