I have a javascript function which has some parameters (an array). I want to call it inside php. Following is my code
<script type="text/javascript">
<?php
$task_list=array();
foreach($tasks as $row2){
$task_list=$row2;
}
echo "display_diagram(".$task_list.");";
?>
function display_diagram(var1){
.........................
.........................
}
When I call it without any parameter it is working (I could displayed the content in javascript function. But when I give the parameter( it is an array it dose not working. Could you give this a solution?
The usual practice here is to create a separate PHP file that outputs JSON data and fetch that data using an AJAX request. Below is an example of including JSON data inline, but I wouldn't typically recommend doing it like this, especially if the data is quite large.
Use json_encode() to convert a PHP variable into something that can be used in JavaScript. With an associative array, you'll get a JavaScript object like {"a":1,"b":2,"c":3,"d":4,"e":5}. With a non-associatve array, you'll get a JavaScript array like [1,2,3,4,5].
<script>
<?php
$tasks = array(
145 => array(
'name' => 'Sorting Task',
'owner' => 'user1'
),
2343 => array(
'name' => 'Processing Task',
'owner' => 'user2'
),
7266 => array(
'name' => 'Another Task',
'owner' => 'user1'
),
8373 => array(
'name' => 'Lorem Ipsum Task',
'owner' => 'user3'
)
);
echo 'display_diagram(' . json_encode($tasks) . ')';
?>
function display_diagram(tasks) {
$.each(tasks, function (id, task) {
console.log('Task #' + id + ': name=' + task.name + ', owner=' + task.owner);
});
}
</script>
The JavaScript above uses jQuery to process the object. It should output the following in the JavaScript console:
Task #145: name=Sorting Task, owner=user1
Task #2343: name=Processing Task, owner=user2
Task #7266: name=Another Task, owner=user1
Task #8373: name=Lorem Ipsum Task, owner=user3
