I want to add "*." at opening and ";" at ending on each array element. Below is the sample code.
var ext = getExt(filename);
var s = '<%=AllowedExtensions %>';
var match = s.split(', ');
In the above code in 'match' I use to get ["jpg", "png", "txt"] like this. So here on each array element I want to prefix with "." and at end of each want to add ";" and also it should give me a string such as ".jpg;.png;.txt;" .
Try this:
var matchString = '.' + match.join(';.') + ';'
ES5 code:
match = match.map(function( word ) {
return '*.' + word + ';';
}).join('');
ES3 code:
for(var i = 0, len = match.length; i < len; i++) {
match[ i ] = '*.' + match[ i ] + ';';
}
match = match.join('');
You can do something like this:
for(var k = 0; k < match.length; k++)
{
match[k] = '*.' + match[k];
}
var allExten = match.join(';');
