How to run an action for every item in a list?

Question

I have a list of items. For every item in the list, i want to run an html code.
For example for item in list
Make a list with the value of the item
That means if there are 6 items in an array, the html to make a <li> will be executed 6 times, any way to make this?

Answer 1

This way if I understand the question right

window.onload=function(){
a=["spam","eggs"]
for(i in a){
if(i<a.length){
var b=document.createElement("li");
var c=document.querySelector("body");
c.appendChild(b);
b.innerHTML=a[i];

}
}
}

Answer 3

Thanks,i was just looking at stack flow answers and got reminded why I used to get length in ouput when I used for i in ,as it iterates over the keys of an object

Answer 4

Abhay Can you explain why you used "for (i in a)" and "if (i<a.length)", please? I read that using for ... in is not good for iterating over arrays.

My version (adopted from yours):

let a = ["spam", "eggs"];
for (i of a) {
var b=...
...
b.innerHTML=i
}
