I'm trying to assign id's to some text fields that's getting created dynamically in a loop.
The div which is in the loop that consists of the text fields.
<!-- DATA ENTERED IN THIS TEXT BOX WILL BE REFLECTED IN ALL THE TEXT BOXES CREATED IN THE LOOP-->
<div class="col-sm">
<h5><span class="badge badge-dark">Add Quantity:</span></h5>
<input class="form-control" type="text" name="add0" id="add0" onkeyup="sync()">
</div>
<!-- SCRIPT FOR REFLECTING DATA -->
function sync()
{
var add0 = document.getElementById('add0');
var add1 = document.getElementById('add1');
var add2 = document.getElementById('add2');
var add3 = document.getElementById('add3');
var add4 = document.getElementById('add4');
var add5 = document.getElementById('add5');
var add6 = document.getElementById('add6');
var add7 = document.getElementById('add7');
var add8 = document.getElementById('add8');
add8.value = add7.value = add6.value = add5.value = add4.value = add3.value = add2.value = add1.value = add0.value;
}
<?php
<!-- GETS AN ARRAY OF DATA SCANNED IN THE PREVIOUS PAGE -->
$strings = explode(PHP_EOL,($_SESSION['grid']));
$sa = [];
foreach ($strings as $s) {
array_push($sa, "'".$s."'");
}
$d=implode(',', $sa);
<!-- SQL QUERY -->
$sql = "select distinct size from items where main_group IN(select distinct main_group from items where addl_item_code_barcode IN ($d)) ORDER BY size";
$result = pg_query($db, $sql);
?>
<div class="row">
<!-- THIS LOOP WILL CREATE 8 DIV'S BECAUSE THERE ARE 8 SIZES 36-50 -->
<?php while($res = pg_fetch_assoc($result)){ ?>
<div class="col-md-2 show-hide">
<input type="text" value="<?php echo $res['size']; ?> " readonly
style="background-color: #F5F5F5;" class="form-control"/>
<!-- // OUTPUT WILL BE GENERATED HERE -->
<div id="addition"></div>
<select class="form-control">
<option>25%</option>
<option>50%</option>
<option>100%</option>
</select><br>
</div>
</div>
<br>
<br>
<button type="submit" value="submit" class="btn btn-primary"><i class="fas fa-paint-brush"></i>Apply</button>
</form>
<?php }?>
<!-- The script that I tried for assigning unique id's -->
$(document).ready(function() {
for( var i=1; i<9; i++) //i<9 because that's the maximum number of
// text fields to be created is 8.
{
$('#addition')
.append('<input class="form-control" type="text" name="add" id="add'+i+'" />');
}
The problem is that this script creates a series of text boxes only in the first iteration of the while loop.
Here this output is creating all the 8 text boxes below the 'size' field ie, '36'. How do I get the 2nd text box below 38 and the 3rd below 42 and so on...
Is there a way only create the id's dynamically and append it in the input area, instead of putting the input itself in the loop like I have done?
var text = ""; for(var i=0;i<11;i++) { text += '<input class="form-control" type="text" name="add" id="add_'+i+'" /></br>'; } $("#addition").html(text);
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <div id="addition"></div>
You can set the id within the while-loop, but you have to set an unique id. Maybe you should include the loop-iterator in the id. Try following example:
<?php while($res = pg_fetch_assoc($result)){ ?>
<div class="col-md-2 show-hide">
<input type="text" id="field<?php echo $res['size']; ?>" value="<?php echo $res['size']; ?> " readonly
style="background-color: #F5F5F5;" class="form-control"/>
<div id="addition"></div> // OUTPUT WILL BE GENERATED HERE
<select class="form-control">
<option>25%</option>
<option>50%</option>
<option>100%</option>
</select><br>
</div><?php }?>
