Best method to add HTML dynamically

[listerofsmeg01]

Hi all,

New to Javascript, and want to learn to do things the RIGHT way.

I have a dynamic table which is populated using Javascript. Currently I
am looking at adding nodes using the W3C DOM, but these seems pretty
long winded, especially adding all the attributes etc.

Is there a way to just blat in a lump of HTML text, or is this frowned
upon now?

Cheers,
Lister

Use DynWrite as in the group FAQ.

DynWrite is based on innerHTML, which is not the best way to modify
tables. It is OK when used to write an entire table, or the contents of
a cell, but it should never be used for the components of a table
(tableSection, tableRow, etc.).
For the OP:

insertRow and insertCell are quite efficient ways to add elements to a
table. Using CSS to style them can save on table-building code. You
might also find it suitable to clone entire rows, then modify the
content of cells.

I see that innerHTML is an MS extension. Is there sufficient cross
browser support to warrent using it?

Out of interest, why shouldn't it be used for tables?

Well I'm afraid I got so hung up on "not using tables for layout", that
I created this particular table using CSS, even though it is a
perfectly valid table - d'oh!
Is InnerHTML OK in this instance?

Many thanks,

lost url to your page

innerHTML would have to be use only with what is between tags (between
onening and closind)

Example of malfunction :

A work about adding row(s) to a table,
I don't know if it is correct with IE :

Then the FAQ needs an update. DynWrite uses .innerHTML, which is surely
not a good thing to be encouraging in new code.

The "right" way is to use the DOM methods, even though they're
long-winded. Wrap them up as needed to keep the coding effort down.

Using innerHTML on table row or section elements will cause errors in IE
at least. Microsoft's documentation says:

"To change the contents of the table, tFoot, tHead, and tr
elements, use the table object model described in How to
Build Tables Dynamically."

It has nothing to do with what you use tables for, only how you modify
them (innerHTML is just a property, it can't differentiate whether the
table is being used for tabular data or just layout). :-)
