I was actually using a script which allowed me to Show a div onclick and hide others but now I need to do the same with "class" instead of "id".
My current script:
function layout(divName){
var hiddenVal = document.getElementById("tempDivName");
if(hiddenVal.Value != undefined){
var oldDiv = document.getElementById(hiddenVal.Value);
oldDiv.style.display = 'none';
}
var tempDiv = document.getElementById(divName);
tempDiv.style.display = 'block';
hiddenVal.Value = document.getElementById(divName).getAttribute("class");}
What I tried using getElementsByClassName :
function layoutNEW(divName){
var hiddenVal = document.getElementById("tempDivName");
if(hiddenVal.Value != undefined){
var oldDiv = document.getElementById(hiddenVal.Value);
oldDiv.style.display = 'none';
}
var tempDiv = document.getElementsByClassName(divName);
for ( var i=0, len=tempDiv.length; i<len; ++i ){
tempDiv[i].style.display = 'block';
}
hiddenVal.Value = document.getElementById(divName).getAttribute("id");}
Any ideas ?
EDIT : A working example of my current script with "id" : JSFiddle
EDIT 2: It works great, but when the div (class) is cloned, only one of them is showing the div. Do you have an idea about this ? Where is a JSFiddle demonstrating the situation: JSFiddle
I think this is what you'd need. The idea is that you can use a data property on your <a> tags that will tell your click handler which classname to look for when showing an element. From there, you just hide the others. Here's a working demo:
var toggleControls = document.querySelectorAll("[data-trigger]");
var contentDivs = document.querySelectorAll(".toggle");
for (var i = 0; i < toggleControls.length; i++) {
toggleControls[i].addEventListener("click", function(event) {
var trigger = event.target;
var selector = "." + trigger.getAttribute("data-trigger");
var divToShow = document.querySelector(selector);
for (j = 0; j < contentDivs.length; j++) {
contentDivs[j].style.display = "none";
}
divToShow.style.display = "block";
});
}
.toggle {
height: 100px;
width: 100px;
display: none;
}
.div1 {
background-color: red;
}
.div2 {
background-color: blue;
}
.div3 {
background-color: purple;
}
.div4 {
background-color: green;
}
Show Div1
<br/>
Show Div2
<br/>
Show Div3
<br/>
Show Div4
<div class="toggle-container">
<div class="toggle div1"></div>
<div class="toggle div2"></div>
<div class="toggle div3"></div>
<div class="toggle div4"></div>
</div>
EDIT - As per updated question
In order to get this to work with dynamically created elements, you will have to put the var contentDivs = ... inside of the click handler, so you get a live version of that array. Also, you will need to change .querySelector to .querySelectorAll as the former only grabs the first matching element, not all as the latter does.
Here's what the code would look like: (note - I also moved the click handler into an outside function so it was not being recreated for every iteration of the loop, as is good practice)
function clickHandler(event) {
var contentDivs = document.getElementsByClassName("toggle"); // get live set of contentDivs in case any were added dynamically
var trigger = event.target;
var selector = "." + trigger.getAttribute("data-trigger");
var divsToShow = document.querySelectorAll(selector); // grab all matching divs
for (var i = 0; i < contentDivs.length; i++) {
contentDivs[i].style.display = "none";
}
for (var j = 0; j < divsToShow.length; j++) {
divsToShow[j].style.display = "block";
}
}
var toggleControls = document.querySelectorAll("[data-trigger]");
for (var i = 0; i < toggleControls.length; i++) {
toggleControls[i].addEventListener("click", clickHandler);
}
function cloneDiv() {
var elmnt = document.getElementsByClassName("container");
for ( var i=0; i<elmnt.length; i++ ) {
var cln = elmnt[i].cloneNode(true);
}
document.body.appendChild(cln);
document.getElementById("clone").appendChild(cln);
}
window.onload = cloneDiv();

I have a select tag of dynamically added elements. I need to add an event listener to each of the elements in the select tag except the first which:
adds the text of the element to a list,
makes the focus of the list the first element again, and
removes or hides the clicked element.
The first element is a 'none' element which doesn't need any event listener.
I've tried something like
for (var i = 0; i < array.length; i++)
{
var name = array[i];
var selectElement = document.getElementById(selectElementId);
addToSelectNode(document.getElementById(selectElementId), name);
var thisNode = selectElement.childNodes[i];
if (thisNode.value != "none")
{
thisNode.addEventListener("click", function(event)
{
appendNodeToList("artist-list", i);
selectElement.selectedIndex = 0;
selectElement.remove(selectElement.i);
selectElement.style.display = "none";
});
}
}
function addToSelectNode(element, optionText)
{
var newSelectElement = document.createElement("option");
newSelectElement.text = optionText;
element.add(newSelectElement);
}
function appendNodeToList(listId, text)
{
var newNode = document.createElement("LI");
var textNode = document.createTextNode(text);
newNode.appendChild(textNode);
document.getElementById(listId).appendChild(newNode);
}
Didn't work at all though
A few hours later I've solved my own question. The problem stemmed from trying to remove items in the select tag which just wasn't working - I'm nut sure if it's possible but making it disabled solved it. Anyway here's the result.
HTML:
<select id="artist-select-list">
<option value="none">none</option>
</select>
JavaScript:
window.onload = function()
{
var dropdown = document.getElementById("sampleDropdown");
var n = array.length;
// Loop to add to <select> dropdown
for (var i = 1; i <= n; i++)
{
addToSelectNode(dropdown, array[i - 1]);
}
// Loop to add id's to each element in the dropdown
for (var i = 0; i <= n; i++)
{
dropdown[i].id = "selectNum" + i;
}
// Loop to add event listener
for (var i = 0; i < dropdown.length; i++)
{
dropdown[i].addEventListener("click", function(event)
{
// Regardless of which option the user clicks move shown option to "none" (first index in dropdown)
dropdown.selectedIndex = 0;
if (event.target.id != "selectNum0")
{
// Disable once clicked
event.target.disabled = true;
// Do other things here in relation to event.target
}
});
}
}
var array =
[
"sampleText1", "sampleText2"
];
function addToSelectNode(element, optionText)
{
var newSelectElement = document.createElement("option");
newSelectElement.text = optionText;
element.add(newSelectElement);
}
Inside my php while loop I output a div with id divborder, and class div-border
Inside that div i have another div with id title
<div id='divborder' class='div-border'>
<div id='Title'>This is Title</div> <br/> video elements
</div>
I have a JavaScript function that get called when the video ends
for (var i = 0; i < videos.length; i++) {
videos[i].addEventListener("ended", function(event)
{
var divBoader2 = document.getElementsByClassName("divborder")[3];
divBoader2.style.borderColor = "#b1ff99";
}
My Question is how do i change the border color of the div and the title of second div?
I can do it like this:
var divBoader2 = document.getElementsByClassName("divborder")[3];
divBoader2.style.borderColor = "#b1ff99";
which works but its not dynamic
Save the value of value at i in another variable declared with let
for (var i = 0; i < videos.length; i++) {
let index = i; //save the value as let so that its binding stays
videos[i].addEventListener("ended", function(event)
{
var divBoader = document.querySelectorAll("div-border")[index];
divBoader.style.borderColor = "#b1ff99";
}
}
Or if the video elements are within the div-border, then use closest
for (var i = 0; i < videos.length; i++) {
videos[i].addEventListener("ended", function(event)
{
var divBoader = event.currentTarget.closest(".div-border");
divBoader.style.borderColor = "#b1ff99";
}
}
A little less verbose code
[...videos].forEach( s => s.closest( ".div-border" ).style.color = "#b1ff99" )
Try this,
Give class name div-border instead of divborder
for (var i = 0; i < videos.length; i++) {
videos[i].addEventListener("ended", function(event)
{
var divBoader2 = document.getElementsByClassName("div-border")[3];
divBoader2.style.borderColor = "#b1ff99";
}
What you need is probably a videos[i].parentNode instead of document.getElementsByClassName("div-border")[3] (see https://developer.mozilla.org/en-US/docs/Web/API/Node/parentNode)
I got a Script Which makes me onclick showing all Divs with Specific id
This is the Selector
<a onclick="filterGal('simpleCart_shelfItem item Sonnenbrillen')" href="javascript:void(0);">Sonnenbrillen</a>
this is my Script
function filterGal(foo) {
var toHide = document.getElementsByClassName(foo);
for (i = 0; i < toHide.length; i++) {
toHide[i].style.display = 'block';
}
}
So now my question how can i only show specific div with classname and display none the other div with other classnames?
Try this :
function filterGal(foo) {
var toHide = document.getElementsByTagName('div');
for (i = 0; i < toHide.length; i++) {
toHide[i].style.display = 'none';
}
var toShow = document.getElementsByClassName(foo);
for (i = 0; i < toShow.length; i++) {
toShow[i].style.display = 'block';
}
}
Can be improved by skiping in the first loop div which match your classes.
I just show you add jquery tag so you just need to do this :
function filterGal(foo) {
$( "div:not("+foo+")" ).hide();
}
Exemple : http://jsfiddle.net/ACjeZ/1
This is what I would try:
$("div").Hide();
$("." + foo).Show();
I amd working with hiding and showing divs, which have different contents. When i click on a link, i want a div to be shown. But when i click on another link, i want the new content to replace the previous one. Right now, it falls under it instead of replacing it. Any solution?
Javascript
function show(){
var links = {
link1: "content1",
link2: "content2",
link3: "content3",
link4: "content4"
};
var id = event.target.id;
var a = document.getElementsByTagName("a");
document.getElementById(links[id]).style.visibility = 'visible';
}
function init(){
var divs = document.getElementsByTagName("div");
for (i = 0; i < divs.length; i++) {
if (divs[i].className == "div") {
divs[i].style.visibility = 'hidden';
}
}
var a = document.getElementsByTagName("a");
for(i = 0; i < a.length; i++){
a[i].onclick = show;
}
}
window.onload = init;
You need to run the block of code that hides them all before showing the one you want, every time.
Make this:
function hideAll() {
var divs = document.getElementsByTagName("div");
for (i = 0; i < divs.length; i++) {
if (divs[i].className == "div") {
divs[i].style.visibility = 'hidden';
}
}
Remove this code from init() and replace it with a call to hideAll() and add a call to hideAll() at the beginning of show().
In my html code I have a list of these <li> elements:
<li class="liitem" id="183"><span> Google </span><br>
<ul><li><span>gmail.com </span><span id="183" style="float:right;display:none;">delete</span></li></ul></li>
I want this:
When there is a mouseover on a <li> element of the "liitem" class, then set display:block of the span with the same id ( 183 in this case ).
I have writed this code but it's incomplete and I don't know how to do:
var elms = document.getElementsByTagName('li');
for (var i = 0; i < elms.length; i++){
if (elms[i].getAttribute('class') === 'liitem'){
elms[i].onmouseover = function(){
//set display:block
}
elms[i].onmouseout = function(){
//set display:none
}
}
}
you have set an id with the same value id should be unique. so you could add a value to the id to make it diferent for the liitem's id. like.
Just make sure there is no space to be safe between the a and span.
<ul>
<li class="liitem" id="183"><span> Google </span><br>
<ul><li><span>gmail.com</span><span style="float:right;display:none;">delete</span></li></ul>
<ul><li><span>docs</span><span style="float:right;display:none;">delete</span></li></ul>
</li>
</ul>
.
var elms = document.getElementsByTagName('li'),
emls_len = elms.length;
for (var i = 0; i < emls_len; i++){
if (elms[i].className == 'liitem'){
var arr_sub_uls = document.getElementById(elms[i].id).getElementsByTagName('ul');
// for each UL within the liitem
for (var j = 0; j < arr_sub_uls.length; j++){
// assign id's to the span around delete
var actionis = arr_sub_uls[j].childNodes[0].childNodes[1].id = elms[i].id + "_" + j; // elms[i].id is the liitem id and j is the number of uls'
// attach the event handler
addEventHandler(arr_sub_uls[j].childNodes[0],actionis)
}
}
}
function addEventHandler(s, actionis){
s.onmouseover = function(){ document.getElementById(actionis).style.display = "block" }
s.onmouseout = function(){ document.getElementById(actionis).style.display = "none" }
}
see fiddle: http://jsfiddle.net/EW2cm/1/
You can do this:
elms[i].style.display = "block";
and
elms[i].style.display = "none";
