Experiencing issues with creating HTML using JavaScript?

I'm a JavaScript novice and struggling to figure out what's wrong with my code. Here is the snippet:

var postCount = 0;

function generatePost(title, time, text) {
    var div = document.createElement("div");
    div.className = "content";
    div.id = "post_" + postCount;
    document.getElementById("postcontainer").appendChild(div);

    var h3 = document.createElement("h3");
    div.id = "post_h3_" + postCount;
    h3.innerHTML = title;
    document.getElementById("post_" + postCount).appendChild(div);

    var span = document.createElement("span");
    document.getElementById("post_h3_" + postCount).appendChild(div);
    span.innerHTML = time;

    var paragraphs[] = text.split("||");
    for (var p : paragraphs[] {
        var paragraphCount = 0;
        var h3 = document.createElement("h3");
        document.getElementById("post_p_" + postCount + "_" + paragraphCount).appendChild(div);
        paragraphCount++;
    }
    postCount++;
}

function loadPosts() {
    generatePost("Testing Title", "I don't know", "This is || a paragraph");
}

I've added it using:

<body onload="loadPosts()">

However, nothing appears on the page. I can't see anything in my browser's Inspector either. Is my code being executed? Have I missed an important doStuffNow() function?

Also, if I dynamically add a class to a div using JavaScript, will the CSS rules in style.css apply to it?

Answer №1

In regards to your follow-up inquiry, it is indeed true that the CSS formatting associated with a particular class will be inherited by any object that is assigned the same class.

Answer №2

Your code contains errors that need to be addressed. Have you identified the editor you are using? It may also be helpful to use the browser console to pinpoint any issues on your webpage. Take a look here:

var paragraphs = text.split("||");
for (var p in paragraphs) {
    /*
    *
    * How and where are you utilizing the variable 'p'?
    *
    */
    var paragraphCount = 0;
    var h3 = document.createElement("h3");
    document.getElementById("post_p_" + postCount + "_" + paragraphCount).appendChild(div);
    paragraphCount++;
}
