Creating Repetition Rows Dynamically

[bobhaugen]

I want to add new repetition rows to a template from client-side
javascript.

I looked at Test Case 20: Creating Repetition Templates Dynamically
http://webforms2.googlecode.com/svn/trunk/testsuite/020.html

It does not seem to work, and a bunch of the source is commented
out.

I am not sure it is relevant to what I want to do anyway, but its
failure prompted this message.

I'm looking into addRepetitionBlock() and will do some experiments,
but some guidance and/or an example would be nice.

Will report back if I get something to work.

Cheers,
Bob

I haven't yet programmed the functionality to create repetition templates dynamically. I added that test case to demonstrate what cannot yet be done but what should be able to be done. Note that the test case fails with Opera's native implementation, so obviously, creating repetition templates is not well supported.

Any reason I cdn't call addRepetitionBlock() from my own code?

I mean, when you write that you "haven't yet programmed the
functionality to create repetition templates dynamically", do you mean
just creating templates, or also adding rows to existing templates?

In this situation, I am happy to create the template statically, I
just want to add rows dynamically based on a user selection of the
parent object for the child rows.

Or am I going up a blind alley and shd just roll my own entry tables
in this case?

Looks like it works a charm. Maybe I'll run into some hidden rocks,
but so far so good.

Oh, right, I mean creating repetition templates dynamically, not creating blocks dynamically. To do the latter, simply call addRepetitionBlock as you mentioned. Thanks for pointing that out.

Here's my current test code, which appears to work. Any suggestions
for improvement? A better way to get all the blocks for removal?

function addRow()
{
var template=dojo.byId("order");
template.addRepetitionBlock();

}

function removeAllRows()
{
var orders=dojo.html.getElementsByClass("order");
for(var i=0;i<orders.length;i++)
{
var orderItem=orders[i];
if(orderItem.repetitionType==RepetitionElement.REPETITION_BLOCK)
{
orderItem.removeRepetitionBlock();
}
}
}

You can use the "repetitionBlocks" property on the repetition template element:

function removeAllRows(){
    var template=dojo.byId("order");
    while(template.repetitionBlocks.length){
        template.repetitionBlocks[0].removeRepetitionBlock();

Cool! Much cleaner.
