javascript - is there a way to write the actual DOM to a string -

-

i have html document

<html> <head></head> <body> <form> <input type="text" value="" /> </form> <input type="button" id="doit" value="do it"/>     <!-- jquery --> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js">         </script>                     <script type="text/javascript">         $(document).ready(function() {             $("#doit").click(function(){             var dom = document.documentelement.innerhtml;             alert(dom);             });         });         </script> </body> </html>

if edit text field value still original blank value in alert...why? , how see actual dom in string?

you'd need set each attribute explicitly current value: http://jsfiddle.net/gw8eu/.

$("#doit").click(function(){     $('*').each(function() {         var $this = $(this);         for(var = 0; < this.attributes.length; i++) {             try {                 var t = this.attributes[i];                 $this.attr(t.name, $this.prop(t.name));             } catch(e) {}         };     });     var dom = document.documentelement.innerhtml;     alert(dom); });

it's rather dirty , not see real rationale behind outputting dom string, seems answer question.

one of reasons it's dirty try block essential, because otherwise you'd setting type attribute of input immutable. i'm pretty won't work other special attributes either, value of input works fine.

therefore still know what's reason behind wanting dom string; there more elegant solution.

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.

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...

i need sort through array , sort each individual row in array in ascending order. doesn't seem going (surprise!) keep getting hit 2 errors: a2101: cannot add 2 relocatable labels , a2026: constant expected here's sort, makes sense me, think i'm still trying implement high-lvl language techniqes assembly. there way around not being able use relative values?
