How to check if filename contains substring in JavaScript?
This question already has an answer here:
if you have the file names you can use something like:
if(theFileName.indexOf('myfilethree') > -1)
{
do your magic here because "myfilethree" is present in the name!
}
However, I am not aware of any way to read a directory index in javascript.
There are two parts to this: getting a list of files in a directory, and then searching them for a substring. I'll start with the sceond part, because that's easiest. Simply use indexOf to check for the desired string. If the result of indexOf is not equal to -1, you have a match:
if (filename.indexOf("myfilex") != -1) {
// whatever you want to do
}
As to actually retrieving a list of files, you will need to use Windows Script Host and JScript. See this question for details on that.
var str = 'myfilethree';
if (str.toLowerCase().indexOf("myfilethree") >= 0)
{
alert('File Found');
}
