I know there are A LOT of Qs on hiding-showing a div: I tried them all but somehow nothing seems to work.
I have a form and on loading the page div 1 shows. Once user hits the "Next" button then div 2 (previously not displayed) needs to show. What I would need help with is get the div 2 displayed upon click of the Next button
here is one of my many attempts:
<div>
table 1
</div>
<button name="next" onclick="javascript:showDiv();"> Next </button>
<script type="text/javascript">
function showDiv() {
div = document.getElemntById('dynamic');
div.style.visibility = "visible";
}
</script>
<div id="dynamic" style="display:none">
table 2
<input type="submit" value="Submit"/>
</div>
</form>
</body>
If anyone at all could help me I would be most grateful!! Thank you
You need to switch between "display:none" and "display:block" to hide and show the div.
Also you function should be document.getElementById instead of document.getElemntById
function showDiv() {
div = document.getElementById('dynamic');
div.style.display = "block";
}
<button name="next" onclick="javascript:showDiv();"> Next </button>
<div id="dynamic" style="display:none">
table 2
<input type="submit" value="Submit"/>
</div>
Confusingly, display: none can't be cancelled out by setting visibility to visible. The display property determines how the layout engine positions the div, and the visibility property determines whether it is rendered. So if you start off the div with
<div id="dynamic" style="visibility:hidden">
It should work fine. I generally don't recommend hiding stuff using display: none because it forces the browser to re-layout the window which can move elements around. Using visibility means that everything stays still.
if(document.getElementById("div1").style.display == "none")
{
document.getElementById("div1").style.display = "";//show it
}
else
{
document.getElementById("div1").style.display = "none";//hide it
}

I have the following div hidden in the head of my site.
<div id="esperaMensaje" class="mensajeEspera" style="display:none;">
<p>Espere un momento...</p>
</div>
That when the user clicks on the button with the class "continue" The div appears, and then hides after 8 seconds.
I tried using jquery which would be the easiest but it didn't work as I am setting it up in prestashop and it is a bit cumbersome as it is using an old version of jquery so I would like to make it work with pure js.
Add an event listener on the button for "click", set the <div> to it's default display property, then after 8 seconds set it back to display: none via setTimeout.
document.querySelector(".continue").addEventListener("click", () => {
const div = document.querySelector("#esperaMensaje");
div.style.display = "";
setTimeout(() => div.style.display = "none", 8000); // 8000ms = 8s
});
<button class="continue">continue button</button>
<div id="esperaMensaje" class="mensajeEspera" style="display:none;">
<p>Espere un momento...</p>
</div>
I want to use JQuery on my Coldfusion application for showing/hiding div elements with checkbox checked/unchecked within the div.
Basically, in a view I show multiple divs elements, every div have also more divs inside, one of these internal divs contains an input type checkbox that could come checked or unchecked.
I also have three buttons in that view 'Active, Inactive, All'. When clicking on Active I want to show all div elements with checkbox checked, not showing the unchecked, and the other way around when clicking on Inactive.
<div class="btn-group ">
<button id="actives" type="button">Actives</button>
<button id="inactives" type="button">Inactives</button>
<button id="all" type="button">All</button>
</div>
<div id="apiDiv">
<cfloop array="#apis#" index="api">
<div class="card card-found">
<div class="card-header">
<cfif Len(api.iconClass)>
<i class="fa fa-fw #api.iconClass#"></i>
</cfif>
#structKeyExists( api, "name" ) ? api.name : api.id#
</div>
<div class="card-body">
<p>#api.description#</p>
</div>
<div class="card-button">
<input class="#inputClass# ace ace-switch ace-switch-3" name="#inputName#" id="#inputId#-#api.id#" type="checkbox" value="#HtmlEditFormat( api.id )#"<cfif ListFindNoCase( value, api.id )> checked="checked"</cfif> tabindex="#getNextTabIndex()#">
<span class="lbl"></span>
</div>
</div>
</cfloop>
</div>
I´m not an expert at all with JQuery. The only thing I have done is what follows and I do not know whether if is a good beggining or not:
$("#actives").click(function (e) {
$("#apiDiv .card").filter(function() {
<!--- code here --->
});
});
Someone please that can help me with it? Thanks a lot in advance!
After your CF code executes, it will generate a .card for each loop iteration of your apis array. So you jQuery code will need a click handler for the #actives button and that will loop through each() iteration of the checkboxes to determine the checked/unchecked state. At that point find the closest() ancestor .card and show()/hide() the .card depending upon the checkbox state.
$("#actives").click(function (e) {
$('input[type=checkbox]').each(function() {
if (this.checked) {
$(this).closest(".card").show();
} else {
$(this).closest(".card").hide();
}
});
});
If you want to do it with jQuery code:
$('#actives').click(function(){
$('#apiDiv').show();
});
Working Fiddle
The code you are probably looking for is in these event handlers for your buttons:
function activesHandler() {
jQuery(".card-button > input:checked").parents(".card.card-found").show();
jQuery(".card-button > input:not(:checked)").parents(".card.card-found").hide();
}
function inactivesHandler() {
jQuery(".card-button > input:checked").parents(".card.card-found").hide();
jQuery(".card-button > input:not(:checked)").parents(".card.card-found").show();
}
function allHandler() {
jQuery(".card.card-found").show();
}
jQuery("#actives").click(activesHandler);
jQuery("#inactives").click(inactivesHandler);
jQuery("#all").click(allHandler);
I reproduced some of your ColdFusion by replacing it with JavaScript and provided a demonstration of the above event handlers in this JSFiddle.
Call the checkbox by its id and when it's checked, write a function to display the divs you want to display:
<input type="checkbox" id="check">
$document.getElementById("check").onclick = function(){
$document.getElementById("div_name").style.display="block"; // block displays the div.
}
I'm quite new to all this but I learned quite quickly, as it's really easy in my opinion. I'm trying to make a button hide a <p> tag that another button spawned. How can make the button (At the bottom of code) make the <p> tag disappear?
<button type="button"
onclick="document.getElementById('date_button').innerHTML = Date()">
Click this button to display the current time!</button><br>
<p id="date_button"></p><br><br>
<button onclick="myFuction()">Click this to hide date.</button>
You have to define the called function and using display:none hide the paragraph
function myFuction() {
document.getElementById('date_button').style.display = 'none'
}
<button type="button" onclick="document.getElementById('date_button').innerHTML = Date();document.getElementById('date_button').style.display='block'">
Click this button to display the current time!</button><br>
<p id="date_button"></p><br><br>
<button onclick="myFuction()">Click this to hide date.</button>
In your case you want to show it again so you need to set its innerHTML to ''. In your case if you will do style.display = 'none'. It will not show <p> again
function myFunction(){
document.getElementById('date_button').innerHTML = '';
}
<button type="button"
onclick="document.getElementById('date_button').innerHTML = Date()">
Click this button to display the current time!</button><br>
<p id="date_button"></p><br><br>
<button onclick="myFunction()">Click this to hide date.</button>
Try this. I think this can help
function myFuction() {
document.getElementById('date_button').style.display = 'none';
}
I will start by telling you that this is my very first Javascript program from scratch. I am trying to make a back button that will go to the previously chosen div in a form (hide the current div and show the previous one the user chose).
The form has multiple paths to follow, paths within paths and not all selectors are buttons. There might be an onchange event or a radio button or even text input (text inputs have a next button to click).
I have had it working where it will hide the current div but show all previous chosen divs. It's now working where it hides the current div but shows nothing.
I have read a bunch of postings here and in other forums but have not found what I need yet. Any help would be greatly appreciated.
You can see the actual site here and I have put up a JSfiddle but for some reason I can't get it working there.
Here is the code from the fiddle:
<div>
<form>
<div id="uno" class="showFirst">
<button onclick="hideUno()">First Button</button>
</div>
<div id="dos" class="hideFirst">
<button onclick="hideDos()">Second Button</button>
</div>
<div id="tres" class="hideFirst">
<button onclick="hidetres()">Third Button</button>
</div>
<div id="quattro" class="hideFirst">
<button onclick="hideQuattroUno()">Fourth Button</button>
<button onclick="hideQuattroDos()">Fifth Button</button>
</div>
<div id="branchUno" class="hideFirst">
<p>First Branch</p>
</div>
<div id="branchDos" class="hideFirst">
<p>Second Branch</p>
</div>
</form>
<button id="backButton" onclick="goToPrevious" class="hideFirst">Back</button>
</div>
.hideFirst {
display: none;
}
function goToPrevious() {
var current = $(".chosen").find(":visible");
$(current).hide();
$(current).prev(".chosen").show();
}
function hideUno() {
$("#backButton").toggle();
$("#uno").toggle();
$("#uno").addClass("chosen");
$("#dos").toggle();
}
function hideDos() {
$("#dos").toggle();
$("#dos").addClass("chosen");
$("#tres").toggle();
}
function hideTres() {
$("#tres").toggle();
$("#tres").addClass("chosen");
$("#quattro").toggle();
}
function hideQuattroUno() {
$("#quattro").toggle();
$("#quattro").addClass("chosen");
$("#branchUno").toggle();
}
function hideQuattroDos() {
$("#quattro").toggle();
$("#quattro").addClass("chosen");
$("#branchDos").toggle();
}
Here are a few of the questions I've reviewed here:
retain show / hide div on multistep form
Hide and Show div in same level
how to show previous div of clicked div in angular.js
show div and hide existing div if open with jQuery?
Show one div and hide the previous showing div
I realize it's not the cleanest code, but as I said this is my first and I am trying to cleanup as I go along and learn new things.
You could make a bit of automatization instead of creating onclick events for each button/select separately.
For "Back" functionality, I'd use an array to store elements "on the fly" at each step, instead of checking visibility later on.
I'll make it this way:
Remove CSS rule display:none for hideFirst class (elements will be hidden using jQuery).
Add an class to the buttons/selects/check-boxes/etc... as event inndicator.
Add data-next attribute (to store id of the element which should be shown on click/change)
HTML:
<div id="firstDiv" class="hideFirst">
<button class="my-btn" data-next="#secondDiv" type="button">Show next<button>
</div>
<div id="secondDiv" class="hideFirst">
<select class="my-select" data-next="#thirdDiv">
<option>Helo World</option>
...
</select>
</div>
...
Script:
$(document).ready(function(){
// hide all 'hideFirst' elements, except the first one:
$('.hideFirst:not(:first)').hide();
// declare 'history' variable as an empty array (it will be used to store 'hideFirst' elements for 'Back' functionality):
var history = [];
// click event for the buttons :
$('.my-btn').click(function(e){
// as the button will submit the form if you're not using type="button" attribute, use this:
e.preventDefault();
showNext($(this));
});
// change event for selects :
$('.my-select').change(function(){
showNext($(this));
});
// Method used to show/hide elements :
function showNext(el){
// check if element has a 'data-next' attribute:
if(el.data('next')){
// hide all elements with 'hideFirst' class:
$('.hideFirst').hide();
// show 'Back' button:
$('#backButton').show();
// show the element which id has been stored in 'data-next' attribute:
$(el.data('next')).show();
// Push the parent element ('.hideFirst') into history array:
history.push(el.closest('.hideFirst'));
}
}
// click event for 'back' button:
$('#backButton').click(function(){
// hide all elements with 'hideFirst' class:
$('.hideFirst').hide();
// remove the last '.hideFirst' element from 'history' array and show() it:
history.pop().show();
// hide 'back' button if history array is empty:
history.length || $(this).hide();
}).hide(); // hide 'back' button on init
});
DEMO
I am adding a div around a link on click of a button. but when i click button multiple times, it adds multiple divs.
<li>
<label> </label>
<div class="deletebutton">
<label> </label>
<div class="deletebutton">
<label> </label>
<div class="deletebutton">
<input type="button" id="ctl00_ContentPlaceHolder1_ctrlAddPhotos_RadUpload1remove1" value="Remove" class="ruButton ruRemove" name="RemoveRow">
</div>
</div>
</li>
How can i make sure that it first checks if there is a div around link and then adds.
I am using following code:
var parentTag = $(".ruRemove").parent().get(0).tagName;
if (parentTag == 'LI') {
$(".ruRemove").wrap("<div class='data deletebutton'></div>");
$(".deletebutton").before("<label></label>");
} else {
var par = $('.deletebutton').parent();
if (par.is('div')) par.remove();
$(".ruRemove").wrap("<div class='data deletebutton'></div>");
var prev = $('.deletebutton').prev();
if (prev.is('label')) prev.remove();
$('.deletebutton').before("<label></label>");
}
it should become this:
<li>
<label> </label>
<div class="deletebutton">
<input type="button" id="ctl00_ContentPlaceHolder1_ctrlAddPhotos_RadUpload1remove1" value="Remove" class="ruButton ruRemove" name="RemoveRow">
</div>
</li>
when i click button. before clicking html is:
<li>
<input type="button" id="ctl00_ContentPlaceHolder1_ctrlAddPhotos_RadUpload1remove1" value="Remove" class="ruButton ruRemove" name="RemoveRow">
</li>
Here is a solution shown in a jsFiddle.
The code story is
HTML
<button id="myButton">My Button</button
JavaScript
$(function() {
$("#myButton").click(function() {
if ($(this).parent().get(0).tagName !== "DIV") {
$(this).wrap("<div class='myDiv'>");
}
});
});
What the code does is register a callback for a button click. When clicked, we ask for the parent of the button that was clicked and ask if the parent node has a tag name of "DIV" meaning it is a <div>. If it is not a div, then we wrap the button in a div and end. On the next call, the detection of the parent being a div will be true and no new div will be added.
Why don't you just use for example a function that does what you want only on the first click?
So only on the first click of that button adds the div, if you click other times the button, it wont do anything. This way you wont add multiple divs.
To do that you could use for example jQuery:
<script type="text/javascript">
$("#firstclick").one("click",function() {
alert("This will be displayed only once.");
});
</script>
You can check even the jQuery API Documentation regarding one:
