textarea

问题 I'm new to jQuery, so I bet I'm doing something wrong, but I cannot figure out why this event is not firing. I have a textarea element that needs to have any breaking spaces removed prior to submission due to the application that is accepting the data. I am attempting to do this clean up in the textarea when it loses focus, hence the blur method. Unfortunately it does not appear to fire within my form. The weird part is the same code works in jsFiddle, but only upon the initial loss of focus.

问题 I've got a problem with textarea's in Google Chrome. I'm using classic ASP, but this is unimportant as Chrome is actually posting the data incorrectly. The problem is with a text area. As soon as a string of text is too long to fit one line of the text area, it wraps to the next line (as it should). My problem is that when submitted, the form data contains a CarriageReturn & LineFeed at every spot where the text wrapped, as well as user generated enter/return events - I can't even tell the

问题 I'm trying to add a "change log" to my jQuery mobile Application. In case of an error, the user should have the capability, to see what went wrong.

问题 In my application, I'm using two Tabs. In the first I placed HtmlEditor and in the second one I placed TextArea. HTML tab is default and when user is creating HTML input, he can switch into TextArea to see / change the HTML source code directly. I've added a listener to get rhe htmlText from the HtmlEditor and set it as text in TextArea, so user can easily switch between HTML and source mode. Here's my listener: @FXML private Tab htmlTab; @FXML private Tab sourceTab; @FXML private HTMLEditor

问题 I have assembled a basic jfiddle below. For some reason my selector works to retrieve the textarea box to set the value, but the selector doesnt work to use the setSelectionRange function. On the console you'll find an error for .setSelectionRange is not a function. http://jsfiddle.net/dMdHQ/6/ code(please refer to jfiddle): selector.setSelectionRange(carat,carat); 回答1: setSelectionRange(carat,carat) is not a method on jquery object. You want to use it on DOM element. So try: selector[0]

The code below is the HTML/PHP code for the

问题 In my attempt to build a simple cross browser expanding text area I found that all plugins seam far too overly cluttered. I developed this: $(document).ready(function() { $('textarea').keyup(function() { var txtheight = this.scrollHeight; $(this).height(txtheight) }); $('textarea').keyup(); });​ It is producing unexpected results. On FIREFOX it is working but if I delete lines from the textarea it does not reduce in size. On CHROME the presseing of any key leads to another line height being

问题 I am having issues getting setCursor() to work properly in TextArea. I am not seeing any other search results at all for issues with this, and might be doing something silly because no one else has addressed this yet. I have tried different options, with no luck. Here are a few attempts below: Coding this below makes it so only the outer edges are effected by the setCursor. textArea.setCursor(Cursor.DEFAULT); In FXML, I get the following if I add it in with Scene Builder. <TextArea fx:id=
