Read Fourth dimension: v mins Languages:
In this quick article, nosotros'll talk over how to display a confirm dialog box using JavaScript. The confirm dialog box allows you to perform actions based on the user input.
JavaScript is one of the core technologies of the web. The majority of websites employ it, and all modern web browsers support it without the demand for plugins. Hither at Envato Tuts+, we're discussing tips and tricks that volition help yous in your mean solar day-to-twenty-four hours JavaScript development.
Equally a JavaScript developer, yous oft demand to take user input in the class of yep or no question, and based on that you want to perform sure operations. Specifically, there are certain operations that are sensitive and can't exist undone, and you lot would similar to warn or confirm with users if they actually intend to perform the functioning, so they don't do it mistakenly. For example, if there's a delete link which allows y'all to delete an entity from a database, you would like to ostend with users if they really want to delete information technology. So even if users click on the delete link by mistake, they at to the lowest degree become a chance to abolish it.
In this mail, I'll bear witness you 2 means to confirm a user action in JavaScript: using the confirm method and using a hidden confirmation div.
Syntax of the confirm Method
In JavaScript, you lot tin can use the confirm method of the window object to brandish a dialog box, and await for the user to either confirm or cancel it. Today, nosotros'll talk over how it works along with a real-world example.
In this section, we'll get through the syntax of the window.confirm method.
The syntax of the confirm method looks similar this:
var result = window.confirm(message);
The confirm method takes a single string statement, and yous can pass a message which you desire to display in a dialog box. It'due south an optional argument, but you'll want to pass a sensible message—otherwise a blank dialog box with yes and no options will be displayed and probably won't make any sense to your visitors. Ordinarily, a message is in the form of a question, and a user is presented with two options to choose from.
In a dialog box, at that place are two buttons: OK and Abolish. If a user clicks on the OK push button, the ostend method returns true, and if a user clicks on the cancel button, the ostend method returns false. So you lot can use the render value of the confirm method to know the user's selection. (If you want the buttons to say something dissimilar, like Yes and No, I'll show you lot how at the bottom of this post.)
Since the window object is always implicit, which is to say its backdrop and methods are always in scope, y'all can also call the confirm method, as shown in the following snippet.
var result = confirm(message);
It'southward of import to annotation that the confirmation dialog is modal and synchronous. Thus, JavaScript code execution is stopped when the dialog is displayed, and information technology is continued after the user dismisses the dialog box by clicking on either the OK or cancel button.
So that'due south an overview of the syntax of the confirm method. In the next section, we'll go through a real-globe example.
A Real-World Case of the ostend Method
In this department, we'll go through a existent-globe example which demonstrates how you tin can employ the ostend method in JavaScript.
Take a look at the following case.
When a user clicks on the Delete My Profile! button, information technology calls the deleteProfile function. In the deleteProfile function, we've called the ostend method which presents the confirmation dialog box to the user.
Finally, if a user clicks on the OK button in that confirmation dialog, we'll get ahead and redirect the user to the /deleteProfile.php page, which volition perform the delete performance. On the other hand, if a user clicks on the Abolish button, we won't do anything. JavaScript execution is halted until the user makes a choice and dismisses the confirmation dialog box.
So that's how you tin can use the confirm method in JavaScript to nowadays a yes or no selection dialog box.
Confirm Yeah or No With a Hidden Div
There are some drawbacks of using the ostend method to get user confirmation. 1 is that the confirmation dialog will not exist part of your app or website'due south UI. It will not use your branding or colour scheme. It too cannot be customized, for example if you want to say Yep or No instead of OK and Abolish. Finally, the confirmation dialog is modal, and then as long as it is beingness displayed, the user will not be able to interact with whatsoever other part of your app'southward interface.
Another way to confirm aye or no is with a subconscious div on your page. Take a look at the following example:
In this example, we take a hidden confirmation div with the id confirm. To show the div, we simply set up its hidden property to truthful. We set hidden to truthful when we desire to show the confirmation, and set information technology to false again to hide information technology.
Every bit you tin can come across, this method of confirming yes or no allows us more flexibility and customization than the window.confirm method.
Determination
Today, nosotros discussed two means to get user confirmation in JavaScript. Outset nosotros looked at the simplest manner: the window.confirm method. However, this doesn't create a peachy user experience. Then I showed you how to utilise a hidden div to get user confirmation with more control over how the confirmation will look and behave.
