使用for循环将javascript变量插入到json编码的php变量中

Question

I've got several items I'm trying to display within a canvas. I've json my php data to support doing this in javascript.

Now I'm trying to iterate the database names with a for loop so I don't have to write the code for each.

Here's what I've got so far:

for ((var i=2; i<=17; i++) && (var j=3; i<=18; j++)){

if((row.g1c[j]y + row.g1c[j]m != 0) && ((12*row.g1c[j]y + row.g1c[j]m) > (360 + (12*row.O1y + row.O1m)))){

    var g1c[i]w = (360-(12*row.g1c[i]y + row.g1c[i]m)-(12*row.O1y + row.O1m));

} else if (row.g1c[j]y +row.g1c[j]m != 0){

   var g1c[i]w = ((12*row.g1c[j]y + row.g1c[j]m)-(12*row.g1c[i]y + row.g1c[i]m));

} else {}

var g1c[i]x = ((12*row.g1c[i]y + row.g1c[i]m)-(12*row.O1y + row.O1m));
var lineHeight = 15;
var maxWidth = 2.5*(g1c[i]w);
var x = 80+(2.5*(g1c[i]x))+(maxWidth/2);

}

This isn't working and I'm 99.999% sure it has to do with the i and j syntax, but everything I've looked up and tried hasn't worked.

If someone would tell me where my screw-up is, I'd be eternally grateful.

Thanks in advance!

Decided do go down the PHP route vice Javascript to avoid having to redo my database...

I'm creating a for loop for each database column and row...

for ($j=3; $j<=$count; $j++){
    $l = "g1c".$j."m";
    $m = "g1c".$j."y";

I can then use php logic as needed for each row of data that needs to be assessed...

if(($row[$l] + $row[$m]) != 0){
.... do something
}
