【问题描述】：
首先我能够接收到 JSON 文件，但是在做了一些我不记得接收 JSON 文件时出现错误。
我正在获取输入的值，然后调用一个 url，接收这个 JSON 文件，然后将其解析到表中。
当我收到错误消息后页面也会重新加载
function getPokemon() {
var Value = $("#intvalue").val();
var url = "http://pokeapi.co/api/v2/pokemon/" + Value + "/";
//alert(url);
$.ajax({
type: 'GET',
url: url,
//force to handle it as text
dataType: 'text',
success: function(data) {
//data downloaded so we call parseJSON function
//and pass downloaded data
var json = $.parseJSON(data);
//now json variable contains data in json format
//let's display a few items
$('#ID').html(json.id);
$('#name').html(json.name);
$('#Experience').html(json.base_experience);
$('#Height').html(json.height);
$('#Weight').html(json.weight);
$('#numAbility').html(json.abilities.length);
},
error: function() {
alert("Unable to retreive JSON file");
//console.log(data);
}
});

-
为什么会失败？在不知道为什么失败的情况下，除了疯狂的猜测之外，没有人可以帮助您。改进您的错误处理程序并观察控制台/网络选项卡。
-
原来是一个简单的 async: false 修复它，至于页面的自动重新加载我通过删除
-
这不是解决 ajax 问题的好方法（除了导致浏览器冻结片刻之外，应该对您的给定代码没有影响。）
