just wondering, how can I get the value of a hidden element using watir? This is the element:
<input type="hidden" value="randomstringhere" id="elementid" name="elementname" />
And this is my code atm:
require "rubygems"
require "watir-webdriver"
$browser = Watir::Browser.new :ff
$browser.goto("http://www.site.com")
$grabelement = $browser.hiddens(:id, "elementid")
$blah = $grabelement.attribute_value("value")
puts $blah
This gets stuck at the last line, where it returns
code.rb:6:in `<main>': undefined method `attribute_value' for #<Watir::HiddenCollection:0x8818adc> (NoMethodError)
Sorry for the basic question, I've had a search and couldn't find anything.
Thanks in advance!
Problem
Your code is quite close. The problem is the line:
$grabelement = $browser.hiddens(:id, "elementid")
This line says to get a collection (ie all) of hidden elements that have id "elementid". As the error message says, the collection does not have the attribute_value method. Only elements (ie the objects in the collection) have the method.
Solution (assuming single hidden with matching id)
Assuming that there is only one, you should just get the first match using the hidden instead of hiddens (ie drop the s):
$grabelement = $browser.hidden(:id, "elementid")
$blah = $grabelement.value
puts $blah
#=> "randomstringhere"
Note that for the value attribute, you can just do .value instead of .attribute_value('value').
Solution (if there are multiple hiddens with matching id)
If there actually are multiple, then you can iterate over the collection or just get the first, etc:
#Iterate over each hidden that matches
browser.hiddens(:id, "elementid").each{ |hidden| puts hidden.value }
#Get just the first hidden in the collection
browser.hiddens(:id, "elementid").first.value

I am working on my second Python scraper and keep running into the same problem. I would like to scrape the website shown in the code below. I would like to be ability to input parcel numbers and see if their Property Use Code matches. However, I am not sure if my scraper if finding the correct row in the table. Also, not sure how to use the if statement if the use code is not the 3730.
Any help would be appreciated.
from bs4 import BeautifulSoup
import requests
parcel = input("Parcel Number: ")
web = "https://mcassessor.maricopa.gov/mcs.php?q="
web_page = web+parcel
web_header={'User-Agent':'Mozilla/5.0(Macintosh;IntelMacOSX10_13_2)AppleWebKit/537.36(KHTML,likeGecko)Chrome/63.0.3239.132Safari/537.36'}
response=requests.get(web_page,headers=web_header,timeout=100)
soup=BeautifulSoup(response.content,'html.parser')
table=soup.find("td", class_="Property Use Code" )
first_row=table.find_all("td")[1]
if first_row is '3730':
print (parcel)
else:
print ('N/A')
There's no td with class "Property Use Code" in the html you're looking at - that is the text of a td. If you want to find that row, you can use
td = soup.find('td', text="Property Use Code")
and then, to get the next td in that row, you can use:
otherTd = td.find_next_sibling()
or, of you want them all:
otherTds = td.find_next_siblings()
It's not clear to me what you want to do with the values of these tds, but you'll want to use the text attribute to access them: your first_row is '3730' will always be False, because first_row is a bs4.element.Tag object here and '3730' is a str. You can, however, get useful information from otherTd.text == '3730'.
I'm pretty new to MVC and I'm having a hard understanding how to get the values (basically the IDs) to checkboxes that I'm generating. Here are my checkboxes:
<div id='myCheckboxDiv'>
<input type="checkbox" onclick="checkAll(this)">Check All
#foreach (var form in #Model.DetailObject.DoaFormGroupDocuments)
{
<br>
var checkBoxId = "chk" + form.DocumentId;
#Html.CheckBox(checkBoxId, new { value = form.DocumentId, #checked = true });
#form.DocumentName;
}
</div>
Essentially what I want to do is get the ID to which ever checkbox is checked and save it in to a list after I click a save button at the bottom of the page.
I have run across something like this to handle everything but I'm not quite sure how to use it really...
var values = $('#myCheckboxDiv').find('input:checkbox:checked').map(function () {
// get the name ..
var nameOfSelectedItem = this.attr('name');
// skip the ‘chk’ part and give me the rest
return nameOfSelectedItem.substr(3);
}).get();
The only thing you need to think about is the value of the name attribute your checkbox(es) will have. The way you're handling it right now, your post body is going to have a fairly randomized collection of chkN-named parameters, where N is some number. The modelbinder will need something similarly named as a parameter to your action method in order to bind the posted values to something useful. That's a tall order for something that will be some what variable (the DocumentId values).
The best option would be to set up your checkboxes, instead, as a collection, which means giving them names chk[0], chk[1], etc. Then in your action you can accept a parameter like List<string> chk, and that will contain a list of all the values that were posted.
I am running into a problem with my vbscript code. My HTML code looks like this
<input type='checkbox' name='DisplayRow' id='DisplayRow1' />
<input type='checkbox' name='DisplayRow' id='DisplayRow2' />
<input type='checkbox' name='DisplayRow' id='DisplayRow3' />
This is done because above there is another checkbox that calls a javascript function that will check or uncheck all of the "DisplayRow" checkboxes. The javascript function uses getElementsByName to return all of the checkboxes named "DisplayRow".
When the form's submit button is clicked the action sends it to an ASP page (classic ASP) that grabs all of the objects on the calling form by using the Request.Form command. The Request.Form command looks at the "name" attribute, not the "id" attribute of the object.
This seems to be working fine for all of the other form objects. When it gets to the checkboxes because the "name" attribute uses the same name for all of the check boxes it returns an array. The individual checkboxes can be accessed like this:
Request.Form("DisplayRow")(x)
Where x references the individual checkbox in the array.
If the checkboxes are checked I can loop through the array without any problems. If 1 or more or all of the checkboxes are unchecked then when the code references the first checkbox in the array that is unchecked the page crashes. Nothing is executed after the Request.Form command fails.
I have tried enclosing the Request.Form("DisplayRow")(x) in an IsNull function in an If statement but it still takes the program down.
Has anyone else ran into this and found a work around?
Edit
For some reason stackoverflow is not letting me add more than one comment.
#Cory. Thanks for the information
#jwatts1980. Count works but it does not let me know which of the checkboxes are checked. If the count is greater than 0 I can loop through them but if the first one is unchecked I am right back where I started with a crashed page.
You cannot do it this way because unchecked checkboxes will not be submitted in the post, only the checked ones.
I would approach this differently:
First I would add a value attribute to the checkboxes, as so:
<input type='checkbox' name='DisplayRow' id='DisplayRow1' value="1" />
<input type='checkbox' name='DisplayRow' id='DisplayRow2' value="2" />
<input type='checkbox' name='DisplayRow' id='DisplayRow3' value="3" />
Notice the value is the same as the index, this will be needed in the code.
Next I would use .Split() to gather the checkboxes selected in an array, since the values will come in as a string separated by comma, ie: 1,2,3 to your .Form() value.
Rows = Request.Form("DisplayRow")
'check if any are selected first
If Rows <> "" Then
'make an array with each value selected
aRows = Split(Rows,",")
'loop through your array and do what you want
For i = lBound(aRows) to uBound(aRows)
Response.Write "DisplayRow" & aRows(i) & " was Selected."
Next
End If
This way you only process the results for the one's selected, and ignore the others.
I've always found this essential for my library...
'GetPostData
' Obtains the specified data item from the previous form get or post.
'Usage:
' thisData = GetPostData("itemName", "Alternative Value")
'Parameters:
' dataItem (string) - The data item name that is required.
' nullValue (variant) - What should be returned if there is no value.
'Description:
' This function will obtain the form data irrespective of type (i.e. whether it's a post or a get).
'Revision info:
' v0.1.2 - Inherent bug caused empty values not to be recognised.
' v0.1.1 - Converted the dataItem to a string just in case.
function GetPostData(dataItem, nullVal)
dim rV
'Check the form object to see if it contains any data...
if request.Form = "" then
if request.QueryString = "" then
rV = nullVal
else
if request.QueryString(CStr(dataItem))="" then
rV = CStr(nullVal)
else
rV = request.QueryString(CStr(dataItem))
end if
end if
else
if request.Form(CStr(dataItem)) = "" then
rV = CStr(nullVal)
else
rV = request.Form(CStr(dataItem))
end if
end if
'Return the value...
GetPostData = rV
end function
To use the function you simply pass in the form or query string item you're looking for and what to replace empty values with...
Dim x
x = GetPostData("chkFirstOne", false)
You can keep using your existing code by adding a single condition:
If Request.Form("DisplayRow").Count > 0 Then
'your code here
Else
'consider adding message saying nothing was selected
End If
Using EWS managed api v1.1, I can successfully save/set the contact "Title" or honorific (if you prefer) to a non-empty value, but I can't figure out how to remove or set it back to an empty string/null.
I've tried to set an empty value and I've tried to remove the extended property. Here is relevant code.
var titleDef = new ExtendedPropertyDefinition(0x3A45, MapiPropertyType.String);
// works when set to a non-empty string value
ewsContact.SetExtendedProperty(titleDef, "Mr.");
// throws null argument exception when set to String.Empty or null
ewsContact.SetExtendedProperty(propDefinition, String.Empty);
// isRemoved is equal to false and the value doesn't change
var isRemoved = ewsContact.RemoveExtendedProperty(titleDef);
I've also tried to use a different overload on the ExtendedPropertyDefinition as mentioned in this very similar question, but it didn't change my end result for removing the property. I'm not sure I understand the difference in the two signatures for the constructor.
var titleDef = new ExtendedPropertyDefinition(new Guid("{00062004-0000-0000-C000-000000000046}"), 0x3A45, MapiPropertyType.String);
// isRemoved is equal to false and the value doesn't change
var isRemoved = ewsContact.RemoveExtendedProperty(titleDef);
Brute Force Work-Around
I suppose I could take a complete copy of the contact (without the title) and delete the original, but that seems a bit over the top and would probably cause other bugs.
EWS lets you assign Extended Properties without first binding them. However, to remove an Extended Property - you need to include it in your initial binding call PropertySet. The following worked for me...
var titleDef = new ExtendedPropertyDefinition(0x3A45, MapiPropertyType.String);
Contact contact = Contact.Bind(service, id, new PropertySet(titleDef));
contact.RemoveExtendedProperty(titleDef);
contact.Update(ConflictResolutionMode.AutoResolve);
It is also strange that you can retrieve the Title as a first-class property, but you cannot assign it (since it's a complex type). They could have made this easier for us.
var title = contact.CompleteName.Title;

UPDATE: Perhaps the best way to do this is through HTML or JavaScript(I know nothing of these)?
Objective
After the whole code is run and an output is given, I'd like to provide a hyperlink to re-run the code, with the same search word, but different radio buttons pressed.
Here is a portion of my CGI script, related to the user input:
my $search_key = param('query');
my $c_verb = param('verb_only');
my $c_enabling = param('enabling');
my $c_subject = param('subject');
my $c_object = param('object');
my $c_prep = param('prep');
my $c_adj = param('adjective');
my $c_modnoun = param('modnoun');
my $category_id;
if ($c_verb eq 'on')
{
if ($c_enabling eq 'on')
{$category_id = 'xcomp';}
elsif ($c_subject eq 'on')
{$category_id = 'subj';}
elsif ($c_object eq 'on')
{$category_id = 'obj';}
elsif ($c_prep eq 'on')
{$category_id = 'prep';}
I don't have access to the HTML, but from viewing the source code, all the $c_... have the form:
<input type="checkbox" name="verb_only" onClick="ch...
The "unseen" in the title is referring to no appended name/tag value pairs, so I don't know what to change, Where can I find this information?
I was thinking of changing $c_enabling to $c_subject and another link to a case where it was as if $c_prep was chosen from the user. Is there a way to substitute the name-value pairs of that single param? (So user inputs options, runs, instead of going back to input different ones, just click hyperlink, because some options stay the same)
The URL of the form is like: http://concept.whatever.com/test.html and the output is at the URL: http://concept.whatever.com/cgi-bin/search2011.cgi
My attempt
See posted answer
UPDATE: I've tried `url(-query) but nothing was appended to the end...
Thanks for any advice. Let me know if this is not clear.
Original: http://www.perlmonks.org/?node_id=910616.... Particularly applying this advice: http://www.perlmonks.org/?node_id=910630
If the method of the HTML is changed to GET instead of POST:
<form name="search_option" action="http://localhost/cgi-bin/mytestsearch2011.cgi" method="get">
Then the tags can be viewed (I had to copy the source code and do this on my localhost to check them)
I was able to find out what tags and values to put, b/c get method. So here is the working code:
if ($category_id eq "xcomp") {
my $subjurl = "http://localhost/cgi-bin/mytestsearch2011.cgi?query=$search_key&verb_only=on&subject=on&exclude0=&exclude1=&exclude2=&exclude3=";
print qq(Subject\n)." ";
my $objurl = "http://localhost/cgi-bin/mytestsearch2011.cgi?query=$search_key&verb_only=on&object=on&exclude0=&exclude1=&exclude2=&exclude3=";
print qq(Object\n)." ";
my $prepurl = "http://localhost/cgi-bin/mytestsearch2011.cgi?query=$search_key&verb_only=on&prep=on&exclude0=&exclude1=&exclude2=&exclude3=";
print qq(Preposition\n)."<br><br>";
}
elsif ($category_id eq "subj") { ##List urls other than what is currently output:
my $enablingurl = "http://localhost/cgi-bin/mytestsearch2011.cgi?query=$search_key&verb_only=on&enabling=on&exclude0=&exclude1=&exclude2=&exclude3=";
print qq(Enabling Function\n)." ";
...
I don't understand all the exclude tags, but that's okay...
UPDATE: This works with POST as well, I just needed to know all the tags that came after the URL. Thanks!
