Google 如果字符串中的任何单词与另一个字符串匹配，Apps 脚本会获取索引？

Question

我有一长串从 sheet 范围中获得的角色，这些范围存储为数组中的字符串，举个例子，数组看起来像这样：

arr1 = ["football manager","hockey coach", "fb player","fb coach","footballer"];

我还有另一个数组，其中有一小部分标签

arr2 = ["football","fb", "footballer","hockey","rugby"];

我正在尝试将第一个数组的角色与第二个数组中的标签相匹配。

我一直在尝试通过循环获取匹配行的索引来做到这一点：

for(let i in arr1){
arr2.findIndex(s => s.indexOf(arr1[i]) >= 0);
}

但这只适用于“footballer”，因为它是完全匹配，我需要对所有部分匹配进行分类。

Answer 1

使用以下函数查找与 arr1.

中的值匹配的标签索引（来自 arr2 数组）

详细解释请关注代码注释。

function matchTagIndexes()
{
  // TODO replace with your values
  arr1 = ["football manager","hockey coach", "fb player","fb coach","footballer"];

  // TODO replace with your tags
  arr2 = ["football","fb", "footballer","hockey","rugby"];

  // for all tags create regex objects
  // regex searches for any match that have `tag` surrounded with word (\b) boundaries 
  // see https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Regular_Expressions/Cheatsheet#boundary-type_assertions
  const arr2Regexes = arr2.map(tag => new RegExp(`\b${tag}\b`, 'i'));

  // loop arr1 values as val
  arr1.map(val => 
    // for each arr2 regex match val
    arr2Regexes.forEach((regex, i) => 
      // if it is matched, log value from arr1 array, matched tag name and tag's index in arr2 array
      val.match(regex) && console.log(`"${val}" matches tag "${arr2[i]}" which has index ${i}`)
    )
  );
}

结果：

time	status	message
8:46:35 PM	Notice	Execution started
8:46:35 PM	Info	"football manager" matches tag "football" which has index 0
8:46:35 PM	Info	"hockey coach" matches tag "hockey" which has index 3
8:46:35 PM	Info	"fb player" matches tag "fb" which has index 1
8:46:35 PM	Info	"fb coach" matches tag "fb" which has index 1
8:46:35 PM	Info	"footballer" matches tag "footballer" which has index 2
8:46:36 PM	Notice	Execution completed

Answer 2

我怀疑某些文本可能有多个标签 (arr1)。这是获取每个文本的标签（索引）数组的解决方案：

var texts = ['football manager','hockey coach', 'fb player','fb coach','footballer', 'none'];
var tags = ['football','fb', 'footballer','hockey','rugby', 'coach'];

// get all tags for all the texts
var list = [];
for (let tag of tags) {
    var mask = RegExp('\b' + tag + '\b', 'i');
    for (let text of texts) {
        if (text.match(mask))
            list.push( {'text': text, 'tag': tag, 'tag_index': tags.indexOf(tag)} );
    }
}
console.log(list);

// group tags for the same texts
var text_and_tags = {};
for (let element of list) {
    try { text_and_tags[element.text].push(element.tag_index) }
    catch(e) { text_and_tags[element.text] = [element.tag_index] }
}
console.log(text_and_tags);

它将为您获取对象 text_and_tags，如下所示：

{
  'football manager': [ 0 ],
  'fb player': [ 1 ],
  'fb coach': [ 1, 5 ],
  'footballer': [ 2 ],
  'hockey coach': [ 3, 5 ]
}
