我正在使用带有chart的Django Rest框架开发一个django应用程序.JS以渲染一些图表。
我的 ajax 电话花了很长时间，我在本地。有没有办法检查什么花了这么长时间才能知道在哪里查找以进行重构？
每次在本地平均需要 10 到 15 秒。例如，这是我的代码：
<script>
var endpoint = 'api/chart/data2'
$('.ajaxProgress').show();
$('.dashboard-container').hide();
function getAvg(grades) {
return grades.reduce(function (p, c) {
return p + c;
}) / grades.length;
}
$.ajax({
method: "GET",
url: endpoint,
success: function(data){
console.log(data)
complete_data = data.team_complete,
info_data = data.team_info_score,
motiv_data = data.team_motiv_score,
action_data = data.team_action_score,
behaviour_data = data.team_behaviour_score,
user_list = data.users,
user_dist = data.user_dist,
info_dist = data.info_dist,
motiv_dist = data.motiv_dist,
action_dist = data.action_dist,
behav_dist = data.behav_dist,
info_label = data.info_label,
motivation_label = data.motivation_label,
action_label = data.action_label,
behav_label = data.behav_label,
complete_label = data.complete_label,
cohesiveness_score = data.cohesiveness_score
var bar_color = [
