I have array like this:
a = [{"province":"Western"},{"province":"Central "},{"province":"Southern "}]
in javascript. I want to extract all province and put it as in data as mentioned below.
data: [{id: 'province1', text: 'province1'},{id: 'province2', text: 'province2'},
{id: 'province3', text: 'province3'}]
I tried it with for loop.
for (index = 0; index < a.length; ++index) {
console.log(a[index]);
}
But, it's giving me character values..
You can build the ids by concatenating a string with a numeric id:
"province" + index // "province1"
Summing up
var data = [];
for (index = 0; index < a.length; ++index) {
data[index] = { id: 'province' + (index+1), text: a[index].province} ;
}
var a = [{"province":"Western"},{"province":"Central "},{"province":"Southern "}], b = {};
for(var i = a.length; i--; b[a[i].province] = a[i].province);
console.log(b);
Result is
{Southern : "Southern ", Central : "Central ", Western: "Western"}
Edit as per the comment:
var a = [{"province":"Western"},{"province":"Central "},{"province":"Southern "}];
a = a.map(function(v){
return { id : v.province, text : v.province };
});
console.log(a);
