A Modal Dialog for Vuejs V2

modal-vue

A modal dialog component for Vue.js 2.x

Example image

Skip to the demo section below if you want to see a quick working example.

installation

npm install --save modal-vue

Then, within the <script> tag of the component in which you want to use the modal-vue component you need to import it, and register it as a component.

import Modal from 'modal-vue'
export default {
  components: { Modal },
  ...rest of component properties
}

Refer to the vuejs documentation page for full details of using components.

usage

Let’s start with a quick example extracted from the <template> tag of a component that uses modal-vue. Maybe that’s all you need! but see below for full details of all options.

<modal :showModal="showSourceDialog" :closeAction="closeSourceDialog">
  <h1 slot="header">Select Source</h1>
  <select slot="body" :value="database.source" @change="changeSource($event.target.value)">
    <option v-for="source in ['', ...refdata.sources]">{{ source }}</option>
  </select>
</modal>

properties

modal-vue accepts 3 props which are passed to it as attributes in the <modal> element:

showModal

If true, the modal dialog will be displayed. Pass in whatever state in your application controls this.

closeAction

This is the function to called when the close button of the modal dialog is clicked. This can do whatever you need it to, but don’t forget to change the state which controls the showModal prop or you will have a dialog for life.

containerClass

This is optional and specifies a Bootstrap container class to be used for the <div> that wraps the modal dialog if required.

slots

modal-vue has 3 html slots which are defined as child elements of the <modal> element:

header

This is optional and the contents of it will be used for the heading of the modal dialog. A close button will also be displayed in the header.

If both no header slot and no closeAction prop are defined a dialog without a close button will be displayed. Hopefully in this case you will have provided some other mechanism in the body or footer to allow the dialog to be closed.

body

This defines the contents of the body of the modal dialog. In the example at the start of this section, the body consists of an html select dropdown including an onChange handler. In this example when the onChange handler is fired the dialog is closed, so no need for any footer buttons etc.

footer

This defines the contents of the body of the modal dialog. Often it might be used for such things as Ok / Cancel buttons.

dependencies

This component uses Bootstrap v3 for CSS. If you are not already using Bootstrap, you can find installation instructions here.

demo

You can see a demo of modal-vue here:

Make Pop-Up Modal Window In Vanilla JavaScript [2022]

Make Pop-Up Modal Window In Vanilla JavaScript


Learn how to create a simple responsive pop-up modal window using Vanilla JavaScript along with HTML and CSS with a bit of Flexbox.

Create A Button That Opens Pop Up Modal Window

Declare a <button> HTML element with an id open-modal.

<button id="open-modal">Open Modal Window</button>

The goal is when a user presses this button, the pop-up modal window will open.

Style the button using CSS Flexbox and centre it on the screen.

* {
    margin: 0;
    padding: 0;
    font-family: Arial, Helvetica, sans-serif;
    box-sizing: border-box;
}

body {
    height: 100vh;
    display: flex;
    align-items: center;
    justify-content: center;
}

button {
    padding: 10px;
    font-size: 1.1em;
    background: #32bacf;
    color: white;
    border: none;
    border-radius: 10px;
    border: 1px solid rgba(0, 0, 0, 0.2);
    cursor: pointer;
}

button:hover {
    background: rgba(0, 0, 0, 0.7);
}

Create Pop-Up Modal Overlay

Normally, pop-up modal windows have overlays with a transparent darker background that covers the entire browser screen.

Define a div with an id model-overlay which will cover the entire screen.

<div id="modal-overlay">
<div>

Then, make it to full screen using height:100vh CSS property.

Bring it in front of the button by using position:absolute with a transparent background colour.

#modal-overlay {
    width: 100%;
    height: 100vh;
    position: absolute;
    background: rgba(0, 0, 0, 0.7);
}

I just added the border to see the boundaries of the modal-overlay element.

Center Pop-Up Modal Window To The Modal Overlay

Create a div with an id modal inside the modal-overlay element, which will be an actually pop-up modal window that user interacts with.

<div id="modal-overlay">
  <div id="modal">
  </div>
<div>

Add CSS style to make it visible on the screen.

Adding width:100% and max-width:650px will make sure the width of the pop-up modal window won’t exceed when the browser width is more than 650px.

If the browser width is less than 650px, the pop-up modal window will stretch the width to fill the screen which is normally for mobile viewports.

#modal-overlay #modal {
    max-width: 650px;
    width: 100%;
    background: white;
    height: 400px;
}

Centre the pop-up modal window to the screen using Flexbox.

To do that, just add the three lines of Flexbox code to the modal-overlay which are

  • display:flex → Convert an HTML element to Flexbox
  • align-items:center → centre the pop-up modal window vertically to the viewport
  • justify-content:center → centre the pop-up modal window horizontally to the viewport
#modal-overlay {
   ...
  
   display: flex;
   align-items: center;
   justify-content: center;
}

Open Up Pop-Up Modal Window On Button Click

Now we have the basic pop-up modal window designed using CSS.

Make it visible when a user presses the open modal button.

To do that,

First, hide the modal overlay by default by changing its display property from flex to none.

#modal-overlay {
   ...
  
   display: none; // Changed from flex to none
   align-items: center;
   justify-content: center;
}

Create a DOM reference to the open-modal button as well as the modal-overlay elements.

const openModalButton = document.getElementById("open-modal");
const modalWindowOverlay = document.getElementById("modal-overlay");

Attach a click event to the openModalButton with the callback arrow function showModalWindow.

const showModalWindow = () => {
    modalWindowOverlay.style.display = 'flex';
}

openModalButton.addEventListener("click", showModalWindow);

Set the display property of the modalWindowOverlay to flex inside showModalWindow() function which will open up the modal window.

As you can see, there is no way we can close/hide the pop-up modalwindow after its became visible on the screen.

Let’s fix it!

Close/Hide Pop-Up Modal Window On Button Click

Typically, there will be a close button on the top or bottom right side of the pop-up modal window.

Let’s add a close button on the bottom left side of the modal window.

Define header, content and footer HTML elements inside the pop-up modal window.

<div id="modal">

    <div class="modal-header">
        <h2>Modal Pop Up Window</h2>
    </div>

    <div class="modal-content">
        <p>Modal Content</p>
    </div>
    
    <div class="modal-footer">
        <button id="close-modal">Close</button>
        <button>Save</button>
    </div>

</div>

Generally, you’ll have two buttons on the footer of the pop-up modal window, which may be save and close.

Let’s push the buttons to the bottom using Flexbox.

Turn the display property of the pop-up modal window to flex and set the flex direction to column.

jQuery Ajax CRUD in ASP.NET Core MVC with Modal Popup

In this article, we’ll discuss how to use jQuery Ajax for ASP.NET Core MVC CRUD Operations using Bootstrap Modal. With jQuery Ajax, we can make HTTP request to controller action methods without reloading the entire page, like a single page application.

To demonstrate CRUD operations – insert, update, delete and retrieve, the project will be dealing with details of a normal bank transaction. GitHub repository for this demo project : https://bit.ly/33KTJAu.

Sub-topics discussed :

  • Form design for insert and update operation.
  • Display forms in modal popup dialog.
  • Form post using jQuery Ajax.
  • Implement MVC CRUD operations with jQuery Ajax.
  • Loading spinner in .NET Core MVC.
  • Prevent direct access to MVC action method.

Create ASP.NET Core MVC Project

In Visual Studio 2019, Go to File > New > Project (Ctrl + Shift + N).

From new project window, Select Asp.Net Core Web Application_._

Once you provide the project name and location. Select Web Application(Model-View-Controller) and uncheck HTTPS Configuration. Above steps will create a brand new ASP.NET Core MVC project.

Showing project template selection for .NET Core MVC.

Setup a Database

Let’s create a database for this application using Entity Framework Core. For that we’ve to install corresponding NuGet Packages. Right click on project from solution explorer, select Manage NuGet Packages_,_ From browse tab, install following 3 packages.

Showing list of NuGet Packages for Entity Framework Core

Now let’s define DB model class file – /Models/TransactionModel.cs.

public class TransactionModel
{
    [Key]
    public int TransactionId { get; set; }

    [Column(TypeName ="nvarchar(12)")]
    [DisplayName("Account Number")]
    [Required(ErrorMessage ="This Field is required.")]
    [MaxLength(12,ErrorMessage ="Maximum 12 characters only")]
    public string AccountNumber { get; set; }

    [Column(TypeName ="nvarchar(100)")]
    [DisplayName("Beneficiary Name")]
    [Required(ErrorMessage = "This Field is required.")]
    public string BeneficiaryName { get; set; }

    [Column(TypeName ="nvarchar(100)")]
    [DisplayName("Bank Name")]
    [Required(ErrorMessage = "This Field is required.")]
    public string BankName { get; set; }

    [Column(TypeName ="nvarchar(11)")]
    [DisplayName("SWIFT Code")]
    [Required(ErrorMessage = "This Field is required.")]
    [MaxLength(11)]
    public string SWIFTCode { get; set; }

    [DisplayName("Amount")]
    [Required(ErrorMessage = "This Field is required.")]
    public int Amount { get; set; }

    [DisplayFormat(DataFormatString = "{0:MM/dd/yyyy}")]
    public DateTime Date { get; set; }
}

C#Copy

Here we’ve defined model properties for the transaction with proper validation. Now let’s define  DbContextclass for EF Core.

#asp.net core article #asp.net core #add loading spinner in asp.net core #asp.net core crud without reloading #asp.net core jquery ajax form #asp.net core modal dialog #asp.net core mvc crud using jquery ajax #asp.net core mvc with jquery and ajax #asp.net core popup window #bootstrap modal popup in asp.net core mvc. bootstrap modal popup in asp.net core #delete and viewall in asp.net core #jquery ajax - insert #jquery ajax form post #modal popup dialog in asp.net core #no direct access action method #update #validation in modal popup
