Looking at your code you do:<\/p>\n

var names = (\"1200voc\")\n<\/code><\/pre>\n
then try to access names<\/code> as an array.<\/p>\n
So this:<\/p>\n
for (x = 0; x < names.length; x++) {\n    var prof = document.getElementById(names[x]);\n    prof.src=\"https:\/\/stackoverflow.com\/questions\/48342902\/engine\/images\/proffesion\/\" + names[x] + '.png';  \n}\n<\/code><\/pre>\n
Means that names[0]<\/code> will return 1<\/code>, names[1]<\/code> will return 2<\/code>, names[2]<\/code> will return 0<\/code> and so on…<\/p>\n
Now there’s is no element with id of 1<\/code> or 2<\/code>… so when you do:<\/p>\n
var prof = document.getElementById(names[x]);\n<\/code><\/pre>\n
you get your error.<\/p>\n
What you want is an array of names, so what you should do is:<\/p>\n
var names = [\"1200voc\"]\n<\/code><\/pre>\n
This way you can properly loop through names<\/code> as an array in the format you want.<\/p>\n<\/p><\/div>\n
<\/div>\n<\/div>\n
