Do multiple things in Onclick?

There are two ways to do many things with one click:

1. Put all the function calls into the onclick attribute’s value. Separate the function calls in the onclick attribute’s value with a semi-colon character and optional space: onclick=”One(); Two(); Three()”
2. Create a custom function to call the other functions.

The first solution to perform multiple onClick events in React is to include all of your actions inside of a function and then call that single function from the onClick event handler. Let’s explore how to do that in a React Component: import React from ‘react’; function App() { function greeting() { console.

In order to pass a value as a parameter through the onClick handler we pass in an arrow function which returns a call to the sayHello function. In our example, that argument is a string: ‘James’: return ( sayHello(‘James’)}>Greet ); …

-> on click of a button you need to check data from two functions with (click) attribute. Do you : A) create a third function which encapsulates the two & pass that in the (click). B) you pass both of them.

JavaScript | call multiple functions in onclick event. Example 2: This example first calls a single function and now it is responsibility of that function to call the others. This example does the same. JavaScript | call multiple functions in onclick event.

Each of these links has an anonymous function tied to them meaning they don’t have any variable tied to them except that tag’s onclick value. Plus if you wanted to, you could include more lines of code this way, all grouped up in one tidy location.

The first way to perform multiple onClick events in React is to write your logic in a single function, and then call that function inside of the onClick event handler. To learn more about the onClick event handler in React, check out my tutorial on React onClick Event Handling with Examples.

Multiple Functions With One Onclick. The onclick attribute can be used in div tags, form buttons, img image tags, a link tags, and other HTML containers.

Given multiple functions, the task is to call them by just one onclick event using JavaScript. Either we can call them by mentioning their names with element where onclick event occurs or first call a single function and all the other functions are called inside that function.

The onclick event generally occurs when the user clicks on an element. It allows the programmer to execute a JavaScript’s function when an element gets clicked. This event can be used for validating a form, warning messages and many more. Using JavaScript, this event can be dynamically added to any element.

The button includes the onclick attribute, which causes the showAlert() to be called when a user clicks the button. If a user navigates to the button using the tab key, then presses enter, that too will trigger the alert.

You can create a single function that calls both of those, and then use it in the event.

The Html is an event attribute, which executes a script when the button is clicked. This attribute is supported by all browsers. It is also used to call a function when the button is clicked.

Reveal content with a link click. Make a div disappear when it’s clicked. Check an email address with a button click. Send the browser to a different URL when the content in a span tag is clicked. Pretty much anything a web developer can come up with. Here’s an example onclick attribute to spawn an alert box.

For some reason, the event handler is being called twice. Here is my button (I am using a php object to generate the code, that’s why there are a lot of empty tags):

Additional attributes (in this case, the second onClick) will be ignored. So, instead of onclick calling both fbLikeDump (); and WriteCookie ();, it will only call fbLikeDump ();. To fix, simply define a single onclick attribute and call both functions within it:
