只需执行ajax hello-world 练习，我就无法加载<script src="https://code.jquery.com/jquery-3.2.1.slim.min.js" integrity="sha384-KJ3o2DKtIkvYIK3UENzmM7KCkRr/rE9/Qpg6aAZGJwFDMVNA/GpGFF93hXpG5KkN" crossorigin="anonymous"></script>

<script type="text/javascript">
$(document).ready(function() {
$('#my-input').select2({
placeholder: "Search for something",

dataType: 'json',
delay: 250,
data: function(params) {

processResults: function (data, params) {
params.page = params.page || 1;
data.hits = $.map(data.hits, function(obj) {

return obj;
});
return {

},

}
});
});
</script>
数据，而是收到错误：
未捕获的TypeError：c.ajax不是函数
at Object.transport（select2.min.js：1）
在d（select2.min.js：1）
我的代码：
{{1}}
答案 0 :(得分：4)
基础问题出现在jquery-3.2.1.slim.min.js，根据some sources ajax已经从精简版jquery中移除，因此要使select2再次工作，需要包括完整jquery的版本：
<script src="https://code.jquery.com/jquery-3.3.1.min.js" integrity="sha256-FgpCb/KJQlLNfOu91ta32o/NMZxltwRo8QtmkMRdAu8=" crossorigin="anonymous"></script>
