How can i give div background color based on count with differences of 3 within while loop

Question

I have a div with several boxes within while loop. I want to give the two alternative div background color. For first 3 boxes i have to give the first color. Then for next 3 boxes i'v to give next color, then again for the next 3 boxes i'v to give the first color and so on.

Clearly i want to give the two colors alternatively for 3 boxes alternatively from first. Can anyone help me for this.

Answer 1

 var count=0;
 $("div").each(function (i) {
         count++;
        if (count%3) {
          this.style.color = "blue";
        } else {
          this.style.color = "black";
        }
      });

Answer 2

var count=0;
if(count%2==0) {
 echo"<div style="background:white;">";
}
else {
echo"<div style="background:pink;">";
}
echo"</div>";

Answer 3

The desired result is:

<div class="white">...
<div class="white">...
<div class="white">...
<div class="blue">...
<div class="blue">...
<div class="blue">...
<div class="white">...

Which mean your code should be:

for ($count = 0 ; $count < 20; $count++) {
    $color = ($count / 3) % 2 ? "blue" : "white";
    echo "<div class='$color'>", "SOMETHING", "</div>";
}

All you're doing is grouping "dividing by 3" then determining if the group is even or odd.

Note: You could easily use a style="background-color:$color" depending on your needs and CSS info.

Answer 4

I don't think he likes this is JS as his tag is PHP

is this what you are looking for;

<div>
<?php
   $numberofResults = '5';   
   for ($i=1; $i<=$numberofResults; $i++){
         if($i % 2 == 0) $style='style="background-color:black"';
         else $style='style="background-color:white"';

         echo '<box'.$i.' ' . $style . '>';
         echo '</box'.$i.'>';
         echo "\n";
   }
?>
</div>

this will yield;

<div>
    <box1 style="background-color:white"></box1>
    <box2 style="background-color:black"></box2>
    <box3 style="background-color:white"></box3>
    <box4 style="background-color:black"></box4>
    <box5 style="background-color:white"></box5>
</div>
