使用json.stringify将Javascript数组转换为PHP

Question

I have an array of divs is js:

[div#heaolu, div#edu, div#usk, div#lootus, div#heaenergia]

I need to pass that to PHP.

JS:

function send(){
            console.log(sendarray);

            JSON.stringify(sendarray);
}

PHP:

$posts = json_decode($_POST['sendarray']);


print_r($posts); 
echo json_last_error();

print_r return nothing and json_last_error returns 0 in firefox

In chrome it throws me: Uncaught TypeError: Converting circular structure to JSON

Answer 1

您输入的内容不是有效的javascript对象，您必须将元素包装在" 。此外，请查看@Rahul Desai的答案，您需要使用ajax将数据发送到服务器。

["div#heaolu", "div#edu", "div#usk", "div#lootus", "div#heaenergia"]
