The methods I've seen on the Internet would suggest making a new function that calls each function, in turn.

Then, call that new function with the onsubmit attribute. Update: A reader used the "was this post helpful" comment box at the end of this article to ask about providing parameters for some of the functions that are run. When the DoAllThese function is called, provide it with the parameters needed when it runs the functions in its code.

A lack is observed when a false return value of any of the functions needs to abort form processing. For that functionality, the modified DoAllThese function returns the value of the first function that returns a value of false. If none of the functions return a value of false, then DoAllThese returns the value of the last function it called.

Since a "submit" input is already a button, and you want the other button to not be related to submit:. Then, in the JavaScript you need to move the definition of removeTask outside of the IIFE immediately invoked function expression because otherwise it is contained in that function's scope and not accessible by the HTML code.

Alternately, you could establish the handler for the delete button in the init function similarly to how you currently establish the submit handler. I don't have a lot of experience with JS I found a version of the same code without the automatically invoked function. So I am continuing with that I got the alert button to work.

Is there any way to use the onclick html attribute to call more than one JavaScript function? But really, you're better off not using onclick at all and attaching the event handler to the DOM node through your Javascript code. This is known as unobtrusive javascript. I would use the element. From that function you can call multiple functions. The advantage I see in binding an event to a single function and then calling multiple functions is that you can perform some error checking, have some if else statements so that some functions only get called if certain criteria are met.

You can add multiple only by code even if you have the second onclick atribute in the html it gets ignored, and click2 triggered never gets printed, you could add one on action the mousedown but that is just an workaround. You need to take care as the events can pile up, and if you would add many events you can loose count of the order they are ran. But imagine you have a couple of them attached to that same element and want to remove one of them.

It is not possible to remove a single anonymous function from that event listener. This also keeps your code a lot easier to read and maintain. Especially if your function is larger. You can compose all the functions into one and call them. Libraries like Ramdajs has a function to compose multiple functions into one. How are we doing? Please help us improve Stack Overflow.

I also highly recommend jQuery which will really help you with your unobtrusive goal.

You can easily attach event handlers to DOM elements and do much much more all unobtrusively. I've used it for 2 years now and never looked back. If one called action in the onclick fails, the whole thing falls like a domino chain and the onclick fails to work. It's a very common mistake.Given multiple functions, the task is to call them by just one onclick event using JavaScript. Here are few methods discussed. 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.

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.

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

As examples, the br tag isn't a container, but the td tag is. We'll use fictitious function names OneTwoand Three to show how to implement the onclick attribute for calling multiple functions. Separate the function calls in the onclick attribute's value with a semi-colon character and optional space:.

With that method, any values the functions return will be ignored. Which is fine if you don't need a return value. An example would be functions i send you an email, ii make an Ajax request to update a log, and iii spawn an alert box with a thank-you message.

This example contains a div with an onclick attribute that calls the Custom function. Custom calls functions for the onclick attribute and may process values returned from the functions it calls.

The last line of the Custom function that reads as return val; causes the return of the value received from the last function that was called. It is there in case the calling onclick needs the value. A form button might need the value. Here is an example input tag for a form button that needs the returned value so it can return the value to the form. If the Custom function's return is the value false, the submission aborts.

Otherwise, the submission proceeds. Those are the two ways an onclick attribute can cause more than one function to run — listing the functions in the onclick value or calling a custom function to run them. The latter method allows a programmer to make use of function return values. This article first appeared in Possibilities newsletter. Was this article helpful to you?

Height-Responsive Web Pages. Publishing Content From an External File. Color Selector for the Color Blind. Software, your way. WebSite's Secret. Secure Form.In React, the onClick handler allows you to call a function and perform an action when an element is clicked. Therefore, the onClick event handler is one of the most powerful and most used tools in your React tool belt.

The simple App component above has one function called sayHelloand a single button. The button inside the React component has an onClick event handler attached to it, pointing to our sayHello function. Doing so will trigger the function every time you click the button.

How do we trigger the sayHello function? By passing in the name of the function you want to call inside the curly braces, after the event handler:. Notice how we only pass the name of the function to the event handler and not the name followed by parentheses.

Parentheses after a function name executes the function. In other words, if we passed in the function with parentheses, the function will execute every time the component renders. An inline function is a function which is defined inside of the onClick handler when the React Component renders. A common mistake when using inline functions is not including parentheses after the function name.

You may find yourself wanting to call multiple functions after clicking a button. As the example above shows, it is possible to define a block of code inside of the onClick handler. However, depending on the amount of code that you want to run, the block scope can be difficult to read. Again, the code above is not as readable as it could be if we just called the sayHello function and set the state inside of that.

However, there may be instances when you need to do the above. Continue learning about updating state in React components through the onClick event handler in Simplifying React State and the useState Hook. This is also very common when using input elements and the onChange event handler.

Take a look at the example below. The e. Take some time to explore the SyntheticEvent further as there are more useful values inside of it.

You could start by console logging e out and clicking through the object. For example, an admin dashboard which displays a list of users and provides admins with the ability to edit or delete users:. The code above first defines a new array called users with a list of first names.

Then, it loops through those names, rendering a list and button element for each value inside the array. Finally, it passes in the name from the array as an argument of the deleteUserWithName function. Your email address will not be published.
