Question

我一直在努力将结果限制在我网站中包含的搜索脚本中。

这是原始剧本：

jQuery(function() {
  // Initialize lunr with the fields to be searched, plus the boost.
  window.idx = lunr(function () {
    this.field('id');
    this.field('title');
    this.field('content', { boost: 10 });
    this.field('categories');
  });

  // Get the generated search_data.json file so lunr.js can search it locally.
  window.data = $.getJSON('/search.json');

  // Wait for the data to load and add it to lunr
  window.data.then(function(loaded_data){
    $.each(loaded_data, function(index, value){
      window.idx.add(
        $.extend({ "id": index }, value)
      );
    });
  });

  // Event when the form is submitted
  $("#site_search").submit(function(event){
      event.preventDefault();
      var query = $("#search_box").val(); // Get the value for the text field
      var results = window.idx.search(query); // Get lunr to perform a search
      display_search_results(results); // Hand the results off to be displayed
  });

  function display_search_results(results) {
    var $search_results = $("#search_results");

    // Wait for data to load
    window.data.then(function(loaded_data) {

      // Are there any results?
      if (results.length) {
        $search_results.empty(); // Clear any old results

        // Iterate over the results
        results.forEach(function(result) {
          var item = loaded_data[result.ref];

          // Build a snippet of HTML for this result
          var appendString = '<li><a href="' + item.url + '">' + item.title + '</a></li>';

          // Add the snippet to the collection of results.
          $search_results.append(appendString);
        });
      } else {
        // If there are no results, let the user know.
        $search_results.html('<li><b><u>NO RESULTS FOUND</u></b></li>');
      }
    });
  }
});

我在尝试迭代结果时试图将此限制语句包括在内，但没有成功：

        // Iterate over the results
    for (var i = 0; i < results.length && i < 5; i++)  {
         var item = loaded_date[results[i]];

我已经玩了很长一段时间了，似乎无法找到什么是错误的。

非常感谢任何帮助。

你得到了什么错误，你的for循环看起来很好。

另一种方法是使用Array#slice来限制迭代结果的数量。

<?php
/
$action=$_POST['action'];
if ($action=="insert_marketer"){
    insert_marketer();
}

function insert_marketer(){

    $marketer=mysqli_connect("localhost","root","","marketer detail");
    $username = $_POST['username'];

    var_dump("$username");
    $password = $_POST['password'];
    $phone_number = $_POST['phone_number'];

    if (!empty($username) && !empty($password)&& !empty($phone_number) ){

        $password=crypt('$password');

        $result = mysqli_query($marketer,"INSERT INTO 'marketer detail'('username','password','phone_number')VALUES('$username','$password','$phone_number')");
        if($result)
        {
            var_dump('$password'); 
            echo "New record created successfully";
        }
        else {
            echo "Error: ". mysqli_error($marketer);
        }

    }
    mysqli_close ($marketer) ;
}

?>

将您现有的迭代替换为结果，其中包含results.slice(0, 5).forEach(function (result) { // snip })。

即使结果少于5个，这也会有效，如果结果超过5个，则会采用前5个。
