how would you go about replacing the "image" data array in this example with an external JSON file? Basically I want to fetch/get this data externally with axios but something is not quite working yet in this example. Any clue very much appreciated!
I also created a CodePen for this example working without the external reference if you prefer to look at it this way. Thanks a lot! https://codepen.io/FloydGekko/pen/eLoRBQ
This is the html, css and vue.js code:
<head>
<style>
[v-cloak] {
display: none;
}
.imageBlock{
width:100%;
margin:10px;
}
div.polaroid {
width:310px;
height:440px;
margin:10px;
background-color: white;
box-shadow: 6px 4px 8px 0 rgba(0, 0, 0, 0.2), 6px 6px 20px 0 rgba(0, 0, 0, 0.19);
margin-bottom: 25px;
border-radius: 18px
}
div.container {
text-align: center;
padding: 10px 20px;
}
</style>
</head>
<body>
<div id="vue" v-cloak>
<h2 align="center">
Show
<select v-model="currentKind" @change="onChange">
<option v-for="kind, index in kinds" :value="kind" :key="`kind_${index}`">{{kind ? kind : 'kind...'}}</option>
</select>
<select v-model="currentColor" @change="onChange">
<option v-for="color, index in colors" :value="color" :key="`kind_${index}`">{{color ? color : 'color...'}}</option>
</select>
and
<select v-model="currentShape" @change="onChange">
<option v-for="shape, index in shapes" :value="shape" :key="`kind_${index}`">{{shape ? shape : 'shape...'}}</option>
</select>
</h2>
<isotope

// THIS IS THE PART OF THE CODE IN QUESTION I THINK
loadImages: function () {

})
.catch(function (error) {

});
}
},
});

</body>
</html>
And this is the external JSON file "myimagedata.json" I try to load with axios:
{
"images": [
{
"id": 1,
"kind": ["A"],
"color": ["Green", "Blue"],
"shape": ["Square"],
"pic": "http://r.ddmcdn.com/s_f/o_1/cx_462/cy_245/cw_1349/ch_1349/w_720/APL/uploads/2015/06/caturday-shutterstock_149320799.jpg",

"title": "A"
},
{
"id": 2,
"kind": ["B"],
"color": ["Green", "Red"],
"shape": ["Circle"],

}
