前言
关于复制粘贴的功能,好像不用劳师动众的写后端代码,JS就可以,但正如大家所知道的,兼容性问题,当然这么通用的功能怎么可能没有一个通用的方案呢,于是便找到了一款jquery插件 jquery.clip, perfect!但本篇并不是写如何使用jquery.clip,而是通过.net 的Clipboard类来实现。
代码实现
一、创建WebAPI,代码如下
using System.Windows.Forms; using System.Threading; namespace JYZS.Api { public class ClipboardController : ApiController { [HttpGet] public string CopyToClipboard(string content) { Thread newThread = new Thread(new ThreadStart(() => { _CopyToClipboard(content); })); newThread.SetApartmentState(ApartmentState.STA); newThread.Start(); //newThread.Join();//阻塞调用线程,直到被调用线程结束 return ""; } private void _CopyToClipboard(string content) { System.Windows.Forms.Clipboard.SetText(content); } [HttpGet] public string PasteFromClipboard() { string text = ""; try { Thread newThread = new Thread(new ThreadStart(() => { text = _PasteFromClipboard(); })); newThread.SetApartmentState(ApartmentState.STA); newThread.Priority = ThreadPriority.Highest; newThread.Start(); newThread.Join();//阻塞调用线程,直到被调用线程结束 return text; } catch { return ""; } } private string _PasteFromClipboard() { return System.Windows.Forms.Clipboard.GetText(); } } }
二、前端调用
function fn_CopyToClipboard() { $.ajax({ type: ‘GET‘, url: ‘/api/Clipboard/CopyToClipboard‘, data: { content: $.trim($(‘#Content‘).val()) }, success: function (msg) { if (msg == null || msg == ‘‘) { alert(‘已复制到剪切板‘); } else alert(msg); }, error: function (err) { alert(‘复制到剪切板失败‘); } }); } function fn_PasteFromClipboard() { $.ajax({ type: ‘GET‘, url: ‘/api/Clipboard/PasteFromClipboard‘, data: { }, success: function (msg) { if (msg == null || msg == ‘‘) { alert(‘获取剪切板数据失败‘); } else alert(msg); }, error: function (err) { alert(‘获取剪切板数据失败‘); } }); }
