Vuejs 3 - Problem with data function inside a component

I have a list of projects which I get from an api. They get forwarded one by one to this component:
<template>
<button id="project-button" #contextmenu="handler($event)" class="btn btn-outline-secondary mt-1 ms-1" data-bs-toggle="collapse" :data-bs-target="`#${project.Name + project.ID}`">{{project.Name}}</button>
<div :id="`${project.Name + project.ID}`" class="collapse">
<button #click="setProjectId" id="add-object-button" class="btn btn-outline-secondary mt-1 ms-1" data-bs-toggle="modal" data-bs-target="#createObject">
<b>Add Data Object</b>
<i id="plus-icon" class="fas fa-plus"></i>
</button>
<DataObjects :dataObjects="dataobjects"/>
</div>
<CreateObjectModal #add-object="addObject" :projectId="projectId"/>
</template>
<script>
import DataObjects from './DataObjects'
import CreateObjectModal from './CreateObjectModal'
export default {
name: 'Project',
data() {
return {
dataobjects: [],
projectId: 0,
}
},
props: {
project: Object,
},
components: {
DataObjects,
CreateObjectModal
},
methods: {
setProjectId() {
console.log(this.project.ID)
this.projectId = this.project.ID
console.log(this.projectId)
},
async addObject(objectName) {
console.log(objectName)
console.log("After adding object: " + this.projectId)
console.log("Event arrived")
},
Inside the data function I have an object which has the attribute projectId. When I click on the Add Data Object button a modal opens where the user can type in the name of the data object. The modal opens through the data-bs-toggle and data-bs-target attributes. Now in my click event for this button I can get the individual id of a project depending on which button I click. But the problem here is that I will need the specific id of a project inside my addObject function. The addObject function gets called when I click 'Ok' in my modal after the user types in a name. The logs show clearly that if I click on a button the different id gets set correctly but when I click 'Ok' from the modal and the AddObject function gets called then the id remains 1 which is the first id of the projects
I dont know if I am complicating things but I tried to send the id to my modal component which didnt work. The idea was to send it back to the addObject function via $emit. I am kinda stuck with this problem and hope someone can help me. Here is the Modal Component:
<template>
<div>
<div class="modal fade" id="createObject" data-bs-backdrop="static" data-bs-keyboard="false" tabindex="-1" aria-labelledby="staticBackdropLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title">New Data Object</h5>
<button type="button" class="btn-close" data-bs-dismiss="modal" aria-label="Close"></button>
</div>
<div class="modal-body">
<div class="form-floating mb-3">
<input v-model="objectName" class="form-control" id="input">
<label for="input">Object Name:</label>
</div>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-secondary" data-bs-dismiss="modal">Close</button>
<Button data-bs-dismiss="modal" #click="createObject" :text="'Save'"/>
<p>{{projectId}}</p>
</div>
</div>
</div>
</div>
</div>
</template>
<script>
import Button from './Button'
export default {
name: 'CreateObjectModal',
data() {
return {
objectName: '',
}
},
props:{
projectId: Number
},
methods: {
createObject() {
this.$emit('add-object', this.objectName)
}
},
components: {
Button
},
emits: ['add-object']
}
</script>

How to use a loop inside a slick slider in Vue.js

I'm using vue-slick link https://www.npmjs.com/package/vue-slick inside a bootstrap modal and when i use a v-for loop to loop through the items it display's this.
Here's a snippet of my code
import Slick from 'vue-slick';

What could be the problem ?

Sorry guys I was too busy that I hadn't got time to post the above solution anyway I've figured a way to do it although the css styling needs polishing but it still solves what I wanted. What I did was to create property in data called currentIndex and also a function called current vehicle in the computed property. Then I looped the [currentIndex] to get the currentVehicle
computed:{
currentVehicle: function(){
return this.vehicles[Math.abs(this.currentIndex) % this.vehicles.length];
},
},
So the currentVehicle() returns the index of the vehicle in view.
Here's a working one

How to use Vue.js to template a Modal and reuse it?

So currently I have a web app that loads a dashboard based on a SQL database and that works just fine, each of these elements have buttons and those buttons are SUPPOSED to spawn a modal with the content of the problem and you can interact with it etc.
Recently I have figured out how to use Vue.js to run a function that grabs this information and populate it on the modal. However, this modal can only be templated ONCE before it wont work again. Ex: I can click on problem 1 and problem 1's information is correct. however, if I click problem 2 after that it doesn't work
new Vue({
delimiters: ['!!!','!!!'],
el: '#problem-modal',
methods: {
close() {
this.$emit('close');
},
},
data: {
items: [],
name: null,
summary: null,
},
mounted: function () {
var self = this;
fetch('./api/problems')
.then(response => {
var response = response.json();
return response;
})
.then(json => {
var data = json.data;
var length = data.length;
for (var i = 0; i<length; i++) {
if (data[i].unique_id == button_id) {
this.name = data[i].problem_name;
this.summary = data[i].summary;
}
}
})
}
})
}
Here is my Script for the vue, assume that the problems load perfectly and this:
<div class="modal fade" id="problem-modal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="exampleModalLabel">!!! name !!!</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
!!! summary !!!
</div>
<div class="modal-footer">
<button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Save changes</button>
</div>
</div>
</div>
</div>
is the modal. Any idea on how to make the modal element able to be used more than once?
Thanks!

I give you nearest illustration of your question ! I thought items is your problem list . As you mentioned you have to clicked button so that pass your clicked data to call method and grab data from items with that pass clicked data and set vue data . I hope it will be ok .. Look at my example
new Vue({
el: '#problem-modal',
methods: {
show(id) {
let cur = this.items.find(x => x.id == id);
this.name = cur.name;
this.summary = cur.summary;
}
},
data: {
items: [
{
id: 1,
name: "one",
summary: "one summary "
},
{
id: 2,
name: "two",
summary : "two summary"
}
],
name: null,
summary: null,
}
});
button {
width: 100%;
height: 20px;
margin: 10px 5px;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<div id="problem-modal">
<button v-for="item in items" #click="show(item.id)">{{item.id}}</button>
<div class="modal">
<h1>{{name}}</h1>
<pre>{{summary}}</pre>
</div>
</div>

Vue.js Display call one component from another component

I have 2 components:
Vue.component('repo-button', {
props:["check_in_id", "repo_id"],
template: '#repo-button',
methods: {
fetchRepo: function() {
url = window.location.href.split("#")[0] + "/check_ins/" + this.check_in_id + "/repositionings/" + this.repo_id + ".json"
cl(url)
cl(this)
var that;
that = this;
$.ajax({
url: url,
success: function(data) {
cl(data)
that.showRepo();
}
})
},
showRepo: function() {
// what do I put here to display the modal
}
},
data: function() {
var that = this;
return {
}
}
});
Vue.component('repo-modal', {
template: "#repo-modal",
data: function() {
return {
status: 'none'
}
}
});
var repositionings = new Vue({
el: "#repo-vue"
});
...and my view consists of a button and a modal. I'd like the button to call fetchRepo on the repo-button component and display the modal (change its status property from none to block.
<script type="text/x-template" id="repo-button">
<div class='socialCircle-item success'>
<i class='fa fa-comment'
#click="fetchRepo"
:data-check_in='check_in_id'
:data-repo='repo_id'>
</i>
</div>
</script>
<script type="text/x-template" id="repo-modal">
<div v-bind:style="{ display: status }" class="modal" id="vue-modal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true" data-client_id="<%= #client.id %>">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<h4 class="modal-title"></h4>
</div>
<div class="modal-body"></div>
<div class="modal-footer">
<button type="button" class="btn btn-danger btn-simple" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
</script>
<div id="repo-vue">
<div is="repo-modal"></div>
<div is="repo-button" repo_id="<%= ci.repositioning.id %>" check_in_id="<%= ci.id %>"></div>
</div>

Props down, events up
In Vue.js, the parent-child component relationship can be summarized
as props down, events up. The parent passes data down to the child via
props, and the child sends messages to the parent via events.
In particular, if the state of a component needs to be controlled externally (by a parent or sibling), that state should be passed in as a prop from the parent. Events indicate to the parent that the state should be changed.
Your modal's state is controlled by events in itself and in a sibling component. So the state lives in the parent, and is passed to the modal as a prop. Clicking the modal Close button emits a (custom) hidemodal event; clicking the sibling component's comment icon emits a showmodal event. The parent handles those events by setting its showRepoModal data item accordingly.
Vue.component('repo-button', {
template: '#repo-button',
methods: {
showRepo: function() {
this.$emit('showmodal');
}
}
});
Vue.component('repo-modal', {
template: "#repo-modal",
props: ["show"],
computed: {
status() {
return this.show ? 'block' : 'none'
}
},
methods: {
hideRepo() {
this.$emit('hidemodal');
}
}
});
var repositionings = new Vue({
el: "#repo-vue",
data: {
showRepoModal: false
}
});
.socialCircle-item i {
cursor: pointer;
}

Function to append modal

I have 3 modals that all have the same format and are activated by different onclicks (Create Contact, Update Contact, Delete Contact). I am wanting the modal-title and modal-body to change depending on which button was clicked. How would I go about creating a function that appends the modal content depending on which button was clicked? Thank you for your help!
<div id="myModal" class="modal fade">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h4 class="modal-title">Confirmation</h4>
</div>
<div class="modal-body">
<p>Contact Created!</p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">OK</button>
</div>
</div>
</div>

I have written the JavaScript "BootstrapModel" class for the same purpose.
It also depends on jQuery so don't forget to embed jQuery before using this class.
class is :
var BootstrapModal = (function (options) {
var defaults = {
modalId: "#confirmModal",
btnClose: "#btnClose",
title: "Confirm",
content: "Some bootstrap content",
onClose: function () {
},
onSave: function () {
}
};
defaults = options || defaults;
var $modalObj = $(defaults.modalId);
var hideModal = function () {
$modalObj.modal("hide");
};
var showModal = function () {
$modalObj.modal("show");
};
var updateModalTitle = function (title) {
defaults.title = title;
//$($modalObj).find(".modal-title").eq(0).html(title);
$modalObj.find(".modal-title").eq(0).html(title);
};
var updateModalBody = function (content) {
defaults.content = content;
$modalObj.find(".modal-body").eq(0).html(content);
};
return {
getDefaults: function () {
return defaults;
},
hide: function () {
hideModal();
},
show: function () {
showModal();
},
updateTitle: function (title) {
updateModalTitle(title);
return this;
},
updateBody: function (body) {
updateModalBody(body);
return this;
}
}
});
Usage :
var emailModal = new BootstrapModal({modalId: "#confirmModal"});
emailModal.updateTitle("Mail sent successfully").updateBody("<br/>This box will automatically close after 3 seconds.").show();
// Hide the Modal
emailModal.hide();
HTML Structure for the Modal:
<div class="modal fade" id="confirmModal" role="dialog" aria-labelledby="thankyouModal" aria-hidden="true" style="overflow-y: hidden;">
<div class="modal-dialog" style="padding-top: 225px">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-label="Close"><span
aria-hidden="true">×</span></button>
<h4 class="modal-title" id="thankyouModal">Thank you</h4>
</div>
<div class="modal-body">
Thank you. We'll let you know once we are up.
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>

The way I got around this is by loading the data in from external files. So you'd have your initial declaration of your modal box (just the surrounding div), and then in each file you have the containing code for the rest of the modal, then use a bit of jQuery to fire them off:
HTML (in main file)
<div class="modal" id="modal-results" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
</div>
JQuery
$('#create-contact').click(function(){
e.preventDefault();
$("#modal-results").html('create-contact.html');
$("#modal-results").modal('show');
});
