Is this proper JS for this J-Query expanding textArea? Is 'this' the same as event.target in JS also?

With these it helps Reset the height before Using scrollHeight to expand/shrink the textarea correctly. Math.min() can be used to set a limit on the textarea's height.
Code:
code :
var textarea = document.getElementById("textarea");
var heightLimit = 200; /* Maximum height: 200px */

textarea.oninput = function() {
  textarea.style.height = ""; /* Reset the height*/
  textarea.style.height = Math.min(textarea.scrollHeight, heightLimit) + "px";
};

This might help you There's no way to cancel the expansion completely. However, you can use the conditional assignment based on the value of $(MAKECMDGOALS):
code :
thisexpands = $(if $(filter target1,$(MAKECMDGOALS)),$(warning Expanded!))

.PHONY: target1
target1: $(thisexpands)
    @echo Target 1

.PHONY: target2
target2:
    @echo Target 2
