HTML5 提供了許多方便的功能，其中只讀文本框就是其中之一。只讀文本框的作用是允許用戶查看文本框的內(nèi)容，但是不允許編輯，這對于一些需要保密的信息來說是非常有用的。 下面就是一個 HTML5 只讀文本框的例子：

請閱讀下面的銷售協(xié)議：
銷售協(xié)議：
本合同自雙方簽署之日起生效。甲方同意將下列物品出售給乙方，并保證該物品的合法性和完整性。
1.物品名稱：蘋果iPhone11
2.物品數(shù)量：1臺
3.物品價格：人民幣5999元

在上面的代碼中，我們使用了

標簽來包裹代碼塊，這樣代碼塊中的空格和換行等都會保留下來。而在代碼塊中，我們首先使用了
標簽來分段，然后使用標簽來創(chuàng)建文本框，并將它設置為只讀屬性（readonly）。最后，將銷售協(xié)議的內(nèi)容寫入文本框。
這樣，用戶就可以查看銷售協(xié)議的內(nèi)容，但是無法修改文本框中的內(nèi)容。如果用戶需要對文本框中的內(nèi)容進行修改，只需將只讀屬性去掉即可。
HTML5 的只讀文本框功能為用戶保密信息提供了更好的保障，同時也方便了用戶查看信息。它的應用已經(jīng)被廣泛地運用在各種網(wǎng)站和應用程序中，為用戶的體驗提供了更加完善的保障。</div><div   id="frf7rbn"   class="share"></div><div   id="5xvpjvx"   class="Prev_Next"><div   id="fpfdvvv"   class="box">上一篇<a href="http://52shenghuonet.cn/post/1086566.html">html5發(fā)光圖片代碼</a></div><div   id="fdz5fft"   class="box">下一篇<a href="http://52shenghuonet.cn/post/1086546.html">html5原生代碼</a></div></div></div><div   id="zxn7npb"   class="related related-list"><h5>相關文章</h5><ul><li><a href="http://52shenghuonet.cn/post/1469806.html">html基礎教程都有哪些標題，詳細說明</a><span>08-04</span></li><li><a href="http://52shenghuonet.cn/post/1299849.html">html畫八卦動態(tài)代碼</a><span>06-30</span></li><li><a href="http://52shenghuonet.cn/post/1298508.html">html電子郵件鏈接怎么設置</a><span>06-30</span></li><li><a href="http://52shenghuonet.cn/post/1298599.html">html電影代碼教程</a><span>06-30</span></li><li><a href="http://52shenghuonet.cn/post/1298398.html">html電子商城源代碼</a><span>06-30</span></li><li><a href="http://52shenghuonet.cn/post/1298609.html">html電子相冊代碼送女友</a><span>06-30</span></li><li><a href="http://52shenghuonet.cn/post/1298930.html">html電影網(wǎng)頁源代碼</a><span>06-30</span></li><li><a href="http://52shenghuonet.cn/post/1297409.html">html田字格布局怎么設置</a><span>06-30</span></li><li><a href="http://52shenghuonet.cn/post/1297503.html">html電商網(wǎng)站開源代碼</a><span>06-30</span></li><li><a href="http://52shenghuonet.cn/post/1298538.html">html電子郵箱鏈接代碼</a><span>06-30</span></li><li><a href="http://52shenghuonet.cn/post/1298495.html">html電子郵件鏈接代碼</a><span>06-30</span></li><li><a href="http://52shenghuonet.cn/post/1299073.html">html電影院訂票代碼</a><span>06-30</span></li><li><a href="http://52shenghuonet.cn/post/1297960.html">html電子書翻頁效果代碼</a><span>06-30</span></li><li><a href="http://52shenghuonet.cn/post/1298838.html">html電影介紹網(wǎng)站代碼</a><span>06-30</span></li><li><a href="http://52shenghuonet.cn/post/1299411.html">html電腦特效代碼</a><span>06-30</span></li><li><a href="http://52shenghuonet.cn/post/1191004.html">html常用顏色代碼</a><span>06-09</span></li><li><a href="http://52shenghuonet.cn/post/1187759.html">html字加邊框代碼</a><span>06-04</span></li><li><a href="http://52shenghuonet.cn/post/667426.html">HTML設置字號（讓你的網(wǎng)頁字體更加美觀）</a><span>04-13</span></li><li><a href="http://52shenghuonet.cn/post/668363.html">未能識別輸入的關鍵詞，請重新輸入</a><span>04-15</span></li><li><a href="http://52shenghuonet.cn/post/1092873.html">html5表格位置代碼</a><span>05-14</span></li><li><a href="http://52shenghuonet.cn/post/1190398.html">html嵌套有序列表的代碼</a><span>06-08</span></li><li><a href="http://52shenghuonet.cn/post/722856.html">outlook怎樣設置html（詳細講解outlook的HTML設置方法）</a><span>04-20</span></li><li><a href="http://52shenghuonet.cn/post/723016.html">scroll html代碼，讓你的網(wǎng)頁更加流暢</a><span>04-20</span></li><li><a href="http://52shenghuonet.cn/post/715959.html">html如何使用顏色橫線代碼實現(xiàn)網(wǎng)頁美化</a><span>04-24</span></li><li><a href="http://52shenghuonet.cn/post/725877.html">如何設置HTML網(wǎng)頁地址（詳細步驟教你輕松搞定）</a><span>04-20</span></li><li><a href="http://52shenghuonet.cn/post/1066719.html">1行2列html表格代碼</a><span>05-22</span></li><li><a href="http://52shenghuonet.cn/post/1087268.html">html5外邊框代碼</a><span>05-15</span></li><li><a href="http://52shenghuonet.cn/post/1297436.html">html申請表代碼</a><span>06-30</span></li><li><a href="http://52shenghuonet.cn/post/594892.html">HTML透明度怎么設置（詳解HTML中設置透明度的方法）</a><span>04-03</span></li><li><a href="http://52shenghuonet.cn/post/594852.html">html語言代碼怎么學？</a><span>04-03</span></li></ul></div></div></div></div><div   class="rp5xpvx"   id="footer"><div   id="n7hdfjv"   class="copyright"><div   id="pbrjnnz"   class="container"><p>老白網(wǎng)絡 (http://52shenghuonet.cn/) 前端 后端 zblog主題.<a href="http://52shenghuonet.cn/sitemap/post.html">網(wǎng)站地圖</a><a href="http://52shenghuonet.cn/sitemap/post.xml">xml</a></p><span>Powered By Z-BlogPHP</span></div></div></div><div   id="n7vntfr"   class="bottom_tools"><a id="scrollUp" href="javascript:;" title="返回頂部"><i class="fa fa-angle-up"></i></a></div><script type="text/javascript" src="http://cdn.staticfile.org/jquery/2.2.4/jquery.min.js"></script><script src="http://cdn.yzktw.com.cn/zb_users/theme/ydproduct/script/ads.js" type="text/javascript"></script><script src="http://cdn.yzktw.com.cn/zb_users/theme/ydproduct/script/common.min.js" type="text/javascript"></script><script src="http://cdn.staticfile.org/prettify/r298/prettify.min.js" type="text/javascript"></script><script>jQuery(window).load(function(){jQuery("pre").addClass("prettyprint");prettyPrint();});</script><div   class="d55phxz"   id="ly_cache" data-id="1086582"></div>
