Question

我会创建字段textarea，当用户输入html basic到textarea时，结果可以读取html。

代码基本

<form action="">
    Name:
    <input type="text">
    Contents:
    <textarea name="contents"></textarea>
</form>

在提交结果 Hello World 时，我将<strong>Hello World</strong>输入textarea
这就像Wordpress中的Widget Text。

您希望根据用户输入动态创建html元素。尝试使用JQuery！以下是一个示例：http://jsfiddle.net/ddan/m7jba0uk/1/

HTML：

 Thread streamThread = new Thread(new Runnable() {

                @Override
                public void run() {

                try {


                        int minBufSize = AudioRecord.getMinBufferSize(sampleRate, channelConfig, audioFormat)*10;


                       log2("Socket Created");

                  DatagramPacket packet;

                  final InetAddress destination = InetAddress.getByName("192.168.49.1");



                       recorder = new AudioRecord(MediaRecorder.AudioSource.MIC,sampleRate,AudioFormat.CHANNEL_CONFIGURATION_MONO,AudioFormat.ENCODING_PCM_16BIT,minBufSize);
                       log2("Recorder initialized");



                       byte[] buffer = new byte[1600];


                       recorder.startRecording();

                       int bytes_read = 0;
                       DatagramSocket socket1 = new DatagramSocket();

                        while(true) {


                            //reading data from MIC into buffer
                            bytes_read = recorder.read(buffer, 0, 1600);
                            //putting buffer in the packet
                            packet = new DatagramPacket (buffer, bytes_read,destination,9000);


                            socket1.send(packet);

                        }


                    } catch (IOException e) {
                        //Log.e("VS", "IOException");
                    } 


               }

            });
            streamThread.start();

JS：

<form action="">
    Name:
    <input type="text"><br>
    Contents:
    <textarea name="contents"></textarea>
</form>
<input type='button' onclick='doTheThing()' value='Do the thing'>
<div id='result'></div>

尝试输入function doTheThing() { $('#result').append($('textarea[name="contents"]').val()); }

我希望它有助于实现你的想法。
