jquery包装器遍历和数组遍历小结

    //jquery数组遍历
    var arr = [1,2,3];
    $.each(arr, function(i,val){
       console.log(i); 
       console.log(val);
    });
    0,1
    1,2
    2,3

    //js数组遍历 5中
    var numbers = [1,2,3,4,5,6];
    var everyResult = numbers.every(function(item,index,array){
        console.log(item);
        console.log(index);
        console.log(item);
        return item;
    });
    everyResult();

    //jquery包装器的遍历
    $(‘.content-hot-slider input‘).each(function(){
        var text = $(this).val();
        if (/^[\u4e00-\u9fa5]{1,4}$/.test(text)) {
            check[i] = true;
        }
        else {
            check[i] = false;
        }
    });
