這就是我想爲我的項目做的事情。我有一個簡單的內容框包裝在一個div標籤。有段落加入，並有自己的規則編號。我已經設置了邊距，填充，等等。然後在底部，我添加了一個典型的提交按鈕。我標記的內容顯示更多。隨着我的內容框中發生溢出，我想增加高度，以便它可以顯示文本的其餘部分。但是，當我用if/else語句在匿名函數中添加onclick命令時，事情會變得有些不和諧。我的提交按鈕的onclick函數發生了什麼？
以下是HTML代碼。
var content = document.getElementById('contentbox');
var button = document.getElementById('showMore');
button.onclick = function() {
\t if(content.className == "open") {
\t \t content.className = "";
\t } else {
\t \t content.className = "open";
\t }
};body {
\t padding:0;
\t margin:0;
\t font-family:sans-serif;
}
#contentbox {
\t margin:100px 300px 100px 300px;
\t border:1px solid black;
\t padding:5px 0px 5px 20px;
\t max-height:200px;
\t overflow:hidden;
\t background:silver;
\t border-radius:10px;
}
#contentbox.open {
\t max-height:1000px;
\t overflow:visible;
}
#content {
\t color:white;
\t font-size:20px;
\t text-indent:30px;
}
#showMore {
\t margin-left:auto;
\t margin-right:auto;
\t display:block;
\t background:gray;
\t font-size:40px;
\t text-transform:uppercase;
\t font-family:impact;
\t color:silver;
\t transition:all 0.5s ease-in-out;
}
#showMore:hover {
\t color:gray;
\t background:silver;
\t cursor:pointer;

this is a bunch of text for you to read and Game of Thrones is an American fantasy drama television series created by David Benioff and D. B. Weiss. It is an adaptation of A Song of Ice and Fire, George R. R. Martin's series of fantasy novels, the first of which is A Game of Thrones. It is filmed at Titanic Studios in Belfast, on location in the United Kingdom, and in Croatia, Iceland, Malta, Morocco, Spain, and the United States. The series premiered on HBO in the United States on April 17, 2011, and its sixth season ended on June 26, 2016. The series was renewed for a seventh season,[1] which is scheduled to premiere on July 16, 2017.[2] The series will conclude with its eighth season in 2018 </p>
<p id='content'> Set on the fictional continents of Westeros and Essos, Game of Thrones has several plot lines and a large ensemble cast. The first story arc follows a dynastic conflict among competing claimants for succession to the Iron Throne of the Seven Kingdoms, with other noble families fighting for independence from the throne. The second covers attempts to reclaim the throne by the exiled last scion of the realm's deposed ruling dynasty; the third chronicles the threat of the impending winter and the legendary creatures and fierce peoples of the North. </p>
<p id='content'> Game of Thrones has attracted record viewership on HBO and has a broad, active, international fan base. It has been acclaimed by critics, particularly for its acting, complex characters, story, scope, and production values, although its frequent use of nudity and violence (including sexual violence) has attracted criticism. The series has received 38 Primetime Emmy Awards, including Outstanding Drama Series in 2015 and 2016, more than any other primetime scripted television series. Its other awards and nominations include three Hugo Awards for Best Dramatic Presentation (2012–2014), a 2011 Peabody Award, and four nominations for the Golden Globe Award for Best Television Series – Drama (2012 and 2015–2017). Of the ensemble cast, Peter Dinklage has won two Primetime Emmy Awards for Outstanding Supporting Actor in a Drama Series (2011 and 2015) and the Golden Globe Award for Best Supporting Actor – Series, Miniseries or Television Film (2012) for his performance as Tyrion Lannister. Lena Headey, Emilia Clarke, Kit Harington, Maisie Williams, Diana Rigg, and Max von Sydow have also received Primetime Emmy Award nominations for their performances in the series. </p>
