UIWebView execCommand剪切，复制，粘贴 [英] UIWebView execCommand Cut, Copy, Paste

问题描述

我似乎无法将execCommand用于剪切，复制，粘贴以在contentEditable设置为true的UIWebView中工作。我可以使用selectAll命令选择文本，但剪切，复制和粘贴不起作用。

I can't seem to get the execCommand for cut, copy, paste to work in a UIWebView that has contentEditable set to true. I am able to select the text using selectAll command but cut, copy, and paste do not work.

这是我正在使用的代码：

This is the code I'm using:

[webView stringByEvaluatingJavaScriptFromString:@"document.execCommand('cut', false, null)"];

我还需要做些什么才能让剪贴板操作正常工作吗？

Is there something else I need to do to allow clipboard operations to work?

推荐答案

按照之前的评论剪切，复制，粘贴命令似乎不起作用，所以我设法实现了相同的操作：

As per previous comments cut, copy, paste commands don't appear to work so I managed to achieve the same operations like so:

- (void)cut
{
    NSString *selection = [self.webView stringByEvaluatingJavaScriptFromString:@"window.getSelection().toString()"];
    [webView stringByEvaluatingJavaScriptFromString:@"document.execCommand('delete', false, null)"];
    [UIPasteboard generalPasteboard].string = selection;
}

- (void)paste
{
    NSString *text = [UIPasteboard generalPasteboard].string;
    [webView stringByEvaluatingJavaScriptFromString:[NSString stringWithFormat:@"document.execCommand('insertHTML', false, '%@')", text]];
    [UIPasteboard generalPasteboard].string = @"";
}
