var divfoo=document.getElementById("foo");
divfoo.className=" css-class css-class2 ";
divfoo.className=divfoo.className.replace(" css-class2 ", "");
The above code works. but I would like to make changes to last line of above code which is using replace method. Instead of writing the code like above, I would like to know why doesn't it work when written like below.
var divfoo=document.getElementById("foo");
divfoo.className=" css-class css-class2 ";
divfoo.className.replace(" css-class2 ", "");
Why should one assign to "divfoo.className" when applying replace method to the same "divfoo.className", why can't we just apply method directly like above code did?
Because of this should I hate javascript for not being logical?
enter code here
Element.className is a plain string representation of class HTML attribute.
String.replace method does not change the source string that is called on, just returns the result of replacement procedure.
If you want more "logical / functional" approach, look at Element.classList interface, namely the remove method.

I want to put found text in a list then .log() it
I copied the .replace() method from my previous code but I only know how to make it put a space after 5 letters. Is there a way to make it separate each "word" from a different div's? My log looks like this log and I want it to look like:
isSystemObject name description avatar tags isSystemObject name description avatar tags
Appreciate all the help
You can use the each() method to loop over all elements, extract the text and then apply the replace() method like this:
cy.get('#header').find('#label').each(($ele) => {
const nazwy = $ele.text().trim().replace(/(.{5})/g,"$1 ")
cy.log(nazwy)//prints label texts one by one
})
I am a little lost here.
Given the following method:
[ODataRoute("MktInstrument(Symbol={symbol})")]
public MktInstrument MktInstrument(string symbol) {
I call it using a URL in the form of:
http://localhost/MktInstrument(Symbol='FOREX!EURxUSD')
That is nice - but the variable symbol now includes the ' that wrap the parameter.
if I put that into the template
[ODataRoute("MktInstrument(Symbol='{symbol}')")]
I get an error that the template is not valid.
If I call it witout the warapping
http://localhost/MktInstrument(Symbol=FOREX!EURxUSD)
then the method is not called. Am I really supposed to remove the '' around the string parameter myself or am I missing something?
In your controller, you can make the action method like "public IHttpActionResult Function([FromODataUri]string symbol)" which means you add attribute [FromODataUri], it will not have single quotes. You can refer to http://odata.github.io/WebApi/#04-06-function-parameter-support, the related statement is
‘[FromODataUri]’ is mandatory for complex, entity and all collection. However, it is optional for Primitive & Enum. But for string primitive type, the value will contain single quotes without ‘[FromODataUri]’.
I need to know whether it is possible to use a datasource property in XPath Expression panel of XPath Match Configuration. For instance, if we have the following XML document:
<ns1:Ions>
<ns1:Ion>UI</ns1:Ion>
<ns1:IonType>X</ns1:IonType>
<ns1:StartDate>2010-05-10</ns1:StartDate>
</ns1:Ions>
<ns1:Ions>
<ns1:Ion>HH</ns1:Ion>
<ns1:IonType>RI</ns1:IonType>
<ns1:StartDate>1998-11-23</ns1:StartDate>
</ns1:Ions>
<ns1:Ions>
<ns1:Ion>CF</ns1:Ion>
<ns1:IonType>A</ns1:IonType>
<ns1:StartDate>2000-06-10</ns1:StartDate>
</ns1:Ions>
I need to evaluate to see whether a content of IonType is 'A' only if its sibling node, Ion, has a value of 'CF'. I was hoping to accomplish this by setting XPath Match Configuration as following:
XPath Expression (DataSourceInput#ION is 'CF')
declare namespace ns1='http://my.namespace.com';
//ns1:Ions[ns1:Ion[text()=${DataSourceInput#ION}]]/ns1:IonType/text()
Expected Results (DataSourceInput#ION_TYPE is 'A')
${DataSourceInput#ION_TYPE}
Running the test would result in SoapUI [Pro] to error the following, Missing content for xpath declare. If I replace ${DataSourceInput#ION} with an actual value, i.e. 'CF', the test works accordingly (I even tried place single quotes around ${DataSourceInput#ION}, but it didn't work).
Is there another way of accomplish this in SoapUI?
I try what you do and it works for me if I put single quotes around the property:
declare namespace ns1='http://my.namespace.com';
//ns1:Ions[ns1:Ion[text()='${DataSourceInput#ION}']]/ns1:IonType/text()
Did you check that testStep name is exactly DataSourceInput? If there are spaces in the TestStep name (i.e your testStep name is Data Source Input you have to put ${Data Source Input#ION}).
Anyway I give you another way to do so, you can add a testStep of type groovy script after the testStep where you are getting the <Ions>response, and check the assert here like follows:
// get xml holder
def groovyUtils = new com.eviware.soapui.support.GroovyUtils(context);
def ionsHolder = groovyUtils.getXmlHolder("IonsTestStepName#response");
// generate xpath expression
def xpathExpression = "//*:Ions[*:Ion[text()='" + context.expand('${DataSourceInput#ION}') + "']]/*:IonType/text()";
log.info xpathExpression;
// get the node value
def nodeValue = ionsHolder.getNodeValue(xpathExpression);
// check expected value
assert nodeValue == context.expand('${DataSourceInput#ION_TYPE}'),'ERROR IONS VALUE';
Hope this helps,
If i have the & symbol in some field (from a db, cannot be changed), and i want to display this via freemarker... but have the display (from freemarker) read &, what is the way to do so?
To reiterate, I cannot change the value before hand (or at least, I don't want to), i'd like freemarker to "unmark" &.
To double re-iterate, this is a value that is being placed with a lot of other xml. The value itself is displayed on its own, surrouded by tags... so something like
<someTag>${wheeeMyValueWithAnAmpersand}<someTag>
As a result, i don't want all ampersands escaped, or the xml will look funny... just that one in the interpolation.
Oh goodness.
I see the problem: the code was written like this:
<#escape x as x?xml>
<#import "small.ftl" as my>
<#my.macro1/>
</#escape>
and at which i'd assumed that the excape would excape all the calls within it - it is certainly what the documentation sort of implies
http://freemarker.org/docs/ref_directive_escape.html
<#assign x = "<test>"> m1>
m1: ${x}
</#macro>
<#escape x as x?html>
<#macro m2>m2: ${x}</#macro>
${x}
<#m1/>
</#escape>
${x}
<#m2/>
the output will be:
<test>
m1: <test>
<test>
m2: <test>
However it appears that when you import the file, then this isn't the case, and the escape... escapes!
SOLUTION:
http://watchitlater.com/blog/2011/10/default-html-escape-using-freemarker/
the above link details how to solve the problem. In effect, it comes down to loading a different FreemakerLoader, one that wraps all templates with an escape tag.
class SomeCoolClass implements TemplateLoader {
//other functions here
#Override
public Reader getReader(Object templateSource, String encoding) throws IOException {
Reader reader = delegate.getReader(templateSource, encoding);
try {
String templateText = IOUtils.toString(reader);
return new StringReader(ESCAPE_PREFIX + templateText + ESCAPE_SUFFIX);
} finally {
IOUtils.closeQuietly(reader);
}
}
which is a snippet from the link above. You create the class with the existing templateLoader, and just defer all the required methods to that.
Starting from FreeMarker 2.3.24 no TemplateLoader "hack" is needed anymore. There's a setting called output_format, which specifies if and what escaping is needed. This can be configured both globally, and/or per-template-name-pattern utilizing the template_configurations setting. The recommend way of doing this is even simpler (from the manual):
[...] if the
recognize_standard_file_extensions setting is true (which is the
default with the incompatible_improvements setting set to 2.3.24 or
higher), templates whose source name ends with ".ftlh" gets "HTML"
output format, and those with ".ftlx" get "XML" output format
I am having a little bit of difficulty passing a variable into a selector in prototype. I would like to be able to pass a variable into the select string, so that one function can work for many of the same kind.
At the moment, this is what I would basically like to do:
function myFunct(var)
{
$(var + 'add_form').hide() //so inde the brackets would be ('#product1 #add_form') for example.
}
Be able to pass 'var' into the function that would pass it to the selector, so that I can hide a pattern that is the same for many on the page.
Any ideas for a path to follow would be greatly appreciated.
You're on the right track! Couple things:
var is a JavaScript keyword (source), don't use it to name a variable
if you're querying an element by id (such as #add_form) you don't need to add any container element as you're doing
If you're querying an element by class, you need to use the $$ function, not the $ function
You need to iterate over the wrapped set to call your method
whitespace is significant in css selectors, so make sure to include those in your selector construction to tell Prototype to search within your parent container:
function myFunct(parent) {
$$(parent + ' .add_form').invoke('hide')
}
myFunct('#someparent'); // hides .add_form inside #someparent
That should work... just rename var to something else.
function myFunct(yourVar)
{
$$('#' + yourVar + ' .add_form').each(function(s){ s.hide(); }); // yourVar being the id of the container element
}
I've put a '.' in front of add_form because you can't use multiple elements with same ID, make it a class.
