[Mechanize-users] following a javascript link that unhides a field ... quick workaround?
I am using Mechanize for the first time, and have gone through a login page
and a couple of links. But I am now attempting to click a javascript link.
The link unhides a div that has three fields in it. And Mechanize throws an
error when I hit this javascript link.
Here is html of the javascript link....
<a id="_ctl20_hlAvgrensRevisor" class="AdvanceSearchLink"
onclick="if (
document.getElementById(''_ctl20_hiddenRevisor'').value ==
''none'') {
document.getElementById(''_ctl20_DivRevisor'').style[''display'']
= '''';
document.getElementById(''_ctl20_hiddenRevisor'').value =
''''; } else {
document.getElementById(''_ctl20_DivRevisor'').style[''display'']
= ''none'';
document.getElementById(''_ctl20_hiddenRevisor'').value =
''none''; }"
href="javascript:;">Avgrens p?
Revisor/Regnskapsf?rer</a><input
name="_ctl20:hiddenRevisor" type="hidden"
id="_ctl20_hiddenRevisor"
value="none" />
...which shows up like this in Mechanize....
#<Mechanize::Page::Link "Avgrens p? Revisor/Regnskapsf?rer"
"javascript:;">
...and then I click it like this and get the following error...
>> agent.page.link_with(:text => /Avgrens p? Revisor.*/).click

...Oh, and here''s what the hidden div looks like...
<div id="_ctl20_DivRevisor" style="display:

<table id="TableRev" cellspacing="0"
cellpadding="1"
width="100%" border="0">
<tbody>
<tr>
<td nowrap>
Organisasjonsnummer revisor:</td>
<td width="100%">
<input
name="_ctl20:txtRevisorOrgnr"
type="text" maxlength="9"
id="_ctl20_txtRevisorOrgnr" class="stor" />
<span
controltovalidate="_ctl20_txtRevisorOrgnr" errormessage="Avgrens

id="_ctl20_rvOrgnr"

validationexpression="\d{9}"
style="color:Red;display:none;">M? v?re 9
siffer uten mellomrom!</span>
</td>
</tr>
<tr>
<td nowrap>
Organisasjonsnummer
regnskapsf?rer:</td>
<td width="100%">
<input
name="_ctl20:txtRegnskForerOrgnr"
type="text" maxlength="9"
id="_ctl20_txtRegnskForerOrgnr" class="stor"
/>
<span
controltovalidate="_ctl20_txtRegnskForerOrgnr"
errormessage="Avgrens p?

display="Dynamic"
id="_ctl20_rvOrgnrRegnskapsforer"
evaluationfunction="RegularExpressionValidatorEvaluateIsValid"
validationexpression="\d{9}"
style="color:Red;display:none;">M? v?re 9

</td>
</tr>
<tr>
<td>
Navn regnskapsf?rer:</td>
<td>
<input
name="_ctl20:txtRegnskForer"
type="text" id="_ctl20_txtRegnskForer"
class="stor" /> firmanavn
eller personnavn (etternavn fornavn
mellomnavn)
</td>
</tr>
</tbody>
</table>
</div>
... So it looks like everything I need should be here. I have to believe
that there must be manual way for me to ''give'' Mechanize what
it needs to be
able to build it''s internal model with these three fields. How should
I
proceed?

[Mechanize-users] following a javascript link that unhides a field ... quick workaround?
Mechanize can''t parse JavaScript. Look into using Harmony. Oh, and good luck!
