Retrieve the identification of a randomly selected div element using an array

I am attempting to implement a right-click function using only JavaScript. My initial plan was to utilize a mouseover function, as shown below:

mysteryDiv.onmouseover=function(){
    if (rightMBclicked === true)
    {
    console.log(mysteryDiv.id);
    }
}

The dilemma I am facing is figuring out how to access 'mysteryDiv'. Below is the function responsible for generating the blocks that I need to interact with, along with some key variables:

var blocknum = 0;
var blockmax = 2500;
var blocks = [];

function createBlocks()
    {
    if (blocknum < blockmax)
    {
    blocknum += 1;
    var block = document.createElement("div");
    block.className = "block"; 
    block.id = "block" + blocknum;
    blocks.push(blocknum);
    block.style.width = block_width + "px";
    block.style.height = block_height + "px";
    block.style.cssFloat = "left";
    //block.style.backgroundColor = "#228B22";
    block.style.backgroundImage="url('textures/grass.jpg')";
    document.getElementById("container").appendChild(block,container.firstChild);
    createBlocks();
    }
    else
    {
    if (blocknum === blockmax)
    {
    createPlayer();
    paused = false;
    }
    }
    }

EDIT:

My objective is to retrieve the ID of the block (mysteryDiv) currently under my mouse cursor.

Answer №1

If you need to manage events for dynamically generated blocks, consider the following approach. Make sure to set rightMBclicked to true for test cases.

//after this line
block.style.backgroundImage="url('textures/grass.jpg')"; 

//here
block.onmouseover = function(e){

    if (rightMBclicked === true)
    {
        console.log(e);
        console.log(this.id);
    }
};

//before this line
document.getElementById("container").appendChild(block, container.firstChild);

Answer №2

Upon initial observation, you may find it necessary to assign the same event handler to all of your div elements.

One possible approach is as follows:

customHandler = function(e)
{
        console.log(e)

}

allDivs = document.getElementsByTagName("div")

for (i in allDivs)
    allDivs[i].onmouseover = customHandler

However, be cautious of event bubbling. It might be beneficial to provide more details on your HTML structure for better assistance.
