所以，我正在尝试在用户点击按钮后显示“减号（连字符）”符号。到目前为止，我尝试过的代码不起作用。你能指出错误在哪里吗？
<a role="button" data-toggle="collapse" data-parent="#accordion"
href="#collapse<?php echo $i; ?>" aria-expanded="false" aria-
controls="collapse<?php echo $i; ?>" class="collapsed text15">
<i class="more-less glyphicon glyphicon-plus"></i>
Slot Name
</a>
我尝试使用此代码，但它无效。
jQuery('#accordion').on('shown.bs.collapse', function () {
jQuery(".glyphicon").removeClass("glyphicon-plus").addClass("glyphicon-minus");
});
jQuery('#accordion').on('hidden.bs.collapse', function () {
jQuery(".glyphicon").removeClass("glyphicon-minus").addClass("glyphicon-plus");
});

您可以添加 AuthenticationResult result = null;
try
{
string userObjectID = (User.FindFirst("http://schemas.microsoft.com/identity/claims/objectidentifier"))?.Value;
AuthenticationContext authContext = new AuthenticationContext(Startup.Authority, new NaiveSessionCache(userObjectID, HttpContext.Session));
ClientCredential credential = new ClientCredential(Startup.ClientId, Startup.ClientSecret);
result = await authContext.AcquireTokenSilentAsync("https://graph.windows.net", credential, new UserIdentifier(userObjectID, UserIdentifierType.UniqueId));
var userData = new
{
accountEnabled = true,
displayName = "nan yu",
mailNickname = "nanyu",
passwordProfile = new
{
password = "xxxxxx",
forceChangePasswordNextLogin = false
},
userPrincipalName = "nanyuTest54@testbasic1.onmicrosoft.com"
};
// Forms encode todo item, to POST to the Azure AD graph api.
HttpContent content = new StringContent(JsonConvert.SerializeObject(userData), System.Text.Encoding.UTF8, "application/json");
//
// Add the azure ad user.
//
HttpClient client = new HttpClient();
HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Post, "https://graph.windows.net/myorganization/users?api-version=1.6");
request.Headers.Authorization = new AuthenticationHeaderValue("Bearer", result.AccessToken);
request.Content = content;
HttpResponseMessage response = await client.SendAsync(request);
//
// Return user in the view.
//
if (response.IsSuccessStatusCode)
{
return RedirectToAction("Index");
}
else
{
//
// If the call failed with access denied, then drop the current access token from the cache,
// and show the user an error indicating they might need to sign-in again.
//
if (response.StatusCode == System.Net.HttpStatusCode.Unauthorized)
{
}
}
}
catch (Exception ee)
{
//
// The user needs to re-authorize. Show them a message to that effect.
//
}
并使用以下脚本代替此

你也可以用CSS

content: "\e113";
float: right;
}

$(".glyphicon").removeClass选择所有图标，这可能不是您想要的。使用$(e.target).prev().find("i")代替图标。检查这个工作演示：
$(function() {
$(".collapse").on('show.bs.collapse', function(e) {
if ($(this).is(e.target)) {
snippet.log("show "+this.id)
}
$(e.target).prev().find("i").removeClass("glyphicon-plus").addClass("glyphicon-minus");
})
$(".collapse").on('hidden.bs.collapse', function(e) {
if ($(this).is(e.target)) {
snippet.log("hide "+this.id)
}
$(e.target).prev().find("i").removeClass("glyphicon-minus").addClass("glyphicon-plus");
})
});<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
