为什么输入类型的文本在后 jQuery 中是数组

Question

我有这样的表格

    <form id="facform" action="exec/sendfac.php" method="post">
    <input id="mbr_id" class="adresse" name="facdatas[][mbr_id]" type="text" value="" readonly="readonly" />
    <input id="nom" class="adresse" name="facdatas[][nom]" type="text" value="" readonly="readonly" />
    <input id="adresse" class="adresse" name="facdatas[][adresse]" type="text" value="" readonly="readonly"/>
    <input id="ville" class="adresse" name="facdatas[][ville]" type="text" value="" readonly="readonly"/>
    <input name="facdatas[][concerne]" class="concern" value="" type="text">
    <input name="ligneFac[][designation]" type="text" class="facBig" />
    <input name="ligneFac[][unite]" type="text" class="facSmall" />
    <input name="ligneFac[][quantite]" type="text" class="facSmall" />
    <input name="ligneFac[][prixUnite]" type="text" class="facSmall" value="" />
    <input name="ligneFac[][taxe]" type="text" class="facSmall" value="" />
    <input name="ligneFac[][totLine]" type="text" class="facSmall" value="" />
    <input id="send" type="submit" name="submit" value="Envoyer" />

这个表单是用这个 jQuery 发布的

$("#facform").submit(function(e)
{
    var nbr_tr = $('#fac_table tr').length;

    var sendURL = $(this).attr("action");
    var sendPost = $(this).attr("method");
    var facArray = $("#facform").serializeArray();

    $.ajax(
    {
        method: "POST",
        url: sendURL,
        data: facArray,
        success: function(response)
        {
            console.log(response);
            $("#facform").submit();
        }
    });
});

结果给我一个这样的每个文本的数组：

Array ( [facdatas] => Array ( [0] => Array ( [mbr_id] => 26 ) [1] => Array ( [nom] => Gautier Albert ) [2] => Array ( [adresse] => Avenue du Devin du Village 51 ) [3] => Array ( [ville] => 1406 Cronay ) [4] => Array ( [concerne] => TEST ) [5] => Array ( [totalFac] => 69.00 ) ) [ligneFac] => Array ( [0] => Array ( [designation] => Pantalon de training CPNS ) [1] => Array ( [unite] => pièces ) [2] => Array ( [quantite] => 1 ) [3] => Array ( [prixUnite] => 69 ) [4] => Array ( [taxe] => 0.00 ) [5] => Array ( [totLine] => 69.00 ) [6] => Array ( [designation] => ) [7] => Array ( [unite] => ) [8] => Array ( [quantite] => ) [9] => Array ( [prixUnite] => ) [10] => Array ( [taxe] => 0.00 ) [11] => Array ( [totLine] => 0.00 ) [12] => Array ( [designation] => ) [13] => Array ( [unite] => ) [14] => Array ( [quantite] => ) [15] => Array ( [prixUnite] => ) [16] => Array ( [taxe] => 0.00 ) [17] => Array ( [totLine] => 0.00 ) [18] => Array ( [designation] => ) [19] => Array ( [unite] => ) [20] => Array ( [quantite] => ) [21] => Array ( [prixUnite] => ) [22] => Array ( [taxe] => 0.00 ) [23] => Array ( [totLine] => 0.00 ) [24] => Array ( [designation] => ) [25] => Array ( [unite] => ) [26] => Array ( [quantite] => ) [27] => Array ( [prixUnite] => ) [28] => Array ( [taxe] => 0.00 ) [29] => Array ( [totLine] => 0.00 ) ) [submit] => Envoyer ) 

似乎每个字符串都是一个数组，如果我要 print_r($_POST['data']) 它是空的...

第二个问题是如何在没有空行的php中使用这个数组？

有什么想法吗？？

感谢您的帮助

您没有给出任何数据变量，因此它是空的。 可以修改ajax代码为

$.ajax(
    {
        method: "POST",
        url: sendURL,
        data: {data: facArray},
        success: function(response)
        {
            console.log(response);
            $("#facform").submit();
        }
    });

然后你可以让 $_POST['data'] 包含输入。否则 $_POST 将只有所有的输入，而不是数据。
