转换成json对象报错
js代码
const xhr = new XMLHttpRequest()
xhr.open('GET', '/data/test.json', true)
xhr.onreadystatechange = function () {
if (xhr.readyState === 4) {
if (xhr.status === 200) {
console.log(xhr.responseText)
alert(xhr.responseText)
} else if (xhr.status === 404) {
console.log('404 not found')
}
}
}
xhr.send(null)
xhr.responseText打印出来是这样子
