Javascript if string contains a space replace the space with a dash

Question

I'm trying to write some code that will check if a previously defined variable has a space, and if it does, replace the space with a dash. This will be nested in another function.

function foo(){            
    // If stateName has a space replaces the space with a dash

    window.open('http://website.html/state-solar-policy/' + stateName);
}

Answer 1

Use this regex:

stateName.replace(/\s/g,"-");

It will replace all white spaces chars with a dash (-)

Note that the regex will cause no troubles if the string doesn't have a space in it.
It replaces every white-space if finds with a dash, if it doesn't find, it does nothing.
