我使用Grails
<formRemote>
代码和Bootstrap Modal
在登录页面上工作
一切正常,但我不知道如何在登录成功后关闭de modal。
使用:
$('#myModal').modal('hide')
登录失败后,我使用我的控制器( LoginController )返回的errorMessage更新 #modal-body ,这很好但登录成功时( ajaxSuccess < / strong> LoginController中的方法)我重定向到主页,我不知道如何告诉模式此时关闭。
非常感谢一些帮助。
以下是发送 AJAX 调用的表单模板代码段。
<g:formRemote url="[controller:'j_spring_security_check', action:'']"
name="loginForm"
update="modal-body"
class="form-inline"
on401="alert('error');">
<input type="text" name="j_username" class="input" placeholder="email" autocomplete="on" value="" id="j_username">
<input type="password" name="j_password" class="input" placeholder="password" value="" id="j_password">
<input id="loginButton" type="submit" value="Login" class="btn"
data-trigger="manual" data-toggle="popover" data-placement="bottom" data-html="true" data-content="<span></span>" />
<div class="login-message" id="login-message">${message}</div>
</g:formRemote>
<script>
<g:if test="${message == 'success'}">
$(function() {
$('#myModal').modal('hide');
});
</g:if>
</script>
这是引导模式代码段,用于在#modal-body
中呈现loginForm模板<div id="cont">
<div class="modal fade hide" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true" data-remote="">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h3 id="myModalLabel">Login/Register</h3>
</div>
<div id="modal-body" class="modal-body">
<g:render template="/login/templates/loginForm"></g:render>
</div>
<div class="modal-footer">
<button class="btn" data-dismiss="modal" aria-hidden="true">Cancel</button>
</div>
</div>
</div>
这是来自 LoginController 的 authfail 和 ajaxSuccess 方法
def authfail = {
def username = session[UsernamePasswordAuthenticationFilter.SPRING_SECURITY_LAST_USERNAME_KEY]
String errorMessage = ''
def exception = session[WebAttributes.AUTHENTICATION_EXCEPTION]
if (exception) {
if (exception instanceof AccountExpiredException) {
errorMessage = g.message(code: "springSecurity.errors.login.expired")
}
else if (exception instanceof CredentialsExpiredException) {
errorMessage = g.message(code: "springSecurity.errors.login.passwordExpired")
}
else if (exception instanceof DisabledException) {
errorMessage = g.message(code: "springSecurity.errors.login.disabled")
}
else if (exception instanceof LockedException) {
errorMessage = g.message(code: "springSecurity.errors.login.locked")
}
else {
errorMessage = g.message(code: "springSecurity.errors.login.fail")
}
}
if (springSecurityService.isAjax(request)) {
render(template: '/login/templates/loginForm', model: [message:errorMessage])
//render(errorMessage)
}
else {
render view: '/index' , params: params
//redirect action: 'auth', params: params
//render([error: msg] as JSON)
}
}
这是 ajaxsuccess 方法
def ajaxSuccess = {
render(template: '/login/templates/loginForm', model: [message:"success"])
}
我保留评论行,以便您可以看到我尝试做的事情。
提前感谢

如果你的gsp看起来像这样:
<div id="modal-body">
<g:render template="/login/templates/loginForm" model="[errorMessage:'none']" />
</div>
<g:formRemote ....
你可以简单地在模板中添加一些javascript,它将在Dom完全使用ajax响应更新时运行 并确保将errorMessage变量初始化为如上所述设置为“none”
<div id="cont">
<div class="modal fade hide" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true" data-remote="">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h3 id="myModalLabel">Login/Register</h3>
</div>
<div id="modal-body" class="modal-body">
<g:render template="/login/templates/loginForm"></g:render>
</div>
<div class="modal-footer">
<button class="btn" data-dismiss="modal" aria-hidden="true">Cancel</button>
</div>
</div>
</div>
<script>
<g:if test="${errorMessage == 'success'}">
// it will only close if the errorMessage from ajax is 'success, wich by the way is not an error ^^
$(function() {
$('#myModal').modal('hide');
});
</g:if>
</script>
