Brief synopsis of what I am doing: As of now I am trying to build a 6 x 6 grid and get some sign of life when I click on any of the grid boxes.
The result I want for now, is by clicking in any of the boxes I get a console message saying a piece was picked.
My main goal is to be able to differentiate between which box I picked, but first I need to figure it out generally.
HTML:
<div class="container">
<div class="row">
<div class="btn btn-lg btn-success col-lg-offset-4 col-md-4" id="makeBoard">Generate Board</div>
</div>
<div id="spacer"></div>
<div class="row">
<div class="col-md-12" id="newBoard"></div>
</div>
</div>
JQuery:
$(function(){
$('#makeBoard').click(function() {
var boardSize = 6;
makeBoard(boardSize);
});
function makeBoard(boardSize){
for(i = 0; i < boardSize; i++){
$('#newBoard').append("<div class='row' id='row"+i+"'>");
var row = "#row"+i;
for(j = 0; j < boardSize; j++){
var content = "<div class='col-md-2 boardPiece' id='"+i+"_"+j+"'></div>";
$(row).append(content);
}
$('#newBoard').append("</div>");
}
}
$('div.boardPiece').click(function() {
console.log("You clicked a piece!");
});
});
I double checked the html output by inspecting the element and indeed all the squares have the class 'boardPiece' but whenever I click on anywhere in the grid nothing gets logged in the console.
However, I have tried to console log the id 'newBoard' by clicking anywhere in the box and that worked. I'm assuming it has something to do with the boardPiece not being hardcoded in using HTML like newBoard is?
I'm using JS/JQuery so I can eventually change the board size from a form.
Thank you in advance.
Edit (Answer Below)
//Changed from this
$('div.boardPiece').click(function() {
console.log("You clicked a piece!");
});
//To this
$('.row').on("click", "div.boardPiece", function() {
console.log("You clicked a piece!");
});

I am trying to append a box to a list. This box should have a heading which identifies it, but I am having trouble figuring out how to increment each heading by 1.
Currently, the boxes are being generated by this code when a button is clicked.
function createBoxYes(i) {
var box = '<div class="panel-heading">Question 1</div>';
$("#yesColumn").append(box);
}
However, I am trying to increment the Question number based on the input, i. It should equal i + 1. My first thought was to put an id on the div, but if I used findElementById("question"), then it would select all of the boxes, and I want to simply have each box generated to remain unchanged.
Thanks for the help!
This may help you.
function createBoxYes(i) {
var box = '<div class="panel-heading">Question' + (i + 1) +'</div>';
$("#yesColumn").append(box);
}
Just put i+1 in there.
I hope this ll helps you:
var questions = 1;
function createBoxYes() {
var box = '<div class="panel-heading">Question ' + ++questions + '</div>';
$("#yesColumn").append(box);
}
$('#addBox').bind('click', createBoxYes);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<link href="http://getbootstrap.com/dist/css/bootstrap.min.css" rel="stylesheet" />
<div id="yesColumn" class="panel panel-default">
<div class="panel-heading">Question 1</div>
</div>
<button id="addBox" class="btn btn-info">Add</button>
My HTML
<div class="chapter">text text text </div>
<div class="chapter">text text text </div>
<button id="button">button</button>
My js
var button = document.querySelector('#button');
var chapter = document.querySelectorAll('.chapter');
for(var i = 0; i < chapter.length; i++){
button.addEventListener('click', function(){
for(var i = 0; i < chapter.length; i++) {
chapter[i].classList.add('active');
}
});
}
This adds the class of "active" on clicking the button.
But toggle doesn't work. Instead of
chapter[i].classList.add('active');
When I do,
chapter[i].classList.toggle('active');
the class of "active" does not toggle. console shows no error.
So I tried to check the class of "active" first & remove the class if the class exists. I know I was trying to reinvent the toggle function; as stated above, toggle wasn't working so I tried it anyway.
if (chapter[i].contains('active')){
chapter[i].classList.remove('active');
And I got a slew of error messages. This is as far as I got. I somehow felt that this wasn't going to work but just tried it anyway.
I am stumped.
Can anyone point out why classList.toggle isn't working in my code & how this can be fixed?
Thanks.
You have one too many loop. Remove the outer one:
var button = document.querySelector('#button');
var chapter = document.querySelectorAll('.chapter');
button.addEventListener('click', function(){
for(var i = 0; i < chapter.length; i++) {
chapter[i].classList.toggle('active');
}
});
.active{
color: red;
}
<div class="chapter">text text text </div>
<div class="chapter">text text text </div>
<div class="chapter">text text text </div>
<div class="chapter">text text text </div>
<button id="button">button</button>
var button = document.querySelector('#button');
var chapters = document.querySelectorAll('.chapter');
button.addEventListener('click', function(){
for(var index = 0; index < chapters.length; index++) {
if(chapters[index].classList.contains('active')){
chapters[index].classList.remove('active');
}else{
chapters[index].classList.add('active');
}
}
});
.active {
color: red;
}
<div class="chapter">text text text </div>
<div class="chapter">text text text </div>
<button id="button">Toggle Color</button>
<script>
$(document).foundation(
var count = 1
$("button.test").click(function(){
if ($("p.change-me").text() === "OFF") {
$("p.change-me").text("ON")
count = count + 1
}
else if ($("p.change-me").text() === "ON") {
$("p.change-me").text("OFF")
count = count + 1
}
$("p.counter").text(count)
})
)
</script>
Very simply, I want to show the count as I am pressing this On and Off button. However, when I add the "var count = 1", my button no longer works. When I get rid of that line, the button will turn the text in the tag from ON to OFF and from OFF to ON.
How come? As you can probably tell, I am teaching myself JQuery.
Thanks!
HTML as requested:
<div class="row">
<div class="small-6 columns text-center">
<button class="button radius test">CLICK THIS</button>
</div>
<div class="small-6 columns text-center">
<p class="change-me">OFF</p>
</div>
</div>
<div class="row">
<div class="small-12 columns text-center">
<p>Here we will print how much fun you are having:</p>
<p class="counter">0</p>
</div>
</div>
Take your code out of the foundation() call. Also try to remember using semicolons.
$(document).foundation();
var count = 1;
$("button.test").click(function(){
if ($("p.change-me").text() === "OFF") {
$("p.change-me").text("ON");
count = count + 1;
}
else if ($("p.change-me").text() === "ON") {
$("p.change-me").text("OFF");
count = count + 1;
}
$("p.counter").text(count);
})
#Romain's answer is correct, but just to add to that... foundation is a method-call, and you were trying to put javascript code in the section where you normally put parameters (ie inside the ()). javascript code normally has to go inside of a function's body, not in the section where you type the parameters.
Oke, so I am trying to create an interactive menu.
Now I am really struggling to make the JavaScript access the child nodes of a div and change a specific css element.
The html code goes as follow:
<div id="navbar">
Control panel
<div class="button" onclick="openMe(self);">
Users
<div class="sub-button">
Profile
</div>
<div class="sub-button">
Ban
</div>
</div>
<div class="button">
Roles
<div class="sub-button">
Profile
</div>
<div class="sub-button">
Ban
</div>
</div>
</div>
And the JavaScript is :
function openMe(a)
{
child = a.document.getElementsByClassName('sub-button');
console.log("a is "+a);
console.log("child is "+$(child).get());
console.log(self);
for (i = 0; i < child.length; i++){
//
console.log("Key "+i+" is "+child[i]);
console.log("Display for "+i+" is "+child[i].style.display);
if (child[i].style.display == "" || child[i].style.display == "none"){
child[i].style.display = "block";
} else {
child[i].style.display = "none";
}
}
}
In the css sub-button is hidden.
Now I have been trying to google, but I haven't found anything even close.
How can I make it that if I press button, the sub-buttons within button change css elements?

Angels

The error is in the first line. When you would open the error console, a error message will occur.
Change the line a.document.getElementsByClassName('sub-button'); to a.getElementsByClassName('sub-button');.
The second error is change onclick="openMe(self); to onclick="openMe(this);.
First time trying javascript and i cant find a solution about this.
I need a open/close div button.
if div1 is not visible and i press button 1
set it visible
set all other not visible
elseif div1 is visible and i press button 1
set it not visible
this is my code so far...
<script type="text/javascript">
function toggle_visibility(id)
{
if (document.getElementById(id).style.display=='block')
{
document.getElementById(id).style.display='none';
}
else
{
document.getElementById(id).style.display='block';
for (i=0; i<5; i++)
{
document.getElementById(i).style.display='none';
}
}
}
</script>
<button onclick="toggle_visibility(1);">
1
</button>
...
<button onclick="toggle_visibility(5);">
5
</button>
i forgot this ->
<div id="1" style="display:none">
1
</div>
...
<div id="5" style="display:none">
5
</div>
You have no element with a id. And a id must not begin with an number (in (X)HTML, but not HTML5)! If you just want to show one element try my showOnly function.
<script type="text/javascript">
function toggle_visibility(id)
{
var i; // omiting this causes a global variable
if (document.getElementById("a"+id).style.display=='block')
{
document.getElementById("a"+id).style.display='none';
}
else
{
document.getElementById("a"+id).style.display='block';
for (i=1; i<=5; i++)
{
document.getElementById("a"+i).style.display='none';
}
}
}
function showOnly(id) {
for(var i=1; i<=5; i++) {
document.getElementById("a"+i).style.display='none';
}
document.getElementById("a"+id).style.display='block';
}
</script>
<div id="a1" onclick="toggle_visibility(1);">1</div>
<!-- ... -->
<div id="a5" onclick="toggle_visibility(5);">5</div>
See also this fiddle.
You're missing the ID attribute from your div's.
<div id="yourId">
Ideally the ID shouldn't start with a number.
In addition you can use the browser console window to help identify such problems.
