I am coming from Adobe Coldfusion and I'm trying to debug a component in Lucee by writing values to the output. Normally what I do is:
component Sample {
remote Void function spotCheck() {
writeDump(1234);
writeOutput("<br>Test");
return
}
Then hit the page to HTTP://localhost/sample/Sample.cfc?method=spotCheck
But it does not work. I updated the function to have a returnformat="text", but then the output is plain text with HTML tags in its text form. I tried setting it to "html" instead of text but then I get the error below:
This page contains the following errors:
error on line 20 at column 17: xmlParseEntityRef: no name
Below is a rendering of the page up to the first error.
I'm probably doing it the wrong way and I'm happy to learn the Lucee way of how to easily inspect values of variables inside a component function.
PS: I don't have/use step by step debugger.

I'm trying to access the local storage data in Edge set by my options page, using my popup script. Is there a current, working example of this available?
I was using localStorage, but it would only update the popup if I reloaded the extension after saving changes in my options page. I want to make it easier on the user by allowing the popup to access it immediately after saving, without reloading. I found the browser.storage.local.get(), but documentation conflicts everywhere I look, and I can't find viable working examples.
I have used, per Edge documentation:
browser.storage.local.get("sample");
But it throws an error requiring a callback function. So then I used:
let sample = browser.storage.local.get("example");
sample.then(ifGood, ifBad);
I get an error regarding property "then".
Then I simply tried adding a callback to the action itself:
sample = browser.storage.local.get("example", callbackFunction);
function callbackFunction(data){
alert(data);
}
The end alert should display a string, but it just displays an empty Object. How do I access the data returned in the callback? I tried callbackFunction(this) as an argument in the get, but it throws an error about the syntax of the get.
I found a work-around using browser.runtime.reload() in the Options page when saving the changes. It still reloads the extension, but it does it without requiring the user to do it manually.
You should use this syntax:
browser.storage.local.get(propertyName | null, callbackFn)
where
callbackFn = function fn(resultObject) {...}
When you pass null you will get whole storage object.
Look for example 1 or example 2 in my Edge extension.
I'm building up a test in Geb (WebDriver) and need to submit a form which will create a file in response.
I am able to download the file (the Browser save it automatically to the disk), but I wand to check it in GEB.
I've tried withNewWindow(), but it only works on URIs??
I've tried downloadXXX(), but no luck either...
How can I download a file into a variable?
class CSVTest extends GebReportingTest
#Test
void csvCreation() {
to CSVExport
// select entries / fill values
selectAllEntries.value(true)
//// this will do a post
//// the server will render a file and deliver it back as a result of the submit
// CORRECTLY downloads the file
submitButton.click()
// NOT WORKING
withNewWindow (submitButton.click()) {
...
}
// NOT WORKING
def csv = download(submitButton.click())
}
}
You won't be able to intercept the file downloaded by the browser after clicking a button that does a post in any way unfortunately.
You will have to synthesize a post request with the right content which is sent when using the form. While it is possible to do so using Geb's DownloadSupport class it will be complicated and clunky. You're better off using a library for which performing such requests is the main functionality, like for example REST-Assured.
In the below example, infoScroller is a UIWebView and println(HTMLDescription) prints a lovely string of HTML. However, the attempt to loadHTMLString gets the runtime error: fatal error: Can't unwrap Optional.None
if let HTMLDescription = self.myData?.content? {
println(HTMLDescription)
infoScroller.loadHTMLString(HTMLDescription, baseURL: nil)
}
I've tried every combination of ! and ? in both the assignment and use of the string but I get this same error every time, though the variable never fails to print out perfectly to the console.
There is another value that I set using the same method and it works fine. Both are strings, but the other one is more simple in that HTMLDescription is multiline and the working one is not.
Edit: The discussion in the comments prompted me to check the infoScroller and it's description as printed in the console is: (#sil_weak UIWebView!) infoScroller =
I'm thinking that's the issue, but I'm not sure what it means or how to fix it.
Edit 2: This has to be the issue. println(infoScroller.description) yields the exact same error.
Got it! This question put me on the path. I was trying to load the content before the view was fully loaded. Moved loadHTMLString() into viewDidLoad(). Stupid simple.
I'm having a few issues with Jade and scope of variables exported from the route. This might be an obvious answer, but my googling abilities have failed me.
In my route, I have this code :
res.render('index', {title: "App",
csvData: json // This is a json object
};
In my view, I want to display the length of the json object on the click of a button. My jade looks like this :
extends layout
block content
script
-var test123 = csvData;
-console.log(test123.length);
div
button.btnCSV(onclick='console.log(test123)') Save As CSV
The first console.log prints the correct length, but when I do press the button, it tells me that test123 is undefined. I think this has something to do with the difference between client side/server side variables. If that is the case, is there anyway to make a server side variable accessible to a client side scope?
I'm not sure how your example would work with the script content prefixed with a -, this indicates unbuffered code. JavaScript that runs server side and that produces no direct output, so your in-line script is most likely empty.
Similarly your onclick handler is just compiling a string on the server, which is the main problem you appear to report.
In order to achieve what you trying to do, you should define a function in the script block which can be called from your buttons onclick handler. Take care to ensure that your script keyword ends with a . so that the following lines are treated as block content of the script.
Here's what your template should look like.
extends layout
block content
script.
var test123 = !{JSON.stringify(csvData)};
function printLength() {
console.log(test123.length);
}
div
button.btnCSV(onclick='printLength()') Save As CSV
Then on the server side make sure you're returning an actual JavaScript object, or an Array, and not a string representation... it should look like this
res.render('index', {title: "App",
csvData: [{ val1: 'value1', val2: 'value2' }]
};
This allows variables to be used for server side scripting (if required) as well as client side.
My javascript code looks like this
var query = window.location.search.replace('?','');
fetchContent(apiUrl + 'service/' + query + '?callback=?', function(data) {
$('.content').append(data).trigger('create');
});
I am using jQueryMobile, nodeJS for services and views. Also, using EJS templates to display data.
The problem is that I am not able to get value for variable query in the above code and hence the next following lines form up a parameter 'apiUrl/service/?callback=?' for fetchContent method which is a wrong URL for my service. The correct parameter for my fetchContent method should be 'apiUrl/service/1234?callback=?'.
Interesting thing is that this code works fine when I open the link in new tab. URL for the above HTML page in my code is some.html?1234. According to this the value in JS code should be 1234 but it is empty.
