javascript - Change the first value of a title -

-

i need change first value of title. did don't know if it's best way it.

html: 

<div title="title have change"> div here </div>

js:

$("div").click(function(){      var title =  $(this).attr('title').split(' ')[0];         /*            title getting first value (title), so,             need change him.        */         // better way ?        if(title == "title"){              $(this).attr("title", "changed have change");        } });

can change part of title, instead that?

keep of parts of title around. change first part, join parts form new title.

$("div").click(function(){      var parts =  $(this).attr('title').split(' ');         /*            change part[0]        */         // put parts        $(this).attr("title", parts.join(" " )); });

alternatively, if transformation relatively simple (say remove first word if it's title), use regular expression.

$("div").click(function(){      var newtitle =  $(this).attr('title').replace(/^title /,''); // space important      $(this).attr("title", newtitle); });

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.

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...
