jquery ajax 设置请求头header 参数

$.ajax(
                {
                    url:'http://127.0.0.1:30080/api-a/quasiCustom/selectCustomList',
                    type:'post',
                    dateType:'json',
                    beforeSend: function(xhr) {
                        xhr.setRequestHeader("organId:'1333333333'");
                    },
                    headers:{'Content-Type':'application/json;charset=utf8','organId':'1333333333'},
                    data:JSON.stringify(org),
                    success:function(data){console.log("sucess");},
                    error:function(data){console.log("error");}
                }
            );

var mobile = $('.phone_input').val();
var verifyCodeData={};
                 verifyCodeData['aliSessionId']=aliSessionId;
                 verifyCodeData['aliToken']=aliToken;
                 verifyCodeData['aliSig']=aliSig;
                 verifyCodeData['aliScene']=aliScene;
                 verifyCodeData['mobile']=mobile;
               
                 $.ajax({
                		 type: "POST",
                		 url:"/user/popUserSecurity/getVerifyCode.json",
                		 data:{"verifyCodeData":JSON.stringify(verifyCodeData)},
                		 headers:{
                		        "ip":returnCitySN["cip"] 
                		    },
            		    success: function(data){
        	       			if(data.code == '1'){
        	                       if(state){
        	                           time();
        	                       }
        	                       state = false;
        	                   }else{
        	                  	 layer.alert(data.message, {icon: 2});
        	                   }
        	              	
        	                   window.ic.reset();
        	                   aliVerifyStatus=false;
        	       		  }               		 
                         });                               
             });

JSON.stringify(verifyCodeData)：   返回值一个表示给定值的JSON字符串。

JSON.stringify({x: 5, y: 6});              
// "{"x":5,"y":6}"

jQuery中ajax的4种常用请求方式：

利用索引操作多个相同元素：   

var index = $(this).index();

$(document).on("click",".del",function(){  			
        			var index = $(this).index();
        			$(".del").eq(index-1).parents(".feed_img").remove(); 	
        			if($(".addFeedbach_img").length < 6){ 
    					$("#addImg_up").show();
    				}
        		});
