问题 I apologize to move it from here as there was some confusion and thanks to Grey for answer this to realized the mistake. The topic has been moved to Javascript: Behavior of {} to discuss further. Singleton Pattern with '{}'. Here how it is: var A = { B : 0 }; // A is an object? document.write("A is an " + typeof A); Lets try to clone object A var objectOfA = new Object(A); objectOfA.B = 1; //Such operation is not allowed! //var objectOfA = new A(); var referenceOfA = A; referenceOfA.B = -1;

Why doesn't javascript “this” work with “each”?

由 假如想象 提交于 2019-12-11 12:24:06
问题 I'm trying to assign a class to an element upon detecting that it has a data-voted attribute of "true" , but the simple addClass line is not working. I was using $(this) until I read jQuery's documentation for each() , and then switched to the following: windowReady = -> jQuery -> $voteLinks = $('.vote-button a') $voteLinks.each (i, current) -> if $(current).data('voted') == "true" $(current).addClass('voted') $(window).load(windowReady); $(window).on('page:load', windowReady); $(this)

Prevent form from submitting when using unobtrusive validation in ASP.NET MVC 3

由 会有一股神秘感。 提交于 2019-12-11 04:48:56
问题 I am trying to implement remote validation using ASP.NET MVC3 unobtrusive javascript. It seems to work, but I am able to submit my form even if it is not supposed to be valid. It looks like the validation is not happening fast enough. I am using the ASP.NET development server with the VS 2010 debugger and the remote validation method is not always fired. When I wait a little, the validation happens and I cannot submit the form. I am starting to think that client-side remote validation is not

Hide html only when Javascript is available

由 て烟熏妆下的殇ゞ 提交于 2019-12-10 21:31:42
问题 I guess this is more about SEO than wanting to support browsers with Javascript disabled. I have Javascript/jQuery code that reads in some html and basically displays it much nicer. The html is actually removed (with jQuery's .remove() function) during the process. So I hide the html so there aren't any visual artifacts as the page loads. But now I want to only hide it if Javascript is enabled. I guess the easiest thing is to have some Javascript in <head> that adds the display: none css rule

Best way to signal my JS script is loaded

问题 I have a JS script that will be hosted on my server and that others will embed in their html, i.e. ...<code for http://yoursite.com /> <script type="text/javascript" src="http://mysite.com/awesome.js" /> ...<code for http://yoursite.com /> My script declares an object with a bunch of properties accessible for use as a javascript Object(), i.e. <script type="text/javascript"> //From http://mysite.com/awesome.js alert(Awesome.Name); </script> Due to the load time variance, it seems I need to

Ajax.BeginForm routing to new page instead of a partial view

由 你说的曾经没有我的故事 提交于 2019-12-10 13:13:58
问题 I have a Ajax.BeginForm call that is supposed to return a partial view but is rerouting the page to the Action instead. Any ideas on what is wrong? Here is the code on the main page that I want to render the partial view on: <div class="col-md-6"> @using (Ajax.BeginForm("Search", "Home", new AjaxOptions { HttpMethod = "GET", InsertionMode = InsertionMode.Replace, UpdateTargetId = "searchResults" })) { <div class="form-group" style="width:85%;"> <div class="right-inner-addon"> <i class="

jQuery Accordion definition list with multiple description items

由 送分小仙女□ 提交于 2019-12-10 05:31:50
问题 I can't seem to use jQuery Accordions with definition lists that have multiple desciption items (dd). The author's examples have only single dd items. In the example below B2, B3 & C2 show onLoad, rather than hide like A1, B1 & C1 as I would prefer. How would I achieve this? jQuery('dl').accordion({ event: 'click', active: false, animated: "bounceslide", header: "dt" });​ <dl> <dt>A</dt> <dd>A1</dd> <dt>B</dt> <dd>B1</dd> <dd>B2</dd> <dd>B3</dd> <dt>C</dt> <dd>C1</dd> <dd>C2</dd> </dl> (Live

问题 Using jQuery unobtrusive validation within a .NET MVC project and that seems to be working fine. I'm now trying to show a green checkmark when the field validates correctly (client-side and/or remote). Here's a sample field declaration: <div class="clearfix"> @Html.LabelFor(model => model.Address1, "Street") <div class="input"> @Html.TextBoxFor(model => model.Address1, new { @class = "xlarge", @maxlength = "100", @placeholder = "e.g. 123 Main St" }) <span class="help-message"> @Html
