I have a JSON object jobj=JSON.parse(jsnstr) array returned by JSON.parse and I wish to sort it by its name. I have used
jobj=$(jobj).sort(sortfunction);
function sortfunction(a,b){
return a.name.toLowerCase() > b.name.toLowerCase() ? 1 : -1;
};
But this didnt work out instead i am getting undefined obj any help?
You can't sort a hash; it must be an array. What you can do is setup the reference of each a.name value to an array and then sort that array with a custom function like you have up there.
json = JSON.parse(...);
var refs = [];
for(var i in json) {
var name = i.name;
refs.push({
name : name.toLowerCase(),
object : i
});
}
var sorted = refs.sort(function(a,b) {
return a.name > b.name;
});
Now everything in your refs array is sorted and you can access each object individually by sorted[index].object.
I think you meant to write this:
jobj=$(jobj).sort(function(a,b){
return a.name.toLowerCase() > b.name.toLowerCase() ? 1 : -1;
});
You don't need jQuery for this. Also, sort modifies the original array. So, if jobj is an array, you can just do:
jobj.sort(sortfunction);
You may also want to account for the case where a.name and b.name are the same:
function sortfunction(a,b){
var aSort = a.name.toLowerCase(),
bSort = b.name.toLowerCase();
if(aSort === bSort) return 0;
return aSort > bSort ? 1 : -1;
}
jsnstrlooks like?
