This is out of the scope of jslinq. What you are looking for is a "startsWith" method for JavaScript strings. A simple Google search will yield many results.

Project Description
LINQ to JavaScript (JSLINQ) is LINQ to Objects for JavaScript arrays, and adds power and flexibility of LINQ style queries to traditional JavaScript code.

What is LINQ to JavaScript?

Nuget Package

http://nuget.org/packages/jslinq

If you don't know what LINQ is; it's a new featureset in the .NET Framework 3.5 that allows more SQL-like querying of any kind of data. In the case of LINQ to JavaScript, it provides the ability to query against Arrays.

var myList = [
            {FirstName:"Chris",LastName:"Pearson"},
            {FirstName:"Kate",LastName:"Johnson"},
            {FirstName:"Josh",LastName:"Sutherland"},
            {FirstName:"John",LastName:"Ronald"},
            {FirstName:"Steve",LastName:"Pinkerton"}
            ];
            
var exampleArray = JSLINQ(myList)
                   .Where(function(item){ return item.FirstName == "Chris"; })
                   .OrderBy(function(item) { return item.FirstName; })
                   .Select(function(item){ return item.FirstName; });

Using LINQ to JavaScript

We will use this Array for the following examples:

var myList = [
            {FirstName:"Chris",LastName:"Pearson"},
            {FirstName:"Kate",LastName:"Johnson"},
            {FirstName:"Josh",LastName:"Sutherland"},
            {FirstName:"John",LastName:"Ronald"},
            {FirstName:"Steve",LastName:"Pinkerton"}
            ];

Create an Instance of the JSLINQ object with your data

You need to create a new JSLINQ object and pass it the javascript array of data that you will be querying.

var example = JSLINQ(myList);

Using the Where operator to specify query criteria

In this case, we're getting all items in the Array that have FirstName property set to Chris.

var whereExample1 = JSLINQ(myList).
                      Where(function(item){ return item.FirstName == "Chris"; });

Using the Select operator to specify which data to return

In this case, we're going to return only the FirstName property of each item in the Array.

var selectTest2 = JSLINQ(myList).
                Select(function(item){ return item.FirstName; });

Using the OrderBy operator to determine how to sort the order of the items in the Array

In this case, we're going to order them by the FirstName property.

var sortTest1 = JSLINQ(myList)
             .OrderBy(function(item){ return item.FirstName; });

Updated Release: v2.00 (Mar 30, 2009)

crpietschmann — Sat, 16 Mar 2013 15:15:53 GMT

This release will include at minimum all the functionality v1.03 has except for the following changes:

Removed use of "eval" method for improved security
Added an example of search an HTML DOM Table using JSLINQ
Placed all functionality within the global JSLINQ object. This is to improve possible compatibility with other javascript frameworks (like jQuery and ASP.NET AJAX).

Released: v2.00 (Mar 30, 2009)

Release Notes

This release includes the below changes, one of which is the most notable is it now includes a "plugin" model similar to that of jQuery. An Extensibility example is included in the download.

Version 2.10 Change Log
- Modified the JSLINQ object to allow you to create an instance of JSLINQ containing an Array of elements
using either of the following methods:
var option1 = JSLINQ(myArray);
var option2 = new JSLINQ(myArray);

- Added an extensibility example; located at "/Examples/Extensions/get.htm"
- Added Improved Intellisense Support and moved it to the "JSLINQ-vsdoc.js" file.

Created Issue: Distinct function not working properly with an object [9775]

baywet — Sat, 08 Dec 2012 22:24:46 GMT

I made a fix!
We assume that if the programmer doesn't want a distinct on a base type collection he just uses a clause to help knowing how to compare them.
Enjoy

Distinct: function (clause) {
var item;
var dict = new Object();
var retVal = new Array();
for (var i = 0; i < this.items.length; i++) {
item = this.items[i];
if ((clause == null && dict[item] == null) || (clause != null && dict[clause(item)] == null)) {
if (clause == null)
dict[item] = true;
else
dict[clause(item)] = true;
retVal[retVal.length] = item;
}
}
dict = null;
return new JSLINQ(retVal);
},

Is there any wildcard available in the product? How are we able to run a query like

Select Employees.Name from Employees where Employees.Name like 'S%' (returns all employees which their name starts with S)

What is LINQ to JavaScript?

LINQ to JavaScript (JSLINQ for short) is an implementation of LINQ to Objects implemented in JavaScript. It is built using a set of extension methods built on top of the JavaScript Array object. If you are using an Array, you can use JSLINQ.

If you don't know what LINQ is; it's a new featureset in the .NET Framework 3.5 that allows more SQL-like querying of any kind of data. In the case of LINQ to JavaScript, it provides the ability to query against Arrays.

var myList = [
            {FirstName:"Chris",LastName:"Pearson"},
            {FirstName:"Kate",LastName:"Johnson"},
            {FirstName:"Josh",LastName:"Sutherland"},
            {FirstName:"John",LastName:"Ronald"},
            {FirstName:"Steve",LastName:"Pinkerton"}
            ];
            
var exampleArray = JSLINQ(myList)
                   .Where(function(item){ return item.FirstName == "Chris"; })
                   .OrderBy(function(item) { return item.FirstName; })
                   .Select(function(item){ return item.FirstName; });

Using LINQ to JavaScript

We will use this Array for the following examples:

var myList = [
            {FirstName:"Chris",LastName:"Pearson"},
            {FirstName:"Kate",LastName:"Johnson"},
            {FirstName:"Josh",LastName:"Sutherland"},
            {FirstName:"John",LastName:"Ronald"},
            {FirstName:"Steve",LastName:"Pinkerton"}
            ];

In this case, we're going to return only the FirstName property of each item in the Array.

var selectTest2 = JSLINQ(myList).
                Select(function(item){ return item.FirstName; });

In this case, we're going to order them by the FirstName property.

var sortTest1 = JSLINQ(myList)
             .OrderBy(function(item){ return item.FirstName; });
