在用户将'n'粘贴复制到文本字段后，如何更新视图模型?

I am working on a website that auto populates search result in a table after user entered some text in the input text box (similar to google instant search).

我正在开发一个网站，在用户在输入文本框(类似于谷歌即时搜索)中输入一些文本后自动将搜索结果填充到表格中。

I managed to get knockout js to update view model as user enters information by adding

当用户通过添加输入信息时，我设法让knockout js更新视图模型

valueUpdate: 'afterkeydown'

valueUpdate:“afterkeydown”

into my data-bind attribute, however, I also need to handle the case where user right click and paste some text into the textbox so I tried:

然而，在我的数据绑定属性中，我还需要处理用户右击并将一些文本粘贴到文本框中的情况，所以我尝试了:

valueUpdate: ['afterkeydown','mouseup']

valueUpdate:[' afterkeydown ',' mouseup ']

but that didn't work and when I tried to read the value of the text box through the view model I kept getting the old value until I tab out of the input text box.

但这不起作用，当我试图通过视图模型读取文本框的值时，我一直在获取旧值，直到我从输入文本框中跳出来。

Anyone know how can I fix this?

有人知道我怎么修复吗?

You can use valueUpdate:'input'. I have testet it to work in Opera, Firefox and Chrome. I'm on a Linux box, so I can't test it in IE. Check this fiddle

您可以使用valueUpdate:“输入”。我在Opera、Firefox和Chrome上都有测试。我在一个Linux盒子上，所以我不能在IE中测试它。检查这个小提琴

UPDATE: I have now testet it in IE8, and it doesn't work. But using the following seems to work.

更新:我现在在IE8中测试了它，但是它不工作。但是使用以下方法似乎是有效的。

valueUpdate:['afterkeydown','propertychange','input']

Thanks to Michael Best for his comment about this :) I have updated the fiddle

感谢迈克尔·贝斯特的评论:)我更新了小提琴

UPDATE okt 2014: As kzh mention in a comment below, in one of the later versions of Knockout.js the textInput binding was added. This binding handles this scenario and has build in browser quirks handling http://knockoutjs.com/documentation/textinput-binding.html

更新okt 2014:正如kzh在下面的评论中提到的，在Knockout的一个后续版本中。添加了textInput绑定。此绑定处理此场景，并具有内置浏览器怪癖，处理http://knockoutjs.com/documentation/textinput-binding.html
