    头等鸡尾酒
    
    我在哪里失败了???提前感谢您浪费时间阅读本文!
    谢谢大家!

    您正在生成一个多级数组:

    array_push($result, array('poza' => $row[1], etc...);
    
    将创建一个类似于:

    $result = array(
         0 => array('poza' => ....)
    );
    
    意思是你必须使用

          $("ul").append("<li>Poza: "+this[0]['poza']+ etc...);
                                          ^^^---- note this
    

    同样,您的JS代码似乎假设只有一行数据从数据库中出来,但您的数据库处理代码被设置为处理多行数据。我无法判断哪一个是正确的,但您应该知道。

    问题是
    cockbox.php
    包含HTML,而
    $.getJSON
    函数需要JSON(且仅限于JSON)。对于类似于
    application/JSON
    的JSON,您还应该返回一个有效的
    Content-Type
    头。最后,您的
    cockbox.php
    将如下所示:

    <? 
    
    include_once('includes/connection.php');
    
    header('Content-Type: application/json');
    
    $sql = 'SELECT poza, nume, compozitie FROM cocktail';
    $res = mysql_query($sql);
    $results = array();
    
    while( $row = mysql_fetch_assoc($res) ) {
    
        $results[] = $row;
    
    }
    
    echo json_encode( array('results' => $results) );
    
    ?>
    
    $(document).ready(function () {
    
        var updateList = function () {
    
            $.getJSON('cocktail.php', function( data ) {
    
                var list = $('ul');
    
                list.empty();
    
                $.each(data.results, function( index, result ) {
    
                    list.append(
                        '<li>Poza: ' + result.poza + '</li>' +
                        '<li>Nume: ' + result.nume + '</li>' +
                        '<li>Compozitie: ' + result.compozitie + '</li>'
                    );
    
                });
    
            });
        };
    
        window.setInterval(updateList, 200);
    
    });
    
    应该是

    $.each(data.result, function ( index, value ) {
    
    你也应该更换

    this['poza']
    

    最后,您的JavaScript将如下所示:

    <? 
    
    include_once('includes/connection.php');
    
    header('Content-Type: application/json');
    
    $sql = 'SELECT poza, nume, compozitie FROM cocktail';
    $res = mysql_query($sql);
    $results = array();
    
    while( $row = mysql_fetch_assoc($res) ) {
    
        $results[] = $row;
    
    }
    
    echo json_encode( array('results' => $results) );
    
    ?>
    
    $(document).ready(function () {
    
        var updateList = function () {
    
            $.getJSON('cocktail.php', function( data ) {
    
                var list = $('ul');
    
                list.empty();
    
                $.each(data.results, function( index, result ) {
    
                    list.append(
                        '<li>Poza: ' + result.poza + '</li>' +
                        '<li>Nume: ' + result.nume + '</li>' +
                        '<li>Compozitie: ' + result.compozitie + '</li>'
                    );
    
                });
    
            });
        };
    
        window.setInterval(updateList, 200);
    
    });
    
    $(文档).ready(函数(){
    var updateList=函数(){
    $.getJSON('cockbox.php',函数(数据){
    变量列表=$('ul');
    list.empty();
    $.each(data.results,function)(索引,结果){
    list.append(
    “
  • Poza:”+result.Poza+“
  • ”+ “
  • Nume:”+result.Nume+“
  • ”+ “
  • 复合材料:”+result.Compozitie+“
  • ” ); }); }); }; setInterval(updateList,200); });
    sooo
    cockbox.php
    是否显示正确的数据?但是
    script1.js
    无法使用
    $.getJSON
    获取它。。。对吗?你有什么错误吗?
    updates
    函数是否实际被调用?数据是空白还是…?在
    $.getJSON(“cockbox.php”,function(data){
    行之后,
    $data的值是多少?
    $每个
    都是一个语法,错误也是…应该是…。页面cockbox.php它显示来自mysql的数据,但以原始方式:{“result”:[{“poza”:“\/images\/cockle\/mojito.jpg\/>,“nume”:“Mojito”,“compozitie”:“15cl rom,gheata,menta”}]}脚本应该将它排列在一个更干净的列表中,这就是我想要成功的。
    $(document).ready(function () {
    
        var updateList = function () {
    
            $.getJSON('cocktail.php', function( data ) {
    
                var list = $('ul');
    
                list.empty();
    
                $.each(data.results, function( index, result ) {
    
                    list.append(
                        '<li>Poza: ' + result.poza + '</li>' +
                        '<li>Nume: ' + result.nume + '</li>' +
                        '<li>Compozitie: ' + result.compozitie + '</li>'
                    );
    
                });
    
            });
        };
    
        window.setInterval(updateList, 200);
    
    });
