Jquery plugins 我们可以使用asp.net web服务按语法运行jquery拼写检查器吗？
我已经研究了很长一段时间，现在为textbox和多行textbox寻找合适的拼写检查器 我可以看到这个功能是为firefox内置的，但在chrome中并不存在 我正在检查所有的拼写检查演示，这是由 jQuerySpellChecker-badsyntax，我发现它非常好用 这里是链接 但我这里的问题是——拼写检查器使用php Web服务，我想在我的ASP.net Web应用程序中使用它 有什么办法可以让我使用asp.net web服务运行它吗Jquery plugins 我们可以使用asp.net web服务按语法运行jquery拼写检查器吗？,jquery-plugins,spell-checking,Jquery Plugins,Spell Checking,我已经研究了很长一段时间，现在为textbox和多行textbox寻找合适的拼写检查器 我可以看到这个功能是为firefox内置的，但在chrome中并不存在 我正在检查所有的拼写检查演示，这是由 jQuerySpellChecker-badsyntax，我发现它非常好用 这里是链接 但我这里的问题是——拼写检查器使用php Web服务，我想在我的ASP.net Web应用程序中使用它 有什么办法可以让我使用asp.net web服务运行它吗 请为我提供一个解决方案。我是该插件的作者，非常希望

谢谢你的回复。我真的很感谢你为插件所做的一切工作。这个插件的效果非常好。如果我们以某种方式为ASP.NETWeb服务实现它，它将非常棒。我正在努力。如果我有突破，我肯定会分享代码。另外，请让我知道php web服务采用的参数是什么，以及我们从中得到的响应是什么。提前谢谢你好，维克多。。我将检查您提供的代码，看看它是如何工作的。。ThanksI已经发现jquery spellchecker希望从web服务返回以下格式的json：“{'Output'：'success'，'data'：[“incorrectoWord01，incorrectoWord02”]}”方法返回错误单词和数据作为[“suggest01，suggest02”]为检索分段的方法返回的建议词的格式Victor非常感谢。。我用firebug检查了同样的问题：）。。我已经修改了代码，以便使用jquery拼写检查器，它的语法是badbe。我将很快分享代码
