popUp.js

function popUp(t, m, pp){

// intialization of return value
var ret;

/*
var m is the message in the popup (required)
var t is the type of popup (required)
var pp sets a placeholder for the input (prompt only)

possible values of t: "alert", "confirm", "prompt" (include the quotation marks)
any value of m and pp must be enclosed within quotation marks
*/

//show message
if (t=="alert"){alert(m);}

//get confirmation (returns "true" or "false") and get value
else if(t=="confirm"){r=confirm(m);}

//get prompt (setting pp is optional) and get value
else{r=prompt(m, pp);}

//return value if t is "confirm" or "prompt"
if(t=="confirm"||t=="prompt"){ret=r;}

//return nothing if t is "alert"
else{ret=""}

//final return value of function
return ret;
