Help with updateDom

MMRIZE

but what I am trying to avoid is that when I start the mirror, all modules stay active on the 1st screen instead of hiding the modules I don’t want active on the 1st screen. I am using MMM-pages for this. Because there is a delay in the data being returned it causes this issue.

Hmmm. I think hiddenOnStartup option of the module configuration would be what you really consider.

https://forum.magicmirror.builders/uid/6639 also. you don’t HAVE to show any content. you can return an empty div and mm is happy

you should also keep track of your hidden state (suspend/resume) and not call uodateDom while hidden… so u won’t generate any content while pages has u hidden

@sdetweil The biggest issue is that I need to set arrows based on data being returned. I.e. Arrow will go up depending on the data or it points down based on the data. That is where I am stuck. How do I set those back into the wrapper based on the data.

generateSolarLine: function() {
    var ppvData = parseInt(this.growattData[0].ppv1) + parseInt(this.growattData[0].ppv2);
    solarLabel.innerHTML =  `Solar: ${ppvData}W`;
    if(ppvData > 0) {
        solarLine.classList.add("active");

        const solarArrowOut = document.createElement("i");
        solarArrowOut.classList.add("arrow", "down", "active");
        solarLine.appendChild(solarArrowOut);
    } else {
        solarLine.classList.add("dimmed");
    }
    return solarLine;
},

Bases on the value of ppvData I am setting which way the arrow points etc. Doing all the work in the getDom gives issues

@mumblebaj

save solarArrowOut as a module instance variable and redo it’s attributes when u need to.
instead of creating it fresh ever time

this means all the stuff around it should be stable too…

@sdetweil Thanks Sam. Managed to resolve this. Everything works fine now and plays well with the other modules.
