$scope.ptArray={m1 : $scope.somevalue1,
m2 : $scope.somevalue2,
m3 : $scope.somevalue3};
$scope.errMsg={m1 : 'msg1',
m2 : 'msg2',
m3 : 'msg3'};
if($scope.ptArray.this==""){
alert($scope.errMsg.this);
}
'this' is not functioning correctly in this context. Substituting 'this' with m1, m2, or m3 will work, but only for that specific variable. What should be used in place of this?
To achieve this, you can follow these steps:
First, retrieve all the keys that have an empty string value:
var emptyKeys = [];
Object.keys($scope.ptArray).forEach((key) => {if(ptArray[key] == ""){emptyKeys.push(key);}});
Next, display an alert containing the messages for all those keys:
var alertMessage = "";
emptyKeys.forEach((key) => {alertMessage += $scope.errMsg[key] + "\n";});
if(alertMessage.length > 0){
alert(alertMessage);
}
Alternatively, you can combine these actions within a single loop:
var alertMessage = "";
Object.keys($scope.ptArray).forEach((key) =>
{
if(ptArray[key] == ""){
alertMessage += $scope.errMsg[key] + "\n";
}
});
if(alertMessage.length > 0){
alert(alertMessage);
}
When looking to access the dictionary, you can utilize the following code snippet:
if($scope.ptArray[str]==""){
alert($scope.errMsg[str]);
}
Here, the variable str holds a String value of 'm1', 'm2', or 'm3'.
However, using an array might be a more efficient choice:
if($scope.ptArray[index]==""){
alert($scope.errMsg[index]);
}
Here, index is an integer value.
The purpose of this is unclear to me.
Give this a shot
$scope.productArray={n1 : $scope.itemOne,
n2 : $scope.itemTwo,
n3 : $scope.itemThree};
$scope.errorMessage={n1 : 'error1',
n2 : 'error2',
n3 : 'error3'};
Object.keys($scope.productArray).forEach(function(key){
if($scope.productArray[key]==""){
console.log($scope.errorMessage[key]);
}
});
