QUESTION
I am making the Recipe Box project from Free Code Camp. I have an event handler that is supposed to send an object that contains an array property made up of ingredients up to a parent component which will display the items in the array. The problem is, when I first click the button that fires the handler, it sends an empty array even though there are ingredients entered by the user, and the second time I click it, it sends the ingredients from the previous button click, and it goes on like this every time the button is clicked. How can I fix this?

. I'm not sure about all that you're trying to achieve in this method, but a start is:

QUESTION
I have a custom input component and if I pass a prop called value then it is not rendering at all, whereas if I change the name of the prop to something other than value then everything is working as expected. I am trying to figure it out for the past several hours but it was fruitless.
...ANSWER
Answered 2018-Jan-31 at 15:30That's because when you call extractStateFromProps
you are returning a string and a local component state must be set to an object
or null
or undefined
never as a simple value
So when you pass the text

QUESTION
** This may be a simple answer, I'm new to React, thank you for any help ! **
Back storyI have a modal(bootstrap4) hidden inside the main app
with a form inside that, when it rendered, the form is filled out based on the information from the selected recipe (more on that later.)
The recipes are stored locally and with this.state.currentRecipe
I know which recipe is being selected (it is used as the index and is set to 0 by default.)
So, using this.state.currentRecipe
as the index the first render naturally puts in the first recipe's information.
I attempted to solve this by making a function and passing it down the child components. The recipe-card has all the information and the edit button inside of it. So when the recipe-cards are all rendered by .map()
I pass in their index and the function that was passed down in order to change the state of this.state.currentRecipe
and re-render the DOM with the form having the new information.
Everything loads however, when I click the edit button the modal pops up with the first recipe always. It will even change this.state.currentRecipe
but the DOM doesn't re-render with the proper recipe's information.
(and even if it did, would it just hide the modal again?)

I'm trying to implement in my

The recipe is still not added to the list.

What do I need to fix in these components?

ANSWER
Answered 2017-Oct-09 at 10:43In my opinion the onSubmit function is not being invoked.
- The button on the form must be
type="submit"
- You should bind onSubmit function to current scope, in the constructor with
this.onSubmit = this.onSubmit.bind(this)

is a function not a class. You can access the handler as props.handleDeleteAll
and not this.props.handleDeleteAll

QUESTION
I'm doing something similar. I have a recipe blog and I will have different categories such as breakfast, dessert, lunch, etc... But I don't know how to link them the category pages. For example, If the users click "see all" for the breakfast category, it will show all breakfast post from the breakfast category. So that means it will link to the main breakfast category page. For each category i will show 10 recent post so the users is not seeing all post. So they have the option to see all the post if they click the "see all" link. It will link them to the main category page with all breakfast post. Of course if they click the dessert "see all" link, it will link them to the dessert category page which they can see all dessert posts.
This is my current code: (but what php code should i put for the "see all" link? IF you take a look at my "see all" a tag, it's # right now. It's not linking to somewhere, but how do i make it dynamic to link to the categories pages. So for example if i'm in the dessert section, if i click "see all" it will link to the dessert category. )

QUESTION
I have a recipe creator that creates recipes and also lists their ingredients. I want it to only show the Recipe name and it's div it's inside of, but when you click it, it reveals the ingredients section. If any other sections are open I want it to also close them.
I've tried a couple solutions with state but haven't come up with a solid solution. I could probably do it with jQuery but I've heard it's not good practice to use React and jQuery so I'd rather do it properly.
This is the full app: https://github.com/jeffm64/recipe-box2/tree/master/src/components
The recipe boxes are rendered through .map in the main app render function as shown here:
...ANSWER
Answered 2017-Apr-19 at 14:49Revealing just the one component's ingredients will be easier. Closing the rest will be a little trickier.
Revealing ingredients - Without Redux, you could add a state property isOpen
. When you click on a button in that component it should change the state property isOpen
to true. Hide/show the ingredients based on that state property value, which you can do in the markup (shown below) or with a class and a CSS rule.
