attributes

问题 Is this valid code with newer Delphi versions? // handle HTTP request "example.com/products?ProductID=123" procedure TMyRESTfulService.HandleRequest([QueryParam] ProductID: string); In this example, the argument "ProductID" is attributed with [QueryParam] . If this is valid code in Delphi, there must also be a way to write RTTI based code to find the attributed argument type information. See my previous question Which language elements can be annotated using attributes language feature of

问题 I hope you guys can help me with this one. How can I have a radio button id="A" change it's attribute to 'checked' when radio button id="B" is selected? Radio buttons A and B are in different groups. Thanks! 回答1: <input type="radio" name="group1" id="A">Radio A <input type="radio" name="group2" id="B">Radio B <input type="radio" name="group2" id="C">Radio C $("input[type='radio'][name='group2']").change(function() { if ($('#B').is(':checked')) { $('#A').prop("checked", true); } else { $('#A')

问题 I'm getting these little diamonds with question marks in them in my HTML attributes when I present data from my database. I'm using EPiServer and a few custom properties. This is the information I've gathered, I save my data as a XML document, since I use custom EPiServer properties which need more than one defined value. This is saved as UTF8. It's only attributes in element tags which have this problem, such as align=left becomes align=�left�. There is no " character there, but I get the

问题 I want to evaluate my classification models with a ROC curve. I'm struggling with computing a multiclass ROC Curve for a cross-validated data set. There is no division in train and test set, because of the cross-validation. Underneath, you can see the code I already tried. scaler = StandardScaler(with_mean=False) enc = LabelEncoder() y = enc.fit_transform(labels) vec = DictVectorizer() feat_sel = SelectKBest(mutual_info_classif, k=200) n_classes = 3 # Pipeline for computing of ROC curves clf

问题 This question has been asked before, but the code they answer doesn't apply to me. I want to check when two rectangles collide in my game, and for the circle, I put a rectangle behind the circle(it's colored black). However, when I run, I get an error saying the rectangle needs to have a rect attribute. Here is my code: clock = pygame.time.Clock() pygame.init() change = False screen = pygame.display.set_mode((400, 300)) done = False x = 100 y = 30 bound = False while not done: for event in

问题 `Has anyone seen the following error in Datawedge 3.2.4: Error : Scanner : SCN1: Failed to get supported RSM attribute count. Error=a0000012 Error : Scanner : SCN1: Scanning failed. Error : a000001d . If so do you know the cause or fix?` 回答1: One possibility is that your scanner is trying to connect by wireless or Bluetooth to a nearby network. Finale Data Collector operates in disconnected mode, so you don't need any wireless communication on the scanner. You can turn off the scanner's

问题 I know it's possible to get all content attributes on a a standard HTMLElement like this: <input type="text" value="John" /> const input = document.querySelector("input"); const attrs = Array.from(input.attributes); console.log(attrs.map(a => a.name + ': ' a.value)); // [ "type: text", "value: John" ] I'm working in a world (Salesforce Lightning Web Components) where IDL attributes (i.e. those you can access via dot notation) aren't always exposed as content attributes at runtime. For example
