onclick 按钮只显示一次 toastr 并将错误消息分组到 toastr

Question

i am using toastr jquery plugin. below is the link

https://github.com/scottoffen/jquery.toaster

i am facing 2 issues here

1. Currently Multiple notifications displayed on click of button (please refer attached image)

   Expected: it should show one notification each time of click, if notification exist do not show another one.

   2. Way to group multiple notifications

   Expected: Group Name and password together as a single notification

Code

$(".actions").on("click", ".startWorkflowD", function() {

    //Disable Start workflow button
    $('.startWorkflowD').attr('disabled', 'disabled');

    var userDisplayName = $("#HEADER_USER_MENU_POPUP_text").text().toLowerCase();
    var actualUserDisplayName = $("#name").val().toLowerCase();

    if (userDisplayName != actualUserDisplayName) {
        $.toaster({
            priority: 'warning',
            title: 'Authentication Failed',
            message: '<br/>' + 'Please enter valid Name (First name and Last name), to start the workflow.'
        });

        //Enable start workflow button
        $('.startWorkflowD').removeAttr("disabled");

        return;
    }

    var password = $("#Password");

    if (password.val().length == 0) {
        // password is empty
        $.toaster({
            priority: 'warning',
            title: 'Authentication Failed',
            message: '<br/>' + 'Please enter valid Password, to start the workflow.'
        });

        //Enable start workflow button
        $('.startWorkflowD').removeAttr("disabled");
    }

});

Any help is appreciated

i tried below stackoverflow answer, my toastr does not have **"preventDuplicates": true,** in options

toastr (jquery) must only show once

Answer 1

It may help some one. Here is a sample demo I did.

• Duplicates not allowed
• Progress Bar

Options are there with Icons

<input type="text" name="name" id="name" placeholder="Name" />
<br>
<input type="password" name="Password" id="Password" placeholder="Password" />
<br>
<input type="button" class="actions" value="Login" />
