Question

我们正在尝试从javascript / ajax向php发送多个关联数组值，但我们在php文件中收到一个空对象/数组。

那么请你帮忙从javascript到php获取关联数组的值吗？

我们尝试过序列化数组并传递给php文件。
我们尝试将数组转换为字符串，然后尝试将其传递给php文件。

请检查以下代码：

// javscript


function saveData(id) {


    //var actionData = [];
        var actionData = $('#' + id).closest('tr').find("[id^='action_']");
    var ownerData = $('#' + id).closest('tr').find("[id^='owner_']");
    //var type = $.type(actionData);
    //alert(type); exit();

    /*alert(actionData[0]['action']);exit;
    actionData['owner'] = $('#' + id).closest('tr').find("[id^='owner_']");
    actionData[2]['dueDate'] = $('#' + id).closest('tr').find("[id^='dueDate_']");
    actionData[3]['completedDate'] = $('#' + id).closest('tr').find("[id^='completedDate_']");

    //var myData = JSON.stringify(actionData['owner']);

    //alert($('#' + id).closest('tr').find('#projId').val());*/
    var dataObject = [];
    dataObject['projId'] = $('#' + id).closest('tr').find('#projId').val();

    //alert(myData);
  //var newData1 = $.extend({}, actionData['owner']);
  var newData = $.extend({}, dataObject);

        /*dataObject = {
            projId:                  $('#' + id).closest('tr').find('#projId').val(),
            riskNumber:              $('#' + id).closest('tr').children('td#riskNumber').text().slice(0,-4),
            cause:                   $('#' + id).closest('tr').find('#cause').val(),
            effect:                  $('#' + id).closest('tr').find('#effect').val(),

            statusControl:           $('#' + id).closest('tr').find('#statusControl :selected').val()

Answer 1

首先确保您的数据符合您的想法：

var data = JSON.stringify({ data: actionData, owner:ownerData})
console.log(data)

如果是，则在ajax调用中发送数据对象。然后在php端我会确认收到的数据与发送的数据匹配。然后解析说的数据。这可以帮助您缩小范围并解决您的问题。
