How can I assign a URL string from a tag to a JavaScript variable?

[tobitobin]

Trying to get a url string from a tag, meta_Image:<url>, assign it to a javascript variable but returns undefined.

{% for tag in product.tags %}

{% if tag contains "meta_Image" %}

{% assign url = tag | split:"meta_Image:" | last %}

<script>

$(document).ready(function(){

var m_Image = {{ url }};

var imageContainer = $(".rondell-container");

imageContainer.css('background-image','{{m_Image}}');

console.log(m_Image);

console.log("success")

});

</script>

{% endif %}

{% endfor %}
