Question

var dd = Math.floor(Math.random()*99);    
$('#a'+ dd + 'b'+ dd + 'c'+ d ).css({...});



for (var i=1; i<100; i++) {
 for (var ii=1; ii<100; ii++) {
  for (var iii=1; iii<100; iii++) {
   $('#a'+ i + 'b' + ii + 'c' + iii).css({...});
  }
 }
}

I need help changing the div css which id number like div#a + num + b + num + c + num, (num range from 1-99 so that like div#a11b35c9, div#a98b23c17 …)

Random cannot delimit all the number range from (1-99) foreach make judge slowly. How do I make it more efficient? (It is also hard to add a class for each div) Thanks.

Answer 1

divArray=document.getElementsByTagName('div');
for (mydiv in divArray) {
    if (mydiv.id.match(/^a\d{1,2}b\d{1,2}c\d{1,2}$/)) {
        // make your change here
    }
}
