I want to go to my search page in nuxt myApp.com/search?parameter=1 from my main page. In the main page I can go to search page in two ways, by using a nuxt-link:
<NuxtLink
:to="`/search?parameter=${number}`"
>
</NuxtLink>
Or I can go with a method:
goToSearch() {
this.$router.push(`/search?parameter=${this.number}`);
},
When I use the nuxt-link and land on search page the url is correct with parameter: myApp.com/search?parameter=1
But when I use my method which is conencted to a button in the page and I land on search page the url becomes myApp.com/search which is problematic for me!
Please note I have two have both the method and the nuxt-link. How can I fix it so when I use the method and go to search page I keep the parameters?
You should use this, as mentioned in the documentation
<nuxt-link :to="{ path: 'search-page', query: { search: number } }">
Try search page
</nuxt-link>
You can also use it this way, depending on what you're trying to achieve.
<button #click="$router.push({ path: 'search-page', query: { search: number } })">
Try some other way
</button>
A correct /pages/search-page.vue page can be found here.
I'm currently developing a universal app using Nuxt.js, the data on most of the pages is retrieved from an API using a fetch hook as well as vuex store. I started noticing errors on page reload/refresh and sometimes when I visit a page from the navbar. The page error is:
TypeError: Cannot read property 'data' of undefined
where data is an object retrieved from an API. I have searched around the internet for this and found it has something to do with data not being loaded or page rendering whilst the data is not fully retrieved. i have found a work around by using a v-if on my template to check if the data is set then display the contents. my question is if there is a way to achieve this, i have tried using the async/await keywords but it doesn't help and i feel like the v-if method is not the best way to handle it.
edit: solved by using $fetchState.pending when using fetch()
If in your template you display right away the data you retrieve from the API, then indeed using the v-if is the right way to do.
If you are using the new fetch() hook, then in your template you can use $fetchState.pending to check if the loading has finished, for example:
<div v-if="$fetchState.pending">
<p> Content is loading... </p>
</div>
<div v-else>
<p> Content has loaded! {{data}}</p>
</div>
<script>
export default{
data(){
return{
data: null
}
}
async fetch(){
this.data = await getSomeAPI
}
}
</script>
I'm working on a project where I keep a log of key actions by users. For example a log entry is made when a user logs in to the application. I use a Laravel API as backend that takes care of the logging the event in the database and takes care of retrieving log entries to be displayed in the application. An example of a log entry returned for display is the following:
{{user|123|"John Doe"}} logged in at 2020-01-03 11:00:05
Now, I'd like Vue to automatically recognize that this should be replaced by the following:
<router-link to="/user/123">John Doe</router-link> logged in at 2020-01-03 11:00:05
So it automatically becomes a clickable link that navigates to the user profile in this case.
Does Vue offer any such functionality? Any ideas on how to approach this?
Thanks!
Yes, you can bind to to a computed property that will build the path string or data property (then you need to save the builded path in a data section when receving your response):
Template:
<router-link :to="path">{{userName}}</router-link>
script:
export default {
data() {
return {
path: '',
userName: ''
}
},
// OR
computed: {
path() {
<build your path from entry variable>
return <your builded path>
},
userName() {
<extract your user name>
return <extracted user name>
}
}
}
<div v-for="user in users" :key="user.id">
<router-link :to="user.path">{{user.name}}</router-link>
logged in at {{ user.loginTime }}
</div>
I think I will use a v-for to do this, I am wondering what data you got from your Ajax api ?
Is it possible for a route-href generated link to have the replace=true option when pushState is enabled?
I have tried:
<a route-href="route: user/details; options.bind: {replace: true}">Link</a>
and it does not work. There is no error and the view changes but after clicking the link a new item in the browser history appears (and it should not).
I don't believe so. The route-href generates an href attribute containing the url to the specified route. To navigate to a route using replace: true you'd have to create a method in your view-model and call this method using a click event. Something like this:
ViewModel
goToRoute() {
this.route.navigateToRoute('myRoute', { id:'someId' }, { replace: true });
}
View
<a click.delegate="goToRoute()"></a>
I'm having a bunch of problems getting jQuery's .on to work with my Rails ajax link.
Specifically, I've got this link:
<div id="item_7_tools" class="item_tools">
<a rel="nofollow" id="book_item_7" data-remote="true" data-method="post" class="book_link" href="bookings">Book this item</a>
</div>
I've trimmed some of the text in the HTML, but suffice to say that that, and my controller response work.
I click "Book this item", it goes off to the controller, the controller does its magic, and sends back my partial that replaces the contents of that div.
So I'm now trying to replace the contents with an ajax spinner while the loading is working, and that's where its going pear-shape.
I'm trying this initial bunch of jQuery code just to make sure I've got my javascript working:
$('div.item_tools')
.on('click', 'a', function() {
console.log("clicky click")
})
.on('ajax:beforeSend', "a", function() {
console.log('the a in div.item_tools is sending its ajax command');
})
.on('ajax:complete', "a", function() {
console.log('ajax request completed');
})
My understanding of that, is that when I then click any link (a) that lives within an element with the item_tools class, it will bubble up to this function, and then log the message into the console. Similarly, a link that has triggered an ajax request will get the same treatment...
(And assuming I can get that to work, then I'll go to work doing the ajax loader spinner).
The behaviour I'm seeing instead, is that when I click the link, there are no messages appearing in my console (trying this on both firefox and chrome), and my ajax link goes off and does its stuff correctly. Just completely ignoring the javascript...
Is this because my clicking the ajax link somehow has blocked the click event from bubbling up? I know that there's a way to do that, but I don't think I've done it anywhere knowingly. Unless OOTB rails/ujs does that?
So my questions:
Is there a way to tell what has had a binding attached to it?
What am I doing wrong with my javascript?
Thanks!
I use this all the time... and it seems to work fine.
Have you tried adding one that's .on('ajax:success')?
Besides that try putting the . for each line on the previous line...? It's possible that it gets to $('div.item_tools') and then auto-inserts a semi-colon as per javascript's standard... Although if that were the case I'd expect it to give you a JS error about the . on the next line. In any case try changing it to:
$('div.item_tools').
on('click', 'a', function() {
console.log("clicky click")
}).
on('ajax:beforeSend', "a", function() {
console.log('the a in div.item_tools is sending its ajax command');
}).
on('ajax:complete', "a", function() {
console.log('ajax request completed');
})
If worse comes to worse try just doing:
$("a").on("ajax:success", function(){
console.log('ajax:success done');
})
And see if it works without the event delegation...
Then change it to this:
$(document).on("ajax:success", "a", function(){
console.log("ajax:success with delegation to document");
})
And see if delegation works all the way up to document instead of just your item_tools
Are you sure that you've named everything right? it's div.item_tools a in your markup?
Turns out that the javascript was being triggered before the DOM had loaded, which meant that stuff weren't being bound...
$(function () {
$('div.item_tools')
.on('click', 'a', function itemToolsAjaxy() {
console.log("clicky click");
})
.on('ajax:beforeSend', "a", function() {
console.log('the a in div.item_tools is sending its ajax command');
$(this).closest('div').html('<img src=/assets/ajax-loader.gif>');
})
});
Added the $(function()) right at the beginning and it delayed the binding until after the DOM had loaded, and then it started working.
Figured this out by using the Chrome developer tools to stick a break on the div.item_tools selector and watched as the browser hit that even before the DOM had been loaded. /facepalm
(I removed the .on('ajax:complete') callback, because it turns out that there's a known limitation where the original trigger element no longer exists because it had been replaced, so there's nothing to perform the callback on. Not relevant to my original problem, but I thought I'd mention it.)
As far as i'm aware, you can either do ajax stuff 2 ways:
By using :remote => true
By using jQuery's $.ajax (or $.post).
With number 2, make sure to change your href='#'
My suggeston is to remove the :remote => true and manually make a jQuery ajax call. That way you can use beforeSend, complete, etc.
If i'm way off track here, someone please help clarify things for me as well.
