在javascript函数中打印json数据，将引号替换为“”

Question

I'm using Laravel Framework since a couple of weeks now.

I have a strange problem, I would like to convert a PHP 2D array into a JavaScript object, so I used in my controller json_encode() something like :

$arr['ping']    = array_values($arr['ping']);
$arr['doc']     = array_values($arr['doc']);

$data = json_encode($arr, JSON_HEX_QUOT);

Then, in my view file :

<div class="card-content">
        {{ $data }}
</div>

<div id="chartPingListExpand" class="ct-chart"></div>

<script type="text/javascript">
    $(document).ready(function() {
        app.initChartPingListExpand({{ html_entity_decode($data) }}, {{ $maxping }});
    });
</script>

Here is the thing : My {{ $data }} shows correctly my json string

{"ping":[4,30],"doc":["2018-03-23 09:06:53","2018-03-23 01:04:23"]}

But Javascript doesn't like it :

Uncaught SyntaxError: Invalid or unexpected token

at this line

app.initChartPingListExpand({{ html_entity_decode($data) }}, {{ $maxping }});

And I think it's because HTML is translating quotes by &quot ; I've tried many ways to tell the html not to translate those quotes but it does not work, anybody has any idea ?

Maybe I can pass data to my Javascript function or any other way?

Answer 1

Your $data is already a javascript object, you don't need to decode it

You can try if you put var obj = {{ $data }}; console.log(JSON.stringify(obj)) var obj = {{ $data }}; console.log(JSON.stringify(obj))

Answer 2

You should use JSON.stringify which converts a JavaScript value to a JSON string

var data = JSON.stringify(jsonData);

Answer 3

Note that Blade will try to protect you and will escape all unsafe characters. use

{!! $data !!} 

to avoid that
