我正在使用jQuery Nestable(http://dbushell.github.io/Nestable/)。
当我更改可嵌套元素的顺序时,我试图从中拦截数据。
$('.dd').nestable().on('change', function() {
var json_text = $('.dd').nestable('serialize');
$.post("/includes/processes/core.php", {
cmd: 'nestable',
table: table,
data: json_text
}, function(response){
alert(response);
});
});
在core.php中,我已经完成了:
$data = $_POST['data'];
$data = json_decode($data, true);
function parseJsonArray($jsonArray, $parentID = 0) {
$return = array();
foreach ($jsonArray as $subArray) {
$returnSubSubArray = array();
if (isset($subArray['children'])) {
$returnSubSubArray = parseJsonArray($subArray['children'], $subArray['id']);
}
$return[] = array('id' => $subArray['id'], 'parentID' => $parentID);
$return = array_merge($return, $returnSubSubArray);
}
return $return;
}
$readbleArray = parseJsonArray($data);
比我必须操纵这个数组,但我不能继续,因为响应是:
"json_decode() expects parameter 1 to be string, array given in core.php on line (where is "$data = json_decode($data, true;")"
如果我用json_encode($ data)更改json_decode($ data,true),这是响应:
"Invalid argument supplied for foreach() in core.php on line (where is "foreach ($jsonArray as $subArray);")"
请帮我..
最佳答案
尝试删除此行,因为$ .post不执行json编码。
$data = json_decode($data, true);
