To use reserved Marketo syntax (like ${variable}) in Landing Pages, tap {{my.tokens}}

Marketo’s ${variable} syntax conflicts with other languages using the same dollar-single-curly-quote syntax, like good ol’ JavaScript.

 

So if you try to use a JS template literal in the LP Editor...

<script> let a = `Report ID ${report} for ${this.name}`; </script>

 

... Marketo naturally thinks you’re referring to missing variables and throws an error:

 

Officially, there’s no alternate syntax in Marketo (and there’s definitely no way to change the delimiter in JS). But the workaround is easy. Create a global Text token {{my.d}} just containing the single character $:

 

 

(Why {{my.d}}? Just copying Velocity’s $esc.d, which also escapes the dollar sign. You could use another name if you want, but this should be easy to remember.)

 

Use that token to escape the $ sign:

<script> let a = `Report ID {{my.d}}{report} for {{my.d}}{this.name}`; </script>

 

Marketo will render this as:

<script> let a = `Report ID ${report} for ${this.name}`; </script>

 

Presto!

    That’s the expected behavior when you escape the variable syntax. As far as I can see you have no reason to use the method in this post. You want Marketo to use the standard ${variable} syntax, not ignore it. This method is for people who need to use ${variable} for another purpose and don’t want Marketo interfering.

    <meta class="mktoBoolean" id="livewebinar2" mktoName="Live webinar?" default="true" true_value="LIVE WEBINAR" true_value_name="Live" false_value="ON-DEMAND WEBINAR" false_value_name="On-demand">

    <script>


    if ("{{my.q}}{livewebinar2}" == "LIVE WEBINAR") {
    MktoForms2.whenReady(function (form){
    form.onSuccess(function(vals, page){
    form.getFormElem().hide();
    var confirm = document.getElementById('confirmation');
    confirm.style.display = 'inline-block';
    confirm.setAttribute('aria-hidden', false);
    return false;
    });
    });
    }
    </script>

     

    When I publish my page and view source, the variable doesn't show the value. Instead, it shows: if ("${livewebinar2}" == "LIVE WEBINAR"). So I was assuming it was a problem with the variable not posting the value?

    You’d have to show your code. Not sure what you mean by ${{variable}} as that’s no Marketo or JS syntax.

    Hi - I couldn't get this to work. My landing page was still showing ${{variable}} in the Javascript, rather than the value. Any advice on how to make it work as part of an 'if' statement?
