Is there a quicker method for writing this code efficiently?
view = + data.items[ 0 ].statistics.viewCount
view1 = + data.items[ 1 ].statistics.viewCount
view2 = + data.items[ 2 ].statistics.viewCount
document.getElementById("views").innerHTML = view;
document.getElementById("views2").innerHTML = view1;
document.getElementById("views3").innerHTML = view2;
Utilizing jQuery to target elements with an attribute that starts with a specific value
var viewCountArr = data.items.map(function(item) {
return item.statistics.viewCount;
});
var elements = $('[id^="views"]');
$.each(elements, function(index, value) {
$(this).html(viewCountArr[index]);
});Below is a revised version with reduced redundancy:
["item1","item2","item3"].forEach(function(val, idx){
document.getElementById(val).innerHTML = data.items[idx].details;
});
Please keep in mind that using the .forEach method requires ES5 or higher compatibility; if you're working with ES3, consider alternatives such as Underscore's _.each, or other available libraries.
if we assume the structure of your data is similar to this:
var data = {
items: [
{statistics: {viewcount: 5}},
{statistics: {viewcount: 346}},
{statistics: {viewcount: 123}}
]
};
then a possible solution could be:
data.items.map(function(el, i){
var idx = 'views' + (i > 0 ? i+1 : '');
document.getElementById(idx).innerHTML = el.statistics.viewcount;
});
