前端修改數(shù)據(jù)之后，需要把修改后的字段信息發(fā)送給后臺的數(shù)據(jù)都是放在post請求的data中就可以了嗎 window.onload= function(){ var xhr = new XMLHttpRequest(); var msg = {"name":"zqian","age":"17"}; xhr.open('post','http://rap2api.taobao.org/app/mock/12040/ptest',true); xhr.setRequestHeader('Content-Type','application/x-www-form-urlencoded'); xhr.send(JSON.stringify(msg)); xhr.onreadystatechange = function(){ if(xhr.readyState == 4){ if(xhr.status >=200 && xhr.status <300 ||xhr.status ==304){ console.log(xhr.response); } } }
