我在学习ajax ....我试图从json文件发出一个基本请求，它与我的index.html位于同一个文件夹中，但由于某种原因它说未定义:(我可以看到错误是可变的人，但我不能赶上为什么它未定义....简单的ajax请求加载外部json文件
HTML：
的javascript：
var xhr = new XMLHttpRequest(); //it holds the ajax request
xhr.onreadystatechange = function() { //callback
if(xhr.readyState === 4) {
var people = JSON.parse(xhr.responseText);//it takes the string from the response and it converts it in a javascript object
console.log(people);
for (var i=0; i
var htmlCode = "
" + people[i].name + "
";
}
document.getElementById('personName').innerHTML = htmlCode;
} else {
console.log(xhr.readyState);
}
};
xhr.open('GET', 'addresses.json');
xhr.send();
addresses.json：
{
"people": [
{
"position" : "1",
"name" : "Familia Molina Fernandez",
"streetType" : "C/",
"streetName " : "Nuria",
"streetNumber" : "40",
"floor" : "",
"flat" : "",
"zipCode" : "08202",
"city" : "Sabadell",
"state" : "Barcelona",
"country" : "Spain"
},
{
"position" : "2",
"name" : "Familia Astals Fernandez",
"streetType" : "Avda/",
"streetName " : "Polinya",
"streetNumber" : "61",
"floor" : "1",
"flat" : "1",
"zipCode" : "08202",
"city" : "Sabadell",
"state" : "Barcelona",
"country" : "Spain"
}
]
}
任何想法？
干杯!!!!

'people.length'有没有length属性来调用 –
+1
undefined是错误！ –
+0
ohmg O__O我不是想打电话给任何财产....我通过整个数组的长度试图循环：S Oux等一下....我现在意识到....长度只是用于字符串。 ..不是吗？那我应该用什么？ ：S –
