I have a Javascript function within a row in a foreach loop. I'd like to have it repeat each row and have tried this code. Each row has a element ID baserate which will be converted using the code below.

My problem is that it works only on the first row and doesn't for the rest. I do need some help to solve this, and any help is appreciated.

PHP:

foreach ($alllocs as $allrows) - no need to put complete code here.

JAVASCRIPT: 

<script>     
  for (var i = 0; i < <?php echo $alllocs; ?>.length; i++) { 
    var a = document.getElementById("baserate").value;
    var e = Number(a).toFixed(2); 
    var b = Number(forex.rates.KRW).toFixed(2); 
    var c = e * b;     
    document.getElementById("welkomet").innerHTML = (c).toFixed(2);
  }  
</script>

$alllocs contains an array of PHP objects and you want to access the $alllocs in Javascript? Is that what you meant? –  Aprian 20 hours ago
    
You may want to look at json_encode($value) which converts $value to JSON representation, and JSON.parse(text) which converts JSON text to Javascript Object –  Aprian 20 hours ago

I consider your foreach loop is like this

foreach ($alllocs as $allrows)

where You should replace $alllocs with $allrows in javascript code so the code be like this

<?php
foreach ($alllocs as $allrows){
...
...
?>
<script>     
  for (var i = 0; i < <?php echo $allrows; ?>.length; i++) { 
    var a = document.getElementById("baserate").value;
    var e = Number(a).toFixed(2); 
    var b = Number(forex.rates.KRW).toFixed(2); 
    var c = e * b;     
    document.getElementById("welkomet").innerHTML = (c).toFixed(2);
  }  
</script> 
<?php
...
...
}
?>

cause $alllocs is an array(not a single value)

check this general form of foreach loop

foreach (array_expression as $value){
    statement
}
