Hello fellow Heavylifters,
the following small utility classes could be useful for those who
develop somewhat classic data-oriented applications in Lift and with
Mapper:

In short:
* Do more with less template and snippet code
* Only execute the parts
Very cool!

Why are you specifying some by name and some by id? Do not use name. SHtml.text
works by using an autogenerated name.
If you're doing id and it doesn't work, does, say 'size' work?

That's you're problem. SHtml.text needs to set name to its own autogenerated
value.
If you need a custom name then you have to handle processing it manually.
Use S.param in e.g. the SHtml.submit callback to read the query params. For
example, S.param(text1) returns a Box that is Full if the URL or
I got your point this makes sense and can be the cause of problem i am
facing.
but i have one more doubt as for example my use case of application is

submit button ,
You can get query params with JavaScript with something like:
var url = window.location.toString();
and then split it up ... if that is what you're looking for.

attributes specified in your markup and not put then from scala you

hi Naftoli

text2 - SHtml.text(text2,text2 = _),
result -SHtml.text(result, result = _, ),
submit -
You're surrounding the input tag with the form:text1 element?
If you look at View Source in the browser you'll see that the output of
SHtml.text does not include your input tag, but uses its own.
The simplest solution is to put your custom attributes in the scala code:
SHtml.text(text1, text1 =

If you were going to do that I would suggest a hybrid approach. Use regular
HTML input tags for the submit in your form in the template and make your
last bound function execute the form processing function. So the template
could look like:
lift:My.snippet form=POST
input type=submit value=Hit
I just had another idea. You could add a guard field in your form using
SHtml.hidden and have it set a var to true:
var doForm = false
bind(...
guard - SHtml.hidden(() = doForm = true),
submit - SHtml.submit(...))
Then the submission function *would* get called twice, but you could
Or a third idea. Use a hidden to execute your processing function. From the

lift:My.snippet form=POST
input type=submit value=Hit Me! /

/lift:My.snippet
