You can search for a value in an array using the custom find function-
// Code Sample: User Interface
inputfield ([2,4], "Taxable State", [2,18],{"name":"z_state", "size":2});
pushbutton([4,4], "Validate State",{"size":[1,15], "process":validate_state});
//Array with values
var stateArray = ["AK","FL","NV","NH","SD","TN","TX","WA","WY"]; // Non taxable states
// Function to return true or false if the search element is found in the array
Array.prototype.find = function (p){
for(i=0;i<this.length;i++) if(this == p) return true;
return false;
}
//Function to check the value
function validate_state(){
if(stateArray.find(z_state)){
return('E: Please enter taxable state');
}
}
