javascript - How to Go To Next HTML element using Java Script -

-

suppose have basic html page 5 text box , 1 button @ end.

now want go next html element , let's next textbox (same tab does), on press of key code 412 , on press of key code 417 , should able go previous element( same shift + tab ).

now can not use tab or can tab key absent on key board. help.

well code detect key press below:

document.onkeyup = keycheck;        function keycheck()  {     var keyid = event.keycode;    document.form1.keyname.value = event.keycode;    switch(keyid)     {        case 412:        document.form1.keyname.value = "rewind prseesd";        break;         case 417:        document.form1.keyname.value = "forward pressed";        break;       .................... }

now want next , prev on key code 412 , 417

first, build array elements in desired order:

var _arrelements = [ "myinput1", "myinput2", "myinput3" ];

second, change code detect textbox key pressed, find id in array , focus proper textbox before or after it:

function keycheck(evt) {     if (typeof evt == "undefined" || !evt)         evt = window.event; //ie...      var keyid = evt.which || evt.keycode;     var flag = 0;     switch(keyid) {         case 34:             flag = -1; //backward             break;           case 33:              flag = 1; //forward              break;     }     if (flag == 0)         return; //key not relevant      var sender = evt.target || evt.srcelement;     if (!sender)         return; //key did not come valid element      var nindex = -1;     (var = 0; < _arrelements.length; i++) {         if (sender.id == _arrelements[i]) {             nindex = i;             break;         }     }     if (nindex < 0)         return; //key did not come valid textbox      var newindex = nindex + flag;     if (newindex >= _arrelements.length)         newindex = 0;     if (newindex < 0)         newindex = _arrelements.length - 1;     document.getelementbyid(_arrelements[newindex]).focus(); }

live test case complete code available here: http://jsfiddle.net/yahavbr/vah8r/

in example i'm using page up/page down, no idea keys produce codes gave.

edit: can put id of every focusable element want in array, doesn't have textbox.

razor - Is this a bug in WebMatrix PageData? -

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...

android - layout with fragment and framelayout replaced by another fragment and framelayout -

edit: so after comments below, revisted , realized hanging me up. imagine client list , client details activity started : public class clientsmainactivity extends fragmentactivity { @override public void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); //studiotabopenhelper db; setcontentview(r.layout.main_client_activity); } } so works great, starts main_client_activity (defined in layout below, , call activity when button on main screen clicked): intent intent = new intent(getactivity(), clientsmainactivity.class); startactivity(intent); easy issue is, clientsmainactivity not call oncreateview or anything, sets layout layout defines fragment, , listfragment. fine cause not trying pass clientsmainactivity , if have hypothetical activity like: sessionmainsactivity called when click on session edit of client, not calling sessionsmainactivity same way (starts activity sets alayout), want layout set defines...
