Question

嘿，我有这个数组

[
 0: "Migration, MD"
 1: "Lution, MD"
 2: "Mover, MD"
 3: "Dee"
 4: "Prov10A"
]

如何获取其中包含单词MD的值像是有医学博士，应该给我这样的东西

[
 0: "Migration, MD"
 1: "Lution, MD"
 2: "Mover, MD"
]

我如何用lodash做到这一点？谢谢

Answer 1

使用filter和includes：

const arr = ["Migration, MD", "Lution, MD", "Mover, MD", "Dee", "Prov10A"];
const res = arr.filter(e => e.includes("MD"));
console.log(res);

.as-console-wrapper { max-height: 100% !important; top: auto; }

Answer 2

您可以使用filter，toLowerCase和includes。 filter将返回一个新数组，toLowerCase将转换该元素的大小写，因此将同时考虑md，MD。

let k = ["Migration", "MD", "Lution, MD", "Mover, MD", "Dee", "Prov10A"].filter(function(item) {

  return item.toLowerCase().includes('md')
});
console.log(k)

Answer 3

您可以尝试过滤功能

    const  arr = [
     "Migration, MD", "Lution, MD" , "Mover, MD", "Dee", "Prov10A"
    ]

    const out  = arr.filter(e => e.includes('MD'))
    console.log(out)

Answer 4

如果您只想找到一个带有“ MD”的单词，或者只找到第一个单词，则可以使用Java脚本查找方法，如果您想要一个具有“ MD”的单词数组，则可以使用过滤器方法。

 const  arr = [
     "Migration, MD", "Lution, MD" , "Mover, MD", "Dee", "Prov10A"
    ]
    const result = arr.find(word=>word.includes("MD"));
    console.log(result);
// to get array of words with MD simply change .find as .filter in above code.
