javascript - Sorting a JSON object excluding an item -

-

i have json object follows:

[     {"at&t" : "blocked"},     {"all" : "targeted"},     {"verizon" : "blocked"},     {"sprint" : "blocked"} ]

which sort alphabetically using following function:

sortbykey : function(array, key) {         return array.sort(function(a, b) {             var x = a[key]; var y = b[key];             return ((x < y) ? -1 : ((x > y) ? 1 : 0));         });     },

this works fine. want exclude {"all" : "targeted"} sorting , have first element of json object so:

[    {"all" : "targeted"},    {"at&t" : "blocked"},    {"sprint" : "blocked"}    {"verizon" : "blocked"},  ]

could give me hint of on how can achieved? i'll need way exclude item json object sorting , set first element of object.

thanks in advance!

if want exclude value, eg keep @ top of sort, whenever sort function encounters return -1 if first argument or 1 if second

//keep 2 @ front [1,254,6,2,62].sort(function(a,b){   if(a == 2) return -1; else if(b == 2) return 1;   return a-b; });  [2, 1, 6, 62, 254]  //keep 2 @ [1,254,6,2,62].sort(function(a,b){   if(a == 2) return 1; else if(b == 2) return -1;   return a-b; });  [1, 6, 62, 254, 2]
