我有一个包含信息阵列, 它基本上只是一个整数列表, 然后与这些整数相重叠的是每个整数的具体计算值。 这个数组的大小将取决于输入的值, 但不会超过 10 个条目 。
我想做一个下拉菜单, 让用户可以选择其中的一个整数, 然后向用户显示相应的计算结果。 我还需要一个特定值( 取决于计算结果) 才能默认地选择, 作为一种“ 最佳” 的答案 。
可能我需要展示的一件事:
Options in dropdown: 1 2 3
Coinciding options for display 23.536 36.577 40.164
自动选择的值为第二个条目( 取决于计算结果) 。 矩阵可能位于1- 10 项的任意位置 。
谢谢你的帮助!
问题解答者没有给出初始代码 : 以循环方式或循环方式通过数组循环, 为每个条目建立列表项( li ) 。 那么如果您想要处理计算客户端, 或者想构建一个机制, 通过对服务器的请求来接受此值并做出实物回应, 您就需要在 JS 中绑上 。 祝你好运!
