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>

    How can you enter multiple items through single text box?? Commented Dec 9, 2015 at 13:54
  • I have the same doubt. If you want to do it with only one textarea or textbox, first you need to define which is your word separator, it can be a comma or just spaces (not recommended). Commented Dec 9, 2015 at 14:00

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>

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(" - ");
}
