Javascript: Remove last character if a colon

rated 0 times [ 154] [ 4] / answers: 1 / hits: 90648 / 12 Years ago, mon, september 3, 2012, 12:00:00

Relative newcomer to Javascript and looking for a way to remove the last character of a string if it is a colon.

I know myString = myString.replace('/^\:/'); will work for the start of the line but not sure how to swap in the $ character to change to the end of a line… can anybody correct it?

Thanks

The regular expression literal (/.../) should not be in a string. Correcting your code for removing the colon at the beginning of the string, you get:

myString = myString.replace(/^:/, '');

To match the colon at the end of the string, put $ after the colon instead of ^ before it:

myString = myString.replace(/:$/, '');

You can also do it using plain string operations:

if (myString.charAt(myString.length - 1) == ':') {

  myString = myString.substr(0, myString.length - 1);

}
