JavaScript通过多个字符串过滤数组？
要按多个字符串过滤数组，请将for循环与一起使用indexOf()。以下是代码-
示例
var details = [
'My first Name is John and last Name is Smith',
'My first Name is John and last Name is Doe',
'Student first Name is John and last Name is Taylor'
];
var isPresent;
var records = [];
var matchWords = ['John', 'Doe'];
for (var index = 0; index < details.length; index++){
isPresent = true;
for (var outer = 0; outer< matchWords.length; outer++) {
if (details[index].indexOf(matchWords[outer]) === -1) {
isPresent = false;
break;
}
}
if (isPresent){
records.push(details[index]);
}
}
console.log(records)要运行上述程序，您需要使用以下命令-
node fileName.js.
在这里，我的文件名为demo151.js。
输出结果
这将产生以下输出-
PS C:\Users\Amit\JavaScript-code> node demo151.js [ 'My first Name is John and last Name is Doe'
