Get_element value for checkbox

thomthom

what is the value it returns?

I'm not quite sure, but...
checkbox values are a bit quirky crossbrowsers - might need some help of a javascript to determine the state and return a corresponding value.

But knowing the return value you get from .get_element_value will help.

@@testwindow.get_element_value("test") on @@testwindow.get_element_value("test") on

first one is with checkbox checked, second one without ckeckbox checked......

I do have a suspicion that checkboxes doesn't report a value that reflect the checked state. So you might want to make a JS function that reads the checked state of the checkbox and put it into a hidden input field.

so you first call that JS script using .execute_script - giving the JS function the element id as argument. then read the value of the hidden input field.

Great idea!
Thanks for your helpfull and quick responses

or maybe like this

ruby

command = "_getcheckboxvalue()"
webdialog.execute_script(command)

javascript

function _getcheckboxvalue(){
//get the checkboxvalue
thevalue=document.getElementById('test').value;
//send it back to ruby
query = 'skp;_sendcheckboxvalue@'+thevalue;
window.location.href = query;
}

3.ruby

webdialog.add_action_callback("_sendcheckboxvalue") {|webdialog,p|
//p=the checkbox value
//do something
}

(untested)

The reason why I didn't use .add_action_callback calling back from JS to Ruby is that the amount of data might be limited and there are OSX issues with JS to Ruby callbacks.

Hmm this is strange.

When I try to get the checkbox value in the javascript, it's again always on.
The hidden textbox method also doesn't work because I can't seem to set the textbox value. (and if I could, the checkbox would say its always on....)

Any ideas?

In regard to the checkbox value - did you read my link?

Yes I did thank you for that. Played with it for 2 hours but couldn't manage to read the checkbox values in that manner.
The only thing that worked was the getElementById but it still reports the checkbox as on when its not.

You might just try and keep the state of the control in your own Js variable, and then use onclick or onchange events to toggle the variable ON/OFF value.

I do it for 'toggle buttons' such as buttons that collapse / uncollapse a <DIV>.
