Javascript/html : Two input range field balance scale

Question

如何使这两个输入范围字段平衡到最大 100，当我移动第一个输入字段范围时，第二个输入字段范围也应该调整，反之亦然。我的意思是它应该像天平一样成正比。

这是我的代码 https://jsfiddle.net/jsm4s2oz/1/

//First input range

<output name="judge_rangeOutput" id="judge_rangeOutput">75</output>
<input type="range"  name="judge_range" id="judge_range" min="0" max="100" value="75" oninput="judge_rangeOutput.value = judge_range.value"><br/>


//Second input range
<output name="preJudge_rangeOutput" id="preJudge_rangeOutput">25</output>
<input type="range" name="prejudges_range" id="prejudges_range" min="0" max="100" value="25" oninput="preJudge_rangeOutput.value = prejudges_range.value ">

在你的input处理程序，除了更改 <output>同一 slider 的字段，还更改另一个 slider 和另一个的值 <output>至 100 - this.value .

$("#judge_range").on("input", function() {
  $("#judge_rangeOutput").val(this.value);
  $("#prejudges_range").val(100 - this.value);
  $("#preJudge_rangeOutput").val(100 - this.value);
});
$("#prejudges_range").on("input", function() {
  $("#preJudge_rangeOutput").val(this.value);
  $("#judge_range").val(100 - this.value);
  $("#judge_rangeOutput").val(100 - this.value);
});

First input range
<output name="judge_rangeOutput" id="judge_rangeOutput">75</output>
<input type="range" name="judge_range" id="judge_range" min="0" max="100" value="75">
<br/>Second input range
<output name="preJudge_rangeOutput" id="preJudge_rangeOutput">25</output>
<input type="range" name="prejudges_range" id="prejudges_range" min="0" max="100" value="25">
