如何将jQuery省略号应用于div

Question

$('.more2').each(function() {       
    var showChar = 150;
    var content = $(this).html();
        if(content.length > showChar) {
            var c = content.substr(0, showChar);
            var h = content.substr(showChar, content.length - showChar);
            var html = c + '<span class="moreellipses">' + ellipsestext+ ' </span><span class="morecontent"><span>' + h + '</span>  <a href="" class="morelink">' + moretext + '</a></span>';
            $(this).html(html);
    }
});

我正在尝试为我的div下拉列表构建一些jquery手风琴效果； 请参阅示例JSFIDDLE 。 在这里，我实际上想要的是单击（'+'）按钮，然后显示部分内容。 当时，同一行中的其他div应该具有与活动div相同的高度，但是我们不希望在非活动div中显示内容。

请尝试添加到文档中：

$('a.morelink').click(function(){
    $(this).parent().find('span').toggle();
    $(this).parent().parent().find('span.moreellipses').toggle();
    $(this).parent().find('a').text($(this).text() == '[+]' ? "[-]" : "[+]");
    return false;
});

并替换：

$(".row1").height(maxHeight);

与

$(".row1").css({'min-height':maxHeight,'height':'auto'});

因此，您的代码可能是：

  $(document).ready(function() { var maxHeight = 0; $(".row1").each(function() { if ($(this).height() > maxHeight) { maxHeight = $(this).height(); } }); $(".row1").css({ 'min-height': maxHeight, 'height': 'auto' }); }); $(document).ready(function() { var ellipsestext = "..."; var moretext = "[+]"; var lesstext = "[-]"; $('.more1').each(function() { var showChar = 172; var content = $(this).html(); if (content.length > showChar) { var c = content.substr(0, showChar); var h = content.substr(showChar, content.length - showChar); var html = c + '<span class="moreellipses">' + ellipsestext + ' </span><span class="morecontent"><span>' + h + '</span> <a href="" class="morelink">' + moretext + '</a></span>'; $(this).html(html); } }); $('.more2').each(function() { var showChar = 150; var content = $(this).html(); if (content.length > showChar) { var c = content.substr(0, showChar); var h = content.substr(showChar, content.length - showChar); var html = c + '<span class="moreellipses">' + ellipsestext + ' </span><span class="morecontent"><span>' + h + '</span> <a href="" class="morelink">' + moretext + '</a></span>'; $(this).html(html); } }); $('a.morelink').click(function() { $(this).parent().find('span').toggle(); $(this).parent().parent().find('span.moreellipses').toggle(); $(this).parent().find('a').text($(this).text() == '[+]' ? "[-]" : "[+]"); return false; }); });
