I am getting a string an array of objects field from the data base which contains a value like:dataarray=[{name:'xyz',id:' '},{name:'abc',id:'DOC-TEMP-1'},{name:'efg',id:''},{name:'abc',id:'DOC-TEMP-21'},{name:'abc',id:''},{name:'jklm',id:'DOC-TEMP-2'}];.
I want to sort this array based on id so i tried to do it using sort method like this:
dataarray.sort(function(a,b){
var a1 = a['id'].split('-');
var b1 = b['id'].split('-');
console.log('value in a1: '+a1);
console.log('value in b1: '+b1);
if(a1[2] =='' || a1[2]==null)
{
a1[2] == 0;
}if(b1[2]=='' || b1[2]==null)
{
b1[2] == 0;
}
return a1[2]-b1[2];
});
But it gives me uncorrect result.
what i want is it should first show the null ids then the id sort by number .
How can i do this ?
