The customized Javascript function generates a unique <li></li> element while simultaneously deleting all other <li></li> elements present on the webpage

The issue at hand revolves around my JavaScript function that generates "blocks" using <ul> and <li> elements. Unfortunately, this function is removing all other <li> elements from the webpage, leaving only an empty <ul></ul> structure in the HTML source.

An attempt was made to assign a different class to the webpage's <ul> and <li> elements, but it had no effect as the <li></li> tags were still being removed by the function.

I am seeking advice on how to prevent this unintended removal of <li></li> elements by the JavaScript function.

A snippet from the problematic JS function:

//Board build up
function setBlocks() {
    bR = 0;
    counts = [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]
    var mR = 5, mC = 6;
    var tempFloor, tempRow, tempBlock;
    var floors = $('ul');
    floors.empty();
    for (var f = 0; f < 4; f++) {
        bM[f] = [];
        for (var r = 0; r < mR; r++) {
            bM[f][r] = [];
            tempRow = $('<li></li>');
        $(floors[f]).append(tempRow);
        for (var c = 0; c < mC; c++) {
            var randomNoRequired = true;
            var randomClass;
            while(randomNoRequired) {
                randomClass = Math.round(Math.random() * 10 + 0);
                if (counts[randomClass] < 6 || bR >= 66) {
                    randomNoRequired = false;
                }
            }

etc etc etc

The relevant HTML code used by the JavaScript function:

<div id="a2">
                    <ul></ul>
                    <ul></ul>
                    <ul></ul>
                    <ul></ul>
                    <a class="x"></a>
                </div>

Another section of HTML where <li></li> elements are being unintentionally removed:

<div id="scoreboard-overview">
        <ul> 
             <li>
             test
             </li>
etc etc etc

I would greatly appreciate any assistance with resolving this issue.

Answer №1

It's likely due to the fact that you are invoking

var buildings = $('ul');
buildings.empty();

UPDATE - For targeting specifically the ul within <div id="b7">, utilize

$('div#b7 ul');

Answer №2

let units = $('ul');
units.empty();

By executing this code, all child elements of each ul will be deleted from the document.

Answer №3

const levels = $('ul');

This script will target all ul elements found on the webpage.

If you specifically need to select only the ul(s) inside of div#a2, you should use:

const levels = $('div#a2 ul');

Answer №4

What is the reason for using jQuery selectors to declare strings? Consider this:

 tempElement = $('<div></div>');

A more concise way would be:

 tempElement = "<div><\/div>"
