I have a code in PHP that prints HTML elements based on the information we got in the database, so if we have for example 8 products the code will print 8 divs with the following elements inside
here is some code i made
<?php
while($row=$consulta->fetch())
{
?> <img src="<?php echo $row["Imagen"];?>"style="width:12rem;height:12rem;" alt="Scotter" >
<br>
<div>
<h4 id="<?php echo $row["ID_Scooter"]; ?>"> <?php echo $row["ID_Scooter"]; ?> </h4>
<br>
<?php
echo $row["Nombre"];
?>
<br>
<?php
echo $row["Descripcion"];
?>
<br>
<?php
?>
<button onclick="abrir()">Alquilar</button>
<br>
</div>
<?php
}
?>
JavaScript
function abrir(){
var dialog = document.getElementById('favDialog');
dialog.show();
var id=document.getElementById("heres is where im supposed to get the id of the id i clicked");
alert("div id is="+id);
}
php assing ID for example (3,4,5,6,7) but when i click the button inside the div with id=5 it prints the id=3 no matter which button i click
please note that you've set onclick="abrir()" without passing any specific data!
you have got 2 way to do it:
1- passing data with php:
HTML:
abrir(<?php echo $row["ID_Scooter"]; ?>)
and use it in your js :
function abir(id){
let id_scooter = id;
...
}
2- passing clicked element with js:
HTML:
onclick="abrir(this)"
JS:
function abir(el){
let id_scooter = (el).attr(id);
...
}
