Hi,
I want to register a JavaScript, where I have to dynamical add parameters. I am using the following code:
In the console I get the following error:
SyntaxError: expected expression, got ‘<’
Looking at the source code of the web page I found, the the script was added in between another script:
Can anybody help me with this issue?
Cheers,
Torsten
Hi Torsten,
It looks like the first argument if $id looks like string so when you call the js function argument just use quotes.
$java = '<script type="text/javascript">
drawmap("' . $id . '", ' . $lat . ', '.$lon . ');
</script>';
As well when you ask some queries please do share the full error message and snippet.!! So that the community members can help you faster with good understanding.
Thank you very much. I added the quotes, but this did not fix the problem.
Here is a liitle bit more of my view.php
<?php
use yii\helpers\Html;
use yii\widgets\DetailView;
use kartik\tabs\TabsX;
use kartik\icons\FontAwesomeAsset;
/* @var $this yii\web\View */
/* @var $model frontend\models\EpiMain */
FontAwesomeAsset::register($this);
$this->title = $model->id;
$this->params['breadcrumbs'][] = ['label' => 'Epichloe Database', 'url' => ['index']];
$this->params['breadcrumbs'][] = $this->title;
$id = $model->id;
$lat = $model->latitude_dec;
$lat = strval($lat);
$lon = $model->longitude_dec;
$lon = strval($lon);
$java = '<script type="text/javascript">
drawmap("' .$id. '", ' .$lat. ', ' .$lon. ');
</script>;';
$this->registerJs($java);
\yii\web\YiiAsset::register($this);
The error messege in the console is just what I have written in my first post:
It points to the index file, where the script is still in the wrong place:
<script src="http://www.openstreetmap.org/openlayers/OpenStreetMap.js"></script>
<script src="/js/tom.js"></script>
<script src="/js/cdata_script.js"></script>
<script>jQuery(function ($) {
<script type="text/javascript">
drawmap("JKI-0013", 51.889151, 10.58899);
</script>;
jQuery&&jQuery.pjax&&(jQuery.pjax.defaults.maxCacheLength=0);
jQuery("#w6-container").tabsX(tabsX_00000000);
});</script></body>
</html>I found the problem.
registerJs is adding the <script> and </script> automatically.
The code has to be just this:
$java = ‘drawmap("’ .$jki_id. '", ’ .$lat. ', ’ .$lon. ‘);’;
$this->registerJs($java);
Cheers,
Torsten
