Question

我有一个asp texbox，它有占位符和jquery自动完成功能。两者在chrome方面都运行良好但在IE8占位符不起作用。为了使其工作，我在jquery中为占位符添加水印，但随后显示水印，但自动完成功能无效。所有问题都在IE8中：

<asp:TextBox ID="txtLocation" runat="server" CssClass="frmhometxtLocation" placeholder="Locations"
                            onblur="Javascript:FormatLocation();"></asp:TextBox>


        $("#txtLocation")
        // don't navigate away from the field on tab when selecting an item
          .bind("keydown", function (event) {
              if (event.keyCode === $.ui.keyCode.TAB &&
                $(this).autocomplete("instance").menu.active) {
                  event.preventDefault();
              }
          })

          .autocomplete({
              delay: 0,
              minLength: 1,
              source: function (request, response) {
                  // delegate back to autocomplete, but extract the last term
                  response($.ui.autocomplete.filter(
                locations, extractLast(request.term)));
              },
              focus: function () {
                  // prevent value inserted on focus
                  return false;
              },
              select: function (event, ui) {
                  var terms = split(this.value);
                  // remove the current input
                  terms.pop();
                  // add the selected item
                  terms.push(ui.item.value);
                  // add placeholder to get the comma-and-space at the end
                  terms.push("");
                  this.value = terms.join(", ");
                  return false;
              }
          });
    });

我在这里犯了一个错误，但不包括Watermark.min.js。使用工具提示进行水印。现在它工作得很好。这是正确的代码：

public void executeMultipartPost() throws Exception {
    try {

        MultipartEntityBuilder builder = MultipartEntityBuilder.create();
        builder.setCharset(Charset.forName("UTF-8"));
        builder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);  
        Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher);
        ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
        bitmap.compress(Bitmap.CompressFormat.PNG, 100, byteArrayOutputStream);
        byteArray = byteArrayOutputStream.toByteArray();


        builder.addTextBody("file1", byteArray.toString());
        builder.addTextBody("file2", byteArray2.toString());

        // send
        InputStream inputStream = null;
        HttpClient httpClient = AndroidHttpClient.newInstance("Android");
        HttpPost httpPost = new HttpPost(UPLOAD_URL);
        httpPost.setEntity(builder.build());
        HttpResponse httpResponse = httpClient.execute(httpPost);
        HttpEntity httpEntity = httpResponse.getEntity();
        inputStream = httpEntity.getContent();

        // response
        BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream, "UTF-8"));
        StringBuilder stringBuilder = new StringBuilder();
        String line = null;
        while ((line = bufferedReader.readLine()) != null) {
            stringBuilder.append(line + "\n");
        }
        inputStream.close();

        // result
        String result = stringBuilder.toString();

    } catch (Exception e) {
        e.printStackTrace();
    }
}

asp文本框占位符和自动完成功能在IE8中不能一起使用
