<div class="text">Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.

你好， 我有兩個問題，第一，如果文本比右下角顯示文字格大小「顯示更多」旁邊點擊放大怎麼做在此並顯示彈出窗口中的所有文字？

Answer 1

您可以使用JS來計算文本中有多少個字符，如果超過div的數量，則顯示「顯示更多」按鈕。然後，您可以使用window.open打開一個彈出窗口。請參閱this fiddle

Answer 2

我會在頁面呈現後但在檢查高度之前設置高度，以查看它是否大於您所需的寬度。

jsfiddle.net/

var actualHeight, actualWidth; 
 
$(function(){ 
 
\t var $d = $('.text'); 
 
\t actualHeight = $d.height(); 
 
    if(actualHeight > 200){ 
 
    \t $('.seeMore').css('display','inline-block'); 
 
    } 
 
    $d.css('height','200px'); 
 
}); 
 

 
$('.SeeMore').click(function() { 
 
    $('.PopUp').fadeIn(10).html($('.text').text()) 
 
    });

.text 
 
{ 
 
    width:200px; 
 
    border:1px solid #000; 
 
    background-color:rgba(230,230,230,1); 
 
    overflow:hidden; 
 
    position:relative; 
 
    } 
 
    
 
    
 
.SeeMore 
 
{ 
 
    position:absolute; 
 
    bottom:0; 
 
    right:0; 
 
    background-color:rgba(230,230,230,1); 
 
    padding:0px 5px; 
 
    color:#008CFF; 
 
    width:100%;
