Any idea if I can use classes with dashes in Markaby?
Doing div.label-center in mab file results in this HTML:
<div class="label -"><center>
Bonus question - is Markaby dead or alive?
If you want to do this you must send a message to class because - is an operator in Ruby. Write code that way:
div.send(:'label-center')

In my Spring Controller I set following to my model attribute:
model.addAttribute("abc-def", "Hello World");
In my thymeleaf html I want to read the value of abc-def.
<th:block th:text="${abc-def}"></th:block>
But I get the error:
The operator 'SUBTRACT' is not supported between objects of type 'null' and 'null'
Its clear because - is an arithmetic operator. Is there a way to escape - for reading out the model value?
My advice would be: don't use variables names with dashes in them. (Would you try to define a variable int abc-def = 5; in java?)
In any case, this seems to work if you have to use it:
<th:block th:text="${#request.getAttribute('abc-def')}" />
Thymeleaf 2
Per the Expression Basic Objects section of the documentation (with more details in Appendix A), the context variables are in a #vars object. So, you can access variables with something like this:
<th:block th:text="${#vars.get('abc-def')}" />
Thymeleaf 3
As Metroids commented this all changes in Thymeleaf 3. It combines the #ctx and #vars objects, so you need to use the Context's getVariable method:
<th:block th:text="${#ctx.getVariable('abc-def')}" />
But this isn't the best plan
While certainly these will "work", having variables with punctuation in them is a bit unusual, and may confuse the next programmer to see your code. I wouldn't do it unless I had a really good reason to use that name.
I have a problem similar to some I've found on stackoverflow, but not quite the same. I'd like to avoid the solution to the following question:
https://stackoverflow.com/a/10407782/996587
Basically, would like the following HTML output:
<div class='myclass' extraattr='UNESCAPED <>& CONTENT'>
Content...
</div>
The HAML I'm using looks like this:
.myclass{ "extraattr" => "UNESCAPED <>& CONTENT" }
Content...
I can't quite figure out how to get the content to output the way I want. Tried applying .html_safe to the end of the string, but got the following error:
undefined method `html_safe' for "UNESCAPED <>& CONTENT":String
Later realized that for this particular application I'm not using Rails, just ruby + HAML. (I inherited this project and I'm just starting to learn HAML, ruby, and Rails anyways)
And again, for those of you too lazy to click links and didn't read the solution I referred to, I'd prefer not to configure HAML to not escape attrs for the entire file, just for this one attribute.
Thanks!
UPDATE
I just found the :plain filter, and was able to get what I wanted using that. However, if there's a trick I don't know about so I don't have to write all the HTML, I'd appreciate it. My "fix":
:plain
<div class='myclass' extraattr='UNESCAPED <>& CONTENT'>
Content...
</div>
There isn’t (currently) any way to turn off escaping for an individual attribute in Haml outside of Rails, it’s all or nothing using the :escape_attrs option. Depending on what you want, it might be worth looking at the :once option.
When Haml is used in Rails, it replaces the html escaping methods with some that respect the html_safe value that ActiveSupport adds (see lib/haml/helpers/xss_mods.rb).
It is possible to use these methods outside of Rails if you want. You will need to add html_safe and html_safe? methods to the String class in order for this to work (be careful here, this example is only a “poor man’s” version of the full XSS protection that Rails provides, it won’t really protect you from much but it will allow selective escaping of attributes).
Add the following somewhere after requiring Haml (it might be best in its own file that gets required):
class String
def html_safe?
defined?(#html_safe) && #html_safe
end
def html_safe
#html_safe = true
self
end
end
require 'haml/helpers/xss_mods'
module Haml::Helpers
include Haml::Helpers::XssMods
end
Now you can use html_safe on your strings, and Haml won’t escape them:
.myclass{ "extraattr" => "UNESCAPED <>& CONTENT".html_safe,
"otherextraattr" => "ESCAPED <>& CONTENT"}
Content...
Output:
<div class='myclass' extraattr='UNESCAPED <>& CONTENT' otherextraattr='ESCAPED <>& CONTENT'>
Content...
</div>
Have you tried using a \ to escape the characters.
{ :myattr => '\<\>\&' }
I'm wondering if xpath has a way to test an element for a class. I currently have the ID, I would just like to be able to test to ensure JS added a class.
My element where I'm testing to see if id=foo contains class=red.
<span id="foo" class="red">test</span>
I'm assuming you would use xpathCount?
getXpathCount(("//a[#id='foo']") not sure what goes next).equals(1);
I've also tried this without success,
getXpathCount("//span[#id='foo'].span[contains(#class,'red')]").equals(1);
The xpath to use would be
//a[#id='foo' and #class='red']
I have an element whose html is like :
<div class="gwt-Label textNoStyle textNoWrap titlePanelGrayDiagonal-Text">Announcements</div>
I want to check the presence of this element. So I am doing something like :
WebDriver driver = new FirefoxDriver(profile);
driver.findElement(By.cssSelector(".titlePanelGrayDiagonal-Text"));
But its not able to evaluate the CSSSelector.
Even I tried like :
By.cssSelector("gwt-Label.textNoStyle.textNoWrap.titlePanelGrayDiagonal-Text")
tried with this as well :
By.cssSelector("div.textNoWrap.titlePanelGrayDiagonal-Text")
Note : titlePanelGrayDiagonal-Text class is used by only this element in the whole page. So its unique.
Contains pseudo selector I can not use.
I want to identify only with css class.
Versions: Selenium 2.9 WebDriver
Firefox 5.0
When using Webdriver you want to use W3C standard css selectors not sizzle selectors like you may be used to using in jquery. In your example you would want to use:
driver.findElement(By.cssSelector("div[class='titlePanelGrayDiagonal-Text']"));
From reading over your post what you should do since that class is unique is just do a FindElement(By.ClassName("titlePanelGrayDiagonal-Text"));
Also the CssSelector doesn't handle the contains keyword it was something that the w3 talked about but never added.
I haven't used css selectors, but this is the xpath selector I would use:
"xpath=//div[#class='gwt-Label textNoStyle textNoWrap titlePanelGrayDiagonal-Text']"
The css selector should then probably be something like
"css=div[class='gwt-Label textNoStyle textNoWrap titlePanelGrayDiagonal-Text']"

Did you ever tried following code,
By.cssSelector("div#gwt-Label.textNoStyle.textNoWrap.titlePanelGrayDiagonal-Text");
I believe using a wildcard in CSS would be more helpful. Something as follows
driver.findElement(By.cssSelector("div[class$='titlePanelGrayDiagonal-Text']");
This will look into the class attribute and see what that attribute is ending with. Since your class attribute is ending with "titlePanelGrayDiagonal-Text" string, the added '$' in the css statement will find the element and then you can perform whatever action you're trying to perform.
I currently have some haml code which reads as
%span.flagb.flag-gb
this builds me a nice span which the classes:
flagB
flag-gb
(which puts a nice sprite on the page of the gb (great britian) flag
Now I dont want to hard code the gb I have the iso country code which I can access with a
=code
but I am so new I dont know about the best way of replacing the "gb" with the code value
Full code below as how i have it atm
- TZInfo::Country.all_codes.each do |code|
%li
%a(href='#')
%span.flagb.flag-gb
=code
only way I have managed it so far is using pure html
<span class='flagB flag-#{code'></span>
Thanks
The .classname syntax is just a shorthand, you can do it the long way:
%span{:class => "flagb flag-#{code}"}
See the HAML reference on class and id attributes for more information.
