javascript - javascript/jquery 简单搜索引擎 - 实现一个简单的搜索引擎，数据存储在数组中

Question

问题已编辑！我已将所有产品名称以对象格式存储在一个数组中。我也有一个输入[type=text]。我需要一个简单的代码来搜索这个数组。SQL 命令类似于：（SELECT name FROM tbl_product WHERE name LIKE %txt%）。但是我在前端实现这个并且与后端没有连接！

<input type="text" id="mytxt" />

<script>
// [{ in_ordered_id : "product name"}, ...]
var products_name = [{ 8 : "product ninety two"}, {21 : "product two"}, {35 : "product nine"} , ....];
$("#mytxt").keyup(function(){
     var txt = $("#mytxt").val();
     var results = start_search(txt); // `results` must be array of ids e.g. [35, 98]

});

function start_search(text){
     /// I don't know what to write here
}
</script>

string.includes可能有帮助

products_name = ["product one", "product two"];


$("#mytxt").keyup(function() {
  var txt = $("#mytxt").val();
  var results = start_search(txt);
  console.log(results);
});

function start_search(text) {
  return products_name.filter(pr => pr.includes(text))
}

<input type="text" id="mytxt">

- 编辑

const products_name = [{
  8: "product ninety two"
}, {
  21: "product two"
}, {
  35: "product nine"
}]


$("#mytxt").keyup(function() {
  var txt = $("#mytxt").val();
  var results = start_search(txt);
  console.log(results);
});

function start_search(text) {
  return products_name.filter(pr => Object.values(pr)[0].includes(text)).map(pr => Number(Object.keys(pr)[0]))
}

<input type="text" id="mytxt">
