Question

我正在尝试计算在textarea字段中输入的单词数。如果字数少于500个字，我想显示“您的文字少于500个字”，如果字数超过500个字，它应该显示“很好！您的文字超过500个字”。我该如何实现？

$(document).ready(function()
{
    var wordCounts = {};
    $("#my_word_count").keyup(function() {
        var matches = this.value.match(/\b/g);
        wordCounts[this.id] = matches ? matches.length / 2 : 0;
        var finalCount = 0;
        $.each(wordCounts, function(k, v) {
            finalCount += v;
        });
        $('#display_word_count').html(finalCount);
        am_cal(finalCount);
    }).keyup();
 });

<textarea name="txtScript" id="my_word_count" cols="100" rows="10"></textarea>
<br>Total word Count : <span id="display_word_count">0</span> words.

Code Snippet

我不建议计算单词边界，而是建议计算实际单词。

$(document).ready(function() {
  var $wordCountDisplay = $('#display_word_count');
  var $wordCountDisplayMessage = $('#display_word_count_message');
  var desiredMinimumWordCount = 10;
  
  $('#my_word_count').on('input', function (e) {
    var wordCount = ( e.target.value.match(/\w+/g) || [] ).length;
    $wordCountDisplay.text(wordCount);
    
    if (wordCount < desiredMinimumWordCount) {
      $wordCountDisplayMessage.text('Your text is below '+ desiredMinimumWordCount +' words please write some more');
      $wordCountDisplayMessage.removeClass('greatJob');
    } else {
      $wordCountDisplayMessage.text('Great job! Your text is over '+ desiredMinimumWordCount +' words');
      $wordCountDisplayMessage.addClass('greatJob');
    }
  }).trigger('input');
});

.greatJob { color: blue; }
