我有以下脚本,它根据表单参数从服务器获取数据。
protected void beforeForgetPasswordDialog(Form f) {
TextField emailTextField = new TextField();
f.add(emailTextField);
Button submit = new Button("Submit");
submit.addActionListener(e -> {
Style s = UIManager.getInstance().getComponentStyle("Label");
String forgottenPasswordEmail = emailTextField.getText();
if (forgottenPasswordEmail != null && !forgottenPasswordEmail.equals("")) {
ForgetPasswordConnection fpc = new ForgetPasswordConnection();
fpc.forgetPasswordConnectionMethod(forgottenPasswordEmail, s, StateMachine.this, f);
forgetPasswordSuccess = fpc.abc;
if (forgetPasswordSuccess) {
showForm("Main", null);
}
} else {
//Dialog.show(null, "Email id is empty", "ok", null);
//Dialogbox works here, but toastBar doesnt work
// f.addShowListener(d -> {
// ToastBar.showMessage("Email id is empty", FontImage.MATERIAL_MAIL_OUTLINE, 2000);
// });
}
});
f.add(submit);
}
此部分正在运行,有时根据搜索条件,需要几秒钟才能获得结果。同时我想展示一些GIF说数据加载。我准备好了GIF。如何在上面的脚本中实现它?

请试试这个。
jQuery('#request_search').submit(function(e){
$("#report").html("<div><img src='loading.gif' alt='Loading.. \n Please wait' title='Loading.. \n Please wait'` /></div>");
e.preventDefault();
var s_date=jQuery('#actualfrom').val();
var e_date=jQuery('#actualto').val();
var type=jQuery("#type").val();
var loc=jQuery("#loc").val();
jQuery.post("scripts/get_gamma_activity_type.php", {"loc":loc,"start_date":s_date, "end_date":e_date, "type":type}, function(data) {
jQuery('#report').html(data);});
});
});

使用 id 属性在 html 文件中添加带路径的图片,然后显示/隐藏div 根据要求和成功。
尝试以下代码:
在 html 文件中添加html div:
<div id='loadingmessage' style='display:none'>
<img src='loadinggraphic.gif'/>
</div>
尝试下面的代码 jQuery :
jQuery('#request_search').submit(function(e){
$('#loadingmessage').show(); // show the loading message.
e.preventDefault();
var s_date=jQuery('#actualfrom').val();
var e_date=jQuery('#actualto').val();
var type=jQuery("#type").val();
var loc=jQuery("#loc").val();
jQuery.post("scripts/get_gamma_activity_type.php", {"loc":loc,"start_date":s_date, "end_date":e_date, "type":type}, function(data) {
jQuery('#report').html(data);});
$('#loadingmessage').hide(); // hide the loading message
});
});
