I'm working in PHP and I have this button, than when clicked, should print something.
I've (unsuccessfully) tried the following:
<?php
echo '<button type="submit" id="enviarRecibos" class="btn btn-primary float-end">Imprimir Lista</button>';
?>
<script>
if(document.getElementById('enviarRecibos').clicked == true){
<?php
echo $listaDatos;
?>
};
</script>
What am I doing wrong?
Note: $listaDatos
is a variable that's already in the page with some content in JSON format.
My Answer:
You cannot directly trigger PHP code from a button click event in JavaScript. However, you can use AJAX to send a request to a PHP script when the button is clicked.
Here is an example of how you can achieve this:
1. Create a button in your HTML file:
html
2. Add a click event listener to the button in your JavaScript file:
javascript
document.getElementById("myButton").addEventListener("click", function() {
var xhr = new XMLHttpRequest();
xhr.open("GET", "your_php_script.php", true);
xhr.send();
});
3. In your PHP script (your_php_script.php), you can then print something:
php
echo "Button clicked!";
?>
When the button is clicked, the JavaScript code will send a GET request to your PHP script, which will then print "Button clicked!".
Make sure to adjust the file paths and names according to your project structure.
