尽管遵循了我在此处找到的所有示例,但我仍然无法从服务器端 ASP.NET 代码中打开模式引导程序窗口。代码执行,我没有收到 JavaScript 错误,但模态窗口从未出现。
这是模态窗口 HTML:
<div id="StatusPopUp" class="modal fade" role="dialog">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">
×</button>
<h4 class="modal-title">Credentials Not Found</h4>
</div>
<div class="modal-body">
<p class="text-justify">
The email address and/or password entered do not match our records. Please try your login again if you believe this is an
error.
</p>
<p class="text-justify">
If you are an associate and need credentials for use of the Portal then please contact your regional office
or Team Sales Lead to request them.
</p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-danger" data-dismiss="modal">
Close</button>
</div>
</div>
</div>
</div>
这是打开模态的Javascript代码:
<script type="text/javascript">
function Show() {
$("#StatusPopUp").modal("show");
}
</script>
最后,这是服务器端用于打开模态的代码:
protected void btnGo_Click(object sender, EventArgs e) {
bool isValid=Membership.ValidateUser(UName.Value,Pwd.Value);
if ( isValid )
this.Response.Redirect ( "associates/home.aspx", true );
else
ClientScript.RegisterStartupScript ( this.GetType ( ), "alert", "Show();", true );
}
目标是当用户尝试在登录页面上登录但不成功时,模态应该弹出一条消息。正如我所说,所有代码都按照编写的方式执行,但它仍然没有让模式窗口真正出现在浏览器中。帮助?
答案 0 :(得分:0)
如果模式的显示仅在页面重新加载时从服务器端响应触发,我会稍微重构一下,使用 asp:panel
并将 javascript 移动到您的常规 jquery $(document).ready()
功能。
通过这种方式,模态 HTML 甚至不会在需要之前呈现,并且您可以更好地控制何时调用显示模态的脚本。您不必处理任何外部脚本加载等。
