Questione.target.value, switch-case operators Pin

Hey guys,

I am finishing up a project. I am getting some errors that I need help with. I posted the questions as comments within the code. Thanks !

// Declares the buttonClick(e) function
function buttonClick(e) {
	
	
	// Declares variables calcValue, calcDecimal and buttonValues
	var calcValue = document.getElementById("calcWindow").value;
	var calcDecimal = document.getElementById("decimals").value;
	var buttonValue = e.target.value; // This is giving me an error saying it is undefined
	
	// Begins a switch-case structure to assign events to each button pressed
	switch(buttonValue) {
		case "del":
		calcValue = "";
		break;
		case "bksp":
		calcValue = eraseChar(calcValue);
		break;
		case "enter":
		calcValue = " = " + evalEq(calcValue, calcDecimal) + "\n";
		break;
		case "prev":
		calcValue =  + lastEq(calcValue) ; // I was told I need "operators" here?
		calcValue = calcValue + buttonValue;
		break;
	}

document.getElementById("calcWindow").value = calcValue;
document.getElementById("calcWindow").focus();

}


EDIT

The directions for the buttonValue are:

Quote:
Each calculator button has a value attribute that defines what should be done with that button. Declare the buttonvalue attribute equal to the value attribute of the event object target.
