如果不满足最大长度，如何重新启用屏幕键盘

问题描述 投票：0回答：1

我有一个ul li键盘，首先获得4个数字，接下来是3个字母，然后禁用自己。但是，如果用户单击删除按钮，则不会重新启用它。

我想“如果我只是添加.removeClass（'禁用'），如果长度小于8，它可能会工作。但我很确定这不是这样的。请帮助我。

$(function() {
  var $write = $('#write'),
    symbols = $('.symbol'),
    letters = $('.letter'),
    shift = false,
    capslock = false;

  $('#keyboard li').click(function() {
    var $this = $(this),
      character = $this.html(); // If it's a lowercase letter, nothing happens to this variable

    // Shift keys
    if ($this.hasClass('left-shift') || $this.hasClass('right-shift')) {
      $('.letter').toggleClass('uppercase');
      $('.symbol span').toggle();

      shift = (shift === true) ? false : true;
      capslock = false;
      return false;
    }

    // Caps lock
    if ($this.hasClass('capslock')) {
      $('.letter').toggleClass('uppercase');
      capslock = true;
      return false;
    }

    // Delete
    if ($this.hasClass('delete')) {
      var html = $write.html();
      $write.html(html.substr(0, html.length - 1));
      return false;
    }

    // Special characters
    if ($this.hasClass('symbol')) character = $('span:visible', $this).html();
    if ($this.hasClass('space')) character = ' ';
    if ($this.hasClass('tab')) character = "\t";
    if ($this.hasClass('return')) character = "\n";

    // Uppercase letter
    if ($this.hasClass('uppercase')) character = character.toUpperCase();

    // Remove shift once a key is clicked.
    if (shift === true) {
      $('.symbol span').toggle();
      if (capslock === false) $('.letter').toggleClass('uppercase');

      shift = false;
    }


    $write.html($write.html() + character);
    text1 = document.getElementById('write').value;
    console.log(text1);
    if (text1.length >= 4) {
      symbols.addClass('disabled');
      letters.removeClass('disabled');
      if (text1.length == 7) {
        letters.addClass('disabled');


      }

    }
    if (text1.length > 7) {
      letters.removeClass('disabled');
    }





    // Add the character

除了它缺少重要的功能之外，还有它需要做的事情。没有经验足以解决这个问题。 （ps这个键盘字面上并不关心textarea字符限制，因为它不是onkeypress，我不知道它是什么。所以我只是进行一些即兴创作来解决。如果你只是用键盘写它，它会去键入最多4个字母，因为这是文本区域的限制。如果你用屏幕键盘写它，你会得到7.帮助？）

（P.S.S：为什么“LEFT-TAB”在最小化的时候会继续上升？）

我想“如果我只是添加.removeClass（'禁用'），如果长度小于8，它可能会工作。但我很确定这不是这样的。

这不起作用，因为当您处理删除按钮时，您使用了“return false;”，这意味着它将在那里返回，而不是继续将代码运行到.removeClass('disabled')部分。

我的解决方案是您需要在删除功能中处理添加和删除功能，如下所示：

// Delete
if ($this.hasClass('delete')) {
    var html = $write.html();
    $write.html(html.substr(0, html.length - 1));

    //get text1 value from textarea
    text1 = document.getElementById('write').value;

    //When length < 4, just enable numbers, disable letters
    if (text1.length < 4)
    {
        symbols.removeClass('disabled');
        letters.addClass('disabled'); 
    }

    //When length >= 4, handle like your current code
    if (text1.length >= 4)
    {
        symbols.addClass('disabled');
        letters.removeClass('disabled'); 
         if(text1.length == 7){
            letters.addClass('disabled');

        }
    }

    return false;
}

因此，在删除部分中，您将处理虚拟键盘上的禁用。

从那以后，您可以在代码中删除此部分：

if (text1.length > 7) { letters.removeClass('disabled'); }

对于物理键盘输入，如果您不希望用户使用它，您可以在textarea部分设置maxLength="0"。

<textarea type="text" required id="write" maxLength="0" placeholder="UBA0000"></textarea>

请查看下面的演示以了解它是如何工作的。

编码时间快：D。
