Question

:) I hope that you are all well.

I am currently doing a Full Stack Web Development course and am new in the Javascript world. I am quite stuck at the following assignment question: "Whenever a user clicks on an image of a car, the showMore() method should be called and all the information about the car, including the registration number, price etc. should be displayed".

I have tried the following:

imgProfile.onClick function = { carButton.innerHTML = "car.showMore()" }

image.onclick = function (showMore){ showMore(); }

I have also tried to bind the two together, but nothing seems to work.

 /* CREATED FUNCTIONAL CONSTRUCTOR */ function CarDescription(make, model, colour, image, registration, price) { this.make = make; this.model = model; this.colour = colour; this.image = image; this.registration = registration; this.price = price; } /* POPULATED/ SET PROPERTIES OF THE CARS */ let car1 = new CarDescription( "Chevrolet", "Coupe", "Tan Brown", "images/Chevrolet.png", "DL 24 23", "R 795 000.00" ); let car2 = new CarDescription( "Renault", "NN1", "Green", "images/Renault.png", "DH 48 70", "R 645 000.00" ); let car3 = new CarDescription( "Peugeot", "203 Pick-up", "Red", "images/Peugeot.png", "OAS 905", "R 575 000.00" ); let car4 = new CarDescription( "Packard", "One Twenty", "Yellow", "images/Packard.png", "NT 5235 PO", "R 685 000.00" ); let car5 = new CarDescription( "Volga", "Gaz-21", "Black", "images/Volga.png", "AX 0210 BP", "R 565 000.00" ); /* CREATED CAR ARRAY */ let myCars = [car1, car2, car3, car4, car5]; /* CREATED FUNCTION TO SHOW CARS WHEN PAGE IS LOADED */ let loaded = {}; loaded.addCars = function () { /* FOR EACH METHOD USED TO LOOP THROUGH ARRAY */ myCars.forEach(function(car) { /* INFORMATION TO BE LOADED TO <DIV> ELEMENT IN HTML */ let div = document.getElementById("carDetails"); /* CREATED IMAGE ELEMENT AND SET THE PROPERTIES */ let imgProfile = document.createElement("img"); imgProfile.src = car.image; imgProfile.alt = car.make + " " + car.model; imgProfile.style.height = "320px"; imgProfile.style.width = "480px"; /* CAR MAKE AND MODEL SET TO DISPLAY AS HEADING */ let carName = document.createElement('h2'); carName.innerHTML = car.make + " " + car.model; /* SHOWMORE BUTTON CREATED */ let carButton = document.createElement("button"); carButton.innerHTML = "Show More"; /* CREATED DIALOG TO DISPLAY INFORMATION */ let carDialog = document.createElement("dialog"); let dialogInfo = document.createTextNode("Colour: " + car.colour + ", Registration: " + car.registration + ", Price: " + car.price); carDialog.appendChild(dialogInfo); /* DIALOG ATTACHED TO CAR OBJECT */ car.dialog = carDialog; /* SET DIALOG OPEN PROPERTIES */ car.showMore = function () { myCars.forEach(function (curr) { curr.dialog.removeAttribute("open"); }) car.dialog.setAttribute("open", "open"); }; carButton.addEventListener("click", function (e) { car.showMore(); }); let lineBreak = document.createElement("div"); lineBreak.classList.add("spacer") /* ELEMENTS APPENDED TO PARENT DIV */ div.appendChild(imgProfile); div.appendChild(carName); div.appendChild(carButton); div.appendChild(carDialog); div.appendChild(lineBreak); }); }; loaded.addCars();

I would appreciate it if someone can help me onto the right track.

Answer 1

I think that you need to do the following thing:

imgProfile.onclick = function showMore(event) {
        car.showMore()
}

You can do this too:

imgProfile.onclick = (event)=>{
        car.showMore()
}

Hope that could help you!
