Hello:
Similar question has been asked here: How to pass a regular
expression as a function parameter
<http://stackoverflow.com/questions/11143702/how-to-pass-a-regular-expression-as-a-function-parameter>,
but I can't get it work by JSNI.
This is the string of the regular expression that will be used to test
email:
|
"^(([^<>()[\]\\.,;:\s@\"]+(\.[^<>()[\]\\.,;:\s@\"]+)*)|(\".+\"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$"
|
and if putting it to firebug execute like this:
|
/^(([^<>()[\]\\.,;:\s@\"]+(\.[^<>()[\]\\.,;:\s@\"]+)*)|(\".+\"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$"/.test("[email protected]")
|
it will give what I want,but If wrapping it to a JSNI method:
| private native boolean reEmail()/-*{
return
"^(([^<>()[\]\\.,;:\s@\"]+(\.[^<>()[\]\\.,;:\s@\"]+)*)|(\".+\"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$";
}-*/;
|
then passing it to the function:
| private native boolean validate(String value, String regexp)/-*{
//escape special characters
var re=regexp.replace(/([-()\[\]{}+?*.$\^|,:#<!\\])/g,
'\\$1').replace(/\x08/g, '\\x08');
return new RegExp(re,'g').test(value)
}-*/;
|
like this:
| validate("[email protected]",reEmail());
|
It will give me false.Please tell what mistakes I have made,thanks.
