I have a simple HTML page and I am mapping an array to populate a div with cards. The card alignment was all wrong, so when I inspected it, I saw that there are commas after every card except the last one, which is ruining the alignment. I haven't added these commas in the code. My code:
itemsdiv.innerHTML = items.map(el => {
return (`
<div class="item">
<span class="item-title">${el.name}</span>
<img class="item-image" src=${el.src}>
<div class="item-details">
<span class="item-color">${el.color}</span>
</div>
</div>
` )
})
itemsdiv is an empty div to populate, and items is an array that looks like this:
items = [
{
name: 'T-Shirt',
src: 'Images/Shirt.png',
color: 'blue',
},
{
name: 'Coffee Cup',
src: 'Images/Coffee.jpg',
color: 'red',
}
]
When I inspect it looks something like this:
<div class="itemsdiv">
<div class="item"></div>
","
<div class="item"></div>
","
<div class="item"></div>
</div>
After .map try tagging on .join(" ")
Solution based on @VLAZ's comment:
When you convert an array to a string, it automatically joins the elements with commas between them. Assigning an array to innerHTML converts it to a string.
