I am working with three arrays:
arr1=["14","16","1"] — this is where I make my selectionarr2=["14"] — this is where I compare my selection from arr1arr3=[] — this array stores the values that meet the conditionsHow can I check if the selected value does not exist in arr2?
For instance, if I select 14 from arr1 and it already exists in arr2, the button should be disabled and the value should not be added to arr3.
Here's a question related to JavaScript, rather than AngularJS. See if this helps:
If the element "14" is not already in arr2, add it to arr3.
if(arr2.indexOf("14") == -1){
arr3.push("14");
}
