Question

到目前为止，我已经做了一些工作，并且可以在下面的示例中看到的b块上工作。

我想让它变得优雅，但我不知道怎么做。

所以我的问题是：如何使两个块（a和b）分别工作，但要根据div的宽度和高度执行相同的操作，以减小字体大小。

我也使用跨度将段落放在一行中（例如在我的示例中）

基于其中之一的缩小，字体在两个跨度中必须具有相同的大小。

;(function($) {
    $.fn.textfill = function(options) {
        var fontSize = options.maxFontPixels;
        var ourText = $('span', this);
        var maxHeight = $(this).height();
        var maxWidth = $(this).width();
        var textHeight;
        var textWidth;
        do {
            ourText.css('font-size', fontSize);
            textHeight = ourText.height();
            textWidth = ourText.width();
            fontSize = fontSize - 1;
        } while ((textHeight > maxHeight || textWidth > maxWidth) && fontSize > 3);
        return this;
    }

    $.fn.textfill2 = function(options) {
        var fontSize = options.maxFontPixels;
        var ourText1 = $($('span', this)[0]);
		console.log(ourText1);
		var ourText2 = $($('span', this)[1]);
		console.log(ourText2);
        var maxHeight = $(this).height();
        var maxWidth = $(this).width() + 5;
        var textHeight;
        var textWidth;
		var width1;
		var width2;
        do {
            ourText1.css('font-size', fontSize);
			ourText2.css('font-size', fontSize);
            textHeight = ourText1.height() + ourText2.height();
			width1 = ourText1.width();
			width2 = ourText2.width();
            textWidth = Math.max(width1, width2);
            fontSize = fontSize - 1;
        } while ((textHeight > maxHeight || textWidth > maxWidth) && fontSize > 3);
		
		// ourText1.css('font-size', 140);
        return this;
    }
})(jQuery);

$(document).ready(function() {
    $('#blocka').textfill({ maxFontPixels: 140 });
    $('#blockb').textfill2({ maxFontPixels: 140 });
});

我找到了解决此问题的方法：）

如果要这样做，则必须像这样使用它：

(function() {
  var elements = $('.resize');
  if(elements.length < 0) {
    return;
  }
  elements.each(function(i, element) {
    while(element.scrollWidth > element.offsetWidth || element.scrollHeight > element.offsetHeight) {
      var newFontSize = (parseFloat($(element).css('font-size').slice(0, -2)) * 0.95) + 'px';
      $(element).css('font-size', newFontSize);
    }
  });
})();

.no-resize, .resize {
  width: 100px;
  height: 50px;
  border: 1px solid #000;
  color: #000;
  margin: 20px 0;
  font-size: 15px
}
.nowrap {
  width: 250px;
  white-space: nowrap;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class='container'>
  <div class='no-resize'>This text won't be resized and will go out of the div.</div>
  <div class='resize'>This text will be resized and wont go out of the div.</div>
  <div class='no-resize nowrap'>This text won't be resized and will go out of the div.</div>
  <div class='resize nowrap'>This text will also be resized and wont go out of the div.</div>
</div>
