Mystery Elements Appearing When Appending
I have the following PHP and JS:
Solution 1:
You are using for...in to loop over an array, which is not recommended. As a result, you're probably picking up a bunch of properties you didn't mean to loop over and are getting garbage appends as a result.
Use a regular for loop (for (var i = 0; i < array.length; i++)) instead and it should work as expected.
Solution 2:
The for in ... is creating the issue, as it is iterating over the properties of the Array object as well.
Change the for loop to:
$.each(window.depthElems, function(i, a){
$('body').append('<img src="' + a[0] +
'" style="margin-left: ' + a[1] +
'px; top: ' + a[2] +
'px;" data-velocity="' + a[3] +
'" class="depthElem" />');
});
