php - checking json array with my value to do operation otherwise other operation -


consider have json array this

 ["map14","map20","map21","map22","map23","map24","map25","map31","map32","map33","map34","map35","map36","map37","map40","map41","map42","map46","map49","map50"]

with json array need check if passed value exists need operation or otherwise other operation....

javascript code:

function pop(e,id) {  $.getjson( 'layoutcheck.php', { some_get_var: 1 }, function(output){     var i=0, total = output.length;     ( = 0; < total; ++i ) { if(isarray(output[i]==id)) {  // soome stuff if value exists in database       } else{ // if not exists other operation  }     } }); } </script>

layoutcheck.php fetch information database , create json array..

but code fails display output.. please rectify me ..

thanks

isarray() won't check if object in array, if object array.

this means output[i]==id (which either true or false) checked. not arrays; meaning you'll go else part of condition.

you can try using like:

if(output.indexof(id) != -1) {     // soome stuff if value exists in database } else{     // if not exists other operation }

instead of for loop.
