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数组中。我也有输入[类型=文本]。我需要一个简单的代码来搜索这个数组。 SQL 命令类似于 ：(从 tbl_product 中选择名称，其中名称喜欢 %txt% (。但是我正在前端实现这一点，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可能会有所帮助

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))
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<input type="text" id="mytxt">

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">

使用 array.indexOf 函数怎么样？

products_name = ["product one", "product two"];
function start_search(text){
if(products_name.indexOf(text) > -1){
return true;
}else{
return false;
}
};
start_search('product'); // returns false
start_search('product one'); // returns true
start_search('product two'); // returns true
start_search('product three'); // returns false
