Detect the error message in the input field

由 和自甴很熟 提交于 2020-07-20 18:03:11
问题 How can I show the message if the user types a restricted symbol? For example, if the user types * in the input field, the error message can show A filename cannot contain any of the following characters: \/:*?"<>| . I hope someone can guide me how to do it. Thanks. <!DOCTYPE html> <html> <body> <h1>How to show error message</h1> <input type="text" class="form-control blank" id="function_code" name="function_code" title="function_code" onpaste="return false"> </body> </html> <script> document

Log stdout + stderr and stderr simultaneously in R

由 一个人想着一个人 提交于 2020-04-16 05:49:39
问题 I want to have all stdout + stderr in one log file and simultaneously just stderr in another. How can I achieve this in R? Messages must keep the chronological order of all messages in both logs, for example say I have this code: options(warn = 1) cat("1st stdout\n") warning("2nd stderr") cat("3rd stdout\n") warning("4th stderr") How to make it redirect to both logs in the desired way? My thought that it could be simple if it was possible to merge and split the R connections, see the question

Semantic HTML for confirmation, error and warnings messages

由 ﹥＞﹥吖頭↗ 提交于 2019-12-09 10:39:30
问题 What are people's opinions on semantic HTML for confirmation, error and warnings messages? Currently I have something simple like: <div class="message message-warning"> <h3>Message Title</h3> <p>Message text</p> </div> Whereby the message-warning class gets replaced by message-confirmation or message-error if the message is a different type. Is there a more semantic way of marking this up? 回答1: May I suggest <figure> ? Excerpt from HTML5 Doctor (and they, from W3C): The figure element

Google App Maker - Add a button for timestamp collection in the onclick method

由 ￣綄美尐妖づ 提交于 2019-12-02 15:53:46
问题 I searched high and low and cannot find a specific answer that works. I need to add a button to a form in App Maker to record a timestamp, not a date, when clicked. So far the only thing that I've managed to get to work is widget.datasource.item.Timestamp_OUT = new Date(); I've also tried var timestamp = getTimeStamp(); But keep getting an error "ReferenceError: "getTimeStamp" is not defined". I'm probably missing the obvious as it shouldn't be this difficult to do something this simple. Any

Turning off “Language Service Disabled” error message in VS2017

由 天大地大妈咪最大 提交于 2019-11-30 02:44:43
We are getting the following "Error" message in our MVC web application in Visual studio 2017 Enterprise. The language service is disabled for project 'C:\Work\Blackhawk Platform\Platform-DEV-Branch\BlackhawkViewer\BlackhawkViewer.csproj' because it included a large number of .js files. Consider excluding files using the 'exclude' section of a 'tsconfig.json' file. I have tried turning off the Language service in the options but this does not turn the message off: This is a rather large web application. Is there a way to turn this message off without disabling any files in the tsconfig.json
