Property referenced in indexed property path is neither an array nor a List nor a Map

记一次传参请求报错，没有解决

Invalid property 'distributeCars[0][ackStatus]' of bean class [com.api6.plate.prototype.dailyoffice.car.entity.ApprovalForCar]: Property referenced in indexed property path 'distributeCars[0][ackStatus]' is neither an array nor a List nor a Map; returned value was [com.api6.plate.prototype.dailyoffice.car.entity.DistributeCar@11;id=null]

$.ajax({
url: "${pageContext.request.contextPath}/app/carmange/saveSupplemental",
data: $form.serialize()+'&'+JSON.stringify($.param(data)),//获得表单数据
dataType:'json',
success: function(m){

复杂传值list 如果是distributeCars[0].ackStatus,就可以。

JavaScript模拟表单（带数组的复杂数据结构）提交

function test(){

    var typeArray = new Array();

    typeArray.push("mm");

    typeArray.push("gg");

    var demoarry = new  Array();

    demoarry.push("dd");

    demoarry.push("qq");

    typeArray.push(demoarry);

    console.log(typeArray);

    var id = 0;

    var data = {

        id:  id ,

        type: typeArray,

        demoarry : demoarry

    };

    httpPostUrlExt("http://www.baidu.com",data);

}

function httpPostUrlExt(url, data) {

    var temp = document.createElement("form");

    temp.action = url;

    temp.method = "post";

    temp.style.display = "none";

    for (var x in data) {

        if(Object.prototype.toString.call(data[x]) === '[object Array]' ) {

            var arr = data[x];

            while(arr.length){

                var opt = document.createElement("textarea");

                opt.name = x;

                opt.value = arr.pop();

                temp.appendChild(opt);

            }

        } else {

            var opt = document.createElement("textarea");

            opt.name = x;

            opt.value = data[x];

            temp.appendChild(opt);

        }

    }

    document.body.appendChild(temp);

    console.log(temp);

    //temp.submit();

    return temp;

}
