I have a dynamic img being pulled from an api using vue.js. For some strange reason, the image won't bind. I have tried both :src. and :attr but neither works. The url does display in the vue console inside of the data but can't get the image to display on the page. any help will go a long way.
<html>
<head>
<style></style>

<body>
<div class="container">
<div id="editor">
<img v-bind:src="PictureURL" />
</div>
</div>
<script type="text/javascript" src="https://unpkg.com/vue#2.0.3/dist/vue.js"></script>
<script>
new Vue({
el: "#editor",
data: {
PictureUrl: "",
},
created: function() {
this.getCurrentUser();
},
methods: {
getCurrentUser: function() {
var root = 'https://example.com';
var headers = {
accept: "application/json;odata=verbose"
}
var vm = this;
var __REQUESTDIGEST = '';
$.ajax({
url: root + "_api/Properties",
type: 'Get',
headers: headers,
success: function(data) {
vm.PictureUrl = data.d.PictureUrl;
}
})
},
}
})
</script>
</body>
</html>
Change <img v-bind:src="PictureURL" /> to <img v-bind:src="PictureUrl" />, so that you match the data item name. Vue should be giving you an error in the console about this.
https://jsfiddle.net/kch7sfda/
Example here.
You can try to:
1. add v-if to img element
2. rename PictureUrl to pictureUrl (first lowercase letter)

This is the updated code please tell me where I am going wrong

<div id="demo">
<span v-for="(string, index) in lists">

You could use a computed property for this in combination with split:
var demo = new Vue({
el: '#demo',
data: function() {
return {
string: ''
};
},
computed: {
lists: function(){
return this.string.split(",");
}
}
})
I am working on a vuejs repeatable component that will allow a user to due several things---enter a question and select the answer type from the drop down. Issue is based on the type, I need to display a select number of boxes if its multiple choices so it can update an array. I cannot figure out how or where to add this. I also need to make these variable (f1 and f2 dynamic) so that it can be reused at other times. So if its a single line choose f1 if it is multiple choice select f2. Someone please provide some direction
Vue.component('my-input', {
template: '<input v-attr="name: name" v-model="value" type="text">' + '<select>' + '<option value="type1">Multiple Choice</option>' + '<option value="type2">single line</option>' + '<option value="type3">multi-line</option>' + '</select><br>'+'<br>'+'</br>',
data() {
return {
value: '',
brand: 'multiple-choice',
options: ['option a, option b'] };
},
props: ['name'] });
new Vue({
el: '#app',
data: {
message:'',
inputs: [{ type: 'my-input' }]
},
mounted: function () {
this.getAllPages();
},
methods: {
addInput() {
this.inputs.push({ type: 'my-input' });
},

var vm = this;

I don't know if i understand correctly but if you want to pass different data to your component dynamically you can use props.
Take a look here https://v2.vuejs.org/v2/guide/components-props.html
Using Vue.js, how do you use axios GET to display the response in a dialog?
I've tried the following:
<!DOCTYPE html>
<html>
<head>
<title></title>
</head>
<body>
<template>
<label>Protocol</label> Display protocol details from json
<div class="text-xs-center">
<br>
</div>
</template>
<script>
export default {
dialog3: false
created() {
let self = this
axios.get('http://localhost:4000/ap/device')
.then(function(response) {
self.fDModelName(response.data.result)
console.log(JSON.stringify(response.data.result))
})
},
methods: {
fDModelName: function(message) {
console.log("inside")
}
}
}
</script>
</body>
</html>
Create a data object where you have content as a key. On component created, you can assign it to the component's content value.
<template>
<div>
{{ content }}
</div>
</template>
<script>
export default {
data () {
return {
content: []
}
},
created () {
axios.get('http://localhost:4000/ap/device')
.then(function (response) {
this.content = response.data.result
})
}
}
</script>
I am trying to set up multiple returns in a computed property. Not sure why this is not working. I also tried repurposing the arrow function. What I am trying to do here, is when the application loads trigger the 'nearby' method that does a bit of filtering and also trigger the sortedItems method. I tried moving things around but it breaks. Is it possible to call both of these in in the userFilterkey:['nearby', 'someFunc']. I thought it would be cool, but doesn't work. I basically just need to trigger nearby and sortedItems on load.

A function will only reach one return so not sure what you're doing with sortedItems.
You would never be responsible for running nearby yourself. nearby runs whenever items changes. What you can do instead is have a single results computed property and do something like:
computed: {
results () {
return this.items
.filter(...)
.sort(...)
},
},
and use results in your template.
Also:
items.status=="New" | items.status=="in-progress"
should be:
items.status=="New" || items.status=="in-progress"
or even better:
items.status === "New" || items.status === "in-progress"`.
Why does filter do not work?
Error says: [Vue warn]: Failed to resolve filter: uppercase.
Not sure why but filter is not working.
Also, is this the best way to code this functionality? Are there any ways to do this, or the suggested ways? I'm not sure about using the $refs, maybe I can do this simpler, but with effective use of reusable components.
I'm trying to emulate an Ajax Response by using random message and status instead.

The uppercase filter has been removed in Vue.js 2.
https://v2.vuejs.org/v2/guide/migration.html#Built-In-Text-Filters-removed
You can simply use:
{{ text.toUpperCase() }}
As far as the structure of your code goes, something like this is probably better off in a method:
close: function() {
this.alertType= null;
this.title= null;
this.message= null;
this.showAlert= false;
}
Since you are duplicating it twice but just with different values.
