Element Plus是一套基于Vue 3的桌面端UI库，专为中后台产品而

生。它是对Element UI的升级版本，将会提供更好的功能和更好的性

能。其中，el-form是Element Plus中的一个重要组件，用于快速构

建表单页面。

在使用Element Plus的el-form组件时，经常需要与JavaScript代

码配合使用，来实现表单的验证、提交、重置等功能。熟练掌握el-

form的JavaScript写法，对于开发者来说至关重要。下面将具体介绍

el-form的JavaScript写法，希望对大家有所帮助。

一、基本用法

在使用el-form时，首先需要引入el-form组件，并在data中声明需

要绑定的表单数据，代码如下：

```javascript

lude _include(APP_PATH . 'view/htm/read.htm'); break;*/ default: include _include(theme_load('read', $fid)); break; } } break; case '10': // 主题外链 / thread external link http_location(htmlspecialchars_decode(trim($thread['description']))); break; case '11': // 单页 / single page $attachlist = array(); $imagelist = array(); $thread['filelist'] = array(); $threadlist = NULL; $thread['files'] > 0 and list($attachlist, $imagelist, $thread['filelist']) = well_attach_find_by_tid($tid); $data = data_read_cache($tid); empty($data) and message(-1, lang('data_malformation')); $tidlist = $forum['threads'] ? page_find_by_fid($fid, $page, $pagesize) : NULL; if ($tidlist) { $tidarr = arrlist_values($tidlist, 'tid'); $threadlist = well_thread_find($tidarr, $pagesize); // 按之前tidlist排序 $threadlist = array2_sort_key($threadlist, $tidlist, 'tid'); } $allowpost = forum_access_user($fid, $gid, 'allowpost'); $allowupdate = forum_access_mod($fid, $gid, 'allowupdate'); $allowdelete = forum_access_mod($fid, $gid, 'allowdelete'); $access = array('allowpost' => $allowpost, 'allowupdate' => $allowupdate, 'allowdelete' => $allowdelete); $header['title'] = $thread['subject']; $header['mobile_link'] = $thread['url']; $header['keywords'] = $thread['keyword'] ? $thread['keyword'] : $thread['subject']; $header['description'] = $thread['description'] ? $thread['description'] : $thread['brief']; $_SESSION['fid'] = $fid; if ($ajax) { empty($conf['api_on']) and message(0, lang('closed')); $apilist['header'] = $header; $apilist['extra'] = $extra; $apilist['access'] = $access; $apilist['thread'] = well_thread_safe_info($thread); $apilist['thread_data'] = $data; $apilist['forum'] = $forum; $apilist['imagelist'] = $imagelist; $apilist['filelist'] = $thread['filelist']; $apilist['threadlist'] = $threadlist; message(0, $apilist); } else { include _include(theme_load('single_page', $fid)); } break; default: message(-1, lang('data_malformation')); break; } ?>
