jquery - 在 textArea 中使用完美的滚动条插件

问题描述

您好朋友，我想在 Angular 的 textarea 中使用完美的滚动条，请帮助我。

<div>
                <textarea class="form-control textarea-box comment-box" maxlength="1000" [formControl]="form.controls['comment']" ></textarea>
                </div>
                <span class="maxTxt"><strong>Note:</strong> {{showMessage}}</span>

标签： jquery

解决方案

您可以仅定位h2s 的直接子级#faqs，从而排除 , 的子级aside的s #faqs > h2：

（我用背景颜色替换了.plusand.minus样式，因此更改将在 SO 上可见）

$("#faqs > h2").addClass('plus');
$("div").addClass('close');
$("#faqs > h2").click(function() {
  $(this).toggleClass('minus');
}); // end click
$("div").click(function() {
  $(this).toggleClass('open');
}); // end click
* {
  margin: 0;
  padding: 0;
}

body {
  font-family: Verdana, Arial, Helvetica, sans-serif;
  font-size: 100%;
  margin: 20px;
  padding: 10px;
}

section {
  padding: 15px 25px;
  width: 650px;
  margin-top: 20px;
  margin-left: 25px;
}

h1 {
  font-size: 150%;
}

h2 {
  font-size: 120%;
  padding: .25em 0 .25em 25px;
  cursor: pointer;
}


/* classes that you will use */

.plus {
  background-color: yellow
}

.minus {
  background-color: red
}

.close {
  display: none;
}

.open {
  display: block;
}

ul {
  padding-left: 45px;
}

li {
  padding-bottom: .25em;
}

p {
  padding-bottom: .25em;
  padding-left: 25px;
}

aside {
  margin-top: 50px;
}

aside h2,
header h2 {
  cursor: auto;
}
