javascript - Echo JS onclick 填充功能 AJAX 不工作

Question

我有一个带有 AJAX、MySQL、PHP 和 JS 的搜索栏。搜索栏在列表的 div 中提供实时搜索结果，并在这方面发挥作用。

我的问题是单击时 div 列表中的实时搜索结果不会填充搜索栏的输入。什么也没有发生，列表一直保持打开状态，除非我点击退出。我曾经让它在我的旧代码中工作，当你点击任何结果时它会填充搜索栏的输入，但是自从我重写了整个代码后我就无法弄清楚为什么 onclick 和 fill 函数现在不起作用。

我如何修复此代码，以便当用户点击实时搜索结果列表中的结果之一时，它会填充搜索栏的输入？

这是我已经尝试过的并且目前在以下文件中作为我的代码的内容:

index.php

<form>  
 <input type="text" id="search" class="search" data-js="form-text" 
 placeholder="Search Over 100+ Resources..." autocomplete="off">
 <button type="submit" class="Button" value="Submit"><i class="fa fa- 
 search"></i></button>
 <div id="display"></div>
 <div id="backspace" style="display:none"></div>
</form>

script.js

//Getting value from "ajax.php".
function fill(Value) {
//Assigning value to "search" div in "index.php" file.
$('#search').val(Value);
//Hiding "display" div in "index.php" file.
$('#display').hide();
}
$(document).ready(function() {
//On pressing a key on "Search box" in "indexd.php" file. This function will 
be called.
$("#search").keyup(function() {
//Assigning search box value to javascript variable named as "name".
$('#display').hide();
$('#backspace').css("display", "none");
var name = $('#search').val();
//Validating, if "name" is empty.
if (name == "") {
   //Assigning empty value to "display" div in "index.php" file.
   $('#backspace').css("display", "block");
}
//If name is not empty.
else {
    //AJAX is called.
    $.ajax({
        //AJAX type is "GET".
        type: "GET",
        //Data will be sent to "ajax.php".
        url: "ajax.php",
        //Data, that will be sent to "ajax.php".
        data: {
            //Assigning value of "name" into "search" variable.
            search: name
        },
        //If result found, this funtion will be called.
        success: function(html) {
            //Assigning result to "display" div in "index.php" file.
            $("#display").html(html).show();
        }
    });
   }
 });
});

ajax.php

<?php
//Including Database configuration file.
include "db.php";
//Getting value of "search" variable from "script.js".
if (isset($_GET['search'])) {
//Search box value assigning to $Name variable.
$Name = $_GET['search'];
//Search query.
$Query = "SELECT Name FROM search WHERE Name LIKE '$Name%' LIMIT 5";
//Query execution
$ExecQuery = MySQLi_query($con, $Query);
//Creating unordered list to display result.
    if ($ExecQuery->num_rows > 0) {
          echo "<ul>";
          while ($Result = MySQLi_fetch_array($ExecQuery)) {
            echo "<li onclick='fill".$Result['Name']."'>".$Result['Name']." 
     </li>";
     }
    echo "</ul>";
   }
  }
 die();
?>

您可以使用 ` 符号代替 javascript 的单引号和双引号。

在这里，您应该像这样更新 ajax.php 文件中的第 16 行。

echo "<li onclick='fill(`".$Result['Name']."`)'>".$Result['Name']." 

完整代码ajax.php文件

<?php
//Including Database configuration file.
include "db.php";
//Getting value of "search" variable from "script.js".
if (isset($_GET['search'])) {
//Search box value assigning to $Name variable.
$Name = $_GET['search'];
//Search query.
$Query = "SELECT Name FROM search WHERE Name LIKE '$Name%' LIMIT 5";
//Query execution
$ExecQuery = MySQLi_query($con, $Query);
//Creating unordered list to display result.
    if ($ExecQuery->num_rows > 0) {
          echo "<ul>";
          while ($Result = MySQLi_fetch_array($ExecQuery)) {
            echo "<li onclick='fill(`".$Result['Name']."`)'>".$Result['Name']." 
     </li>";
     }
    echo "</ul>";
   }
  }

JS 代码。

//Getting value from "ajax.php".
function fill(Value) {
//Assigning value to "search" div in "index.php" file.
$('#search').val(Value);
//Hiding "display" div in "index.php" file.
$('#display').hide();
}
$(document).ready(function() {
//On pressing a key on "Search box" in "indexd.php" file. This function will be called.
$("#search").keyup(function() {
//Assigning search box value to javascript variable named as "name".
$('#display').hide();
$('#backspace').css("display", "none");
var name = $('#search').val();
//Validating, if "name" is empty.
if (name == "") {
   //Assigning empty value to "display" div in "index.php" file.
   $('#backspace').css("display", "block");
}
//If name is not empty.
else {
    //AJAX is called.
    $.ajax({
        //AJAX type is "GET".
        type: "GET",
        //Data will be sent to "ajax.php".
        url: "ajax.php",
        //Data, that will be sent to "ajax.php".
        data: {
            //Assigning value of "name" into "search" variable.
            search: name
        },
        //If result found, this funtion will be called.
        success: function(html) {
          if (html == '<ul><li>No Result Found!</li></ul>') {
             $('#no-results').css("display", "block");
          }else{
             //Assigning result to "display" div in "index.php" file.
             $("#display").html(html).show();
           }
        }
    });
   }
 });
});
