html - Why don't the modern browsers support PUT and DELETE form methods? -

-

i finished building restful api 1 of latest apps. built simple admin interface scaffolding class enumerate resources , build simple forms , tables edit, create, delete etc.

for updating , deleting resources, class outputs form methods of put , delete, pretty simple:

<form action="/posts/xxxxxxx" method="delete"> <input type="submit" value="delete" /> </form>

and

<form action="/posts/xxxxxxx" method="put"> <input type="text" name="username" value="nikcub" /> <input type="text" name="fullname" value="nik cubrilovic" /> <input type="text" name="email" value="nikcub@email.com" /> <input type="submit" value="update" /> </form>

very simple. if javascript detected, intercept form , use xmlhttprequest submit back. javascript supports other http methods, why don't modern browsers support put , delete methods? ends sending get.

i prefer when app gracefully falls standard html same methods used, instead of having use hidden fields , logic in class, or worse, putting method in uri , allowing work.

i can't think of reasons why browsers wouldn't support other http methods, since developers working around anyway hacking or using post.

i searched answer, , able find specified part of the xhtml 2.0 spec. there no mention of in html5 spec.

any reason not being supported in 'html5 compliant' browsers? can post request open , implemented in browsers?

some web frameworks (e.g. ruby on rails) around including hidden _method parameter in form value of "actual" method, e.g.:

<form action="/posts/xxxxx" method="post">     <input type="hidden" name="_method" value="delete">     <input type="submit" value="delete"> </form>

the framework rewrites request on server side before processing use value of _method parameter http method.

don't know if helps you.

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...
