我正在尝试创建一个函数，根据搜索结果给出一个匹配的百分比，例如，如果搜索匹配我的数组中的2/9个字段，那么我将获得该匹配的适当百分比，如果它匹配a从一个9/9的数组中收缩它将显示100％。
以下是代码：

请注意我是JS的新手，但我想在我的任务中做得很好，这是我唯一缺少的功能（这不是必需的，但我想学习如何去做）
答案 0 :(得分：0)
一种简单的方法是在每个条件下以if分解搜索的大if块。对于每个条件，增加一个表示匹配数的变量（matches）。如果matches＆gt;合同很好。 0，百分比为100 * matches / total_number_of_conditions。
这样的事情：
...
var matches = 0;
var total_number_of_conditions = 9;
if (brandCheck == contract[p].brand) matches += 1;
if (model.value == contract[p].model) matches += 1;
if (networkCheck == contract[p].network) matches += 1;
if (minutes >= contract[p].minutes) matches += 1;
if (e.value == contract[p].texts) matches += 1;
if (f.value == contract[p].data) matches += 1;
if (g.value == contract[p].upcost) matches += 1;
if (h.value == contract[p].monthlycost) matches += 1;
if (i.value == contract[p].length) matches += 1;
if (matches > 0) {
var percentage_matched = 100 * (matches / total_number_of_conditions);
document.write(contract[p].brand +
" " + contract[p].model +
" " + contract[p].network +
" " + contract[p].minutes +
" " + contract[p].texts +
" " + contract[p].data +
" " + contract[p].upcost +
" " + contract[p].monthlycost +
" " + contract[p].length +
" " + percentage_matched + "% </br>");
}
...
当然，还有许多其他更易配置和复杂的解决方案可用于分离和应用条件，例如“匹配器”对象列表，每个条件对应一个等等。
