Question

这是我的代码

echo'

<td class="success"><button  id="btn-Preview-Image" class="btn btn-success" name="sure" onClick="PrintElem('.'mydiv'.$row['id'].''.');">print</button></td>

';

像这样打印的onclick方法

onClick="PrintElem(mydiv12);"

但是我想要这样一个引号

 onClick="PrintElem('mydiv12');"

Answer 1

尝试将双引号引起来

echo '<td class="success">
        <button  id="btn-Preview-Image" class="btn btn-success" name="sure" 
        onClick="PrintElem(' . "'mydiv".$row['id'] ."'" . ');">print</button>
        </td>';

这可以通过添加和转义单引号来实现：

public class BitmapWebView extends WebView{

    private void init(){
        stream = new ByteArrayOutputStream();
        array = new ReadData(new byte[]{});
        bm = Bitmap.createBitmap(outputWindowWidth,
             outputWindowHeight, Bitmap.Config.ARGB_8888);
        bmCanvas = new Canvas(bm);
   }


    @Override
    public void draw( Canvas ){
        // draw onto a new canvas  
        super.draw(bmCanvas);
        bm.compress(Bitmap.CompressFormat.PNG, 100, stream);

        array.Buffer = stream.toByteArray();
        UnityBitmapCallback.onFrameUpdate(array,
            bm.getWidth(),
            bm.getHeight(),
            canGoBack,
            canGoForward );
        stream.reset();

    }
}  
// you need this class to communicate properly with unity
public class ReadData {
    public byte[] Buffer;
    public ReadData(byte[] buffer) {
        Buffer=buffer;
    }
}

结果（来自HTML来源）：

RawImage
