In your ajax configuration you use results you should use processResults
在你的 ajax 配置中你使用 results 你应该使用 processResults
Try this
尝试这个
var baseurl = $("#baseurl").val();
$(".myselect").select2({
placeholder: "Select a inspector",
allowClear: true,
ajax: {
url: baseurl + '/admin/getdata',
dataType: 'json',
type: "GET",
quietMillis: 50,
data: function (term) {
return {
term: term.term
};
},
processResults: function (data) {
var myResults = [];
$.each(data, function (index, item) {
myResults.push({
'id': item.id,
'text': item.firstname
});
});
return {
results: myResults
};
}
}
});

Aamir@, sometimes errors are misleading. If you see from your code, it doesn't have a reference to b at all. I believe that must be an error that is being thrown from a method outside of your code, due to an error in your code.
Aamir@，有时错误具有误导性。如果您从代码中看到，它根本没有对 b 的引用。我相信这一定是由于代码中的错误而从代码之外的方法抛出的错误。
You might have to set a break point by clicking on the line number on browser console and then check the call stack to find the error in the code.
您可能必须通过单击浏览器控制台上的行号来设置断点，然后检查调用堆栈以查找代码中的错误。
