typing

问题 I'd like to type something in a IFrame with Selenium IDE but I don't know how to do this. Thanks a lot! 回答1: You have to select the iframe and then type selenium.selectFrame("css=iframe.widget[<a_css_identifier>]"); selenium.type(<your_object_or_text_box>, <typed_content>); The statements are in java, but you should be able to find selectFrame and type in the IDE. 回答2: You can use the Selenium IDE command 'selectFrame' to focus within an iframe. Use the Target field to enter the iframe id.

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 8 years ago . It has recently been brought to my attention that my typing skills leave much to be desired. I've been programming a few years in college now, and typing speed has never been very important. Classes do not focus on how much code you can output, but instead how to design and implement code. Now that I have a job

问题 I closely paralleled the approach taken in how-to-use-moment-js-library-in-angular-2-typescript-app but still get error TS2307: Cannot find module 'mqtt'. npm install --save mqtt <s>typings install --save mqtt</s that didn't find the typings but this did... typings install mqtt --save --ambient my tsconfig.conf looks like this { "compilerOptions": { "noImplicitAny": true, "module": "commonjs", "target": "ES5", "emitDecoratorMetadata": true, "experimentalDecorators": true, "sourceMap": true,

问题 This question already has answers here : Type hint for a function that returns only a specific set of values (3 answers) Closed 3 months ago . I'm using the new Python 3.5 module typing and it has been joyous. I was wondering how one might specify a type based on an exact string literal. For example, a function is guaranteed to return one of the four strings - "North", "West", "East", "South - how can we express that as a specific type variable, instead of just str . I looked through the

问题 Ada, Pascal and many other languages support ranges, a way to subtype integers. A range is a signed integer value which ranges from a value (first) to another (last). It's easy to implement a class that does the same in OOP but I think that supporting the feature natively could let the compiler to do additional static checks. I know that it's impossible to verify statically that a variabile defined in a range is not going to "overflow" runtime, i.e. due to bad input, but I think that

问题 Is it possible to define an interface which has some information on the format of a string? Take the following example: interface timeMarkers{ markerTime: string[] }; an example would be: { markerTime: ["0:00","1:30", "1:48"] } My question: Is there a way to define the type for markerTime such that that the string value must always match this regex, instead of declaring it as simply string[] and going from there? var reg = /[0-9]?[0-9]:[0-9][0-9]/; 回答1: There is no way to define such a type.

问题 I am currently learning Perl 5 from learn.perl.org and I am curious about its typing system. I see mixed information about Perl being weakly or strongly typed, and that it is also dynamically typed. Wikipedia states that it also supports duck typing. Can anyone confirm its weakly or strongly typed nature? 回答1: I see mixed information about Perl being weakly or strongly typed That's no surprise given that there is also conflicting information as to whether C is a strongly-typed or weakly-typed

问题 I'm trying to use the --strict option on tsc but I ran into the following "weird" case that I don't seem to understand. If I write: function testStrict(input: {query?: {[prop: string]: string}}) { if (input.query) { Object.keys(input.query).forEach(key => { input.query[key]; }) } return input; } the compiler complains about: test.ts(5,9): error TS2532: Object is possibly 'undefined'. (the offending line is input.query[key]; ) What I don't understand is, I have already checked for undefined

问题 Let's suppose there's a typing file for library X which includes some interfaces. interface I1 { x: any; } interface I2 { y: { a: I1, b: I1, c: I1 } z: any } In order to work with this library I need pass around an object that is of exactly the same type as I2.y . I can of course create identical interface in my source files: interface MyInterface { a: I1, b: I1, c: I1 } let myVar: MyInterface; but then I get the burden of keeping it up to date with the one from library, moreover it can be
