在具有连接名称的对象中添加元素

Question

I have object $scope.form . I want to add various elements in it as $scope.form.elem1, $scope.form.elem2, $scope.form.elem3 and so on.

I tried some ways but nothing worked for me.

for(i = 0; i <= addr.length; i++) {
  $scope.form.elem = addr.i; //What should be here ??
}

Answer 1

$scope.form["text"+variable] = addr[i];

Use brackets [] when you want to access a property with either a variable value, concatenated string or string with abnormal characters like "." .

Answer 2

Assume you have the values in array addr .
You can iterate the object properties with a string like this.

for (let i = 0; i < addr.length; i++) {
   $scope.form['yourName' + i] = addr[i];
}

Answer 3

Are you looking like this :

var noOfelements = 100; // you can have your addr array also 
var key;
for(i = 1; i <= noOfelements; i++) {
 key = "elem"+i;
 $scope.form[key] = i; //i is just for reference you can give value to each element as per your need
}

below is the output you will get the same output with $scope also.
