Angular.forEach用法
阿新 • • 發佈:2018-12-23
1.針對物件迴圈(key,value)
官方示例:
var values = {name: 'misko', gender: 'male'}; var log = []; angular.forEach(values, function(value, key) { this.push(key + ': ' + value); }, log); expect(log).toEqual(['name: misko', 'gender: male']);
2.針對物件陣列(key,value)
非官方示例:
var objs =[{a:1},{a:2}]; angular.forEach(objs,function(data,index,array){ //data等價於array[index] console.log(data.a+'='+array[index].a); });
3.針對物件陣列(data)
非官方示例:
var objs =[{a:1},{a:2}]; angular.forEach(objs, function(data){ console.log(data.a); });
