Looping the list of values in element.io table. I need to display the sum of list of weights. I am unable to sum all the weight values.
var val= [
{
"NmVehiclePlanning.deliveryBranch": "Madurai",
"NmVehiclePlanning.deliveryCity": "Madurai",
"NmVehiclePlanning.weight": 30106
},
{
"NmVehiclePlanning.deliveryBranch": "Madurai",
"NmVehiclePlanning.deliveryCity": "Virudhunagar",
"NmVehiclePlanning.weight": 3498
},
{
"NmVehiclePlanning.deliveryBranch": "Madurai",
"NmVehiclePlanning.deliveryCity": "KANYAKUMARI",
"NmVehiclePlanning.weight": 500
}, ]
The above data is my json data. Need to sum of all (Key name: NmVehiclePlanning.weight)
<el-table-column label="weight">
<template slot-scope="scope">
<span v-for="data in scope.row.details">
{{ data['NmVehiclePlanning.weight'] }}
</span>
</template>
</el-table-column>
Received value is
30106 3498 500
Expected value is
34104

Try with this. Hope it will work
<el-table-column label="weight">
<template slot-scope="scope">
{{ calculateSum(scope.row.details) }}
</template>
</el-table-column>
Add this function in your script.
calculateSum(val){
var sum = 0;
for(let value in val){
sum += val[value]['NmVehiclePlanning.weight']
}
return sum;
},

I think you need to calculate this value in your javaScript and then display the sum.
calculateSum(){
var sum = 0;
for(let value in val){
sum += value['NmVehiclePlanning.weight']
}
return sum;
}
