Creating array from multiple inputs

Question

I am trying to create an array where users enters multiple items into text box. All i can get my function to return is the first entry. Maybe i am approaching this wrong?

 function treez() { var treesArray = []; var ar = treesArray.push(document.getElementById("trees").value); var st = treesArray.toString(); document.getElementById("tresult").innerHTML = st; } 

 Enter 7 Trees <br> <textarea rows="5" cols="50" id="trees" name "trees"></textarea> <br> <br> <button type="button" class="processButton" onclick="treez()">submit</button> <br> <p id="tresult"> <p> 

Answer 1

Move treesArray out of the trees function.

With it being in there, its being recreated every call.

 var treesArray = []; function treez() { var ar = treesArray.push(document.getElementById("trees").value); var st = treesArray.toString(); document.getElementById("tresult").innerHTML = st; } 

 Enter 7 Trees <br> <textarea rows="5" cols="50" id="trees" name "trees"></textarea> <br> <br> <button type="button" class="processButton" onclick="treez()">submit</button> <br> <p id="tresult"> <p> 

Answer 2

You can do it like this, asking the user to separate each entry with a comma:

var treesArray = []
function treez() {
    var trees = document.getElementById("trees").value;
    treesArray = trees.split(",");
    document.getElementByID("tresult").innerHTML = treesArray + 
       "   " +  treesArray.join(" - ");
}
