【前台 ajax】web项目前台传递数组给后台 两种方式

 1 //首先 是数组数据的封装
 2 $.each(checkedNodes,function(i,node){
 3                     nodeArr.push(node.id);
 4                 });
 5 //ajax中  需要设置 traditional:true,
 6                 if(roleName !="" ){
 7                     $.ajax({url:"roleAdd.htmls",
 8                             dataType:'json',
 9                             type:"post",
10                             traditional:true,
11                             data:{
