我的应用程序中有评论部分，我使用此代码来获取评论，但我无法评论从键盘输入'enter'键，如何为enter键提供访问权限

Answer 1

您必须将FileInputStream input = new FileInputStream(new File("uinsoaptest.properties")); props.load(new InputStreamReader(input, Charset.forName("UTF-8")));个事件绑定到keypress / input

textarea

Answer 2

试试这个。

＆＃13;

<script type="text/javascript">
  $(document).ready(function() {
    $('.submit_on_enter').keydown(function(event) {
        if (event.keyCode == 13) {
            this.form.submit();
            return false;
         }
    });
  });
</script>

＆＃13;

<form action="path_to_the_action">
  <input class="submit_on_enter" onclick="return commentsByUser(this)">
</form>

＆＃13;

Answer 3

$(document).keypress(function (e) {
    if (e.which == 13) {
        alert('Enter key pressed');
        $('#sendButtonId').trigger('click');
    }
});

$('#sendButtonId').click(function(e) {
   // call ur function here...
});
