Hello,
A custom portlet has a form with select tag.
There is a "submit" button right now to select the value which works fine,
but now I want to have same effect without submit button.
I used onchange="this.form.submit()" without success.
Can somebody point out what am I doing wrong?
The form:
<form method="post"
tal:attributes="action view/current_url">
<div class="portletContent">
<select name="currency_code" id="currency_code"
onchange="this.form.submit()">
<tal:block tal:repeat="cnc view/currency_code_and_name_list"
tal:define="sc view/sc_code">
<option value="None"
tal:content="cnc/name"
tal:attributes="value cnc/code;
selected python: cnc['code'] == sc">
</option>
</tal:block>
</select>
<noscript>
<input class="standalone"
type="submit"
id="form.button.Update"
value="Update"
name="form.button.Update"
i18n:attributes="value"/>
</noscript>
</div>
</form>
Class:
class Renderer(base.Renderer):
render = ViewPageTemplateFile('
currency_info.pt')
def update(self):
super(Renderer, self).update()
## Defines.
form = self.request.form
context = aq_inner(self.context)
sdm = getToolByName(context, "session_data_manager")
session = sdm.getSessionData(create=True)
## Check buttons.
update_button = form.get('form.button.Update', None) is not None
if update_button:
session.set('selected_currency_code', form.get('currency_code'))
return self.render()
def current_url(self):
"""Returns current url"""
context= aq_inner(self.context)
context_state = self.context.restrictedTraverse("@@plone_context_state")
url = context_state.current_page_url()
return '%s' % (url,)
