Answer 1

function ajax(url,succ) {
var aj=window.XMLHttpRequest?new XMLHttpRequest():new ActiveXObject("Microsoft.XMLHTTP")
aj.open("get", url, true)
aj.send();
aj.onreadystatechange = function() {
if(aj.readyState == 4&&aj.status==200&&succ) {
succ(aj.responseText)
}
}
}

//上面是一个ajax方法。下面是使用。
ajax(url,fuction(res){
console.log(res)

})
//url是json文件的路径，res是获取到后的结果，结果是一个数组。在控制台你自己去看，该怎么提出来。
