How do I filter items in an array based on a substring match?

Question

I am searching an array in jQuery,

var arr = ["mango","banana","jackfriut","apple","google"];
var removeItem = "google";   //works fine
var removeItem = "ogle";   //fails

arr = $.grep(arr, function(value) {
  return value != removeItem;
});
alert(arr)

When I am passing "google" then its working fine. Please let me know that it should work when I pass only some content like "ogle". its like wildcard.

You can use indexOf for your condition

 var arr = ["mango","banana","jackfriut","apple","google"];
 var removeItem = "ogle";   //fails

 arr = $.grep(arr, function(value) {
    if(value.indexOf(removeItem) == -1)
       return value;
 });
 alert(arr)

JSFiddle

Hope it helps :)

You can use jQUery's built in $.inArray function.

var arr = ["mango","banana","jackfriut","apple","google"];

function inArray() {
    if($.inArray(value, arrayName) !== -1) {
        alert("Value is in array");
    } else {
        alert("Value is not in array");
    }
}

You can then call your function passing in the value you are looking for:

inArray("google");

Of course, the logic you choose to return in the function is up to you but this is the best way to check for values in an array.
