获取跨度的值，并将该值添加到输入字段

Question

我有一个范围滑块，并且我想要将数据滑块属性添加到输入字段中，因为它数字增加或获得跨度值添加输入字段：

<div class="small-10 medium-11 columns"> 
    <div class="range-slider" data-options="display_selector: #sliderOutput3;" data-slider="35"> 
     <span class="range-slider-handle" tabindex="0" role="slider" style="transform: translateX(287.75px);"></span> 
     <span class="range-slider-active-segment" style="width: 35%;"></span> 
    </div> 
</div> 
<div class="small-2 medium-1 columns"> 
    <span id="sliderOutput3">35</span> 
</div> 
<input id="donationamount" type="text" value="50" name="donationamount"> 

我试过，但它并没有设定值：

$('#sliderOutput3').on('change', function() { 
    var tc = $('#sliderOutput3').text(); 
    $('#donationamount').val(tc); 
});

HTML：

<div class="small-10 medium-11 columns"> 
    <div class="range-slider" data-options="display_selector: #sliderOutput3;" data-slider="35"> 
     <span class="range-slider-handle" tabindex="0" role="slider" style="transform: translateX(287.75px);"></span> 
     <span class="range-slider-active-segment" style="width: 35%;"></span> 
    </div> 
</div> 


<div class="small-2 medium-1 columns"> 
    <span id="sliderOutput3">35</span> 
</div> 
<input id="donationamount" type="text" value="50" name="donationamount"> 
<br> 
<input id="donationamount2" type="text" value="50" name="donationamount2"> 

的jQuery：

$('#sliderOutput3').ready(function() { 
    //example 1 
     var tc = $('#sliderOutput3').text(); 
     $('#donationamount').val(tc); 

    //example 2 
     var dataSlider = $(".range-slider").attr("data-slider"); 
     $('#donationamount2').val(dataSlider); 
}); 

EXAMPLE

可以吗？
