将液体分配给javascript变量

Question

var first = 'one',
    second = 'two.png';
    image = first + second;
console.log('js image: ' + image);
image = '{{ image | asset_url }}';
console.log('liquid image: ' + image);

Produces in the console:

js image: onetwo.png
liquid image: 

I cannot get the code to output the code from the liquid filter. I have tried using {% raw %} and looked at a few SO questions ( Shopify: Using variables from {% schema %} in Javascript , Using javascript variables in Shopify liquid , Using asset_url within a .js.liquid file ) to no avail.

What am I doing wrong here? I am expecting to get:

liquid image: onetwo.png?123456789

Even removing asset_url :

image = '{{ image }}';

Still produces:

liquid image:

Answer 1

Retrieve the variable in the following way:

image = {{ 'image' | asset_url }};

//console log
js image: image.png
liquid image: image.png

Answer 2

After chatting with @Subhrajyoti Das there is a hacky way of doing it.

Create the full string with dummy text where the actual filename is:

assetString = '{{ 'filename' | asset_url }}'

This produces:

cdn.shopify.com/s/files/0/0000/0000/0000/t/00/assets/filename?0000000000

Then use string replacement to replace 'filename' with the asset variable:

image = assetString.replace("filename", image);
