问题 You've probably seen fancy search boxes before (like the one on the jQuery API) where they have a clickable search icon that appears over the textbox. How can I semantically achieve this effect? I have seen on some custom Google Search textboxes that it uses a background image on the textbox, and then it receives focus and removes the image. Also, the search box here on StackOverflow appears to also be using a background image of a little search icon. I know how to do that, it is easy, but it

问题 Here is what I want to create: A program where the user can enter any decimal number and is told all the qualities of that number. (For example: even/odd, divisible by 2/5/10, is a prime number, etc...) Sadly I'm already failing at grabbing the number from the user input. I need a TextBox that only allows Numbers. (I know NumericUpDown is an option but I wanted to try it with a TextBox) I need to convert the String from the TextBox into a float (?) (or double ?). I know int won't work because

问题 I have a single line of text in a Text Box and that is wrapped to many lines, how to count no of wrapped lines in Text Box? 回答1: You could use String.Split : int lineCount = txt.Text.Split(new[] { '\n', 'r' }, StringSplitOptions.None).Length; If it's a winforms TextBox you can also use the Lines property: int lineCount = txt.Lines.Length; So it's VB.NET: Dim lineCount = txt.Text.Split({vbLf, vbCr}, StringSplitOptions.None).Length Update : Maybe my understanding was wrong and you want to count

问题 On my page I have a Radio button list and a textbox. The textbox is hidden by default then appears if the user clicks yes. Once they click yes then the textbox must be filled in before they can proceed. I've put in the following code, however it doesn't seem to work at all and when the button is pressed to go to the next page it continues instead of stopping and asking the user to enter something in the box. function Q12iYes() { document.getElementById('txt12i').style.display = "block" }

问题 I have been trying to get the fields to work, but keep failing. I have also been trying to look for examples, but the only examples I could find are using Elm 0.14, which use the new Channel API which isn't available in Elm 0.13.

问题 I'm creating a system that reads/writes a spreadsheet using PhpSpreadsheet. Does this library support the use of textboxes? When I tried all the textboxes were deleted. 回答1: No, PhpSpreadsheet doesn't support any form elements; and features of Excel that aren't supported simply aren't loaded when the file is loaded, so don't exist in the spreadsheet object when it is saved 来源： https://stackoverflow.com/questions/54833862/writing-xlsx-file-with-phpspreadsheet-deletes-all-the-textboxes

问题 What I'm trying to do is get an asp:button to click. The only problem is that it is within a few tags. Example: <loginview> <asp:login1> <logintemplate> //asp:textbox and asp:button are located here. </loginview> </asp:login> </logintemplate> So how would I get javascript to point to that location so that I can manipulate it. For example, get the button to click. 回答1: First, you need to figure out which template is being used, since you can only access the active one. (Anonymous or LoggedIn).
