Append param on loop javascript

Question

I have a function that has a menu param

removeChildCheck:function(menu){
    let removeArrayValues = [];
       for(var i=0; i < this.checkbox.menu.length; i++){
           removeArrayValues.push(this.checkbox.menu[i].value);
       }
       this.user.permissions = this.user.permissions.filter((i) => !removeArrayValues.includes(i));
 },

when I used it like this removeChildCheck('dashboard') im getting length of undefined.

How can I append the param and loop on it? TIA

Do you mean to do:

this.checkbox[menu]

That is, access the property of checkbox that has the name stored in the variable menu? Keep in mind that:

this.checkbox.dashboard

is equivalent to

this.checkbox['dashboard']

and

menu = 'dashboard'
this.checkbox[menu]

As audiodude says, use array syntax: this.checkbox[menu].length

removeChildCheck:function(menu){
    let removeArrayValues = [];
       for(var i=0; i < this.checkbox[menu].length; i++){
           removeArrayValues.push(this.checkbox[menu][i].value);
       }
       this.user.permissions = this.user.permissions.filter((i) => !removeArrayValues.includes(i));
 },
