On button click, hide elements and display the one I need - javascript

Whenever I click on the first button, I want to hide rest of elements and display the title with description for first item, I want to do this for the rest items as well. Whenever I am trying to do this, I am not able to target all elements in my function. Can someone assist? Also should I add to the buttons something like data-* and based on that display/show the div?
class MyClass {
constructor() {
this.items = document.querySelectorAll('.test');
this.btn = document.querySelector('.click');
console.log(this.items); //logs elements
this.btn.addEventListener("click", this.testFunc);
}
testFunc() {
console.log(this.items); //undefined ?
}
}
new MyClass();
.test {
display: none;
}
<div class="item first">
<h3>Item-1</h3>
<p class="test">
dadwa dwao dawkda
</p>
</div>
<div class="item second">
<h3>Item-1</h3>
<p class="test">
dadwa dwao dawkda
</p>
</div>
<div class="item third">
<h3>Item-1</h3>
<p class="test">
dadwa dwao dawkda
</p>
</div>
<button class="click">
Test
</button>
<button class="click">
Test
</button>
<button class="click">
Test
</button>

The following update to your MyClass should do the trick.
The main change is that you attach an event listenter to all buttons (changed querySelector('.click') to querySelectorAll('.click'). And the helper function showItem takes an index which is which item to show (and hide all the rest).
I'm using the hidden attribute to show/hide elements. You could instead add or remove a class from the item that has the display: none.
class MyClass {
constructor() {
this.items = document.querySelectorAll(".test");
this.btns = document.querySelectorAll(".click");
this.items.forEach((item, index) => {
item.setAttribute("hidden", true);
this.btns
.item(index)
.addEventListener("click", (ev) => this.showItem(index));
});
}
showItem(idx) {
this.items.forEach((item, index) => {
if (index === idx) {
item.removeAttribute("hidden");
} else {
item.setAttribute("hidden", true);
}
});
}
}
new MyClass();
<div class="item first">
<h3>Item-1</h3>
<p class="test">
dadwa dwao dawkda
</p>
</div>
<div class="item second">
<h3>Item-2</h3>
<p class="test">
dadwa dwao dawkda
</p>
</div>
<div class="item third">
<h3>Item-3</h3>
<p class="test">
dadwa dwao dawkda
</p>
</div>
<button class="click">
Test 1
</button>
<button class="click">
Test 2
</button>
<button class="click">
Test 3
</button>

Trying to add a click event to individual elements but want them to execute one at a time

I have three div elements on a page and when each one is clicked they are supposed to disappear one at a time. Right now when I click one div element, they all disappear as a group. How do I make them disappear one at a time?
HTML
<div id=parentlist>
<div id="alert">
<span class="closebtn">×</span>
<strong>Error!</strong>
</div>
<div id="alert2">
<span class="closebtn">×</span>
<strong>Success!</strong>
</div>
<div id="alert3">
<span class="closebtn">×</span>
<strong>Warning!</strong>
</div>
</div>
JAVASCRIPT
document.addEventListener("click", function(){
document.getElementById('alert').style.display = 'none';
document.getElementById('alert2').style.display = 'none';
document.getElementById('alert3').style.display = 'none';
});
First create an Array and then add an event listener to every element in the array using Array.forEach method of ES6.
The Code:
window.onload = function() {
var divs = Array.from(document.querySelectorAll('.alerts'));
divs.forEach(div => div.addEventListener('click', function() {
div.style.display = 'none';
}));
}
<div id=parentlist>
<div id="alert" class='alerts'>
<span class="closebtn">×</span>
<strong>Error!</strong>
</div>
<div id="alert2" class='alerts'>
<span class="closebtn">×</span>
<strong>Success!</strong>
</div>
<div id="alert3" class='alerts'>
<span class="closebtn">×</span>
<strong>Warning!</strong>
</div>
</div>
You can try using timeout like this
document.addEventListener("click", function() {
document.getElementById('alert').style.display = 'none';
setTimeout(() => {
document.getElementById('alert2').style.display = 'none';
setTimeout(() => {
document.getElementById('alert3').style.display = 'none';
}, 500);
}, 500);
});
<div id=parentlist>
<div id="alert">
<span class="closebtn">×</span>
<strong>Error!</strong>
</div>
<div id="alert2">
<span class="closebtn">×</span>
<strong>Success!</strong>
</div>
<div id="alert3">
<span class="closebtn">×</span>
<strong>Warning!</strong>
</div>

selecting elements javascript

I'm making a script that will notify you when someone is online on whatsapp web and i have this:
var onlineCheck = window.setInterval(function() {
var y = document.getElementsByClassName("emojitext ellipsify")[19];
if (y == null) {
console.log("online notification failed");
} else {
if (y.innerText === 'online') {
new Notification("contact is online");
window.clearInterval(onlineCheck);
}
}
},1000);
now the problem is that i'm selecting an element by the class "emojitext ellipsify" th 19th and if someone texts me another element with the class "emojitext ellipsify" will be made and the 19th won't be the status anymore, so i want to know if i can select an element with the same method from css which is : element>element
like this (div#main>header.pane-header pane-chat-header>div.chat-body>div.chat-status ellipsify>span.emojitext ellipsify)
or any other possible way.
var onlineCheck = window.setInterval(function() {
var y = document.getElementsByClassName("emojitext ellipsify")[19];
if (y == null) {
console.log("online notification failed");
} else {
if (y.innerText === 'online') {
new Notification("contact is online");
window.clearInterval(onlineCheck);
}
}
}, 1000);
<header class="pane-header pane-chat-header">
<div class="chat-avatar">
<div class="avatar icon-user-default" style="*somestyle*">
<div class="avatar-body">
<img src="*srcpath*" class="avatar-image is-loaded">
</div>
</div>
</div>
<div class="chat-body">
<div class="chat-main">
<h2 class="chat-title" dir="auto">
<span class="emojitext ellipsify" title="*person'sname*"><!-- react-text: 3216 -->*person'sname*<!-- /react-text --></span>
</h2>
</div>
<div class="chat-status ellipsify">
<span class="emojitext ellipsify" title="typing…"><!-- react-text: 3219 -->*the info that i need to get(typing…)*<!-- /react-text --></span>
</div>
</div>
<div class="pane-chat-controls">
<div class="menu menu-horizontal">
<div class="menu-item">
<button class="icon icon-search-alt" title="Search…"></button>
<span></span>
</div>
<div class="menu-item">
<button class="icon icon-clip" title="Attach"></button>
<span></span>
</div>
<div class="menu-item">
<button class="icon icon-menu" title="Menu"></button>
<span></span>
</div>
</div>
</div>
</header>
What you are looking for is document.querySelectorAll
With that function, you can select elements with a selector, the same used with css. So, you could do this:
document.querySelectorAll(".emojitext.ellipsify")
Or put a better selector, in order to get the desired elements, and not others.
Your example would be:
document.querySelectorAll("div#main>header.pane-header pane-chat-header>div.chat-body>div.chat-status ellipsify>span.emojitext.ellipsify")
You could use JQuery, much simpler
$('parent > child')

how to dynamically set text to an element in jquery

i have an onclick function that that calls a changeName function anytime a click event on that element happens.
function changeName() {
var frag = $('<span class="Name">change me</span>');
$( ".list" ).prepend(frag);
var x =[];
$('.ch-gname').each(function(index, obj)
{
x.push($(this).text());
for(i=0; i<x.length; i++) {
$('.Name').text(x[i]);}}});
$('#action').on('click', changeName);
HTML
<div>
<a href="#0" class="cb-pgcar"</a>
<span class="ch-gname">Greenhouse</span>
</div>
<div>
<a href="#0" class="cb-pgcar"</a>
<span class="ch-gname">tree house</span>
</div>
<div>
<a href="#0" class="cb-pgcar"</a>
<span class="ch-gname">light house</span>
</div>
<div class="list">
</div>
<div class="list">
</div>
<div class="list">
</div>
i want to able to change the text of the class Name to the text of class ch-gname. My function gives me only the last text text(lighthouse) for the three links.Any help please
The function changeName() has $('#action').on('click', changeName); but i do not see any element with id 'action'. Anyhow i've made necessary changes in order to make it work.
Added Action id to the elements
Changed the $('.Name').text(x[i]); to $('.Name')[i].innerHTML = x[i];
Look at the below example
function changeName() {
var frag = $('<span class="Name">change me</span>');
$(".list").prepend(frag);
var x = [];
$('.ch-gname').each(function(index, obj) {
x.push($(this).text());
});
for (i = 0; i < x.length; i++) {
$('.Name')[i].innerHTML = x[i];
}
}
$('#action').on('click', changeName);

angularJS Custom directive functionality works using ng-click but not using ng-mouseOver

Requirement goes like this :- I have left navigation panel which has to be in sync with the items added in the main active view by the user and has to display in tree structure. Basic idea is to provide context aware sub-view that change based on active view.
Custom directive used to display tree structure: https://github.com/nickperkinslondon/angular-bootstrap-nav-tree/blob/master/src/abn_tree_directive.js
my HTML code: (using ng-click)
<div class="add-data-request-panel" style="min-height:1071px;"
ng-click="expandPanel()">
<ul>
<li class="icon-drd icon-drd-diactive" ng-if="panelCollapse" ></li>
<li class="icon-pie-chart icon-pie-active" ng-if="panelCollapse"></li>
<li class="icon-publish-req" ng-if="panelCollapse"></li>
<li class="icon-view-changes" ng-if="panelCollapse"></li>
</ul>
</div>
<div class="data-slider-panel" style="min-height:1071px;display" ng-if="panelExpand">
<div class="data-slider-row mtop" ng-click="collapsePanel()">
<div class="slider-row-left">
<span class="first-char" >S</span>
<span class="second-char">ection</span>
</div>
<div class="slider-row-right">
<div class="icon-drd icon-drd-diactive">
</div>
</div>
</div>
<div class="data-slider-row">
<div class="slider-row-left">
Section2
<div class="sub-slider-row-left">
<abn-tree tree-data="mainArrayObj"></abn-tree> // passing data to tree directive
</div>
</div>
<div class="slider-row-right">
<div class="icon-pie-chart icon-pie-active">
</div>
</div>
</div>
<div class="data-slider-row" ng-click="collapsePanel()">
<div class="slider-row-left">
Section3
</div>
<div class="slider-row-right">

<div class="slider-row-right">
<div class="icon-view-changes">

</div>
</div>
</div>
JS implementation in my controller
$scope.panelExpand = false; //setting default flag
$scope.panelCollapse = true; //setting default flag
$scope.expandPanel = function() {
$scope.panelExpand = true;
$scope.panelCollapse = false;
$scope.mainArrayObj = []; // array that holds the data passed in html to custom directive
initialJsonSeparator($scope.model.Data); // method used for iteration
};
$scope.collapsePanel = function() {
$scope.panelExpand = false;
$scope.panelCollapse = true;
};
my HTML code: (using ng-mouseover which is not working and displaying the data passed to navigation bar)
<div class="add-data-request-panel" style="min-height:1071px;" ng-mouseover="hoverIn()"
ng-mouseleave="hoverOut()">
<ul>
<li class="icon-drd icon-drd-diactive"></li>
<li class="icon-pie-chart icon-pie-active"></li>
<li class="icon-publish-req"></li>
<li class="icon-view-changes"></li>
</ul>
</div>
<div class="data-slider-panel" style="min-height:1071px;display"
ng-mouseover="hoverIn()" ng-mouseleave="hoverOut()" ng-show="hoverEdit">
<div class="data-slider-row mtop">
<div class="slider-row-left">
<span class="first-char">S</span>
<span class="second-char">ection1</span>
</div>
<div class="slider-row-right">
<div class="icon-drd icon-drd-diactive">

<div class="sub-slider-row-left">

<div class="slider-row-left">
Section4
</div>
<div class="slider-row-right">
<div class="icon-view-changes">
</div>
</div>
</div>
</div>
js Implementation for the ng-mouseOver: (while debugging all the iteration and methods executed as expected)
$scope.hoverIn = function() {
this.hoverEdit = true;
$scope.mainArrayObj = []; // array that holds the data passed in html to custom directive
initialJsonSeparator($scope.model.Data); //method used to iterate the data
};
$scope.hoverOut = function() {
this.hoverEdit = false;
};
Any solution to this issue would be of gr8 help. If there is any other better approach other than the ng-mouseOver and ng-mouseLeave to implement hover, please do let me know.

Search data on click event of button using smart table

I am very new to the smart table. I have gone through its documentation on Smart Table.
But the I haven't found how to bind data on click event in smart table?
Code is very big but I am trying to post it here.
<div class="table-scroll-x" st-table="backlinksData" st-safe-src="backlinks" st-set-filter="myStrictFilter">

and my js code is here.
module.controller('backlinksController', [
'$scope','$filter', 'mcatSharedDataService', 'globalVariables', 'backlinksService',
function ($scope,$filter, mcatSharedDataService, globalVariables, backlinksService) {
$scope.dataExistsValues = globalVariables.dataExistsValues;

}
]);
module.filter('myStrictFilter', function ($filter) {
return function (input, predicate) {
return $filter('filter')(input, predicate, true);
}
});
But It is working fine with the direct search on textbox.
but according to the requirement I have to perform it on button click.
Your suggestions and help would be appreciated.
Thanks in advance.
You can search for a specific row by making some simple tweaks.
add a filter to the ng-repeat, and filter it by a model that you will insert on the button click, like so: <tr ng-repeat="row in rowCollection | filter: searchQuery">
in your view, add that model (using ng-model) to an input tag and define it in your controller
then pass the value to the filter when you click the search button
here's a plunk that demonstrates this
you can use filter:searchQuery:true for strict search
EDIT:
OK, so OP's big problem was that the filtered values wouldn't show properly when paginated, the filter query is taken from an input box rather then using the de-facto st-search plug-in, So I referred to an already existing issue in github (similar), I've pulled out this plunk and modified it slightly to fit the questioned use case.
