Does this. If it's a string, it should be converted to HTML just fine. Source on npmjs. If you have control over where the string containing html is coming from ie. For example:. In my case, I used react-render-html.
I could not get npm build to work with react-html-parser. I had a requirement to show few html unicode charactersbut they should not be directly embedded in the JSX. Within the JSX, it had to be picked from the Component's state. Component code snippet is given below :. Learn more. Asked 3 years, 6 months ago. Active 2 months ago. Viewed k times.

The node is text because is escaped The node is a dom node because isn't escaped. Sergio Flores Sergio Flores 3, 3 3 gold badges 30 30 silver badges 51 51 bronze badges.
This was the issue. The description string was escaped HTML. I unescaped it and now it works fine. Appreciate the mention KunalParekh, but they're different things. My answer is only valid if the html is located within your app meaning it's actually JSX. To parse HTML from an external source to jsx you'd need to seek another solution. Example: class App extends React.

Could you paste here console.So, for those who were still having trouble in setting up their form validations in cleaner, elegant way, I hope you may find this article helpful in your use-case as I got into the same painful situation of looking for an elegant way to validate my form inputs.
Coding field validations programmatically yourself can be tedious work, repetitive because this is already a solved problem and we already have an API for this, and most especially your code could be prone to errors if not managed properly. I remembered a lot of bloated logic for form validations I made back then in jQuery days and it was horrible where I can simply look for a simple solution that solves the problem.
Forms were one of the fundamental functionalities in any web applications we make, and equally as complex sometimes. So we spend most of our times adding input field elements and code some validation checks on it which our work could get tedious and at times very lengthy for just basic functionality.
This goes to show that form validations were actually a big deal for most developers to start with that some of them try to standardize form validations which could be a good thing. Although they may make your code validations much streamlined and make your life easier, you might want fine-grained control over how are you going to do the validations yourself and save it in your component state for later use.
We first need to make sure that our input fields are enclosed within form element. Put this inside render function:.
Notice our noValidate attribute being added in form field. If we enable HTML5 validations, we have little control of the look and feel of error messages and where we should put it. We need to make sure that e. Now that we have gone ahead and set our form elements including onSubmit function, we need to add input fields inside of it so that we can start validating user inputs. Note the required attribute here. If we are to validate input forms, we must include this attribute so Constraint API will know that it needs to be validated e.
Input fields should be named accordingly:. This is one necessary step we need to keep in mind so that we can access specific validation flags of that particular element later on. This is how it should look like:. For email, firstname, lastname:.
Tutorial: Intro to React
Another approach is to use Refs from React. Create ErrorValidationLabel function:. And use this inside render function:. Copy-paste this render function inside your component:.
We can further add some styling in our sample form validation using css. Copy-paste this inside your App. If you followed everything correctly so far, this is how your form validation should look like by now including the source code:. There are already lots of great solutions on validating our forms without too much effort.
And this is one of them. Form validations should not be a pain for web developers.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

In a matter of fact it was slow and on Android - unusable, due to no way we could measure content height properly. This tiny piece of code takes your simple html documents and converts into native React Native components. To be honest - it was tested on React Native only, so i have no idea wether it's of any use for web guys. It was written in about 2 hours. Can it be prettier? Does it fit our needs?

This field provides content writers with a WYSIWYG editor where they can define the text as a header or paragraph, make it bold, add links, etc. The Title field is a specific Rich Text field used for titles. It is also assumed that you have imported a Link Resolver with the variable name linkResolver. To learn more about this, check out the Link Resolving page.
This is necessary to provide the correct url for any Link to a Document that exists in your Rich Text content. Note that you do not need to provide a Link Resolver. Here is an example that outputs the Rich Text content as plain text. If you're using version 1. It works similarly to RichText. You can still use the render method if you prefer to, but we recommend this improved approach.
In that case, the linkResolver will be used to provide the correct url to your internal documents. If you want to handle any Link to a Document that may be present within the Rich Text field being rendered, not just as a hyperlink, but as a particular component, we provide the optional property serializeHyperlink. To use it, you need to pass a function that defines how to create the custom Link component, depending on your needs.
As you can see, the JSX code is much easier to read. React is based on components and states. This is what makes React such a popular library. When you want to create an application, you usually break it into simpler parts.
When programming with React, you will want to break your interface into its most basic parts, and those will be your React components.
Components are wonderful because they are modular and reusable. You can take a basic component used in one area of an application and reuse it in others without having to duplicate code. This helps to speed up development.
Components can be nested, so that the most basic components can be grouped into a parent component. For example, if you were to create a home listing interface with React, the top level component would be the home list itself. Within the list, you would have a description of a single home. Within the home component, you would have the address of the home, as well as other small components such as a photo, perhaps a favorite or save button, and a link to view details and a map.
Component states are what give React its name. If we were to have a home listing, any number of things may change in the database. New photos could be added, and a home can be bought and sold. One thing that may change very quickly, however, would be the number of times a home is saved or favorited or liked by a user. The little component that displays the number of saves could update as soon as the person clicks the Save button by updating the state the moment the button is clicked.
Still, this component describes what we do with components and states. You may notice a naming convention right away. Most element names start with a lowercase letter, followed by capitalization. The names of React classes, however, begin with an uppercase letter. We then have the React. The render method is that most-important method that produces the actual output, and is normally placed last in the component.
As you can see, the output depends on the value of two states: saved and numSaves. Save the addition of the string for the render function. You can also see JSX at work in the render method. Well, not exactly. Because we are dealing with states, we need to set an initial state so that the state variables will always be available in the render method without errors.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

Based on the original work of Thomas Beverleyprops to him. As a result, you need to install it yourself. Please follow the plugin's instructions. This component comes with a demo that showcases every feature presented here. It's very useful to keep track of bugs and rendering differences between the different versions of react-native.
It is mandatory to refer to an example of the demo or to provide one when submitting an issue or a pull request for a new feature. Feel free to write more advanced examples and submit a pull-request for it, it will probably be very useful for other users. Just pass an object to the renderers prop with the tag name as the key, an a function as its value, like so :. Your renderers functions receive several arguments that will be very useful to make some very specific rendering.
By default, a custom renderer behaves like a block. Note : the only values for wrapper are Text or View default. If you wish to change this without having to re-write the whole list rendering implementation, you can use the listsPrefixesRenderers prop. You can also combine these styles with your custom renderers. The default style of your custom renderer will be merged to the one from your classesStyles which will also be merged by the style attribute.
Although it might look like it's working at first, the caching logic of react-native makes it impossible for this module to deep check each of your style to properly apply the precedence and priorities of your nested tags' styles. By default, unstyled images will be rendered with their respective height and width without resizing. If you can't set the dimension of each image in your content, you might find the imagesMaxWidth prop useful.
It resizes and keeps proportions your images to a maximum width, ensuring that your images won't overflow out of your viewport. You could subtract a value to it to make a margin.
Please note that if you set width AND height through any mean of styling, imagesMaxWidth will be ignored. Before their dimensions have been properly retrieved, images will temporarily be rendered in px wide squares. You can override this default value with prop imagesInitialDimensions. Images with broken links will render an empty square with a thin border, similar to what safari renders in a webview. They both are functions that receive the parsed node as their first and only parameter.
