jquery小技巧

1. jQuery的each实现continue和break

 

continue----return true || return
break----return false

var arr = [1,2,3,4,5,6,7,8,9,10];

$.each(arr, function(k, v){
    if(k == 3){
        return;
        //return false;
    }else{
        console.log(arr[k]);
    }
});


for(var i = 0; i < arr.length; i++){
    if(k == 3){
        continue;
        //break;
    }else{
        console.log(arr[k]);
    }
}
