Im fetching Product Attributes from Woocommerce, and echo them out in a script tag as variable to use with javascript in frontend. This might be a bad practice, feel free to enlighten me.
Example:
Product Attributes:
Total height: 43m
Total length: 55m
PHP queries "Total-height" as Attribute Name and "43m" as Attribute Value.
PHP replaces empty space with "-".
I can't define a javascript var with "-" in var name.
Example: var Total-height = "43m";
How could I fix this issue? Here is my code. Thanks in advance.
function product_attribute_dimensions(){
global $product;
foreach ($product->get_attributes() as $taxonomy => $attribute_obj ) {
// Get the attribute label
$attribute_label_name = wc_attribute_label($taxonomy);
$value = $product->get_attribute($taxonomy);
if ($value) {
$label = get_taxonomy($taxonomy)->labels->singular_name;
$profile_one = $value;
echo '<script>' . $attribute_label_name . ' = "' . $value . '";
</script>';
}
}

As I understand the generated string in the variable "$attribute_label_name" is the problem? Take a look at https://www.php.net/manual/de/function.str-replace.php
With this native PHP function you can search for a character (eg."-") and replace with something else (eg. "_")
echo '<script>' . str_replace("-", "_", $attribute_label_name) . ' = "' . $value . '";
But as you said, this might not be the best approach. I personally would add this kind of information into a "data-X" HTML attribute in some HTML element and would extract this in my JS. Similar to this:
<div id="some_element" data-total-height="<?= $value ?>"></div>
You could Query something like this with jQuery $("#some_element").attr("data-total-height")

try using window["variable_name"]
do this:
echo '<script>window["' . $attrname . '"]=' . $attrval
then in your js:
let this_var = window[attrname]
