javascript - 过滤结果是一个对象数组，就像使用 lodash 的operator(%oil%)

Question

这个问题已经有答案了:

JS: Filter object array for partial matches (3 个回答)

已关闭 5 年前。

我想根据用户的输入更改来过滤对象数组，并使用 LODASH ( https://lodash.com/ ) 创建一个新的匹配对象数组数组。

let listing = [{title: "Courier/Logistics", id: 1, totalWorkers: 1058, openPositions: 0, omani: 99.72},
{title: "Information Technology", id: 1, totalWorkers: 2, openPositions: 1, omani: 50},
{title: "Oil & Gas", id: 1, totalWorkers: 98, openPositions: 6, omani: 91.84}];

我尝试过lodash _.filter但这会过滤精确的单词和精确的大小写，然后返回单个搜索值。

const filtered = _.filter(listing, function(o) {
        return o.title === "oi";
      });
      console.log(filtered);

我想得到结果，就像我们在 mysql 中所做的那样:

WHERE title like %oi% 

它给出包含该输入的匹配值。

谢谢

查看片段，用于 lowerCase 来匹配所有大写和小写的字符串，在您的示例中，您的字符串“Oil & Gas”采用驼峰式大小写，当您尝试匹配该字符串时，它始终会导致空白数组。

let listing = [{title: "Courier/Logistics", id: 1, totalWorkers: 1058, openPositions: 0, omani: 99.72},
{title: "Information Technology", id: 1, totalWorkers: 2, openPositions: 1, omani: 50},
{title: "Oil & Gas", id: 1, totalWorkers: 98, openPositions: 6, omani: 91.84}];
const filtered = _.filter(listing, function(o) {
  return o.title.toLowerCase().indexOf("oi") > -1;
});
console.log(filtered);
