javascript - Call jQuery datepicker from external file -


i'm relatively new jquery , having difficult time getting jquery datepicker work external js file.

originally created script function, believed doing limiting scope , not accessible outside function. i've tried defining function (and naming function), calling using $(document).ready. cannot work either way.

my external js script called scripts.js , contents below:

$( "#from" ).datepicker({     defaultdate: "+1w",     changemonth: true,     changeyear: true,     numberofmonths: 2,     showon: "both",     buttonimageonly: true,     buttonimage: "images/calendar.gif",     dateformat: "mm/dd/yy",     altfield: "#forminp1",     altformat: "yyddmm",     onclose: function( selecteddate ) {         $( "#to" ).datepicker( "option", "mindate", selecteddate );     } }); $( "#to" ).datepicker({     defaultdate: "+1w",     changemonth: true,     changeyear: true,     numberofmonths: 2,     showon: "both",     buttonimageonly: true,     buttonimage: "images/calendar.gif",     dateformat: "mm/dd/yy",     altfield: "#forminp2",     altformat: "yyddmm",     onclose: function( selecteddate ) {         $( "#from" ).datepicker( "option", "maxdate", selecteddate );     }, });

the html is:

<!doctype html> <html lang="en"> <head>     <meta charset="utf-8">     <title>jquery ui datepicker - select date range</title>     <link rel="stylesheet" href="css/jquery-ui-1.10.4.custom.css" type="text/css">     <script src="js/jquery-1.10.2.js"></script>     <script src="js/jquery-ui-1.10.4.custom.js"></script>     <script src="js/scripts.js"></script>  </head> <body>     <label for="from">from</label>     <input type="text" id="from" name="from">     <label for="to">to</label>     <input type="text" id="to" name="to">     <p></p>      <input type="text" id="forminp1" size="30">&nbsp;<input type="text" id="forminp2" size="30"> </body> </html>

how can keep jquery code external have run when page loads?

wrap whole file in jquery document.ready function this.

jquery document ready

the basics need run on page load needs inside

$( document ).ready(function(){ ... });

or shortcut

$( function(){ ... });

see docs more info on this.

script on bottom of page

you put <script src="..."></script> on bottom of page, right above </body> tag.

this considered best practice way of doing things.

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
