How to load a <script> src = " " </script> into my mirror?

[nbrenn]

@morozgrafix Everything is working very well so far!

I am updating my “Sum” daily, but I would like to be able to show the previous day’s sum. Could I store the value of the sum at 11:59pm, each evening, and then display that value in addition to the current day’s sum?

Additionally, how could I modify the line of code:

this.sum = lines.reduce((a, b) => a + b, 0);

to allow for me to sum across multiple columns? So, if my .csv has 3 columns, I’d like the sum total of them.

@nbrenn sorry swamped at work today. That line just takes all of the values from each line and adds them up. It will not work for multiple columns and true csv files. You would need to resort to logic that we had initially in JSfiddle. If I have time I will look into this later today.

@morozgrafix I think I can work around this by changing the SQL query (that generates my .csv) to include just one column. Then I can implement it as a new module, placed above the current one.

Does anyone know of the best documentation for adding an image/graphic into a mirror module?

For my example here, Mirror Datafeed and Sum Module, I am summing over the values in a column in a .csv and then outputting it.

I would like to show an image based on what that value is. As a crude example, if the sum is greater than 50, output a frown. If it is less than 50, show a smiling face. What’s the best documentation for putting in graphics that will work on the mirror?

@nbrenn I’m sure there are many ways but here’s one … :laughing:

I borrowed this from strawberrys modules…

var awayLogo = document.createElement("span");
               var awayIcon = document.createElement("img");
               awayIcon.src = this.file("icons/" + game.awayTeam + ".png");
               awayLogo.appendChild(awayIcon);
               large.appendChild(awayLogo);

he’s getting the name from parsing xml and the away team name is for example ‘bal’… so his png in his icon folder is named ‘bal.png’ and here he’s calling it to show… that’s one way :)

You can also look at morozgrafix’s MMM-Horoscope to see another … hope it helps!

@cowboysdude Thanks for the example!

Is there a specific styling that needs to be used for the images? For example, I would need the image to have the typical white/greyish hue to it.

@nbrenn I believe you can do it with a classid…

var gameTemp = document.createElement("div");
               gameTemp.classList.add("gametemp");

Then add it your css file:

.MMM-NFLweather .gametemp {
    color: #10B1C8;
}

@cowboysdude this will not work for images

therefore you have to add a filter -webkit-filter: grayscale(100%);

@strawberry-3.141 Yeap you’re right… he wanted greyscale… ok got it!
