Piece accessing attributes with camelCase names (e.g., information-productName) is easy, dashes necessitate utilizing bracket notation. Ideate you person the property information-merchandise-sanction. Trying to entree it by way of component.dataset.productName straight gained’t activity.
Alternatively, make the most of bracket notation: component.dataset['merchandise-sanction']. This ensures the JavaScript motor accurately interprets the property sanction, permitting entree to the related worth. Retrieve this discrimination once running with dashed attributes to debar surprising null oregon undefined values.
This method is important for dynamic net interactions. For illustration, you may easy fetch the merchandise sanction from the supra illustration utilizing: fto productName = papers.getElementById('merchandise-1').dataset['merchandise-sanction'];
Server-Broadside Entree successful ASP.Nett MVC
Accessing information- attributes from your C codification inside your ASP.Nett MVC controllers oregon Razor views requires a antithetic attack. You tin leverage the .Attributes place of the HtmlHelper entity. This permits you to retrieve the worth of immoderate property, together with these with dashes.

@Html.TextBox("ProductName", null, fresh { @people = "signifier-power", data_product_category = "Electronics" })
Successful your controller, you tin past entree this information-merchandise-class worth through the Petition entity:
drawstring productCategory = Petition.Signifier["ProductName"].Attributes["information-merchandise-class"];
Champion Practices and Issues
Piece dashes are permitted, utilizing camelCase (e.g., information-productCategory) for information- attributes frequently simplifies entree successful JavaScript, eliminating the demand for bracket notation. Keep consistency inside your task to better readability and trim possible errors.
Prioritize descriptive property names that intelligibly convey the saved information’s intent. This enhances codification maintainability and makes it simpler for others (oregon your early same) to realize the performance.
- Usage camelCase oregon dashes constantly.

Question & Answer :
I americium attempting to usage HTML5 information- attributes successful my ASP.Nett MVC 1 task. (I americium a C# and ASP.Nett MVC beginner.)
<%= Html.ActionLink("« Former", "Hunt", fresh { key phrase = Exemplary.Key phrase, leaf = Exemplary.currPage - 1}, fresh { @people = "prev", information-particulars = "Any Particulars" })%>
The “information-particulars” successful the supra htmlAttributes springiness the pursuing mistake:
CS0746: Invalid nameless kind associate declarator. Nameless kind members essential beryllium declared with a associate duty, elemental sanction oregon associate entree.
It plant once I usage data_details, however I conjecture it demand to beryllium beginning with “information-” arsenic per the spec.
My questions:
- Is location immoderate manner to acquire this running and usage HTML5 information attributes with Html.ActionLink oregon akin Html helpers ?

This job has been addressed successful ASP.Nett MVC three. They present robotically person underscores successful html property properties to dashes. They bought fortunate connected this 1, arsenic underscores are not ineligible successful html attributes, truthful MVC tin confidently connote that you’d similar a sprint once you usage an underscore.
For illustration:
@Html.TextBoxFor(vm => vm.Metropolis, fresh { data_bind = "foo" })
volition render this successful MVC three:
<enter information-hindrance="foo" id="Metropolis" sanction="Metropolis" kind="matter" worth="" />
If you’re inactive utilizing an older interpretation of MVC, you tin mimic what MVC three is doing by creating this static technique that I borrowed from MVC3’s origin codification:
national people Foo { national static RouteValueDictionary AnonymousObjectToHtmlAttributes(entity htmlAttributes) { RouteValueDictionary consequence = fresh RouteValueDictionary(); if (htmlAttributes != null) { foreach (Scheme.ComponentModel.PropertyDescriptor place successful Scheme.ComponentModel.TypeDescriptor.GetProperties(htmlAttributes)) { consequence.Adhd(place.Sanction.Regenerate('_', '-'), place.GetValue(htmlAttributes)); } } instrument consequence; } }
And past you tin usage it similar this:
<%: Html.TextBoxFor(vm => vm.Metropolis, Foo.AnonymousObjectToHtmlAttributes(fresh { data_bind = "foo" })) %>
and this volition render the accurate information-* property:
<enter information-hindrance="foo" id="Metropolis" sanction="Metropolis" kind="matter" worth="" />
