Chrome Won't Search data list by Label

我有以下输入框在我的网站，我想通过给定的标签给出建议，当选择的值传递给SQL数据库。

<input type="text" name="Search" size="45px" placeholder="&nbsp;Search student records." list="StudentList">
<datalist  id="StudentList">
    <option value="145" label="Jake">
</datalist>

我希望建议根据标签而不是按值显示，就像在Firefox中一样。

我该怎么做呢?

var studentList = document.getElementById('StudentList');
var selectedLabel = studentList.options[studentList.selectedIndex].getAttribute('label');

编辑:

html:

<input type="text" name="Search" size="45px" placeholder="&nbsp;Search student records." list="StudentList">
<datalist  id="StudentList">
    <option value="Jake" data-id="145">
</datalist>

js:

var search = document.getElementsByName('Search')[0];
var datalist = document.getElementById('StudentList')[0];
search.addEventListener('change', function(){
    var id;
    for(var i = 0; i < datalist.options.length; i++){
        if(datalist.options[i].value === this.value)
            id = datalist.options[i].getAttribute('data-id');
    }
    // Use id here to search
});
