javascript - JS数组中每个单词大写的方法

Question

我试图将一个简单的 JS 数组中的每个第一个字母大写， 代码在控制台日志中运行良好 - 但在输出中运行不正常

谢谢。

<select id="selectId">
<option value="hello">one</option>
<option value="hello">two</option>
<option value="hello">three</option>

var arr=[];
$("#selectId >option").each(function() {

   arr.push(this.text.substr(0,1).toUpperCase() + this.text.substr(1));

});
var i, len, text;
for (i = 0, len = arr.length, text = ""; i < len; i++) {

    console.log(arr[i]);
    $("#select").text(arr[i]);
}
