a+=b
a=a+b
The expressions are equivalent, and are core javascript (part of the
language itself). The DOM is part of the browser, the DOM exposes
objects to javascript. (document, window etc.)
What I offered is a quick (and dirty) way of using js to write HTML. If
you are interested in the BIG picture, you need to familiarise yourself
with programming concepts - functions, parameters, scope, iteration etc.
The case that you present -stuffing array values into table cells- is
trivial, thus I offered a one-off solution.
I would approach the coding quite differently. I would look for a
*generic* way to accomplish the task at hand:
function stuffArrayValuesIntoTable(array,tableID){
//do stuff here
}
I try to avoid "document.write()" if I can, in favour of DOM techniques.
function stuffArrayValuesIntoTable(array,tableID){
if(!tableID){
// create a table
}
else{
var theTable;
if(theTable=document.getElementById(tableID)){//Table exists
if(array.length>0){//"array" looks like an Array
//do stuff with the table and array
}
}
else{//Flaky ID, or non-DOM browser
return;//exit function
}
}
