I have an app that has a login page. In order to login the user has the permission to see two voice inside the panel (if user is admin). If user is not admin I’d like to not display this voices. My problem is how to hide and show its. I have the panel inside index.html.This are the voice that I'd like to display or not in order users permission.
<li id="company" display="none">
<a href="/aziende/" class="panel-close" >
<div class="item-content">
<div class="item-media">
<i class="f7-icons ios-only">home</i>
<i class="material-icons md-only">home</i>
</div>
<div class="item-inner">
<div class="item-title">Company</div>
</div>
</div>
</a>
</li>
<li id="users" display="none">
<a href="/users/" class="panel-close">
<div class="item-content">
<div class="item-media">
<i class="f7-icons ios-only">person</i>
<i class="material-icons md-only">account_circle</i>
</div>
<div class="item-inner">
<div class="item-title">Users</div>
</div>
</div>
</a>
</li>
this is app.js
{
name: 'login',
path: '/login/',
url: './pages/login.html',
on:{
pageInit: function(){
app.navbar.hide('.navbar');
if(user.checkPermission() == 'true'){
app.router.navigate('/home/');
}
}
},
},
{
name: 'home',
path: '/home/',
url: './pages/home.html',
on: {
pageInit: function(e, page) {
app.navbar.show('.navbar');
if(user.checkPermission() == 'true'){
addVoicesToNavbar();
}
}
page.router.clearPreviousHistory();
}
},
}
this method said me that Cannot set property ‘display’ of null
function addVoicesToNavbar(){
document.getElementById("company").display = "block";
document.getElementById("users").display = "block";
}
display is not a valid html attribute, it is a CSS property.
So setting display="none" on your <li> in the example doesn't do anything.
Instead in your markup you need to set an inline CSS style like this to initially hide the element:
<li id="users" style="display:none;">
And in your function change that inline CSS style like this to show it:
document.getElementById("users").style.display = "block";
Here is an example of what you could do:
function addVoicesToNavbar(){
companyElement = document.getElementById("company");
companyElement.style.display = "block";
...
}
Hope it helps!

I'm working on an application that lists products/sub products. I'm trying to show the sub products when I click on the chevron. For some reason, I can't get this to work. I've been able to get the flipping of the chevron to work.
Here is my code:
<div class="item">
Product 1
<div style="float: right;"><i class="fas fa-fw fa-chevron-down" onclick="expand(this,event)"></i></div>
<div class="sub-item-list" style="display: none">
<div class="sub-item">
Sub Product 1
</div>
</div>
</div>
function expand(event) {
if ($(event).hasClass("fa-chevron-down")){
setTimeout(function () {///workaround
$(event).removeClass("fa-chevron-down");
}, 10);
$(event).addClass("fa-chevron-up");
$(event).closest('div').next().find("sub-item-list").css('display', 'inherit');
} else {
setTimeout(function () {///workaround
$(event).removeClass("fa-chevron-up");
}, 10);
$(event).addClass("fa-chevron-down");
$(event).closest('div').next().find("sub-item-list").css('display', 'none');
}
};
Can someone tell me that the issue is?
You can use .closest('div.item') to get the closest div and then use .find(".sub-item-list") to find the div which you need to display .
Demo Code :
function expand(event) {
if ($(event).hasClass("fa-chevron-down")) {
setTimeout(function() { ///workaround
$(event).removeClass("fa-chevron-down");
}, 10);
$(event).addClass("fa-chevron-up");
//get closest div with class item -> find class
$(event).closest('div.item').find(".sub-item-list").css('display', 'inherit');
} else {
setTimeout(function() { ///workaround
$(event).removeClass("fa-chevron-up");
}, 10);
$(event).addClass("fa-chevron-down");
//get closest div with class item -> find class
$(event).closest('div.item').find(".sub-item-list").css('display', 'none');
}
};
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="item">
Product 1
<div style="float: right;"><i class="fas fa-fw fa-chevron-down" onclick="expand(this,event)"> >> </i></div>
<div class="sub-item-list" style="display: none">
<div class="sub-item">
Sub Product 1
</div>
</div>
</div>
As you are setting onclick event on <i> tag you can also call parent().next() method instead of closest() to get subitem/product.
Try this example:
function expand(event)
{
if ($(event).hasClass("fa-chevron-down"))
{
setTimeout(function()
{///workaround
$(event).removeClass("fa-chevron-down");
}, 10);
$(event).addClass("fa-chevron-up");
$(event).parent().next().css("display", "block");
}
else
{
setTimeout(function ()
{///workaround
$(event).removeClass("fa-chevron-up");
}, 10);
$(event).addClass("fa-chevron-down");
$(event).parent().next().css('display', 'none');
}
};
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="item">
Product 1
<div style="float: right;">
<i class="fas fa-fw fa-chevron-down" onclick="expand(this, event)">Toggle Chevron</i>
</div>
<div class="sub-item-list" style="display:none">
<div class="sub-item">
Sub Product 1
</div>
</div>
</div>
I just encounter a problem I have written a directive but its not getting update, I dont know why, in console it does change but in directive it does not.
Here is my directive
mainControllers.directive('mallsproduct', function () {
return {
restrict: 'E',
scope: {
productInfo: '=info',
linkid: '=linkid'
},
templateUrl: 'directives/dashboard_product.html'

Here is my `html`

<div class="active tab-pane" ng-if="linkid === '3'" >
<malls-product info="$root.mostviewed_products" linkid="linkid"></malls-product>
</div>
<!-- View Profile-->
and This is the api which does show the result in console.
$scope.global_pagecount = 1;
$scope.active_product = function () {
$http.get($rootScope.baseurl + 'abc?&page=' + $scope.global_pagecount,
{headers:
{'Content-Type': 'application/x-www-form-urlencoded',
'Authorization': $rootScope.keyword_auth_token, 'Accept-Language': $cookies.get('type')}
})
.success(function (data) {
//$scope.active_product_pageCount = data._meta.pageCount;
if ($scope.global_pagecount === 1) //I know for sure the first page of pagination is 1
{
$scope.active_products = data;
}
if ($scope.global_pagecount > 1) // If user click load more global count gets incremented and new results push in active_producst
{
/* for loading new results Pagination Applied */
for (var times = data.items.length - 1; times >= 0; times--) {
$scope.active_products.items.push(data.items[times]);
}
}
console.log($scope.active_products);
})
.error(function (data) {
// console.log(data);
});
};
What is the issue, why it is not getting update, If I use rootscopethen it works fine, obviously it has too, but not with $scope.
Note : when scope.global_pagecount value is equal to 2 i get new results but not in directive only in console. By default scope.global_pagecount has value equal to 1.
You don't use your directive correctly. You define it as:
mainControllers.directive('mallsproduct'
Which means you should use it as:
<mallsproduct ..>
Or define your directive camelcased:
mainControllers.directive('mallsProduct'
Then you can use it as you do now:
<malls-product ..>
This is because of the Isolated scope doesn’t know anything about its parent scope. You just created a directive with an isolated scope.
To access any parent scope data, we need to pass the scope data to our directive explicitly. This is achieved by setting properties on the scope object in the DDO.
Another important thing is that, these properties also MUST be set as the attributes of the directive html element.
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);

<div class="menu-item">

<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')

Your first problem is that you are creating multiple elements with identical id properties. This makes your HTML invalid.
Here is the problem code:
#foreach (var item in Model)
{
<div id="#item.MessageId" class="message-item">
...
#foreach (var item in Model)
{
<div class="hide message-content" id="#item.MessageId">
...
For each message in your model, this will create 2 <div> elements whose id has the value of the #item.MessageID variable. The second of these is and illegal element because it has the same ID as an earlier element. You will need to make these <div>s have unique IDs.
The second problem is:
When you run
var content = message.find('.message-content:last').html($('#id-message-content').html());
this part:
$('#id-message-content').html()
cannot find anything because there is no element whose id is "id-message-content". Also every time you open the message, you are appending another "message-content" div into the message-item. This is not necessary.
To fix these issues, you can change the code like this:
First loop:
#foreach (var item in Model)
{
<div data-messageid="#item.MessageId" class="message-item">
...
<span class="summary">
<span class="text">
#item.Subject
</span>
</span>
<div class="message-content" hidden></div>
...
Second loop:
#foreach (var item in Model)
{
<div class="hide message-content" id="message-content-#item.MessageId">
...
jQuery:
$('.message-list .message-item .text').on('click', function () {
var message = $(this).parents('.message-item');
//if message is open, then close it
if (message.hasClass('message-inline-open')) {
message.removeClass('message-inline-open').find('.message-content').hide();
return;
}
$('.message-container').append('<div class="message-loading-overlay"><i class="fa-spin ace-icon fa fa-spinner orange2 bigger-160"></i></div>');
setTimeout(function () {
$('.message-container').find('.message-loading-overlay').remove();
message.addClass('message-inline-open');
var content = message.find(".message-content");
content.show();
content.html($('#message-content-' + message.data("messageid")).html());
//remove scrollbar elements
content.find('.scroll-track').remove();
content.find('.scroll-content').children().unwrap();
content.find('.message-body').ace_scroll({
size: 150,
mouseWheelLock: true,
styleClass: 'scroll-visible'
});
}, 500 + parseInt(Math.random() * 500));
});

I'm retrieving an array filled with user data. They should be displayed in a ul. One of the fields is the prefix for every user as an html code like this <span class="red-text">[Admin]</span>. But when I try to append the li element it renders the html code instead of the red version of the span.
My json code:
{
"users":[
{
"id":"1",
"usrname":"YannickFelix",
"email":"example#gmail.com",
"lvl":"4",
"prefix":"<span class=\"red-text\">[Admin]<\/span>"
}
]
}
And my javascript:
listElemTmplt = `
<li class="collection-item avatar">
<i class="material-icons circle {"{{color}}"}">person</i>
<span class="title">{"{{usrname}}"}</span>
<p>{"{{prefix}}"} {"{{usrname}}"} | {"{{email}}"}
</p>
<span class="secondary-content">
<a class="waves-effect waves-circle" href="users.php?action=edit&uID={"{{id}}"}">
<i class="material-icons grey-text text-darken-1">create</i>
</a>
<a class="waves-effect waves-circle waves-red modal-trigger" href="#modal{"{{id}}"}">
<i class="material-icons grey-text text-darken-1">delete</i>
</a>
</span>
<div id="modal{"{{id}}"}" class="modal">

</li>
`;
template = Handlebars.compile(listElemTmplt);
finishedString = [];
$.getJSON("**url**", function (data) {
console.log(data);
$("ul#users").html("");
data["users"].forEach(function (element, index, array) {
html = template({"{"}id: element["id"], usrname: element["usrname"], email: element["email"], prefix: element["prefix"]{"}"});
$("ul#users").append(html);
});
});
The example item in the List. [Admin] should be red and without the html code
Handlebars escapes the values you give to it when using {{prefix}}. When you want to use raw HTML you have to use {{{prefix}}} to tell it not to escape it.
