javascript convert object to string

Question

I have some form with several values depending which is selected

<form action="#">
    <select id="tropa1" name="tropa1">
        <option value="rec_b_unit">Case1</option>
        ....
        <option value="rec_z_unit">Case20</option>
    </select>
    <input id="go" type="button">
</form>

Now script

$(document).ready(function() {

    $("#go").click(function() {

        // Obtener la referencia a las listas
        var lista1 = eval(document.getElementById("tropa1"));
        // Obtener el valor de la opción seleccionada
        var valort1 = eval(lista1.options[lista1.selectedIndex].value);
        var cadena = String(valort1);
        console.log("PHP: " + String(valort1));
        if (cadena.indexOf('z') != -1) {
            // value selected in options does not contain 'z'
            console.log("DOES NOT CONTAIN Z");
            console.log(cadena);

            confront(nu1, valort1, nu2, valort2)

        } else {
            //// value selected in options contains 'z'
            console.log("CONTAINS Z");
            console.log(cadena);
        }
    })

});

I tried to make this, but console return : [object Object] and not show string. even using String() function or eval() to convert object to a string

Why do you think `eval` would convert an object to a string? — Bergi, Apr 22 '15 at 12:06
You don't need all those `eval` statements. What are you trying to achieve here? — CodingIntrigue, Apr 22 '15 at 12:06
Since you're using JQuery, you may want to investigate JQuery's `serialize` method. https://api.jquery.com/serialize/ — xDaevax, Apr 22 '15 at 12:07
var yourObject = {"name" : "stack","id":"123"}; JSON.stringify(yourObject); @Raphael — Arepalli Praveenkumar, Apr 22 '15 at 12:19

If you want to display the content of your object in the console, you can use console.dir().

If you want a function which returns a string you can override the toString() function.
