I am experiencing an issue with querySelectorAll.
Below is my code snippet:
$(window).load(
function() {
// Add animations
var wwa = document.querySelectorAll(".wwa-box");
if (window.innerWidth > 992) {
wwa.classList.add("bounceIn");
}
// WOW init
new WOW().init();
}
);
Console Output:
TypeError: wwa.classList is undefined
I aim to assign the class .bonuceIn to all elements with the class name .wwa-box.
The reason behind this is that the variable wwa is a collection of elements. To apply a certain class to each element in the collection, you can use a simple loop as shown below. Take a look at this example on jsfiddle
for (let i = 0; i < wwa.length; i++){
wwa[i].classList.add("bounceIn");
}
The issue arises because the variable wwa is a type of NodeList. If there is just one element with the class wwa-box, you can utilize
document.querySelector(".wwa-box");.wwa-box.
Since it is a nodeList collection, you must iterate through each item individually in order to set the classList. So ensure to loop through all of them and apply the necessary modifications.
var boxes = document.querySelectorAll(".wwa-box");
for (var j=0; j<boxes.length; j++) {
boxes[j].classList.add("bounceIn");
}
According to the console:
There seems to be a TypeError: wwa.classList is undefined
Is this property actually associated with wwa? Perhaps it would be beneficial to insert a debugger and explore its properties?
Referencing the alternative solution, proceed to the subsequent index and employ a for loop to navigate and assign the class.
