Displaying array with innerHTML


Recommended Posts

My code is a mess from various attempts at a simple task (it is embarrassing). And also frustrating (especially since my searching hasn't found a solution, or a more important explanation of WHY a method works).

I want to have my stay contents displayed in a specific HTML container.


fruits = ["apple", "orange", "cherry"];

x = document.getElementById("myList").innerHTML;

for (x = 0; x< fruits. length; x++){
document.getElementById("demo").innerHTML = x;

I need a solution. And would appreciate comments for educational understanding.

Here's what your code is attempting to do. Does it look anything like what you intended?

    fruits = ["apple", "orange", "cherry"];               // define an array of fruits

    x = document.getElementById("myList").innerHTML;      // get text content from mylist and put in x 
                                                          // (I have no idea how this relates to rest of the code)

    for (x = 0; x< fruits.length; x++) {                  // now use x as a counter to loop throught fruits array
                                                          // (whatever you put in x above is now replaced by the counter values)
        document.getElementById("demo").innerHTML = x     // each time through the loop put the value of x (0,1,2) into demo
                                                          // so, at the end of the loop, demo should have value of 2.

Copied a wrong line.

But still...

fruits = ["apple", "orange", "cherry"];

for (x = 0; x< fruits.length; x++){
document.getElementById("demo").innerHTML = fruits[x];

What would get this working?

Would for each be any better?

What is HTML markup for that page? Then we can get an idea of what you are trying to do.

Do you realize you can only use an id once - they have to be unique?

The first time throught the loop will put apple into demo. The second time will overwrite apple with orange. Finallly you will finish with just cherry in the demo element.
