In short, I want to fetch data from diferents pages from one API I've made.
The API is https://joao-back-ecommerce-prod.herokuapp.com/store/ and as you can see I've multiples endpoints.
With svelte i'm trying to go from page to page in one click with increment function.
exemple:
<script context="module">
export async function load({ fetch, page }) {
const id = page.params.id;
const res = await fetch(
`https://joao-back-ecommerce-prod.herokuapp.com/store/products/?page=${id}`
);
const products = await res.json();
console.log(products);
if (res.ok) {
return {
props: {
products: products.results
}
};
}
return {
status: res.status,
error: new Error('Could not fetch the results')
};
}
</script>
<script>
export let products;
export let id = 1;
const next = () => {
id++;
};
</script>
<ul>
{#each products as product}
<li>
{product.title} - {product.description}
<a href={product.id}>hlmlll</a>
</li>
{/each}
<button on:click={next}>Next</button>
</ul>
I want to go to next page when click on button next. I thought that with increment id + 1 it will be work, but, it doesn't.
In the browser when I change the page number it works.
Any help?
You are just changing a local variable, it does not affect the url.
What you would do is navigate to the next page by changing the url.
There are two ways to do this:
import { goto } from '$app/navigation';
const next = () => goto(`/product/${id+1}`); // change to get correct path for you
or, a better way is to actually just link to the next page instead:
Next
The second option is preferred because you are in fact navigating for which you should use a link (buttons are for actions), it will also work if the user has javascript disabled.
SvelteKit will not actually go to the server and load a new page, it will just fetch the data from the load function and update accordingly, the user will not notice they are on a different page, only the url changes.
I have a utilities plugin for Nuxt.js that I created with a method to parse hashtags and mentions and replace them with <nuxt-link>. I am then using v-html to inject the converted data back into the template. My issue is that the <nuxt-link> are not being parsed with v-html.
import Vue from 'vue';
Vue.mixin({
methods: {
replaceMentions(data) {
// Tags
const tagRegEx = /\[#tag:[a-zA-Z0-9_-]*\]/g;
let tagMatch;
while ((tagMatch = tagRegEx.exec(data)) !== null) {
const tag = Array.from(tagMatch[0].matchAll(/\[#tag:(.*?)\]/g));
data = data.replace(tag[0][0], '<nuxt-link to="/search?q=' + tag[0][1] + '">#' + tag[0][1] + '</a>');
};
// Users
const userRegEx = /\[#user:[a-zA-Z0-9_-]*\]/g;
let userMatch;
while ((userMatch = userRegEx.exec(data)) !== null) {
const user = Array.from(userMatch[0].matchAll(/\[#user:(.*?)\]/g));
data = data.replace(user[0][0], '<nuxt-link to="/users/' + user[0][1] + '">#' + user[0][1] + '</>');
};
return data;
}
}
});
Does anyone have any tips for how I could make these work as proper nuxt compatible links? I already tried using <a> and it works fine, I would just prefer to utilize proper nuxt compatible links.
I think the discussion here basically answers the question: https://github.com/nuxt-community/modules/issues/185
Summarized, there are two options:
Render the HTML with a full Vue build and then attach the rendered node.
(Preferred) Find the links in the HTML and make them call router push instead of their default action.
I have a method that calls the user data via axios
// method name getUser()
const user = await axios.get(`/user/${this.id}`)
this.id = user.data.data.id
this.name = user.data.data.name
this.email = user.data.data.email
I then use that in the mounted so if user visits /profile/id
it'll load the user data
mounted() {
this.getUser()
}
I tried to upload an image and I emit the event using global event bus once the image is successfully uploaded.
this.$event.$emit('IMAGE_UPLOAD')
Then catch that on the mounted too
mounted () {
// if I remove this it works, but I need to preload the data of the user
this.getUser()
this.$event.$on('IMAGE_UPLOAD', () => {
this.getUser()
})
}
my problem is it doesn't change the image meaning I still need to refresh the page if I call the this.getUser() too inside the mounted.
So I'm wondering how to work around this.
Thanks!
Since the url and name of the image does not change when the new image is uploaded the image in the browser is not updated. So what I have done in the past is a little trick to essentially change the url to the image by adding a unique query parameter. So use a data property for the location of your user image and in your method where you update the users data also update the img url and add something unique to the query parameter. I usually use new Date().getTime(). So you will end up with something like /img/user-xxxx.png?1559289852686
data(){
userImg: '/img/user-xxxx.png'
},
methods:{
getUser(){
//... get your user data
.then((data)=>{
this.userImg = data.user.img +'?'+ new Date().getTime();
})
}
I have a page with big list of data and some buttons for filtering.
for example 2 buttons to filter by status:
Complete status
Cancel status
I want when the user clicked on the complete the url to be changed to
http://demo.com/list?filter=complete
the page does not reloading, it just for get specific url foreach filter button.
How can I implement the code in Nuxt application?
You cannot use $route or $router to change url, it set a new html5 history state and reload the page. So, to change url without reloading, history.replaceState do the job. In your page or component:
methods: {
onClickComplete() {
if (!process.server) { // I'm not sure it's necessary
history.replaceState({}, null, window.location + '?filter=complete') // or use your own application logic: globalSiteUrl, $route... or queryString some vars...
}
}
}
At first you should change your route with "$route.push" or click on
these ways change the route without reloading
After than you can use "pages watchquery" to handle event of changing route
https://nuxtjs.org/api/pages-watchquery/
first create this helper function
export function getAbsoluteUrl(to) {
const path = $nuxt.$router.resolve(to).href
return window.location.origin + path
}
this is example for my tabs
watch: {
tab(value) {
if (!process.server) {
const url = getAbsoluteUrl({
params: { ...this.$route.params, activeTab: value }
})
history.replaceState({}, null, url) // or use your own application logic: globalSiteUrl, $route... or queryString some vars...
}
}
},
I can't figure out how to embed a codepen using the recommended HTML method i a Vue application.
As <script> tag cannot be part of a Vue component template, I tried to add it to index.html where my Vue application is injected without luck. However, when I tried to paste the html code outside the div where Vue resides, the code got turned into an iFrame as it should.
Here is the HTML embed:
<p data-height="265" data-theme-id="0" data-slug-hash="JyxKMg" data-default-tab="js,result" data-user="sindael" data-embed-version="2" data-pen-title="Fullscreen image gallery using Wallop, Greensock and Flexbox" class="codepen">See the Pen Fullscreen image gallery using Wallop, Greensock and Flexbox by Dan (#sindael) on CodePen.</p>
And the script:
<script async src="https://static.codepen.io/assets/embed/ei.js"></script>
Embedding an iFrame directly works fine, but I wonder. Is there a way how to get the html working?
Look into the https://static.codepen.io/assets/embed/ei.js, then you will see it executes two steps:
check document.getElementsByClassName if exists, create it if not.
one IIFE to execute the embed.
So one hacky way as below simple demo:
copy the source codes from https://static.codepen.io/assets/embed/ei.js
copy the codes of first step then wrap it as one function = _codepen_selector_contructor
copy the codes of second step and remove () from the end, then wrap it as one function = _codepen_embed_method
create one vue-directive (I prefer using the directive to support the features which directly process Dom elements, you can use other solutions), then execute _codepen_selector_contructor and _codepen_embed_method
Probably you want to replace document inside _codepen_embed_method with el instead, then execute _codepen_embed_method(el). so that it will not affects other elements.
Below demo uses the hook='inserted', you could use other hooks if inserted can't meet your requirements.
let vCodePen = {}
vCodePen.install = function install (Vue) {//copy from https://static.codepen.io/assets/embed/ei.js
let _codepen_selector_contructor = function () {
document.getElementsByClassName||(document.getElementsByClassName=function(e){var n,t,r,a=document,o=[];if(a.querySelectorAll)return a.querySelectorAll("."+e);if(a.evaluate)for(t=".//*[contains(concat(' ', #class, ' '), ' "+e+" ')]",n=a.evaluate(t,a,null,0,null);r=n.iterateNext();)o.push(r);else for(n=a.getElementsByTagName("*"),t=new RegExp("(^|\\s)"+e+"(\\s|$)"),r=0;r<n.length;r++)t.test(n[r].className)&&o.push(n[r]);return o})
}
let _codepen_embed_method = //copy from https://static.codepen.io/assets/embed/ei.js then removed `()` from the end
function(){function e(){function e(){for(var e=document.getElementsByClassName("codepen"),t=e.length-1;t>-1;t--){var u=a(e[t]);if(0!==Object.keys(u).length&&(u=o(u),u.user=n(u,e[t]),r(u))){var c=i(u),l=s(u,c);f(e[t],l)}}m()}function n(e,n){if("string"==typeof e.user)return e.user;for(var t=0,r=n.children.length;t<r;t++){var a=n.children[t],o=a.href||"",i=o.match(/codepen\.(io|dev)\/(\w+)\/pen\//i);if(i)return i[2]}return"anon"}function r(e){return e["slug-hash"]}function a(e){for(var n={},t=e.attributes,r=0,a=t.length;r<a;r++){var o=t[r].name;0===o.indexOf("data-")&&(n[o.replace("data-","")]=t[r].value)}return n}function o(e){return e.href&&(e["slug-hash"]=e.href),e.type&&(e["default-tab"]=e.type),e.safe&&("true"===e.safe?e.animations="run":e.animations="stop-after-5"),e}function i(e){var n=u(e),t=e.user?e.user:"anon",r="?"+l(e),a=e.preview&&"true"===e.preview?"embed/preview":"embed",o=[n,t,a,e["slug-hash"]+r].join("/");return o.replace(/\/\//g,"//")}function u(e){return e.host?c(e.host):"file:"===document.location.protocol?"https://codepen.io":"//codepen.io"}function c(e){return e.match(/^\/\//)||!e.match(/https?:/)?document.location.protocol+"//"+e:e}function l(e){var n="";for(var t in e)""!==n&&(n+="&"),n+=t+"="+encodeURIComponent(e[t]);return n}function s(e,n){var r;e["pen-title"]?r=e["pen-title"]:(r="CodePen Embed "+t,t++);var a={id:"cp_embed_"+e["slug-hash"].replace("/","_"),src:n,scrolling:"no",frameborder:"0",height:d(e),allowTransparency:"true",allowfullscreen:"true",allowpaymentrequest:"true",name:"CodePen Embed",title:r,"class":"cp_embed_iframe "+(e["class"]?e["class"]:""),style:"width: "+p+"; overflow: hidden;"},o="<iframe ";for(var i in a)o+=i+'="'+a[i]+'" ';return o+="></iframe>"}function d(e){return e.height?e.height:300}function f(e,n){if(e.parentNode){var t=document.createElement("div");t.className="cp_embed_wrapper",t.innerHTML=n,e.parentNode.replaceChild(t,e)}else e.innerHTML=n}function m(){"function"==typeof __CodePenIFrameAddedToPage&&__CodePenIFrameAddedToPage()}var p="100%";e()}function n(e){/in/.test(document.readyState)?setTimeout("window.__cp_domReady("+e+")",9):e()}var t=1;window.__cp_domReady=n,window.__CPEmbed=e,n(function(){new __CPEmbed})}
