无法获取style属性的值

[linyouzhen124]

使用自定义model的形式进行开发，json数据配置了margin，padding等数据，通过style获取属性值都为默认值，但是页面效果是有的。是不支持在bindView中获取style的值吗？
这是打印的style值：
style: {"aspectRatio":null,"bgColor":-4635,"bgImage":"","bgImgUrl":"","extras":{},"forLabel":"","height":-2,"margin":[0,0,0,0],"padding":[0,0,0,0],"slidable":false,"width":-1,"zIndex":0}

这是data数据：
{
"id": "banner1",
"type": "container-oneColumn",
"style": {
"aspectRatio": 3.223,
"bgColor": "#ffffff",
"margin": [
10,
10,
0,
10
],
"padding": [
5,
10,
5,
10
],
"cols": [
25,
25,
25,
25
],
"cornerRadius": [
15,
15,
15,
15
]
},
"items": [
{
"bizId": "item1",
"type": 110,
"msg": "info1",
"style": {
"bgColor": "#FFEDE5"
}
},
{
"bizId": "item2",
"type": 110,
"msg": "info2"
}
]
}
