some questions in load jquery.ajax -

- 

function  contentdisp() {     $.ajax({     url : "a2.php",     success : function (data) {     $("#contentarea").html(data);     }     }); }  <input type="button" value="click" onclick="contentdisp();">&nbsp;<span style="color:blue;"> <textarea id="contentarea" rows="10" cols="50"></textarea>

i'm new learning jquery.ajax now. found tutorial on web. these code control jquery.ajax when click button, load content a2.php div#contentarea. have questions:

  1. whether js code can add jquery(document).ready(function() if want open page, load html(data) @ onece, not click callback?

  2. whether jquery.ajax can load div's content form a2.php, not whole page? similar jquery.load $("#contentarea").load("a2.php #content"); .

thanks.

if put ajax call in document ready run , load content immediately. how default tab on jquery tabs works.

jquery.load abstraction full ajax function. can .ajax can .load

as note, don't calling $.ajax() of it's parameters repeatedly, i've shown pattern here: showing loading image in modal popup extender in webservice ajax call

for purpose, however, following snipped load page on page load.

<script>   $(document).ready(function() {      $.ajax({       url: "a2.php"       ,success: function(data) {         $("#contentarea").html(data);       }     });    }); </script>  <textarea id="contentarea" rows="10" cols="50"></textarea>

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...

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.
