Modified tomato Form Verification Code

Once posted on the classic Forum, this is used in personal projects during background processing, which is quite convenient for simple form verification.
Because you don't want to make the code too bloated, you don't need to add more features that are not commonly used.
I have not made any changes to my views. Why? Because I am lazy, haha
Today, we can see that omeweb has also modified a version and made many modifications, which is quite good. Thank you.

The source code is here:

// Remove spaces on both sides of the string
String. prototype. trim = function (){
Return this. replace (/(^ \ s +) | (\ s + $)/g ,"");
}
// Check whether the string is empty
String. prototype. isEmpty = function (){
Return! (/.? [^ \ S] +/. test (this ));
}
// Check whether the value is between two specified values
String. prototype. isBetween = function (val, min, max ){
Return isNaN (val) = false & val> = min & val <= max;
}
// Obtain the maximum or minimum value
String. prototype. getBetweenVal = function (what ){
Var val = this. split (',');
Var min = val [0];
Var max = val [1] = null? Val [0]: val [1];
If (parseInt (min)> parseInt (max )){
Min = max;
Max = val [0];
}

}
