function demo() {
var test = [{
level: 19,
title: "hello1"
}, {
level: 2,
title: "hello2"
},
{
level: 5,
title: "hello5"
}];
I want to sort this array but can't find a way to do so.
You can create a custom sorting function:
// Sort by level
test.sort(function(a, b) {
return a.level - b.level;
});
Resulting object:
[
{"level":2,"title":"hello2"},
{"level":5,"title":"hello5"},
{"level":19,"title":"hello1"}
]
You can create a sort function like:
function sortBy(prop){
return function(a,b){
if( a[prop] > b[prop]){
return 1;
}else if( a[prop] < b[prop] ){
return -1;
}
return 0;
}
}
//Usage
var test = [{
level: 19,
title: "hello1"
}, {
level: 2,
title: "hello2"
},
{
level: 5,
title: "hello5"
}].sort( sortBy("level") );
Please check below code ,
<script type="text/javascript">
var test = [
{ level: 19, title: "hello1" },
{ level: 2, title: "hello2"},
{ level: 5, title: "hello5" }
];
// Before Sorting
document.write("<b>Before Sorting </b><br/>");
for (var n = 0; n < test.length; n++) {
document.write(test[n].level + ' ' + test[n].title+ '<br>');
}
// ascending order
function SortByLevel(x,y) {
return x.level - y.level;
}
function SortByTitle(x,y) {
return ((x.title == y.title) ? 0 : ((x.title> y.title) ? 1 : -1 ));
}
// Call Sort By Name
test.sort(SortByTitle);
document.write("<br/><b>After Sorting </b> <br/>");
for(var n=0;n<test.length;n++){
document.write(test[n].level + ' ' + test[n].title+ '<br>');
}
</script>
