passing a php array through jquery ajax

Question

I want to pass an array through ajax, but not sure how I would do this.

<input type="button" data-array="'.$array.'" id="button" value="click">

I know I cant put arrays in html, but I couldnt think of how else to explain what I am trying to accomplish.

$('#button').click(function(){
    array = $(this).attr('data-array');
    $.ajax({        
        type    : 'POST',
        dataType : 'json',
        url     : 'ajax.php',
        data    : 'array='+array,
        success : function(data) {
            $('#result').html(data);
        }
    });
});

So I then want to pass that array variable, $array, through to ajax.php. Is this even possible, if so how is it done? I am guess something to do with json?

您可以将它存储在会话变量中，并在需要时稍后调用它，而不是将数组存储在html中。

$_SESSION['dataArray'] = $array;
