hx_post='/', target_id='tgt', id='frm') | ||
``` | ||
|

``` html | ||
<form hx-post="/" hx-target="#tgt" id="frm" name="frm"><button hx-target="#foo" id="btn" name="btn"></button></form> | ||

|
||
### fill_form | ||
|
||
> fill_form (form:fastcore.xml.FT, obj) | ||
*Fills named items in `form` using attributes in `obj`* | ||
|
||
``` python | ||
@dataclass | ||
class TodoItem: | ||
title:str; id:int; done:bool; details:str; opt:str='a' | ||
|
||
todo = TodoItem(id=2, title="Profit", done=True, details="Details", opt='b') | ||

form = fill_form(form, todo) | ||
assert '<textarea id="details" name="details">Details</textarea>' in to_xml(form) | ||
form | ||
``` | ||
|
||
``` html | ||
<form><fieldset name="stuff"> <input value="Profit" id="title" class="char" name="title"> | ||
<label class="px-2"> <input type="checkbox" name="done" data-foo="bar" class="checkboxer" checked="1"> | ||

### fill_dataclass | ||
|
||
> fill_dataclass (src, dest) | ||
*Modifies dataclass in-place and returns it* | ||
|
||
``` python | ||
nt = TodoItem('', 0, False, '') | ||
fill_dataclass(todo, nt) | ||
nt | ||
``` | ||
|
||
TodoItem(title='Profit', id=2, done=True, details='Details', opt='b') | ||

### find_inputs | ||
|
||
> find_inputs (e, tags='input', **kw) | ||
*Recursively find all elements in `e` with `tags` and attrs matching | ||

inps | ||
``` | ||
|
||
[input((),{'value': 'Profit', 'id': 'title', 'class': 'char', 'name': 'title'})] | ||
|
||
You can also use lxml for more sophisticated searching: | ||
|
||
``` python | ||
elem = lx.fromstring(to_xml(form)) | ||
test_eq(elem.xpath("//input[@id='title']/@value"), ['Profit']) | ||
``` | ||

### sse_message | ||
|
||
> sse_message (elm, event='message') | ||
*Convert element `elm` into a format suitable for SSE streaming* | ||
|

``` python | ||
print(sse_message(Div(P('hi'), P('there')))) | ||
