javascript - Can I prevent history.popstate from triggering on initial page-load? -

-

i'm working on site serves content via ajax.

if click item in menu, content div gets updated $.get response, nothing fancy.

i'm implementing history.pushstate allow navigation browser's back/forward button.

i have following load content on history navigation:

$(function() {     $(window).bind("popstate", function() {         $.getscript(location.href);      }); });

the problem is, when page loaded first time, function $.getscript page loaded again. first time page loaded renders initial html view, on second load renders js view, since js request.

how prevent event firing on pages html requests?

using native html5 history api you're going run problems, every html5 browser handles api little bit differently can't code once , expect work without implementing workarounds. history.js provides cross-browser api html5 history api , optional hashchange fallback html4 browsers if want go down route.

for upgrading website ria/ajax-application can use code snippet: https://github.com/browserstate/ajaxify

which part of longer article intelligent state handling goes explanations hashbang, hashes , html5 history api.

let me know if need further :) cheers.

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...
