javascript - inserting into json array in js/angularjs -

i have json array

var testarr=[{name:"name1",age:20},{name:"name1",age:20},{name:"name1",age:20}]   

how insert item "uid" testarr looks this

var testarr=[{name:"name1",age:20,uid:1},{name:"name1",age:20,uid:2},{name:"name1",age:20,uid:3}]  

i have tried following js code seems add @ end

var testarr=[{name:"name1",age:20},{name:"name1",age:20},{name:"name1",age:20}];   var loopcycle = (testarr.length);   for(i=0; < loopcycle ; i++){   testarr.push({uid:i+1}) }     console.log(testarr) 

thanks

your problem here:

testarr.push({uid:i+1}) 

for each element in array, creating new element ({uid:i+1}). need access json object , create new property. try this:

var testarr=[{name:"name1",age:20},{name:"name1",age:20},{name:"name1",age:20}];   var loopcycle = (testarr.length);   for(i=0; < loopcycle ; i++){     testarr[i]['uid'] = i+1; }     console.log(testarr); 

if want using angular way, try this:

angular.foreach(testarr, function (x,idx) { x.uid = idx+1; });
