尝试将值插入自动生成的元素

Question

I'm trying to insert values to elements which id's are generated automatically:

this code works:

<input type="tekst" id="<?php echo $item->getId();?>">
<script>
    document.getElementById("<?php echo $item->getId();?>").value = 1
</script>

but I don't want to have a static value of 1, I'd like to have the value generated automatically so I'm trying to do something like this:

<script>
    document.getElementById("<?php echo $item->getId();?>").value =<?php getVotesValue($item->getId());?>
</script>

but this wont work,

 function getVotesValue($gifId){
    global $db;
    (line 115)$dislikes = $db->query("SELECT COUNT(*) as dislikes FROM gif_dislikes WHERE gif_id='$gifId'"); //line 115

    $resultArray = $dislikes->fetch_assoc();
    $dislikesAmount = $resultArray['dislikes'];
    echo $dislikesAmount;
}

Answer 1

You aren't echoing getVotesValue, so nothing is assigned to your JavaScript variable.

<script>
    document.getElementById("<?php echo $item->getId();?>").value =<?php echo getVotesValue($item->getId());?>
</script>

However, there's no need for any JavaScript here. Try:

<input type="tekst" id="<?php echo $item->getId();?>" value="<?php echo getVotesValue($item->getId());?>">
