Redirect to another page and scroll to specific <div> are not working together

Ok, this is my very first question posted to this forum so please be kind.. :)
I'm using ASP.NET MVC 5 and I am trying to do a two step process when an icon is clicked.
Select the correct page
Scroll down to a certain section on that page.
Here is what I got so far:
<a class="sidebar-brand d-flex align-items-center justify-content-start" >
<div class="notification-bell" style="color:red">
<i class="fas fa-fw fa-bell fa-2x" title="Number of Unread Comments" alert-count=#ViewBag.TotalUnreadComments.ToString() onclick='scrollToElement("CommentSection");'></i>
</div>
</a>
And the Javascript
<script type='text/javascript'>
function scrollToElement(id) {
// Set correct page
window.location.replace("/TodoListDashboard");
//Get target
var target = document.getElementById(id).offsetTop;
//Scrolls to that target location
window.scrollTo(0, target);
}
</script>
The funny thing is that either of these actions work by themselves but they won't work together.
Any ideas would be greatly appreciated!!!

Ok, I feel kind of foolish but I figured out an easy fix...
For this problem, I just created a javascript function and added both items together like this:
<script type='text/javascript'>
function scrollToComments() {
window.location.replace("/TodoListDashboard#CommentSection");
}
</script>
Then I just changed my onclick call to:
<i class="fas fa-fw fa-bell fa-2x" title="Number of Unread Comments" alert-count=#ViewBag.TotalUnreadComments.ToString() onclick='scrollToComments();'></i>

How to attach NGBootstrap tooltip to font awesome icon

Trying to add a tooltip to a font awesome icon in an Angular page. The normal Bootstrap method seems to be ignored so I am trying to use the NGBootstrap method used for adding a tooltip to buttons, but the tool tip never displays. https://ng-bootstrap.github.io/#/components/tooltip/examples
The typical Bootstrap method causes an error of Cannot set property 'title' of undefined when hovering.
<i class="fa fa-info-circle" data-toggle="tooltip" title="Name here"></i>
In the component:
ngafterviewinit() {
$(function() {
$('[data-toggle="tooltip"]').tooltip();
}
};

You can also try using button tag.
<div class="infoCSSClass">
<button class="icon-info" data-container="body" ngbTooltip="Here is tooltip text" #toolTip="ngbTooltip" (click)="toolTip.open()" placement="top"></button>
</div>

This seems to work:
<i id="icon" class="fa fa-1x fa-info-circle" [ngClass]="icon" aria-hidden="true" placement="right" ngbTooltip="tipContent"></i>

On click for child element

I want to trigger an on click event for my <i> tag. I added an ID to it but if i try use:
$("#delete-playlist-song").on("click", function() {
console.log("in"); //doesnt trigger
});
It won't trigger so I want to try a different approach? Something like:
$("master-playlist-entries").find("i.pl-action").on("click", function() {
console.log("in"); //Won't work
});
My HTML code:
<ul id="master-playlist-entries" class="database">
<li id="db-" track-name="James Darren - Goodbye Cruel World" data-path="http://example.com/Cruel%20World.mp3" class="active">
<i style="display:none;" class="fa fa-bars db-action" title="Actions" data-toggle="modal" data-target="#modal"></i>
<i id="delete-playlist-song" class="fa fa-times pl-action" title="Remove Song From Playlist"></i>
<i class="fa fa-music db-icon"></i><span class="sn"> Goodbye Cruel World</span> <span class="bl">James Darren</span></li>
</ul>
What I did try was an onclick event to call a function which worked but you see, I want to grab the data-path information and pass it to that function so I can use: $(this).attr("data-path") which will return a different link each time for different li.
Any help will be appreciated!

Your original code works in a one item snippet, https://jsfiddle.net/TrueBlueAussie/6qhhyxs7/ so I have to guess as your example is incomplete:
It is not shown, but I would guess you have multiple <i> elements with the same id (e.g. id="delete-playlist-song). If that is the case it simply will not find any except the first one as browsers use a fast-lookup cache which can only have one element stored against each ID value. IDs must be unique on a HTML page to work property.
Switch to using classes instead and use a delegated event handler.
https://jsfiddle.net/TrueBlueAussie/6qhhyxs7/1/
e.g.
$(document).on('click', '.delete-playlist-song', function() {
$(this).closest('li').slideUp();
});
Notes:
You should connect delegated event handlers to a non-changing ancestor element, but document is the best default if nothing else is close. Do not use body as it has a bug to do with styling that can cause mouse events to not fire. Use document as your friendly backup as it also exists before DOM ready.

I guess your html is added dynamically - so register the click listener dynamically using this:
$("body").on("click", "#delete-playlist-song", function() {
And for getting the attribute data-path you can use $(this).closest('li').attr("data-path") inside the listener.
See a demo below:
$("body").on("click", "#delete-playlist-song", function() {
console.log($(this).closest('li').attr("data-path"));
});

<i id="delete-playlist-song" class="fa fa-times pl-action" title="Remove Song From Playlist"></i>
<i class="fa fa-music db-icon"></i><span class="sn"> Goodbye Cruel World</span> <span class="bl">James Darren</span>
</li>
</ul>

Sidebar closes when deleting element of array

I'm using mobile angular ui to open and close a sidebar. In this sidebar a user can search for persons and add or remove these from an array.
I have this repeat that shows the array of persons when clicking on the <a ...></> it closes the sidebar:
<li ng-repeat="recipient in persons.recipients">
<span class="wrapper">
<span class="imageWrap">
<span class="initials">
{{recipient.firstName.charAt(0)}}{{recipient.lastName.charAt(0)}} </span>
</span>
<i class="fa fa-trash-o" aria-hidden="true"></i>
<span class="details">
<span class="info">
{{recipient.firstName}} {{recipient.lastName}}
<span class="persnr">{{recipient.employeeID}}</span>
</span>
</span>
</span>
</li>
The above html snippet is from a directive that is in the sidebar.
The removeRecipient($index); function looks like this:
$scope.removeRecipient = function(index) {
$scope.persons.recipients.splice(index,1);
}
The function works but closes the sidebar and I can't figure out why it does this. So each time a user removes a recipient it has to swipe the sidebar open again. How do I keep this sidebar open?

SOLUTION
I solved my problem by adding $event.stopPropagation(); in the ng-click right behind the removeRecipient($index); function.

From doc, there was one line.
You can put ui-turn-off='uiSidebarLeft' or ui-turn-off='uiSidebarLeft'
inside the sidebar to make it close after clicking links inside them.
so may be you can use that or you can use or you can do like below.
e.stopPropagation()
for that you need to pass $event in
<i class="fa fa-trash-o" aria-hidden="true"></i>
so in code, you can write.
$scope.removeRecipient = function(index,e) {
if(e){
e.stopPropagation()
}
$scope.persons.recipients.splice(index,1);
}
I didn't used same tool, but may be this is issue.

Never show two divs at the same time

I'm working on a project where ng-cloak is unavailable due to the way the css files are loaded, so I'm looking for a less worse solution and have tried a few different things.
I never want to show these two icons at the same time. The problem is, the bottom one (angle right) shows up briefly since the promise for the data source is still resolving. How can I make sure these two icons will never show up at once?
<i class=" fa invalid-data-icon fa-angle-down" ng-hide="vm.hideInvalid"
ng-show="vm.data.datasources.length">
</i>
<i class="fa invalid-data-icon fa-angle-right" ng-show="vm.hideInvalid"
ng-hide="vm.data.datasources.length">
</i>
EDIT:
went with this from the accepted answer:
<i class=" fa invalid-data-icon fa-angle-down" ng-class="{'rotate-icon':vm.data.datasources[1].length==0 || vm.hideInvalid}"></i>

First using but ng-show and ng-hide in the same tag is a pretty bad idea.
You should do something like :
<i class=" fa invalid-data-icon fa-angle-down"
ng-show="vm.hideInvalid==false && vm.data.datasources.length==0">
</i>
<i class="fa invalid-data-icon fa-angle-right"
ng-show="vm.hideInvalid==true && vm.data.datasources.length==0">
</i>
Considering that as long your promise is not resvoled you would have initialize hideInvalid and datasources to undefined.

Alternative approach: Only use one icon in your code, and rotate it with a css class:
<i class=" fa invalid-data-icon fa-angle-down" ng-class={'rotate-icon':!!vm.data.datasources.length}></i>
(my Angular skills are a bit rusty, but you get the jist...)
Then in your CSS, something like this:
.rotate-icon {
transform: rotate(-90deg)
}
