Question

我正在尝试创建自己的读取更多/更少功能以进行评论。 ReadMore ReadLess Image

在开发过程中，我遇到了一个问题。假设，我有3条评论（参见第一张图片）超过500个字符。在这些评论中未显示全文/全文，因此我添加 ReadMore 链接以阅读所有评论。仅显示我点击的那个类..

问题：当我点击其中一个链接 ReadMore 时，它会显示全部三条全文注释而不是仅向我显示单击的类文本。问题图片：img.ctrlv.in/img/16/03/12/56e4110ccb82d.png

现在将我的代码段粘贴到此处

function mangeText(text) {
  var minCharLength = 50;
  var readL ="Read Less";
  var readM = "Read More";
  var txt = text,
    txtLength = 0,
    totLength = "";
  var startDisplayText = "",
    startupCont = "",
    hiddenContent = "";
  txtLength = txt.length;
  for (var i = 0; i < minCharLength; i++) {
    totLength += txt[i];
    //console.log("["+i+"] "+totLength);
  }
  if (txt.length >= (minCharLength + 50)) {
    startupCont += "<span class='yughi501 _po2075 tetb_apndShw umoriRut' style='display:inline-block'> " + totLength +
      " <span>" +
      "<a href='#' onclick='ReadMoreLess()' class='txb_rdM _d1e301 _oijd51 _pedu' style='display:inline-block'> " +
      readM +
      "</a>" +
      "</span>" +
      "</span>";

    hiddenContent = "<span class='yughi411 _po21075 _umori120Rut tetb_apndhd' style='display:none'> " + txt +
      " <span>" +
      "<a href='#' onclick='ReadMoreLess()' class='txb_rdL  _pedu'> " +
      readL +
      " </a>" +
      "</span>" +
      "</span>";
    txt = startupCont;
    txt += hiddenContent;
  }
  return txt;
}

function ReadMoreLess(){
			
			if($(".tetb_apndhd").css("display") == "none"){
				console.log("IF");
				$(".tetb_apndhd").css({"display":"inline-block"});
				$(".tetb_apndShw").css({"display":"none"});
			}else if(($(".tetb_apndhd").css("display") == "inline-block")){
				console.log("ELSE IF");
				$(".tetb_apndShw").css({"display":"inline-block"});
				$(".tetb_apndhd").css({"display":"none"});
			}
		}

$(".apndbtn").click(function (){
	var txt = mangeText($(".txt").val());
	$(".dclr").append(txt);
});

.txt{width:300px;height:150px;resize:none}

我的解决方案：

//i[@class="fa fa-lg fa-check-circle green"]/preceding-sibling::a[@ng-click="acceptNotification(friendInvite, 'friend')"]

我删除了链接上的onClick事件，并将此代码添加到.apndbtn点击功能：

p = Pipeline([
    ("vectorizer", CountVectorizer()),
    ("selector", SelectPercentile(percentile=20)),
    ("nb", MultinomialNB())
])

p.fit(X, y)
joblib.dump(p, 'skclassif.pkl', compress = 1)
print(p.predict(["I hate this car"]))

尝试在单个类Jquery或js上应用事件
