Question

I have two three text boxes.

<input type="text" name="test" value="100" />
<input type="text" name="test" value="250" />

<input type="text" name="totalList" value="" />

What I would like to happen is for the totalList textbox to have all the values of the textboxes before seperated by a comma, so its value would be 100, 250. The reason it is in an array is because I am going to be extracting from a database and I do not know how many items there will be, I just know they will all have a price.

Thanks in advance guys.

Use the array.join method.

var elements = document.getElementsByName("test");
var values = new Array();
for(var i = 0; i < elements.length; i++) 
    values.push(elements[i].value);

document.getElementsByName("totalList")[0].value = values.join();
