B _txt.onChanged = limitToNum;
C_txt.onChanged = limitToNum;
...
It was a little complicated and suddenly remembered 'prototype ':
TextField. prototype. onChanged = function (){
If (this. text! = "-" IsNaN (this. text )){
This. text = '';
}
};
This restricts all dynamic text input boxes in

If any, record the length and obtain the minimum value.Str1 = "daebfacba ";Str2 = "abc ";MinLen = len (str1 );For I = 0: len (str1)For j = I + 1: len (str1)If (isContainAl
