Javascript stack

[DDH]

Hi,

I am having troubles creating java script stack. Basically I need to store user input from text box into stack and display how the stack grows in text box at the time of storing the values, if that makes sense. Can anyone give me a hand. This is what I got so far, but instead of stacking elements one over another it adds em one below another:

function userInput(e){
 
 var x = document.getElementById("TextBox1");
 
 if(e.which == 13)
 
 if (document.getElementById("input").value > "") {
 
 backStack.push(document.getElementById("input").value);
 
 x.innerHTML = backStack.join('<br/>'); 
 
 document.getElementById("input").value = "";
 
    }
 }

If you want the most recently added entry at the top instead of at the bottom then replace push() with unshift()

Thanks! That worked, but I need to do it with LIFO so I think I must use push() and pop() instead of shift() and unshift() . Thank you again for the repsonse

LIFO can use either push() and pop() or unshift() and shift() - which you use only affects which end of the array is which

FIFO can use either push() and shift() or unshift() and pop()
