Regular Expression to exclude a specific string

[dragon6158]

I have been trying to come up with a Regular Expression that would exclude the string "Select Router Type". Any help would be appreciated.

Thanks,
Don

To "exclude" something from a string you need a method. And the RegExp method is replace()

myString=myString.replace(/Select Router Type/g,'');

or dynamically:

var reg=new RegExp('Select Router Type','g');
myString=myString.replace(reg,'');

is this what you are looking for?

Unfortunately no, we are using the regular expression as a means of error checking and the reason I am excluding that string is because that is what I am defaulting my variable to so it is automatically an error. Thanks for the advice though.

Can you detail?

My supervisor has written some code in a CSS that checks to see if a regular expression returns a true or false condition and changes the color around the variable depending on that condition, ie: if a regular expression is used to check an IP address and the user inputs something that is not a valid IP address, the variable is turned red to tell the user that they messed up.

This is how we use it:

testREG((/Select/),this.value).

This statement tests the value in an input box and returns true or false and turns the variable red or green wherever it is used.

aha... to exclude something from a regular expression evaluation the [^ ... ] characters are to be used. See the link I have posted to you.

Here are the latest ones that I've tried:

testREG((/^"Select Router Type"/),this.value)

testREG((/^Select Router Type/),this.value)

and neither one works.

what is testREG()? A custom function?

[dragon6158]

Yes it is

[dragon6158]

This is the testREG function:


function testREG(regexp2,text2) {
if (regexp2.test(text2)) {
return true;
}
return false;}

Kor,
Thanks for your help. My supervisor changed his mind about how he wanted it done which made it a lot simpler.
