Troubleshooting issue: Inability to assign classes to child elements within divs of a designated class

Currently, I am facing an issue while attempting to insert divs into multiple divs that share a common class called ".description".
My goal is to assign a unique class to each internal div, but for some reason, this only seems to work for the first div with the specified class.
Here is the code snippet in question:

function addDescriptionFields() {
    var i=0;
    for(i=1; i<=3; i++) {
        $(".description").append("<div></div>");
    }
    $(".description").each(function() {
        $(".description div").eq(0).addClass("game-name");
        $(".description div").eq(1).addClass("game-description");
        $(".description div").eq(2).addClass("game-popularity");
    });
}

As a result, only the first div containing the class ".description" successfully receives the specified classes for its internal divs, while the others do not. I am currently seeking assistance to identify and rectify the mistake in my code. Any input would be greatly appreciated.

Answer №1

The each() loop may not be the most efficient solution in this scenario. This is because within the loop, you are selecting only the first element in the .description collection, instead of the first element in each .description.

To resolve this issue, consider implementing the following code:

function addDescriptionFields() {

    for(var i=1; i<=3; i++) {
        $(".description").append("<div></div>");
    }
    $(".description").each(function() {
        $("div", this).eq(0).addClass("game-name");
        $("div", this).eq(1).addClass("game-description");
        $("div", this).eq(2).addClass("game-popularity");
    });
}

Alternatively, a more efficient approach would be:

function addDescriptionFields() {
    var classes     = ["game-name", "game-description", "game-popularity"],
        description = $(".description");

    $.each(classes, function(_, klass) {
        description.append("<div class='"+klass+"' />");
    }
}
