vue解析前端对象为Array数组并且遍历
例如这个res.data对象：
{
"id": "15",
"name": "火灾"
}
这样子解析吧：
let types = JSON.parse(JSON.stringify(res.data))
console.log("types is " + types)
console.dir(types)
for(var i = 0; i < types.length; i++) {
console.log("types[i] is " + types[i])
console.dir(types[i])
this.disasterTypeOptions.push({
value: types[i].id,
label: types[i].name
})
}
