我想比较两者的电子邮件ID。并希望获得1个数组中的公共电子邮件ID，并从deviceContactEmail中停留在一个数组中。
我尝试了角度。每一个都没有成功。
var wUser = [];
var nonWUser = [];
angular.forEach(deviceContactEmail, function(phonevalue){
console.log(phonevalue);
angular.forEach(friendemail, function(value){
if (phonevalue.emails) {
if(phonevalue.emails[0].value === value.emailId){
console.log(phonevalue.emails[0].value);
wUser.push(phonevalue);
}else{
console.log("------------------------------------------------------------------------");
console.log(phonevalue.emails[0].value);
nonWUser.push(phonevalue);
};
}
})
})

Hi Try this I solved to remove the duplicates value in the array check it...
var wUser = [];
var nonWUser = [];
angular.forEach(deviceContactEmail, function(phonevalue){
console.log(phonevalue);
angular.forEach(friendemail[0].data.userList, function (value) {
if (phonevalue.emails) {
if(phonevalue.emails[0].value === value.emailId){
console.log(phonevalue.emails[0].value);
wUser.push(phonevalue);
}
else {
console.log("------------------------------------------------------------------------");
console.log(phonevalue.emails[0].value);
if ($scope.nonWUser.length == 0) {
nonWUser.push(phonevalue);
}
var filteredVal= $scope.nonWUser.filter(function (filterValue) {
return filterValue.emails[0].value == phonevalue.emails[0].value;
});
if (filteredVal.length == 0)
nonWUser.push(phonevalue);
}
}
});
});

似乎你没有将内循环指向正确的列表。 friendemail是一个列表，但只包含一个项目。我假设您正在测试的emailId被隐藏在数据中，这些数据恰好是friendemail的子项。请尝试以下代码
angular.forEach(deviceContactEmail, function(phonevalue) {
console.log("................ ",phonevalue, " ", friendemail[0].data.userList.length);
angular.forEach(friendemail[0].data.userList, function(value) {
if (phonevalue.emails) {
if (phonevalue.emails[0].value === value.emailId) {
console.log(phonevalue.emails[0].value);
wUser.push(phonevalue);
} else {
console.log("------------------------------------------------------------------------");
console.log(phonevalue.emails[0].value);
nonWUser.push(phonevalue);
}
;
}
})
})
