Set JavaScript variable from PHP
javascript, php
Solution
If you want to set the variable when the page loads, you could use something like this in the PHP code:
<script type="text/javascript">var strUser = <?php echo json_encode($someVariable); ?>;</script>
Just make sure to remove the later variable declaration from the JavaScript.
If you want to set the variable after the page loads, you'll have to use an AJAX call to ge the value from the server.
Problem
How I can set the JavaScript variable strUser from PHP? I am using the following code: ``` <script> function val() { var e = document.getElementById("ali"); var strUser = e.options[e.selectedIndex].text; } </script> brand<select id="ali" onChange="val()"> <?php $brand=modsearchkhodroHelper::retrieve(); foreach($brand as $item) { ?> <option value="<?php echo $item['brand']?>" selected="<?php $id=$item['brand']?>"> <?php echo $item['brand']?> </option> <?php } echo "</select>"; ?> ```
