js 向数组对象中添加属性和属性值
let resultList = [{"name":"a1"},{"name":"b1"}] resultList.forEach(tem => { tem.age = 1; })
循环向数组resultlist中添加age属性
let resultList = [{"name":"a1","shapes":[{"age":12,"sex":"female"}]},{"name":"b1","shapes":[{"age":10,"sex":"male"}]}] resultList.forEach(item => { item.shapes.forEach(tem => { tem.class = "1"; }) })
向数组中的子属性添加属性
var jsonStr = JSON.stringify(resultList);//将JSON对象转化为JSON字符
或者var jsonStr=resultList.toJSONString(); //将JSON对象转化为JSON字符(需要json包的支持,提示错误可以检查json包版本是否有点低)
