layer iframe大致使用

function addOrUpdate(id,type) {
    if(type == 'update'){
        var title = "修改";
    }
    if(type == 'add'){
        var title = "新增";
    }

    var typeid = "${typeid}"
    var url = "<s:url value='/aaaa.shtml'></s:url>" + "?id=" + id + "&typeid=" + typeid;
    layer.open({
        type: 2,
        title: title,
        //shadeClose: true,
        skin: 'layui-layer-lan',
        shade: [0.5, '#393D49'],
        maxmin: true, //開啟最大化最小化按鈕
        area: ['1000px', '600px'],
        content: url,
        btn: ['保存', '取消'],
        yes: function (index, layero) { //或者使用btn1
            var body = layer.getChildFrame('body', index);
            var commitForm = body.find('#myform');
            var iframeWin = window[layero.find('iframe')[0]['name']];
            var flag = iframeWin.checkInfo();
            if (flag) {
                var formData = commitForm.serialize();
                saveNews(formData);
            }
        }, btn1: function (index) {
            layer.close(index);
        }
    });
}
function saveNews(formData) {
    var url="<s:url value="/bbbbbb.shtml"/>";
    $.ajax({
        cache: true,
        type: "POST",
        url:url,
        data:formData,
        async: false,
        success: function(data) {
            if(data){
              
            }else {
                layer.alert("保存失敗！", {
                    icon: 5,
                    skin: 'layer-ext-moon',
                    anim: 6
                });
                return false;
            }
        }

    });
}



iframe層為form表單

 <form action="" method="post" id="myform" enctype="multipart/form-data">
        <div class="form-group row">
            <div class="left col-xs-3 text-right">
            <label for="">名稱:</label>
            </div>
            <div class="right col-xs-8 text-left">
            <input type="text" class="form-control" id="name" name="name" placeholder="">
            </div>
        </div>
    </form>


function checkInfo（）{
//檢測參數，返回flag
}
