I have an object coming from upload
obj: {
name: 'Mike'
street: 'Love'
}
and I can loop through it via
<div v-for="test in obj">
<span>{{test.name}}, {{test.street}}</span>
</div>
and I get fine output.
However, the object keys became different depending on user upload, sometimes the key will become
obj: {
address: 'street test 123',
fine: '32 PHP',
magic: 'Love'
}
How can I loop through it to become dynamic?
you have to take all keys in one array then you can bind it.
obj: {
address: 'street test 123',
fine: '32 PHP',
magic: 'Love'
}
var keys = Object.keys(obj);
<div>
<span>{{keys.join(,)}}</span>
</div>
You can just loop through the whole object like this, here index
is the variable name and item
is the value
var app4 = new Vue({ el: '#app-4', data: { obj: { address: 'street test 123', fine: '32 PHP', magic: 'Love' } } })
<script src="https://unpkg.com/vue/dist/vue.js"></script> <div id="app-4"> <div v-for="(item, index) in obj"> <span>{{item}}</span> </div> </div>
I don't think you want to use v-for
for this purpose.
This is what I would do without changing how you have your obj
set up:
<div id="foo">
{{computedVal}}
</div>
and in the Vue
instance,
new Vue({
data: {
// ... miscellaneous stuff
obj: {
prop1: 'val1',
prop2: 'val2',
prop3: 'val3',
}
},
methods:{ /* ... */ },
computed: {
computedVal(){
let str = '';
for(let key in this.obj){
let val = this.obj[key];
str += `<span>${key} : ${val}</span>`;
}
return str;
}
}
});
This will be your output:
<div id="foo">
<span>prop1 : val1</span>
<span>prop2 : val2</span>
<span>prop3 : val3</span>
</div>
Of course you can do this inside v-for
as well.
My understanding is that as of now, Vue doesn't do object property iteration inside v-for
.
