HTML5 type=range - 显示标签

Question

有没有一种方法可以为 HTML5 type=range 控件中的每个步骤设置一些标签文本。基本上我有一个范围控制 <input type="range" step=1 min=0 max=4>对于每个步骤，我都希望在控件中显示一些标签。有办法做到这一点吗？

我已经为你准备好了。

// define a lookup for what text should be displayed for each value in your range
var rangeValues =
{
    "1": "You've selected option 1!",
    "2": "...and now option 2!",
    "3": "...stackoverflow rocks for 3!",
    "4": "...and a custom label 4!"
};


$(function () {

    // on page load, set the text of the label based the value of the range
    $('#rangeText').text(rangeValues[$('#rangeInput').val()]);

    // setup an event handler to set the text when the range value is dragged (see event for input) or changed (see event for change)
    $('#rangeInput').on('input change', function () {
        $('#rangeText').text(rangeValues[$(this).val()]);
    });

});

<input type="range" id="rangeInput" name="rangeInput" step="1" min="1" max="4">
<label id="rangeText" />
