javascript - 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 下拉菜单构建一些 jquery Accordion 效果；请看例子JSFIDDLE .这里我想要的实际上是点击('+')按钮我想显示内容的扩孔部分。那时同一行中的其他 div 应该采用与事件 div 相同的高度，但我们不想显示非事件 div 中的内容。

准备好尝试添加到您的文档中:

$('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'});

所以你的代码可以是:

	$(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;
	  });
	});

          I understand this is a privilege that is earned by gaining 2,000 reputation on the site. As far as I can see, that is the only requirement - there doesn't seem to be any restrictions on where you get that rep from. For instance, I got mine mostly through
          answers and a few questions - I think I may have made one suggested edit before gaining this privilege which allows me to edit anything, without peer review..
          <br>Please note - I'm not trying to suggest that there are roving bands of 2K users rampantly defiling posts left and right; rather this is more focussed on introducing a learning curve for edits, rather than allowing users who may have no idea
          how to edit a post edit anything.
