I have a difficulty with my javascript

Question

I have been making a simple program and when I run the function "convert()" it does not do anything. It is definitely a problem with the var data line because I have tried using // to make it a comment and it works. Please help me have this work. Here is my javascript code for convert():

    function convert(){
            var data = document.getElementById("inputArea").split(":");
            for(var i=0; i<data.length; i++) { data[i] = +data[i]; }
            document.write("It works!");
    }

Answer 1

You need to take the value of the input element and not the input itself.
the right code :

function convert(){
        var data = document.getElementById("inputArea").value.split(":");
        for(var i=0; i<data.length; i++) { data[i] = +data[i]; }
        document.write("It works!");
}
