Pass Php Arrays To External Javascript File
I've seen some of the questions about the passing PHP arrays to an external JavaScript file, but I can't understand it. I know how to pass PHP arrays to internal JavaScript files b
Solution 1:
use this code, JS File (test.js)
for(var i=0;i<jArray.length;i++){
alert(jArray[i]);
}
PHP File (test.php)
<?php
$a = array("Apple","Orange","Grape");
?>
<script type="text/javascript">var jArray =<?php echo json_encode($a); ?>;</script>
<script type="text/javascript" src="test.js"></script>
Solution 2:
You cant use php code directly in your external js
file, the given code is,
<?php
$a = array("Apple","Orange","Grape");
?>
<script type="text/javascript">
var jArray= <?php echo json_encode($a); ?>;
for(var i=0;i<3;i++){
alert(jArray[i]);
}
</script>
I think you can change the code as,
//Declaring the array in php
<?php
$a = array("Apple","Orange","Grape");
?>
//Assigning the json encoded format to javascript
<script type="text/javascript">
var jArray= <?php echo json_encode($a); ?>;
</script>
//You can use the jArray in the external js file
<script type="text/javascript" src="externaljsfile.js" >
Solution 3:
You can't pass datas to external javascript file like you do to internals.
But, a solution can be :
<script type='text/javascript'>
// here you retrieve datas from PHP and use them as global from your external
var myArray = <?php echo json_encode($a); ?>;
</script>
<script type='text/javascript' src='externalJavascript.js'></script>
Else, a different solution could be getting datas with an AJAX request from your external file.
