javascript - 搜索数组，按与查询的相关性显示结果

Question

我想在 JavaScript 数组中执行搜索，显示与查询相关的所有结果，相当于以下 SQL 语句:

"SELECT * FROM table WHERE column LIKE input"

这是一个例子:

var array = [];
array[0] = "Apple";
array[1] = "Apricot";
array[2] = "Pear";
array[3] = "Peacock";

假设我的查询字符串是“ap”，它将按以下顺序返回结果:

1. "Apple"
2. "Apricot"

query = "p"
result:

1. "Pear"
2. "Peacock"
3. "Apple"
4. "Apricot"

query = "r"
result:

1. "Apricot"
2. "Pear"

这在 JavaScript 中可能吗？怎么办？

Answer 1

试试这个，

    var arr = [];
    arr[0] = "Apple";
    arr[1] = "Apricot";
    arr[2] = "Pear";
    arr[3] = "Peacock";

    var resultArr=[];
    var str='ap'//string to search

    for(var i=0;i<arr.length;i++){
      if(arr[i].indexOf(str) != -1){
         resultArr.push(arr[i]);
      }
    }

  alert('search results:'+resultArr);
    //resultArr contains reults
