Hello Alain and everyone :)
I've experimented with doing form submission via JavaScript, and it's
working well for me, *except* that I've made an edit to *xsltforms.js*. So
I'd like to show my use case, and show the edit I made to the code, and
then get some feedback.
*1. MY USE CASE*
For now, I find it most convenient to handle the submission in JavaScript.
If submission fails, the server (in my application) will provide a JSON
response containing an exception. I find it simplest (for now) to handle
the submission request in JavaScript (with jQuery which is running in the
parent document). Xsltforms provides for doing this, but I ran into a
problem where it was appending url-encoded instance data to the URL, which
wasn't appropriate in my use case.
Here's the submission element from my form:
<xf:submission
id='submit'
method='get'
relevant='true'
replace='instance'
serialization='application/xml'
action='javascript:submit(ser)'
/>
Here you can see the whole top level of my form, which includes the
JavaScript for submission: http://pastebin.com/N2KCAT5t
*2. MY CODE CHANGE*
*
*
At revision 565, my change is to line 4105 of *xsltforms.js* (split onto
multiple lines here)*:*
if ((method === "get" || method === "delete")
&& this.serialization !== "none"
*&& action.substr(0, 11) !== 'javascript:'*
&& action.substr(0, 9) !== "opener://"
&& action.substr(0, 8) !== "local://") {
The effect of the change is to skip adding the url-encoded arguments, for a
'get' or 'delete' submission where the action is JavaScript. This way I
can pass XML to my JavaScript submission function, and avoid having the
action mangled to something like 'javascript:submit(ser)*
?var1=val1&var2=val2*'.
*3. YOUR THOUGHTS?*
*
*
Is my change OK to integrate into mainline source? Or maybe there's a
better way to go?
Thanks very much,
/Adam
