AS3-RegExp姝ｅ垯琛ㄨ揪寮
Some demos about RegExp in AS3:
1.Check input string is Integer or not.
Core codes:
function isInteger(_char:String) {
if (_char==null) {
return false;
}
_char=trim(_char);
var pattern:RegExp=/^[-\+]?\d+$/;
var rs:Object=pattern.exec(_char);
if (rs==null) {
return false;
}
return true;
}
2.function trim()
Core codes:
function trim(_char:String) {
if (_char==null) {
return null;
}
return rtrim(ltrim(_char));
}
function rtrim(_char:String) {
if (_char==null) {
return null;
}
var pattern:RegExp=/^\s*/;
return _char.replace(pattern,'');
}
function ltrim(_char:String) {
if (_char==null) {
return null;
}
var pattern:RegExp=/\s*$/;
return _char.replace(pattern,'');
}
