Hi guys, i have the problem.

I need insert the meta tag facebook script on my website, so, need inside with dynamic function.

i used the begin script.

<dmx-value id="mypixels" dmx-bind:value="sc_checkfbpixels.data.fbpixels[0].pixelID"></dmx-value>

    <!-- Meta Pixel Code -->

    <script>

        function myFunction() {

        var pixels = dmx.parse('mypixels.value');

        console.log(pixels);

        }

I need help, thanks for much.

Try:

var pixels = dmx.parse('content.mypixels.value');

It worked without the “content”…

What I’m trying to do is:

Insert a script made in the header. Pulling this script from the database. I tried with dmx-text and it didn’t work because it messed up the script by inserting
. I tried with dmx-value and it didn’t work.

Do you have any tips?

Pulling this script from the database.

This is quite a bad practice. But if you insist you have JS eval() function.

I understand, as I commented earlier, do you know how to insert a complete script through dmx?

[JonL]

dmx is just the namespace for App Connect. What do you mean with

@bsg

do you know how to insert a complete script through dmx?

What do you have in your database exactly? A fb pixel number that you need to inject into a script or actual js code?

[bsg]

I have the complete script.

<script> facbook pixel </script>

I want to inject it into the header dynamically. ex, I pull all the scripts that are in the selected bank.

If you are using nodejs you can inject the code at server parsing time by using EJS templating.

How to make this?

Using Server Connect Data for Server Side Rendering in NodeJS

You already know how to setup your pages to use Sever Side Rendering with NodeJS. In this tutorial we will show you how to use Server Connect data in your page meta tags, such as page title and description. Overview In our example we will show you a dynamic product details page, where the product title will be displayed as page title and product description will be added to the description meta tag. We have a page listing our products: [Screenshot_3] When the details button is clicked, th…

How to make a <script> with dynamic "src" parameter?

This is a simpler example I could find on how to build your JS function which would inject the script tag. There are other sample codes on the page, which you can try as well. Once you have created this function on page or in your custom JS file, call that function in page flow. Hope this helps.

This one is not very useful, it has to be something that imports the complete script from the database.

I tried too but it didn’t work. Unfortunately I have to insert with a dmx, I just don’t know which one. Because the code must be loaded on the page.

Then import the complete script. There is no limitation on what you inject via EJS as it’s added before the webpage is rendered in the browser.
