如何从列表框项中获取文本？

Question

当我尝试从javascript中的Listbox项获取文本时，它总是返回undefined。

winkeloptie.value = winkels[i][0]; 
winkeloptie.text = (winkels[i][0]);

alert(winkeloptie.value) ///This returns the value very nicely
alert(winkeloptie.text) //Returns undefined

我如何获取文字？

function addWinkels(){
    var winkellijst = document.getElementById('winkel');
    for (var i = 0;i < winkels.length;i++){
        var winkeloptie = document.createElement("Option");
        winkeloptie.text = (winkels[i][0]);
        winkeloptie.title = (winkels[i][1]);
        winkeloptie.value = winkels[i][0]; 
        winkellijst.options.add(winkeloptie); 
    }
}
