angularjs - Getting the subject line in gmail api - javascript -

i'm trying subject line email using gmail api. have email , tried following documentation. array of headers place holder subject line different in each email.

how can subject header back?

right i'm specifying element in array so:

var parsed5 = resp.payload.headers[1].name;

however don't want have specify element of area, there way right stuff based on header name instead of element?

you can find subject :

for (var headerindex = 0; headerindex < resp.payload.headers.length; headerindex++) {                 if (resp.payload.headers[headerindex].name == 'subject') {                     relatemaildetail.openmailsubject = msg.payload.headers[headerindex].value;                 }                 if (resp.payload.headers[headerindex].name == 'from') {                     relatemaildetail.from = msg.payload.headers[headerindex].value;                 }                 if (resp.payload.headers[headerindex].name == 'date') {                     relatemaildetail.recievedate = msg.payload.headers[headerindex].value;                 }                 if (resp.payload.headers[headerindex].name == 'to') {                     relatemaildetail.to = msg.payload.headers[headerindex].value;                 }                 if (resp.payload.headers[headerindex].name == 'cc') {                     relatemaildetail.cc = msg.payload.headers[headerindex].value;                 }                 if (resp.payload.headers[headerindex].name == 'reply-to') {                     relatemaildetail.replyto = msg.payload.headers[headerindex].value;                 }             }
