HTML5 type = range-显示标签 [英] HTML5 type=range - showing label

问题描述

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，我有一个范围控件<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.有办法吗?

Is there a way I can also set some label text for each steps in the HTML5 type=range control. Basically I have a range control <input type="range" step=1 min=0 max=4> and for each steps I want some label to be shown in the control. Is there a way to do this?

// 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()]);
    });

});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="range" id="rangeInput" name="rangeInput" step="1" min="1" max="4">
<label id="rangeText" />
