将数据从Controller传递给JavaScript

Question

I want to pass data from my Controller to a JavaScript that handles a Google Bar Chart.

composer

$tmp = 6;
return view('pages.template', ['tmp' => $tmp]);

from my template.blade.php I call the Google Chart

<div id="chart_div"></div>

.js file:

var tmp = 6;
var tmp2 = parseInt('{!! $tmp !!}');

var data = google.visualization.arrayToDataTable([
    ['comment1', 'comment2'],
    ["- 6 days", tmp],
    ["- 5 days", tmp2],
    ["- 4 days", 31],
    ["- 3 days", 12],
    ["- 2 days", 10],
    ["- 1 day", 3],
    ["today", 4]

the 2nd bar from Google-Bar-Chart is blank ....

But there should be displayed my variable.

How do I solve this issue?

Answer 1

Just replace :

var tmp2 = parseInt('{!! $tmp !!}');

By :

var tmp2 = parseInt(<?php echo $tmp; ?>);

And it should work.
