var cindex=0;
var clength = $("#poject_list > .pitem").length;

        if(cindex>3){
            cindex=0;
            }
        $(this).find(".ptext_bg").css("background","#"+color[cindex]);
        $(this).find(".ptext_bg_2").css("color","#"+color[cindex]);
        cindex++;
        if(i>0&&(i+1)%2==0){
        $(this).css("margin-right",0);
        }
        $(this).attr("index",i);

Answer 1

js里面pitem名称的标签在哪？而且有两个project_iframe的id，id应该是唯一的，可以用name属性
