I got a lot of weird getters and setters instead of values. What is even more interesting is that looks like arguments are mutating, because pay attention to object "preview" on top, it's differs from what we see after revealing this object in console. NeXTs I get the same thing. Then you could temporarily use values. That is very bizarre. I'm not seeing that at all. For example, the submit validation example doesn't exhibit this behavior.

Sure, I've tried many various releases, neither 6a15 or 6a6 helps I've tried react-hot-loader v1, then v3, then come back to v1. Please take a look at this example in your free time, I have no more ideas what could be wrong as for this moment.

Hm, looks like redux-form differs between that one in examples and published into npm or something. NeXTs The source code that is identical to the npm published lib is going to be under the specific tag for that version. I have already made changes to the examples in the v6 branch that will make it not work with the version published on npm.

I'm having the same page reload problem after submitting with "redux-form": "6. I suppose you have also incorrectly use onSubmit function. I had the same issue with my page refreshing on form submit. It was not very clear from docs for me that it would be the case. I still can't resolve the issue. I don't understand solution too well since I'm new to React. Can someone provide their code or a deeper explaination? Thank you, but I still can't quite resolve it.

It says onSubmit is undefined.

I am not exporting the code to any other modules or using hot reloading etc. I suppose explanation is here. I get the same problems refreshing, if I don't manually call preventDefault and some weird object instead of the formdata. I'm using react AndreasHoermandinger pay attention to comment. NeXTs I got. Is this the problem? I circumvented this by preventDefault and selecting the fields, but according to what's written in the docs that should not happen. NeXTs I am still seeing this issue on latest redux form in ie I haven't had a good chance to look, but where is it calling prevent default on the submit event?

I see where it is doing this now. I was struggling with this issue as well but really reading comment helped me out. It appears reduxForm takes your passed onSubmit prop, wraps it and injects it into the wrapped form component as handleSubmit.Sponsored by and others.

Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. I was trying to make a chat application using node. I'm fairly new to web development so forgive me if my issue is extremely obvious.

My code can be found below:. For some reason the alert in my submit function is never reached. It just refreshes the page whenever I hit the button. How do I fix my page's behavior, and what tools might I consider using to analyze this issue more closely? Sounds to me like a delegation issue - I'll bet chat isn't in the DOM when you are creating the submit handler. This is default HTML behavior. Buttons are submit buttons by default, so clicking them will submit the form.

If you don't want that, then make it a "dumb" button:. The other issue is, as explained in the other answer, that you are trying to bind the event handler before the button exists. The way you mix jQuery and React is messy, makes your code harder to maintain and harder to reason about. Just keep everything inside the React component:. Similarly, messageData should be part of the state of the component, but I leave the conversion up to you.

Basically the way you use React currently doesn't give you much benefit. Your problem is something to do with controlled and uncontrolled components in React. In controlled component: A handler function would take care of the action upon submit. Example for controlled component:.

Welcome to WebmasterWorld! Remove the return false. You might put that on the form onsubmit handler, but it's not going to help on the button element and even putting it on the form onsubmit handler is not ideal. Then it won't try to submit the form.

A few suggestions: 1. Use an HTML5 doctype. It's backwards compatible with HTML 4. Preferably, put them in external. It's better for performance, reusability, and maintenance. In your functions, put all your variable declarations at the very beginning of the function. You don't have to search all over to determine if a variable is global or if it has function scope.

Try using preventDefaultit's a jQuery function for preventing default actions called by the browser.

I return false in the jQuery 'submit' event. Keenan Diggs. Keenan Diggs Keenan Diggs 1 1 gold badge 1 1 silver badge 7 7 bronze badges.HTML form elements work a little bit differently from other DOM elements in React, because form elements naturally keep some internal state.

For example, this form in plain HTML accepts a single name:. This form has the default HTML form behavior of browsing to a new page when the user submits the form. If you want this behavior in React, it just works. In React, mutable state is typically kept in the state property of components, and only updated with setState.

Then the React component that renders a form also controls what happens in that form on subsequent user input. For example, if we want to make the previous example log the name when it is submitted, we can write the form as a controlled component:. Try it on CodePen. Since the value attribute is set on our form element, the displayed value will always be this. Since handleChange runs on every keystroke to update the React state, the displayed value will update as the user types.

While this means you have to type a bit more code, you can now pass the value to other UI elements too, or reset it from other event handlers. Notice that this. For example, this HTML creates a drop-down list of flavors:. Note that the Coconut option is initially selected, because of the selected attribute. React, instead of using this selected attribute, uses a value attribute on the root select tag.

This is more convenient in a controlled component because you only need to update it in one place. For example:. You can pass an array into the value attribute, allowing you to select multiple options in a select tag:. Because its value is read-only, it is an uncontrolled component in React. It is discussed together with other uncontrolled components later in the documentation.

When you need to handle multiple controlled input elements, you can add a name attribute to each element and let the handler function choose what to do based on the value of event. Note how we used the ES6 computed property name syntax to update the state key corresponding to the given input name:. Also, since setState automatically merges a partial state into the current statewe only needed to call it with the changed parts.

Specifying the value prop on a controlled component prevents the user from changing the input unless you desire so. The following code demonstrates this. The input is locked at first but becomes editable after a short delay. It can sometimes be tedious to use controlled components, because you need to write an event handler for every way your data can change and pipe all of the input state through a React component.

This can become particularly annoying when you are converting a preexisting codebase to React, or integrating a React application with a non-React library. In these situations, you might want to check out uncontrolled componentsan alternative technique for implementing input forms. Edit this page. Main Concepts.
