utilizing the getElementById for styling a paragraph within a div

Upon hovering over an image, I am looking to make the paragraph within this div disappear. Here's what I've tried:

$("#One1 img").hover(function(){
    var par = document.getElementById('One1 p');
   par.style.display = "none";
},function(){});

However, I'm encountering the error 'Uncaught TypeError: Cannot read property 'style' of null'

I understand that using getElementById for a div is simply 

var par = document.getElementById('One1');
but how can I target the paragraph inside that div? Any help would be appreciated!

Answer №1

When using document.getElementById()
, keep in mind that it will only retrieve elements with the specified id and not any css selector.

Since jQuery is being utilized, take advantage of the built-in selectors provided by the library.

$("#One1 img").hover(function () {
    $('#One1 p').hide();
}, function () {
    $('#One1 p').show();
});

Answer №2

One way to achieve this effect is by using jQuery:

$("#One1 img").on("mouseenter", function(){
    $("#One p").hide();
});

Answer №3

Utilize JQuery to streamline this process.

$('#One1 img').hover(function(){
    // Utilizing .parent() to retrieve the parent element (#One1)
    // and then hiding all p elements within it
    $(this).parent().find('p').hide();
});

This approach offers greater flexibility, as #One1 can also be a class that is repeated multiple times throughout the page.

Answer №4

It is recommended to use 

document.querySelector("#One1 p")
instead of 
document.getElementById('One1 p');
. The reason being that document.getElementById retrieves the id of an element, while selectors like #One1 p don't work by simply adding a space and then selecting the p element.
