JAVA Software Developer/ Programmer

Ques:- Isn't it redundant to have to mark the methods final if the class is final?

Asked In :- LAP, presidio,

Jquery

Ques:- Is it possible to get value of multiple CSS properties in single statement?

Asked In :- Meditab Software, presidio,

Right Answer:
Yes, it is possible to get the values of multiple CSS properties in a single statement using the `getComputedStyle` method in JavaScript. For example:

```javascript
const element = document.querySelector('.your-element');
const styles = getComputedStyle(element);
const value1 = styles.property1;
const value2 = styles.property2;
```

In jQuery, you can use the `.css()` method to get multiple properties, but it returns them one at a time. You can also use an object to retrieve multiple values:

```javascript
const values = {
property1: $('.your-element').css('property1'),
property2: $('.your-element').css('property2')
};
```

Well, before jQuery 1.9 release it was not possible but one of the new feature of jQuery 1.9 was .css() multi-property getter.
Hide Copy Code
var propCollection = $("#dvBox").css([ "width", "height", "backgroundColor" ]);
In this case, the propCollection will be an array and it will look something like this.
Hide Copy Code
{
width: "100px",
height: "200px",
backgroundColor: "#FF00FF"
}

Vue.js

Ques:- What is v-model directive in Vue JS?

Asked In :- CodeCraft Technologies, Vanilla Networks, Aptroid, Young Globes, HuntingCube, CodeStore, Technoforte Software, Emvigo Technologies, Relinns Technologies, Ulearn,

Right Answer:
The `v-model` directive in Vue.js is used for creating two-way data bindings on form input elements, allowing the model data to be automatically updated when the input value changes and vice versa.

Comments

Admin Feb 8, 2020

The v-model directive binds the value of HTML elements to application data. This is also known as two-way binding in Vue JS.
Two-way binding means that any data related changes affecting the model are immediately propagated to the matching view(s), and any changes made in the view(s) (say, by the user) are immediately reflected in the underlying model.

Example:
<div id="app">

</div>

Javascript

Ques:- what is interface ?

Asked In :- Addweb solutions, Acquia Inc., e2e, Aptos, Synapse Labs, KUB, SightSpectrum Technology Solutions (P), knowit, heartland dental, omc,

Right Answer:
In JavaScript, an interface is a defined structure that specifies a contract for objects, outlining the methods and properties they must implement, but it does not provide the actual implementation. JavaScript does not have built-in support for interfaces like some other languages, but you can simulate them using conventions or TypeScript.
