regex case insensitivity

Question

How would I make the following case insensitive?

if ($(this).attr("href").match(/\.exe$/))
{
// do something
}

Answer 1

Put an i after the closing slash of the regex.

So your code would look like this:

if ($(this).attr("href").match(/\.exe$/i))

Answer 2

With /i modifier:

if ($(this).attr("href").match(/\.exe$/i))
{
// do something
}

Answer 3

if ($(this).attr("href").match(/\.exe$/i))
{
// do something
}

Answer 4

Another option would be to simply manipulate the case to what you want.

It appears as though you are trying to match against lowercase characters.

So you could do this:

if ($(this).attr("href").toLowerCase().match(/\.exe$/)) {
     // do something
}

In fact, you could use .indexOf() instead of a regex if you wanted.

if ($(this).attr("href").toLowerCase().indexOf('.exe') > -1) {
     // do something
}

Of course, this would match .exe in the middle of the string as well, if that's an issue.

Finally, you don't really need to create a jQuery object for this. The href property is accessible directly from the element represented by this.

if ( this.href.toLowerCase().match(/\.exe$/) ) {
     // do something
}
