javascript - object literal and Sys.WebForms.PageRequestManager.getInstance().add_endRequest issue -

-

what i've got asp.net masterpage/contentpage, contentpage utilizes updatepanel updatemode set "conditional". contentpage multiview has 3 views: setup, confirm, , complete. i've got navigation buttons when clicked, go server, need , update updatepanel can come back. problem lies in javascript.

i have following global object literal named page:

page = {      panel : undefined,     currentview: undefined,      buttons : {          : undefined,         cont : undefined      },      views : {          setup       : {},         confirm     : {},         complete    : {}      }  };


page.init() function looks this:

page.init = function() { console.log("page.init() fired");      this.panel    = $('div[id$="panel_page"]');     this.currentview  = this.panel.find('input[id$="hidden_currentview"]').val();     this.buttons.all  = this.panel.find('input[type="submit"]');     this.buttons.cont = this.panel.find('input[id$="button_continue"]');      this.buttons.all.click(function() { page.panel.hide(); });      switch (this.currentview) {          case "confirm"      : this.views.confirm.init();    break;         case "complete"     : this.views.complete.init();   break;         default             : this.views.setup.init();      break;      }  };


, last, not least, gets kicked off by: 

// fire events on initial page load. page.init();  // fire events partial postbacks. sys.webforms.pagerequestmanager.getinstance().add_endrequest(page.init);


issue when first fires page.init() great, however, when click button throws error of: uncaught typeerror: cannot set property 'all' of undefined. i've tried figure out, i'm @ loss. seems though happens any nested object literal off of root of page. immediate properties page.panel work fine, need access page.buttons.all or page.views.setup, throws error. have never seen before.

any ideas out there?

use getter panel property. seeing else appears property of panel should - might losing reference panel during postback, instead of getting object once, every time:

get_panel: function() { return $get("panel_page"); }

again, if have this.panel = $get(myelement) , partial page update destroys node returned this.panel when created object initially, this.panel become undefined. use getter.

hope helps - happy coding.

edit:

actually - @ again, you'll want use getters of properties instead of relying on get_panel().find(..) currentview, example, i'd getter there:

get_currentview: function() { return $get("hidden_currentview", this.get_panel()); }

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...
