如何使用Jquery专门获取循环输入值

del_id = $('.button').attr('rel');
alert(del_id)

PHP:

while ($row=mysqli_fetch_assoc($rs)) {
?>
    <div class="itemsin" >
    <span data-toggle="confirmation" rel="<?php echo $row['id']?>" class="button" id="rmlb">Click to Remove </span> 
    </div>
<?php
}

}

?>

I tried this but it's alerting only the first value out printed by loop please give me a suggestion

First of all, please post corrected and formatted code in future.

Here is what you need:

1. Collected all PHP output data in an JS array or object

2. Create a loop in JS to print all array values.

3. You need to be carefull with alerting each value because it will give a you a popup box for each array item and the annoying popup will never finish. I suggest outpoint them in console to see the result.

Your JS Code:

del_id  = document.querySelectorAll (".button");

for(var i = 0; i < del_id.length; i++){
    attrValue = $(this).attr('rel');
    console.log(attrValue);

    //You can also alert it if you wish to:

    //alert(attrValue);
}
