Can you use placeholders in javascript chunks?

This keeps giving me errors right after wherever I put the placeholder.

<script type="text/javascript">

var link = [[*shoplink]]

if(link != null) {
document.write("<a href="[[*shoplink]]">Buy Now</a>");
}else{
document.write("Call for pricing");
}

</script>

I would imagine that the javascript requires that value to be in quotes like any other string; ’[[*shoplink]]’

That stopped the error but the placeholder variable wasn’t passing through.

Is there an easier way to see if a placeholder is null in a chunk?

I decided to try it in PHP instead and it seems like I’m getting more progress like that using

[[shop-linkage]]

snippet in my chunk with the snippet containing

$shoplink = $modx->getPlaceholder('shoplink');

if ($shoplink != null){
echo "<a href='" . $shoplink . "'>Buy Now</a>";
}else{
echo "Call for pricing";
}

But the $shoplink variable is always coming back as null.

Well, [[*...]] is not a placeholder. [[+...]] is the tag for placeholders.

I think I may be using the wrong terminology. I was trying to access a template variable. I ended up having to pass the variable through the snippet such as [[!Snippet?phpvariable=[[*templatevariable]]]]

Think I finally found this solution in an old thread of yours.

Thanks for the help!
