I have an array of objects called config
, and a currentIdx
property in my component. Then I found myself needing to do this:
computed: {
textStyle: function() {
return this.config[this.currentIdx].textStyle;
},
text: function() {
return this.config[this.currentIdx].text;
},
key: function() {
return this.config[this.currentIdx].key;
}
}
I tried replacing all functions with:
computed: {
...this.config[this.currentIdx]
}
It passed the compilation, but I got an error in the browser console. I think the problem is that computed
requires functions, but the spread syntax (...) returns objects. So, my question is: Is there any way to reduce the repetition in this case?
Thanks!
Computed values can return objects, they just need to be returned by the function. Let me know if this isn't what you intended and I'll see what I can do to help!
let vm = new Vue({
el : "#root",
data : {
current : 0,
arrs : [
{
color : "background-color: blue;",
text : "Dabodee Dabodai"
},
{
color : "background-color: red;",
text : "Angry"
},
{
color : "background-color: green;",
text : "See it works!"
}
]
},
computed : {
currentObject : function() {
return this.arrs[this.current];
}
}
});
