Bootstrap 4 modal that contains markdown header link



I'm using the following code to open a bootstrap 4 modal that contains a Markdown header link. The modal opens correctly but does not scroll to the correct header. I think this is because the page loads before the modal opens. Is there an event for triggering the scroll to header? Would that event be within showdownjs (what I'm using) or is it a standard implemented within the browser?


let split_url = location.href.split('#');
$(".modal:has(#" + split_url[split_url.length - 1] + ")").modal('show');





Are you sure $(".modal:has(#" + split_url[split_url.length - 1] + ")") finds your modal? Add this code before that: if ($(".modal:has(#" + split_url[split_url.length - 1] + ")").length == 0)alert('not found');

Yes it finds it because the modal opens correctly it just doesn't scroll to the header.

Scroll to header?! It just shows the modal, why should it scroll to header?

When the markdown is outside of a modal it scrolls automatically. Here is an example url github.com/adam-p/markdown-here/wiki/Markdown-Cheatsheet#images that scrolls to the images header

So your modal content has a named tag and you want to scroll the content of the modal down, right? If yes, you cannot use the #url to scrool to your named tag. Use JQuery scroll.

Here a workaround I eventually came up with.


let split_url = location.href.split('#');
let active_modal = $(".modal:has(#" + split_url[split_url.length - 1] + ")");
let offset_top;
active_modal.modal('show').on("shown.bs.modal", function (event)
setTimeout(function ()
if (typeof offset_top === 'undefined')
offset_top = $("#" + split_url[split_url.length - 1]).offset().top;

active_modal.animate( scrollTop: offset_top , 'slow');
,300)
);



It isn't perfect because the scroll is delayed. I couldn't get it to be instantaneous like it normally is.

Clash Royale CLAN TAG #URR8PPP Firebase Auth - with Email and Password - Check user already registered I want to check when a user attempts to signup with createUserWithEmailAndPassword() in Firebase user Authentication method, this user is already registered with my app. createUserWithEmailAndPassword() 8 Answers 8 To detect whether a user with that email address already exists, you can detect when the call to createUserWithEmailAndPassword () fails with auth/email-already-in-use . I see that @Srinivasan just posted an answer for this. createUserWithEmailAndPassword () auth/email-already-in-use Alternatively, you can detect that an email address is already used by calling fetchSignInMethodsForEmail() (previous called fetchProvidersForEmail() ). fetchSignInMethodsForEmail() fetchProvidersForEmail() When the user trying to create an user with same email address, the task response will be "Response: The email address is already in use by another account." mFirebas...

Clash Royale CLAN TAG #URR8PPP Dynamically update html content plain JS So I have a script bound in my index.html, which literally has to fetch an array of jsons from an api, then dynamically update my page when get response. But as a result I'm getting an as the only update of my page. here is my script fetch(url) .then((resp) => resp.json()) .then((resp) => resp.results.forEach(item => fetch(item.url) .then((response)=> response.json()) .then((response) => pokeArr.push(response)) .catch(console.log) ) ).catch(console.log) const filler = () => if(!pokeArr) return 0 pokeArr.map((i,j)=> return `<tr>$i.name</tr>` ) const pokeindex = () => document.getElementById('a').appendChild(document.createElement(filler())) pokeindex() When I'm consoling it, I can see in the console all the responses I get, so I'm at least doing the fetching part right.

Creating a leaderboard in HTML/JS

Clash Royale CLAN TAG #URR8PPP Creating a leaderboard in HTML/JS I'm trying to create a top 10 leaderboard, for now, I've only implemented 3 players, but I'm coming across an issue. My script doesn't seem to be outputting anything on webpage. The purpose of the script is to compare 3 arrays, player1,player2,and player3 solely based off of score. Which is the 2nd index of each array. I want the script to list the players in order of highest score. This method doesn't really seem to be efficient, especially when I'll have to add 7 more players. Could someone suggest perhaps an easier approach, as well as show me why my script wont output the info. Here's the JS function leaderboard() { var player1 = name:"Thomas",date:"01/23/18",score:"201"; var player2 = name:"Michael",date:"03/24/17",score:"943"; var player3 = Name:"Lisa",date:"06/04/18",Score:"79"; if(player1[2]...
