Javascript Key Codes for Keyboard Characters || javascript function for clicking enter key on keyboard

When we use keyboard keys in your JavaScript function then the following codes will be useful to write condition statement in your function.

We have one textbox and button for login for that you type your username in textbox then instead of clicking Login button if you click on enter key in your keyboard then it has to be login.

For  that the following function will work in onkeypress event.

The enter key value is 13.

<input type="text" id="txtSearch" onkeypress="searchKeyPress(event);" />
    <input type="button" id="btnSearch" Value="Search" onclick="anyfunction();" />

    <script>
    function searchKeyPress(e)
    {

        if (typeof e == 'undefined' && window.event) { e = window.event; }
        if (e.keyCode == 13)
        {
            document.getElementById('btnSearch').click();
        }
    }
