textarea

问题 I'm creating a suggestion panel while live editing an HTML textarea. To get the {x,y} coordinates I use an hidden div placed behind the textarea. I get the carret position and then copy the text before the carret plus a span tag to the hidden div. Then I get the span coordinates and give it to the suggestion panel. The only problem is that when I add a long line without spaces to the textarea, the line is being wrapped while it's cut in the div panel (so the suggestion panel is not well

问题 I am having trouble with TinyMCE. When it is searching for the lang, theme, and plugins, it is supposed to look in the directory where the base script files are located. however, instead of doing that, it is using the current loaded page as the root for searching. I am looking at the "loadScripts" function in the src file, but changing the path doesn't seem to provide any meaningful effect.

问题 This is very likely a bug, but I'm reporting it here for reference and for the slight chance of someone being able to propose a workaround.

问题 Is It possible to save a textarea to a file? FileWriter fw = new FileWriter(file1.getAbsoluteFile(), true); BufferedWriter bw = new BufferedWriter(fw); bw.write(txtArea1); I get: txtArea1 cannot be resolved to a variable.

Thus, your example might look something like: FileWriter fw = new FileWriter(file1.getAbsoluteFile(),

问题 Main Target : To create a website that will have a live preview of an HTML/CSS code. More specifically : The HTML/CSS code will be editable form the user in some specific parts. So, the code in the live preview will not derive from text areas but from divs. Image of what I am trying to do : So, in my Previous Question I tried to find a way to make the live preview box work after getting the code from the black boxes.

问题 I want my TextArea to be able to support multiple CodeMirror modes. For now I want it to support json and xml. Is this possible? Also, is it possible to automatically detect whether the user placed json or xml in the area? Thanks. 回答1: CodeMirror actually has an example very close to what you are looking for here. Here is a more specific example that does what you want. Create a CodeMirror instance. When the content changes we determine if we should switch modes. The logic I put in for
