Need to display a div when the user clicks the button.
//html-code
<div class="col-md-4">
<h4 class="service-heading">Sociala Medier</h4>
<p class="text-muted">first line of text.</p>
<div class="info-text" style="display:none">
<p class="text-muted">Second line of text.</p>
</div>
<button class="info-button"><span>Läs mer </span></button>
</div>
//js-code
document.getElementByClassName("info-button").addEventListener("click", function(){
document.getElementByClassName('info-text').style.display = "block";
});
Any advice how I can get this to work? Also tested with onclick but that doesn't work either.
You're passing elements classes to the .getElementById function. In short, you could change your HTML to this:
<div class="col-md-4">
<h4 class="service-heading">Sociala Medier</h4>
<p class="text-muted">first line of text.</p>
<div id="info-text" style="display:none">
<p class="text-muted">Second line of text.</p>
</div>
<button id="info-button"><span>Läs mer </span></button>
</div>
And it would work
It's actually "getElementsByClassName" you missed the s and it gets a collection so you need to be specific on which one you are targeting. Given your code, you want the first/only element
https://developer.mozilla.org/en-US/docs/Web/API/Document/getElementsByClassName
https://jsfiddle.net/cbye0ph9/
document.getElementsByClassName("info-button")[0].addEventListener("click", function(){
document.getElementsByClassName('info-text')[0].style.display = "block";
});

I have the below HTML
<div name="taskNotificationsDiv">
<div class="notificationCard">
<span class="taskNotificationClose">x</span>
Test
</div>
<hr>
<div class="notificationCard">
<span class="taskNotificationClose">x</span>
Test
</div>
<hr>
<div class="notificationCard">
<span class="taskNotificationClose">x</span>
Test
</div>
<hr>
</div>
And I have the below script which when x is clicked removes the container from the parent.
$(".taskNotificationClose").click(function (){
this.parentNode.parentNode
.removeChild(this.parentNode);
return false;
});
What I am looking for is also removing the hr which is below the div container..Can someone please have a look and let me know how it can be done.
Here's the fiddle [Fiddle][1]
I tried with the below code to find nearest hr and remove it from the parent but it's throwing an error
var $hr = $(this).next('hr');
this.parentNode.parentNode.removeChild($hr);
Thanks

You can use .next() function. A better approach to solve the problem with JQuery:
$(".taskNotificationClose").click(function (){
$(this).parent().next("hr").remove();
$(this).parent().remove();
return false;
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div name="taskNotificationsDiv">
<div class="notificationCard" style="color:red;">
<span class="taskNotificationClose">x</span>
Test
</div>
<hr>
<div class="notificationCard" style="color:blue;">
<span class="taskNotificationClose">x</span>
Test
</div>
<hr>
<div class="notificationCard" style="color:green;">
<span class="taskNotificationClose">x</span>
Test
</div>
<hr>
</div>
You can move 'hr' tag inside each div. It will solve your problem.
JQuery .next(element) can do this
$(".taskNotificationClose").click(function (){
$(this).parent().next("hr").remove();
$(this).parent().remove();
return false;
});
The reason for your earlier error, is that you removed the first sibling first before calling .next()
I'm trying to get the text of some div within the parent div where button is clicked. This is an example code
<div class="parentDiv" >
<div id="divToFind" style="display:none">text</div>
<div class="btn-group">
<button class="button" type="button" >Remove</button>
</div>
</div>
<div class="parentDiv" >
<div id="divToFind" style="display:none">text2</div>
<div class="btn-group">
<button class="button" type="button">Remove</button>
</div>
</div>
Here parentDiv is repeated couple of times and text of divToFind is different in each parentDiv. Whenever remove button is clicked within the parentDiv I want to get the text of divToFind.
I have tried this
$(this).closest('.parentDiv').children('#divToFind').text();
But nothing is returned
Don't use same IDs in a single document. You should use classes instead. With class, it works fine.
It is mentioned in the spec that there must not be multiple elements in a document that have the same id value.
$(function(){
$("button").on("click", function(){
var t = $(this).closest('.parentDiv').children('.divToFind').text();
console.log(t);
})
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="parentDiv" >
<div class="divToFind" style="display:none">text</div>
<div class="btn-group">
<button class="button" type="button" >Remove</button>
</div>
</div>
<div class="parentDiv" >
<div class="divToFind" style="display:none">text2</div>
<div class="btn-group">
<button class="button" type="button">Remove</button>
</div>
</div>
Yes, Its true, you should not use same Id for 2 elements in an HTML document, However following is the code that can help you to get the text of the div given.
There are 2 ways:
$(this).parent().prev('#divToFind').text();
$(this).parent().prev().text();
prev and next allows us to traverse on the same level. You can provide selectors inside that to get particular element.
In your example its ID, you can update Id to some css class, so that you dont have to have elments with same ID.
I have a <div> which contains a <button>. When this button is clicked, I want this <div> to be hidden and another new <div> to be shown in place of the current <div>. Also, the new <div> contains a <button>, which when clicked opens the old <div>. This will enable me to open one <div> at a time on click of the <button> present in those <div>. Can anyone tell me how to do this in AngularJS?
This picture shows my requirement
<body ng-init="showDiv = true">
<div ng-show="showDiv">
<h1>Div 1</h1>
<button ng-click="showDiv = false">Show Div 2</button>
</div>
<div ng-hide="showDiv">
<h1>Div 2</h1>
<button ng-click="showDiv = true">Show Div 1</button>
</div>
</body>
CodePen: https://codepen.io/RaymondAtivie/pen/OXYRyE
Please try something similar to below: use ng-click and ng-show
<div ng-show="!showDiv">
<button ng-click="showDiv=true"></button>
</div>
<div ng-show="showDiv">
<button ng-click="showDiv=false"></button>
</div>
Using ngShow:
<div ng-show="condition" ng-init="condition = true">
<button ng-click="condition = false">Toggle</button>
</div>
<div ng-show="!condition">
<button ng-click="condition = true">Toggle</button>
</div>
But keep in mind to seperate logic like the toggle in ngClick from the view and put it in the controller.
With my inexperience in jQuery, I'm finding the simplest tasks difficult.
What I attempt to do is show/hide certain messages when a certain icon is clicked. This is my HTML:
<div class="container">
<div class="row">
<div class ="col-md-2 pov_icon">
<div class="pov_icon_small" value="measure">
<i class="fa fa-clock-o"></i>
</div>
<div class="pov_title_small">
MEASURE
</div>
</div>
<div class ="col-md-2 pov_icon">
<div class="pov_icon_large" value="locate">
<i class="fa fa-map-marker"></i>
</div>
<div class="pov_title_large">
LOCATE
</div>
</div>
<div class ="col-md-2 pov_icon">
<div class="pov_icon_small" value="inform">
<i class="fa fa-commenting"></i>
</div>
<div class="pov_title_small">
INFORM
</div>
</div>
<div id="measure" style="display:none" class="pov_description">
<p> Message MESSAGE</p>
</div>
<div id="locate" class="pov_description">
<p> Message LOCATE</p>
</div>
<div id="inform" style="display:none" class="pov_description">
<p> Message INFORM</p>
</div>
</div>
</div>
My JavaScript code that changes the pov icon/title classes works and is currently here:
$('.pov_icon_small , .pov_icon_large').on('click', function () {
$('.pov_icon_large').not($(this)).removeClass('pov_icon_large').addClass('pov_icon_small');
$('.pov_title_large').not($(this).next('div[class^="pov_title_"]')).removeClass('pov_title_large').addClass('pov_title_small');
$(this).toggleClass("pov_icon_small").toggleClass("pov_icon_large");
$(this).next('div[class^="pov_title_"]').toggleClass("pov_title_small").toggleClass("pov_title_large");
});
What I aim to do, is display a certain message (e.g. Message Measure) when the a certain icon pov_icon_small value="measure" is clicked while keeping the others hidden. When the user clicks another icon; that respective message will be displayed and the others will be hidden :
$(document).ready(function(){
$('input[.pov_icon_small]').click(function(){
if($(this).attr("value")=="measure"){
$(".pov_description").not("#measure").hide();
$("#measure").show();
}
if($(this).attr("value")=="locate"){
$(".pov_description").not("#locate").hide();
$("#locate").show();
}
if($(this).attr("value")=="inform"){
$(".pov_description").not("#inform").hide();
$("#inform").show();
}
});
The message-linking JS code doesn't seem to work. Am I doing a small error here? Or should I be preparing the code in a completely different way?
Theres two issues, first your CSS selector input[.pov_icon_small] is not valid. The second is that you are attaching the click function to pov_icon_small which do not have enough height or width for a user to click. I've adjusted the HTML so this binds to the pov_title_small class instead.
You'll want to attach your click function to items have a value, then pass that value as the selector. For pov_title_small I've changed the attribute value to data-value, then the click function uses that to select the ID you want to display. Here is the code:
HTML:
<div class="container">
<div class="row">
<div class ="col-md-2 pov_icon">
<div class="pov_icon_small">
<i class="fa fa-clock-o"></i>
</div>
<div class="pov_title_small" data-value="measure">
MEASURE
</div>
</div>
<div class ="col-md-2 pov_icon">
<div class="pov_icon_large">
<i class="fa fa-map-marker"></i>
</div>
<div class="pov_title_large" data-value="locate">
LOCATE
</div>
</div>
<div class ="col-md-2 pov_icon">
<div class="pov_icon_small">
<i class="fa fa-commenting"></i>
</div>
<div class="pov_title_small" data-value="inform">
INFORM
</div>
</div>
<div id="measure" style="display:none" class="pov_description">
<p> Message MESSAGE</p>
</div>
<div id="locate" style="display: none;" class="pov_description">
<p> Message LOCATE</p>
</div>
<div id="inform" style="display:none" class="pov_description">
<p> Message INFORM</p>
</div>
Javascript:
$(document).ready(function(){
$('[data-value]').bind('click', function(){
$('.pov_description').hide();
$('#'+$(this).attr('data-value')).show();
});
});
You can see it working in this JS Fiddle: http://jsfiddle.net/h97fg75s/
1st : you just need to get a value and convert it to id ..
2nd: like #juvian mentioned $('input[.pov_icon_small]') is not a valid selector
3rd .pov_icon_small its a div not an input so you can use $('div.pov_icon_small') instead
4th: .pov_icon_small doesn't have any value attribute .. .pov_title_small and .pov_title_large those has the value attribute
$(document).ready(function(){
$('div.pov_title_small , div.pov_title_large').click(function(){
var ThisValue = $.trim($(this).attr('value'));
$(".pov_description").not("#"+ThisValue).hide();
$("#"+ThisValue).slideToggle()
});
});
Working Demo
if you need to control it from .pov_icon you have 2 ways
1st: put a value attribute in .pov_icon_small/large
2nd: you can use
$('div.pov_icon_small , div.pov_icon_large').click
and
var ThisValue = $.trim($(this).next('div[class^="pov_title_"]').attr('value'));
I have a div setup like so:
<div class="content">
<button class="show-comments" id="content1"></button>
</div>
<div class="comments-wrapper" id="comment1"></div>
<div class="content">
<button class="show-comments" id="content2"></button>
</div>
<div class="comments-wrapper" id="comment2"></div>
I have the following code:
$('.show-comments').click(function(e){
e.preventDefault();
$('.comments-wrapper').slideToggle('slow');
});
As you would assume, the code works but on a class basis. I'd like for it to open up only the .comments-wrapper of its associated id (i.e. open slideToggle comments2 if content 2 button is clicked and so on and so on).
How would I do this?
$('.show-comments').click(function(e){
e.preventDefault();
$(this).closest(".content").next('.comments-wrapper').slideToggle('slow');
});
Note that this is dependent on the .content element being immediately followed by the .comments-wrapper.
If you have access to modify the html itself, I would suggest adding a wrapper element and then doing the following to avoid the reliance on the exact order of elements:
<div class="wrapper">
<div class="content">
<button class="show-comments" id="content1"></button>
</div>
<div class="comments-wrapper" id="comment1"></div>
</div>
<div class="wrapper">
<div class="content">
<button class="show-comments" id="content2"></button>
</div>
<div class="comments-wrapper" id="comment2"></div>
</div>
$(this).closest(".wrapper").find('.comments-wrapper').slideToggle('slow');
This way, if you add an element between the .content and the .comments-wrapper it does not break the code.
You can do this:
$(this).parent("div").next('.comments-wrapper').slideToggle('slow');
This will find the related div of class .comments-wrapper and slide toggle.
And a fiddle: http://jsfiddle.net/xCJQB/
$('.show-comments').click(function (e) {
e.preventDefault();
var num = this.id.match(/\d+$/)[0];
$("#comment" + num).slideToggle('slow');
});
Demo ---> http://jsfiddle.net/7pkyk/1/
Use this context
$(this).closest('.comments').next('.comments-wrapper').slideToggle('slow');
If it is not the immediate element then you might try this as well
$(this).closest('.comments')
.nextAll('.comments-wrapper').first().slideToggle('slow');
you can add a common class to associate a button with a div.
html:
<div class="content">
<button class="show-comments group1" id="content1"></button>
</div>
<div class="comments-wrapper group1" id="comment1">1</div>
<div class="content">
<button class="show-comments group2" id="content2"></button>
</div>
<div class="comments-wrapper group2" id="comment2">2</div>
javascript:
$('.show-comments').click(function(e){
var associate = $(this).attr('class').match(/group\d+/).pop();
var selector = '.comments-wrapper.' + associate;
e.preventDefault();
$(selector).slideToggle('slow');
});
