Question

当我尝试使用DataTables JQuery插件时，我遇到了一个问题。

SyntaxError: JSON.parse: unterminated string at line 1 column 1572865 of the JSON data

我认为这是我从3000行查询中切割的大型数据库中编码JSON的方式，因为如果我一次性执行此操作，则会出现内存不足错误：

$rowNum = $this->db->query("SELECT ID WHERE CONDITION")->result_array();
$pas = 3000;
for($i = $rowNum[0]; $i < count($rowNum); $i = $i+$pas) { // Loop wrinting rows 3000 per 3000 in a JSON
    $begin = $rowNum[$i];
    $end = (empty($rowNum[$i+($pas-1)])) ? end($rowNum) : $rowNum[$i+($pas-1)];
    $query = "
            LARGE QUERY FOR HAVING THE WHOLE TABLE AND ID BETWEEN {$begin} AND {$end} ";
    $rows = $this->db->query($query)->result_array();
    $line = json_encode($rows);
    file_put_contents(FCPATH."application/ajax/GuyaforTable_brut.json", $line, FILE_APPEND | LOCK_EX);
}
$charMappings = [
    '][' => ',',
];
$content = file_get_contents(FCPATH."application/ajax/GuyaforTable_brut.json");
file_put_contents(FCPATH."application/ajax/GuyaforTable_brut.json", strtr($content, $charMappings));

JSON的第1行第1572865行：

不确定这是否仍然是您的问题，但是如果您在Firefox devtools中遇到该错误，似乎将在即将发布的版本（61）中修复：https://bugzilla.mozilla.org/show_bug.cgi?id=1223726

devtools正在截断一定大小的响应（不影响实际代码）。
