@emrhssla said in How can I run console.log("text") when I click on an image?:

var elemimg = document.getElementById(“imgid”)
elemimg.addEventListener(“click”, () => {

because the getDom() function has not returned the new content to be added to the dom, you cannot search the dom to find it YET… cause its only in memory for your module…

i always want this routine to be called getDomContribution(), cause thats what it does. it gets this modules content contrubition to the single web page… on return, the MM runtime will then insert the content in the position the module is defined in.

but, you don’t need to search… you have it already

var image = document.createElement("img");
  //@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ adding this code @@@@@@@@@@@@@@@@@@@@@@@@@@@@
					image.id="imgid";
					image.addEventListener("click", () => {

@emrhssla also, on the module side, logging is Log.log() instead of console.log()
then u open the developers window, and select the console tab…

currently there is no mechanism to show both parts of a module in the same place
node_helper = console.log() - shows in terminal window
module.js = Log.log() - shows in developers window, console tab
