js 变量判断?

Question

拖动from marker 可以正常移动 ,但是拖动to 只能固定一个点位
$("#range").on("change", function () {

     
            var $this = $(this),
            from = $this.data("from");
            to = $this.data("to");
           
                var fromData = fromToDis(json.data,to);
                computeOffsetCommon(fromData,1,"起点");
       
                var toData = fromToDis(json.data,from);
                computeOffsetCommon(toData,2,"末点");
      
    });

Answer 1

建议把详细代码贴一下。。
比如：computeOffsetCommon 的具体实现
