ScriptContext Class

C#, doesn't support global methods, so jQuery's $ function can't be used as simply in Saltarelle as it is in Javascript.

A simple expression like $('#SomeElementId) in Javascript corresponds to Saltarelle C# code jQuery.Select("#SomeElementId").

As a workaround, ScriptContext class can be used:

public class ScriptContext
{
    [InlineCode("$({p})")]
    protected static jQueryObject J(object p);
    [InlineCode("$({p}, {context})")]
    protected static jQueryObject J(object p, object context);
}

As $ is not a valid method name in C#, J is chosen instead. In subclasses of ScriptContext, jQuery.Select() function can be called briefly as J().

public class SampleClass : ScriptContext
{
    public void SomeMethod()
    {
        J("#SomeElementId").AddClass("abc");
    }
}
