javascript - Help with Prototype JS and event binding -

-

i working on website has form , includes js file: http://assets.sprint.degreesearch.org/assets/defaults.js?1311179143

what trying dynamically apend function on form submit (either via onclick function on submit button or via overwriting functions included in js gets triggered on form submit.

the problem not familier prototype.js , unable execute function on form submit. when on onclick, triggers gets canceled prototype believe , execution stopped mid way.

the website in question step4 of http://sprint.degreesearch.org/collegefunnel website, on step4, while pressing submit, want run js function ideally takes around 200-300ms

any pointers how can unbind event associated mouse press , insert dynamic script ahead of , bind whatever has been binded default

thanks sparsh gupta

prototype has stopobserving method unbinding events. depending on events being bound, call stopobserving on form submit or other elements' mouse events.

however, don't think that's problem here. when want run js function takes 200-300ms, confused. javascript synchronous, time takes execute irrelevant. suspect there's unstated requirement function in question asynchronous call may not return period of time.

in case, want cancel form submission. form submission happening in 1 of 2 ways: either it's natural form submission, or in effect triggering asynchronous call of kind.

if it's natural form submission, can bind new event handler form's submit action , call event.preventdefault() stop browser posting server. later, call .submit() on form kick off again.

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...
