remove all items in array that start with a particular string

Hi let’s say that I have an array like this in javascript:

var arr = ["ftp_text_1", "abc_text_2", "ftp_text_3"];

How do I remove from all the strings from my array that start with ftp_

Thanks

Answer

Simply use Array.filter:

arr = arr.filter(function (item) {
   return item.indexOf("ftp_") !== 0;
});

Edit: for IE9- support you may use jQuery.grep:

arr = $.grep(arr, function (item) {
   return item.indexOf("ftp_") !== 0;
});
