textarea

问题 I am dealing with a text area in part of a contact form that Chrome wants to autofill with the user's address. As a result many contact requests are submitted by users with their address in the comment field. Besides the obvious potential security issues that could be exploited, my concern is that from a user's standpoint we're providing a contact form without an area to type a message. And from a support standpoint, we're having to ask users to send us another message with their actual

问题 I'm implementing a simple ( not rich ) text editor in html using a fixed size ( doesn't automatically grow ) textarea. I have made a pagination system which splits the text to fit that textarea. With relativelay large texts ( 20 pages = 20 textareas ) the function takes about 100ms in total for those 20 pages ( less if there is less text ). the logic is like this: function paginate() { clienth = textarea.clientheight; while (maxTextSize>minTextSize+1) { textarea.value = text; // a binary

问题 I think this is a simple and a silly question. I have included a text area in my html script. Is it possible to change the default font of the text area? The default one doesn't look good. I hope there is a way to change it. 回答1: Yes, using the CSS font-family property, just like any other element. The W3C has a CSS tutorial as does Mozilla 回答2: You can just open your css file and write code as mentioned below textarea { font-family:"Times New Roman", Times, serif; font-size: 12px; } By

问题 I try to get value into a input text and add it to a text area with react-bootstrap. I know I must use ReactDOM.findDOMNode to get value with ref. I don't understand what is wrong. Here my code : import React from 'react'; import logo from './logo.svg'; import ReactDOM from 'react-dom'; import { InputGroup, FormGroup, FormControl, Button} from 'react-bootstrap'; import './App.css'; class InputMessages extends React.Component { constructor(props) { super(props); this.handleChange = this

问题 We are trying to count the number of rows in a TextArea Here are the TextArea properties PrefWidth 600 and PrefHeight 620 with MaxHeight 620 Wrap Text is set to true. We are using JavaFX 8 with Scene Builder We have a textPropertyListiner that will fire an Alert when the TextArea.getLength is greater than some value The issue with this method is it does not consider the user entering a carriage return \n So we implemented this code to capture the \n String toCount = txaDiaryEntry.getText();

问题 Given a textarea with content that flows like this –––––––––––––––––––––––––– | This is some text, which | | wraps like this. | –––––––––––––––––––––––––– How can one tell if the text-cursor is on the first line of the textarea? Obviously, checking for a newline character ( \n ) works if one wants to see if the cursor appears before the first line break, but testing for a 'soft' line break seems more challenging. Here is a sample jsFiddle to experiment with. I have not yet come up with a

问题 I have a little issue related to when I place a text loaded via ajax call. I take the contect from a textarea and store it in my database and when I want to show the text in a div, it doesn't respect the new lines, so all the text is continuous. The following code show a small example: $(function() { $('.buttonA').click(function() { $('.message').html($('textarea[name="mensaje"]').val()); }); }); .message { width:300px; height:200px; } <script src="https://ajax.googleapis.com/ajax/libs/jquery

问题 This question has been answered, but for future reference here is a full example. You can click the add button and clear button as many times as you want and it will work.
