<apex:outputText> {!$Label[mylabel]} </apex:outputText>

What i wanted to do, in fact exist on lightning, here is the code :

 var labelSubStr = "task_mode_today";
 var labelReference = $A.getReference("$Label.c." + labelSubStr);
 cmp.set("v.tempLabelAttr", labelReference);
 var dynamicLabel = cmp.get("v.tempLabelAttr");

Here is the link to the doc : https://developer.salesforce.com/docs/atlas.en-us.lightning.meta/lightning/labels_dynamic.htm


As i'm using a visualforce page to contain my lightning component. I evaluated my labels dynamically in my vf controller using the following method like this :

 public string getLabel(object o){      
    Component.Apex.OutputText output = new Component.Apex.OutputText();
    output.expressions.value = '{!$Label.' + string.valueOf(o) + '}';
    return String.valueOf(output.value);

This method use the output.expressions.value variable which can only be used in a visualforce class controller.

I processed all my required labels via this method and return a map of those label as an object to my lightning component

  • For anyone looking at this in 2023 - this does not work any longer. Creating dynamic Apex components is restricted to actual Visualforce controllers now.

Doing this: https://developer.salesforce.com/docs/atlas.en-us.lightning.meta/lightning/labels_value_provider_platform.htm works for me.

Just try this: console.log($A.get("$Label.namespace.labelName"));

  • console.log($A.get("$Label.namespace.labelName")); doesn't work for me. Forget about the dynamic, the static one isn't working either :(

  • Even if you call an apex controller method that returns that label content doesn´t work for you?

I was able to find this on the Developer Pages.
