Question

Hey all, i want to use a regular expression to match a word with one specified character randomly placed within it. I also want to keep that ‘base’ word’s characters in their original order.

For example, with the ‘base’ word of test and the specified character of 'y', i want the regular expression to match all the following, and ONLY the following: ytest, tyest, teyst, tesyt, testy

Incase it matters, im working in javascript and using the dojo toolkit.

Thanks!

Does it have to be Regex? If not will this do?

function matches(testWord, baseWord)
{
    for (var i =0; i < testWord.length; i++)
    {
    if(testWord.substr(0,i) + testWord.substr(i+1,testWord.length- i) == baseWord)
        return true;
}

return false;
}
