1.遍历数组
var arr1=['aa','bb','cc','dd']; $.each(arr1,function(i,val){ //两个参数,第一个参数表示遍历的数组的下标,第二个参数表示下标对应的值 console.log(i+'```````'+val); 输出的结果为: 0```````aa 1```````bb 2```````cc 3```````dd
2.当二维数组中有Json对象
var arr3=[{name:'n1',age:18},{name:'n2',age:20},{name:'n3',age:22}]; $.each(arr3,function(i,val){ console.log(i+'`````'+val); #输出 # 0`````[object Object] 1`````[object Object] i2`````[object Object] console.log(val.name); //获取每一个json里面的name值 console.log(val["name"]); $.each(val,function(key,val2){ console.log(key+'```'+val2); }) });
