如何从列表框项目获取文本？

Question

当我尝试从JavaScript中的列表框项目中获取文本时，它始终返回未定义状态。

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

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

如何获取文本？

编辑：更多的信息：

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); 
    } 
}
