定義一個(gè)變量a=0，每增加一個(gè)圖片就a++;不用循環(huán)函數(shù)；部分代碼如下:

var ind = 0;
?var al = 0;

var dataInt = {"data":[{"src":"image/P_01.jpg"},{"src":"image/P_02.jpg"},{"src":"image/P_03.jpg"},{"src":"image/P_04.jpg"},{"src":"image/P_05.jpg"},{"src":"image/P_06.jpg"}]};

$(window).on('scroll',function(){
??
??if(checkScrollSlide()){
???if(ind==dataInt.data.length){
????if(al==0){
????alert("圖片已加載完畢！");
????al=1;}
????}else{
???var oBox = $("<div>").addClass("box").appendTo($('#main'));
???var oPic = $('<div>').addClass("pic").appendTo(oBox);
???var oImg = $('<img>').attr('src',dataInt.data[ind].src).appendTo(oPic);
???var minH = Math.min.apply(null,arrH);//定義在函數(shù)外的全局arrH[]，減少選擇器提高性能；
???var minIndex = $.inArray(minH,arrH);
???oBox.css({
????'position':'absolute','top':minH+'px','left':minIndex*w1+'px'
????});
???arrH[minIndex]+=oBox.outerHeight();
???lastBoxTop = oBox.offset().top;
???ind++;
???//if(ind==6){ind=0};//是否循環(huán)加載數(shù)據(jù)；
???console.log(ind);}
???}
??});
