I`ve trouble on have a HTML document after onchange function by Nokogiri.
Of course, Mechanize lib can control that. but, sadly webpage which I want to control is jsp not HTML.
Generated HTML showes as belows :
form method = "post" name = "mysearchform"
<select id = "hall_no" name = "hall_no" onchange = "document.mysearchform.submit()">
<option value="1" selected=""> 1 </option>
<option value="2"> 2 </option>
</select>
/form
I guess I POST some data by some command, but Im newbie to Ruby and I cant find any solution about that.
Is there anybody who`ve know about that?
You can't. Nokogiri is a HTML parser and can not execute javascript. Go for something like Capybara with a driver that supports javascript.

Here is my code.
PHP CODE
$smarty->assign('myOptions', array(
1800 => 'ABC',
9904 => 'DEF',
2003 => 'GHI')
);
$smarty->assign('mySelect', 9904);
SMARTY CODE
{html_options name=foo options=$myOptions selected=$mySelect}
DESIRED HTML OUTPUT
<select name="foo">
<option value="1800" title="ABC">ABC</option>
<option value="9904" title="DEF" selected>DEF</option>
<option value="2003" title="GHI">GHI</option>
</select>
You can't; not with the default html_options function at least. You can try to modify it or better create your own plugin to allow more parameters or complex arrays, but other than that, the best way to do it is generating the list of options in the template using a foreach.
Another option would be to use javascript to add the title attribute to each <option> for this or all selects once the page has been loaded.
I have a working dropdown menu, and I can send its value to a function using "submit" button. It's quite clumsy however, as user always has to press the button, wait for the page to load and it refreshes the page so the user loses all other "settings" made on the page. I have understood that ajax would be the solution for this. I read the guide: http://www.web2py.com/books/default/chapter/29/11/jquery-and-ajax#The-ajax-function and tried a few methods, but it never works.
So this is my original working code. Some contents are stripped and altered, but the basics are the same. View demo.html:
<form action="change_dropdown">
<select name="tables">
<option value="first_value">first</option>
<option value="second_value">second</option>
<option value="third_value">third</option>
</select>
<br><br>
<input type="submit">
</form>
Action:
def change_dropdown():
if request.vars.tables:
session.tables = request.vars.tables
else:
session.tables = None
session.main_warning= "Incorrect parameters for function: 'change_dropdown()'."
redirect(URL('demo'))
return
Then the original action demo does something with session.tables and so on. But now about turning it to ajax. This is what I want:
<form>
<select name="tables", onchange="ajax('change_dropdown', [], '');">
<option value="first_value">first</option>
<option value="second_value">second</option>
<option value="third_value">third</option>
</select>
</form>
I also did this to the action: redirect(URL('demo'), client_side=True) as mentioned in an example. I have no idea why it's needed however.
But I don't know how to send the variable tables to the action. If I write it inside python URL helper, it crashes, because it thinks it's a python variable (where it's actually a JavaScript variable (?)). If I write it inside ajax() function's second parameter, it halts and gives me a weird error in JS console:
Uncaught Error: Syntax error, unrecognized expression: [name=[object HTMLSelectElement]]
If you need more information I can show you full codes for the methods I tried, but I think someone can take it from here.
You can send the variable as follows:
ajax("{{=URL('change_dropdown')}}",['tables'],':eval')
redirect(URL('demo'), client_side=True) is needed as you want to redirect the function that have sent the ajax request to redirect not 'change_dropdown' to redirect.
EDIT:
<form>
<select name="tables", onchange="ajax(\"{{=URL('change_dropdown')}}\",['tables'],':eval') ;">
<option value="first_value">first</option>
<option value="second_value">second</option>
<option value="third_value">third</option>
</select>
</form>
Is it possible to use multiselect boxes on Codeception?
My form code:
<form accept-charset="utf-8" class="form-vertical" id="solicitor-form" method="POST" action="http://mytest.dev/role">
<select multiple="true" id="optgroup" name="solicitor[]">
<option value="1" selected>Yorkshire</option>
<option value="2" selected>Quarry</option>
<option value="3" selected>William Hurst</option>
</select></div></div>
<input class="btn-large btn-success btn" type="submit" value="Update Access">
</form>
I've tried something like this for the test:
$i->SeeOptionIsSelected("#solicitor-form", 'Yorkshire');
$i->SeeOptionIsSelected("#solicitor-form", 'Quarry');
But codeception fails on SECOND select. So then I tried this:
$i->SeeOptionIsSelected('#solicitor-form select[name=solicitor[]]', 'Yorkshire');
$i->SeeOptionIsSelected('#solicitor-form select[name=solicitor[]]', 'Quarry');
but it doesnt seem to resolve solicitor[] correctly, specifically the [] because it trips itself up with the pattern match.
Edit: I tried Daverts answer like this:
$i->selectOption('optgroup',array('Quarry', 'Yorkshire'));
But this is the output when running the test:
* I select option "optgroup","lambda function"
It seems the "lambda function" is not returning the correct result?
Sorry for a delay.
It looks like this feature was not documented. Sorry, I totally forgot to update docs, when released 1.6.3.
You can pass an array of options as a second parameter to select multiple options.
$I->amOnPage('/form/select_multiple');
$I->selectOption('What do you like the most?',array('Play Video Games', 'Have Sex'));
$I->click('Submit');
Thanks, I will update a reference soon.
The bug is exactly with [] as far as I can see in my application, for example I have this select:
<select multiple="true" class="span h300" id="products[]" name="products[]">...</select>
and when I do:
$I->selectOption('Products', array('value', 'someOtherValue') );
I'll get the same error as you do.
As you can see I have some additional classes, .span and .h300 so I've used .h300 selector which is unique on that page and the test works perfectly, the values are in db and verification works as expected...
So to sum it up my selector which works is:
$I->selectOption('.h300', array('value', 'someOtherValue') );
Just my 2 cents on the issue, don't have enough time now to investigate what causes the problem with []...
How to write Ajax code to retrieve information on to a particular part of webpage when we select option from a dropdown box?
I want information of a particular item that I had selected from a dropdown menu on particular part of my webpage.
Let's say your markup looks something like:
<select id="dropdown">
<option value="1">Some option</option>
<option value="2">Other option</option>
<option value="3">Helpfull option</option>
<option value="4">Don't pick this option</option>
</select>
<div id="details"></div>
In order to make AJAX calls I would use some sort of library. Using for instance jQuery will be much easier than writing code that handles ajax calls across different browsers. The code could look like this:
$('#dropdown').on('change', function(e) {
var currentValue = $('#dropdown').val();
$.get('<someurl>', function(data) {
$('#details').html(data);
});
};
Replace '<someurl>' with the url to the resource you want. Doing this without using jQuery or similar library is a bit more involved. For some guidance you can look at this answer: https://stackoverflow.com/a/2557268/355499
I have a simple form where there is a list:
<form method ="post" action ="">
<select>Select subject
<option value="1">Maths</option>
<option value="2">Science</option>
</select>
<input type="submit" name="Submit" />
My question is, if I select the option Maths, I would like the value to be sent eg /1.
What should be written in action? How should the route be written ?
get '' do
end
Your route could look something like this:
post '/subject' do
#subject = params[:subject]
# do whatever you want now
end
But you would need to give your select tag a name and your form an action:
<form method="post" action="/subject">
<select name="subject">
<!-- etc etc -->
Also have a look at related questions.
we tend to look at queries as GETs (makes sense, it is after all retrieving information)
rather than a POST which (doesn't actually change data) yet responds with a result page
a common (gnarly) pattern we often see is to rewrite (in js or redirect)
to the form
GET '/search/:q1/and/:q2' do
// result of search filtered by q1 and q2
end
which is also quite neat
