QUESTION
So I have two .js files (are they also called modules?). The first .js file is a class-based component. It has handleClick()
as well as render()
. It looks like this (I've actually removed a lot of the code to make it appear shorter here):
ANSWER
Answered 2021-Mar-03 at 17:38In your upper component, you need to replace the onClick
property with a handleClick
property.
QUESTION
I am building a rock/paper/scissors React app, but I am having problems when I try to make a choice (rock, scissors or paper), save the value of that choice and display it in the screen. I have managed to console.log all the values of the user selected choice, but I don't know how to pass them back to my Choice component, and actually see it on the screen.
Could you please help me resolving this issue ?
Thanks a lot!

Move the individual images into an object called images:
QUESTION
function calc_results(){
var scores = [0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0];
for (var StatementCounter = 0; StatementCounter < 29; StatementCounter++){ // 29 statements it loops trough
for (var positionCheck = 0; positionCheck < 23; positionCheck++){ // 23 parties it loops through
if(choices[StatementCounter] == subjects[StatementCounter].parties[positionCheck].position){ // if my choice is the same as the party's choice
var partyposition = getpartyposition(subjects[StatementCounter].parties[positionCheck].name);
scores[partyposition]++;
}
}
}
}
function getpartyposition(partyname){
for (var positionCheck = 0; positionCheck < 23; positionCheck++){
if(parties[positionCheck].name == partyname){
return positionCheck;
}
}
}
// these are the parties that are already connected to the string, there are actually 23 of them.
var parties = [{
name: "VVD",
},
{
name: "CDA",
},
{
name: "PVV",
}
...ANSWER
Answered 2020-Jul-04 at 10:00Scores is an array of int so just doing score[0].toString
will work.
But parties is an array of object. You need to do something like this, parties[0].name
. No need to to do a toString since it's already a string.

UPDATE: Using the code from u/kinduser this is where I'm at

logic into your child component.
QUESTION
I have the following code which works fine except that my lifecycle method componentWillLoad() seems not to fire.
(please find componentWillLoad in the middle of second code snippet)
My Code:
1) index.js
...ANSWER
Answered 2018-May-30 at 19:53There is no lifecycle method called componentWillLoad
.
There is instead componentWillMount
/ componentDidMount
.
componentWillMount()
is invoked just before mounting occurs. It is called beforerender()
, therefore callingsetState()
synchronously in this method will not trigger an extra rendering. Generally, we recommend using theconstructor()
instead for initializing state.
Since React 16.3 componentWillMount
is deprecated and you can use componentDidMount
instead.
componentDidMount()
is invoked immediately after a component is mounted. Initialization that requires DOM nodes should go here. If you need to load data from a remote endpoint, this is a good place to instantiate the network request.
QUESTION
I currently have an app where visitors signup through an AJAX form using devise.
I want to enhance this form and do the following:
- When the user is on the page, a modal with a subscription choice appears.
- Once he submits this form, the signup form shows up.
- Once he filled in the form and submitted it, the payment form (+ recap of the chosen subscription) appears.
- Once the user paid, he is redirected.
So I was thinking about three consecutive AJAX calls to do so, but I'm stuck.
Here is what I did for the first part (to get from the subscription choice form to the signup form):

Answered 2018-Aug-29 at 14:31OK so it was actually a router issue.

the routes of subscriptions#index and subscriptions#show were mentionned first:
QUESTION
I have been practicing JavaScript and ReactJs and I have been stuck on a problem for a while. Basically, I am trying to rewrite my HTML, CSS, Javascript project using ReactJs.
Here is my problem: (in regards to the React code). Say I click on the first answer choice for Question 1, the class name changes hence, styling changes(background becomes black) AND isClicked becomes true (both are states inside the EachIndividualAnswer class). If I then click on the second answer choice, I want the style for the first answer choice (and every other answer choice for that question) to be null, and isClicked to be false and ONLY the second answer will have isClicked === true and className="clicked".
Hope this makes sense. Sorry for sending so many files, Didn't know any other way.
Thanks
