I'm a newbie to Vue.js and facing a challenge with assigning a property to a link. I'm unsure of how to write the "counter" variable from "data" in order for it to properly function as intended.
export default {
name: 'app',
data () {
return {
counter: 1,
}
},
created(){
axios.get('http://jsonplaceholder.typicode.com/posts?
_start=${counter}+0&_limit=10').then(response => {
this.posts = response.data
})
}
}
Axios offers the convenience of adding URL query parameters as an object:
axios.get('http://jsonplaceholder.typicode.com/posts', {
params: {
_start: this.counter, //or `${this.counter}+0` if you require it as a string with +0 at the end
_limit: 10
}
})
.then(function (response) {
this.posts = response.data
})
.catch(function (error) {
console.log(error)
})
Using this method produces the same outcome but presents a cleaner and more maintainable approach when dealing with multiple parameters in URLs 😊
I always refer to this axios cheat sheet whenever I work with Axios.
To implement Template literals, you should utilize them because they "are string literals allowing embedded expressions," as pointed out by Matt. Instead of using single or double quotes, opt for backticks (`) for better functionality. For more information, check out: Template literals. Additionally, using this allows you to access the variable since counter is part of the data object which serves as a global object. A "global object is an object that always exists in the global scope," and with the use of the "this" keyword, you can reach a global object at the global level. Learn more from here and here. So, your code snippet should appear like this:
created(){
axios.get(`http://jsonplaceholder.typicode.com/posts?_start=${this.counter}+0&_limit=10`).then(response => {
this.posts = response.data
})
},
