Question

我在评论div中遇到HTML标记问题，当我插入something标记时，没有显示更多文字链接。它与纯文本一起工作正常。我想插入富文本，但它不起作用。

CSS

body, input{
    font-family: Calibri, Arial;
    margin: 0px;
    padding: 0px;
}
a {
    color: #0254EB
}
a:visited {
    color: #0254EB
}
#header h2 {
    color: white;
    background-color: #00A1E6;
    margin:0px;
    padding: 5px;
}
.comment {
    width: 400px;
    background-color: #f0f0f0;
    margin: 10px;
}
a.morelink {
    text-decoration:none;
    outline: none;
}
.morecontent span {
    display: none;

}

的Javascript

$(document).ready(function() {
    var showChar = 100;
    var ellipsestext = "...";
    var moretext = "more";
    var lesstext = "less";
    $('.more').each(function() {
        var content = $(this).html();

        if(content.length > showChar) {

            var c = content.substr(0, showChar);
            var h = content.substr(showChar-1, content.length - showChar);

            var html = c + '<span class="moreelipses">'+ellipsestext+'</span>&nbsp;<span class="morecontent"><span>' + h + '</span>&nbsp;&nbsp;<a href="" class="morelink">'+moretext+'</a></span>';

            $(this).html(html);
        }

    });

    $(".morelink").click(function(){
        if($(this).hasClass("less")) {
            $(this).removeClass("less");
            $(this).html(moretext);
        } else {
            $(this).addClass("less");
            $(this).html(lesstext);
        }
        $(this).parent().prev().toggle();
        $(this).prev().toggle();
        return false;
    });
});

Answer 1

这是因为你正在考虑var content = $(this).html();。 html有一个，当你拿到substr时，你会得到格式错误的html而没有结束标记（例如Some Text）。不同的浏览器将以不同方式处理格式错误的HTML。您的morelink链接会被置于之外，并且切换最终会将其隐藏起来。请改用var content = $(this).text();或找一个可以更好地处理此问题的插件。

插件版（新功能）：

$.fn.showHideParagraph = function(settings){
    var config = $.extend({},  $.fn.showHideParagraph.config, settings);
    $(this).on({click: function () {
        var $this = $(this);
        if ($this.hasClass('less')) {
            $this.removeClass('less').html(config.moreText);
        } else {
            $this.addClass('less').html(config.lessText);
        }

        $this.parent().siblings('p:not(:first)').animate({opacity: 'toggle', height: 'toggle'});
        return false;
    }
    }, '.morePLink');

    return this.each(function () {
        var $this = $(this);
        if($this.hasClass("shortenedP")) return;

        $this.addClass("shortenedP");
        var paragraphs = $this.children('p');
        if (paragraphs.length > config.paragraphShowed) {
            paragraphs.not(":first").hide();

            paragraphs.first().append(" ...");
            var moreLess = '<span><a href="#" class="morePLink">'  + config.moreText + '</a></span>';
            $this.append(moreLess);
        }
    });
};

$.fn.showHideParagraph.config = {
    paragraphShowed: 1,
    ellipsesText: "...",
    moreText: 'more',
    lessText: 'less'
};

这支持p，你可以配置p显示的数量。
