如何在Ajax jQuery中传递我的php session_id（）

Question

// Show Cart Quantity
function showCartById(){
    var inProcess = false;//Just to make sure that the last ajax call is not in process
    if (inProcess) {
        return false;//Another request is active, decline timer call ...
    }
    inProcess = true;//make it burn ;)
    var sId = $(this).attr('sid');
    var data = 'sId='+sId;
    jQuery.ajax({
        url: 'cart.php', //Define your script url here ...
        data: data, //Pass some data if you need to
        method: 'POST', //Makes sense only if you passing data
        success: function(answer) {
            alert(answer)
            inProcess = false;//Queue is free, guys ;)
        },
        error: function() {
            //unknown error occorupted
            inProcess = false;//Queue is free, guys ;)
        }
    });

}

我想通过ajax请求方法传递我的PHP Session_id（）。但是如果没有Session_id（），它会很好地工作。

您可以执行var session_id = '<?php echo session_id();?>';并将其传递给数据
