我的javascript返回此错误：$ .ajax不是函数 [英] My javascript is returning this error: $.ajax is not a function
问题描述
不确定有什么问题，但我从Chrome控制台收到此错误：
jquery-3.2.1.slim.min.js:1244 jQuery.Deferred exception: $.ajax is not a function TypeError: $.ajax is not a function
at HTMLDocument.<anonymous> (file:///C:/Users/Adam/Desktop/UseTime/js/example.js:3:7)

at j (jquery-3.2.1.slim.min.js:1193)
at k (jquery-3.2.1.slim.min.js:1199)
从这个JavaScript：
From this JavaScript:
$(function() { //when the DOM is ready
var times; //declare global variable
$.ajax({ //set up request
beforeSend: function (xhr) { //before requesting data
if (xhr.overrideMimeType) { //if supported
xhr.overrideMimeType("application/json"); // set MIME to prevent errors
}
}
});
//funciton that collect data from the json file
function loadTimetable() { //decalre function
$.getJSON('data/example.json') //try to collect json data
.done(function (data) { //if succesful
times = data; //store in variable
}).fail(function () { //if a problem: show message
$('#event').html('Sorry! we couldnt load your time table at the moment');
});
}
loadTimetable(); //call the function
//CLICK ON TEH EVENT TO LOAD A TIME TABLE
$('#content').on('click', '#event a', function (e) { //user clicks on place
e.preventDefault(); //prevent loading page
var loc = this.id.toUpperCase(); //get value of id attr
var newContent = "";
for (var i = 0; i < times[loc].length; i++) { // loop through sessions
newContent += '<li><span class = "time">' + times[loc][i].time + '</span>';
newContent += '<a href = "descriptions.html#';
newContent += times[loc][i].title.replace(/ /g, '-') + '">';
newContent += times[loc][i].title + '</a></li>';
}
$('#sessions').html('<ul>' + newContent + '</ul>'); // Display Time
$('#event a.current').removeClass('current'); // update selected link
$(this).addClass('current');
$('#details').text('');
});
//CLICK ON A SESSION TO LEAD THE DESCRIPTION
$('#content').on('click', '#sessions li a', function (e) { //click on session
e.preventDefault(); // prevent loading
var fragment = this.href; //title is in href
fragment = fragment.replace('#', ' #'); //Add Space before #
$('#details').load(fragment); //to load info
$('#sessions a.current').removeClass('current'); //update selected
});
//CLICK ON PRIMARY NAVIGATION
$('nav a').on('click', function (e) { //click on nav
e.preventDefault(); //prevent loading
var url = this.href; //get UR: to load
$('nav a.current').removeClass('current');
$(this).addClass('current');
$('#container').remove(); //remove old
$('#content').load(url + ' #container').hide().fadeIn('slow'); // add new
});
});
我不确定这是否与我启动.ajax或我的方式有关jquery未正确实现。我觉得是这样的。有什么想法？
I'm not sure if it's an issue with the way I'm initiating .ajax or if my jquery isn't correctly implemented. I think it is. Any Thoughts?
编辑：这是上面脚本的html
edit: here's the html that goes with the script above
<!DOCTYPE html>

推荐答案
您正在使用瘦身版的jQuery。它不支持ajax调用。
使用
You are using slim version of jQuery. It Doesn't support ajax Calling. Use
<script src="https://code.jquery.com/jquery-3.2.1.min.js"></script>
而不是它。
纤细的构建
有时你不需要ajax，或者你更喜欢使用众多
中的一个专注于ajax请求的独立库。通常，对于所有
的web动画，使用CSS和类操作的组合更简单
。除了
包括ajax和效果模块的jQuery的常规版本之外，我们还发布了一个排除这些模块的瘦版本
。总而言之，它排除了ajax，效果，
和当前已弃用的代码。这些天jQuery的大小很少是一个
的负载性能问题，但是苗条的构建大约是6k
gzipped字节小于普通版本--23.6k vs 30k。这些
文件也可以在npm包和CDN中找到：
Sometimes you don’t need ajax, or you prefer to use one of the many standalone libraries that focus on ajax requests. And often it is simpler to use a combination of CSS and class manipulation for all your web animations. Along with the regular version of jQuery that includes the ajax and effects modules, we’ve released a "slim" version that excludes these modules. All in all, it excludes ajax, effects, and currently deprecated code. The size of jQuery is very rarely a load performance concern these days, but the slim build is about 6k gzipped bytes smaller than the regular version – 23.6k vs 30k. These files are also available in the npm package and on the CDN:
