Question

因此，我是2012年用skratch制成的大型旧后端上的错误。

我不是AJAX专业人士，但设法在控制台中看到此错误：

VM687:1 Uncaught SyntaxError: Unexpected token '<'
    at XMLHttpRequest.xhr_object.onreadystatechange (core.js:1050)

https://i.stack.imgur.com/HBRsL.jpg

这就是它涉及的core.js部分：

function gestionFactureDetail(prd, action) {
    var a = document.getElementById(prd);
    var data = 'a=a';
    data = data + '&action=' + action;


    for (var i = 0; i < a.length; i++) {
        if (a.elements[i].tagName == 'INPUT' || a.elements[i].tagName == 'SELECT') {
            if (a.elements[i].type == 'checkbox') {
                if (a.elements[i].checked == true) {
                    data = data + "&" + a.elements[i].name + '=1';
                } else {
                    data = data + "&" + a.elements[i].name + '=';
                }
            } else {
                data = data + "&" + a.elements[i].name + '=' + a.elements[i].value;
            }
        }
        if (a.elements[i].tagName == 'TEXTAREA') {
            var b = a.elements[i].value;
            data = data + "&" + a.elements[i].name + '=' + escape(b);
        }
    }

    var xhr_object = null;
    if (window.XMLHttpRequest) // Firefox
        xhr_object = new XMLHttpRequest();
    else if (window.ActiveXObject) // Internet Explorer
        xhr_object = new ActiveXObject("Microsoft.XMLHTTP");
    else { // XMLHttpRequest non supporté par le navigateur
        alert("Votre navigateur ne supporte pas les objets XMLHTTPRequest...");
        return;
    }
    xhr_object.open("GET", 'facture_gestion_req.php?' + data, true);
    xhr_object.onreadystatechange = function () {
        if (xhr_object.readyState == 4) {
            eval(xhr_object.responseText);
        }
    }
    xhr_object.send(null);

}

javascript控制台引用的“ 1050”行恰好在最后一行之前：

eval(xhr_object.responseText);

我还可以按照您的意思为您提供PHP代码：

facturelibre_gestion_req.php

<?php
include("inc/connection.php");

$action = $_GET["action"];
$contenu_factnum = $db->quote($_GET["contenu_factnum"] ? $_GET["contenu_factnum"] : 0);
$contenu_num = $db->quote($_GET["contenu_num"]);
$contenu_produit = $db->quote($_GET["contenu_produit"]);
$contenu_tva = $db->quote($_GET["contenu_tva"]);
$contenu_pu = $db->quote($_GET["contenu_pu"]);
$contenu_remise = $db->quote(trim($_GET["contenu_remise"], ' %'));
$contenu_qtite = $db->quote($_GET["contenu_qtite"]);
$contenu_montant = $db->quote($_GET["contenu_montant"]);
$eta_num = $db->quote($_GET["eta_num"]);
$eta_num_non_quote = $_GET["eta_num"];

if ($action == "creer")
{
    $add = $db->query(
        "INSERT INTO facture_contenu (
            contenu_factnum,
            contenu_texte,
            contenu_tva,
            contenu_pu,
            contenu_remise,
            contenu_qtite,
            contenu_montant
        ) VALUES (
            $contenu_factnum,
            $contenu_produit,
            $contenu_tva,
            $contenu_pu,
            $contenu_remise,
            $contenu_qtite,
            $contenu_montant
         )"
    );
}
if ($action == "maj") {
    $del =
        $db->query("
            UPDATE
                facture_contenu
            SET
                contenu_texte   = $contenu_produit,
                contenu_tva     = $contenu_tva,
                contenu_pu      = $contenu_pu,
                contenu_remise  = $contenu_remise,
                contenu_qtite   = $contenu_qtite,
                contenu_montant = $contenu_montant
            WHERE
                contenu_num     = $contenu_num
        ");
}
if ($action == "sup") {
    $del =
        $db->query("
            DELETE FROM
                facture_contenu
            WHERE
                contenu_num     = $contenu_num
        ");
}

如果您有任何想法或线索，请让我知道，因为我完全迷路了...：（
