由 China☆狼群 提交于 2019-12-12 07:03:20
问题 I need to be able to parse the attributes from an MvcHtmlString (the results of an HtmlHelper extension), so that I can update and add to them. For example, take this HTML element: <input type="text" id="Name" name="Name" data-val-required="First name is required.|Please provide a first name."> I need to take the value from data-val-required , split it into two attributes with the second value going into a new attribute: <input type="text" id="Name" name="Name" data-val-required="First name

问题 I'm working on reading a value from textBox (let it be Sam): <%= Html.TextBox("Name")%> and then on click of action link: <%: Html.ActionLink("Edit","Edit",routeValues %> I need to route (this URL should open) /Edit/Sam How can I do that? 回答1: Since you aren't using any route values above and instead just the name of the textbox you can just create a link Name your textbox "name" (if it isn't already) via the html attributes new {id="name"} (for ex) then you can just jQuery to get the value

Inline helpers and page output - how?

由 流过昼夜 提交于 2019-12-11 14:02:29
