我已经在我的应用程序中进行了更改，但仍然无法工作并按照上图显示警报消息。如果我丢失了某些内容，请告诉我。下面给出的代码:

<link href="JQuerySpellChecker/spellchecker.css" rel="stylesheet" type="text/css" />
<script src="JavaScript/jquery-1.4.4.min.js" type="text/javascript"></script>
<script src="JQuerySpellChecker/jquery.spellchecker.js" type="text/javascript"></script>

CSS:

<style type="text/css">
body {
        margin: 1em;
        font-family: 'lucida grande',helvetica,verdana,arial,sans-serif;
}
#textarea-example {
        width: 562px;
}
textarea {
        font-size: 90%;
        margin-bottom:10px;
        padding: 5px;
        border: 1px solid #999999;
        border-color: #888888 #CCCCCC #CCCCCC #888888;
        border-style: solid;
        height: 20em;
        width: 550px;
}
button {
        font-size: 90%;
        cursor: pointer;
}
.loading {
        padding: 0.5em 8px;
        display: none;
        font-size: small;
}
</style>

HTML:

<div id="textarea-example">
    <p>
        <label for="text-content">Add your own text and check the spelling.</label>
    </p>
    <textarea id="text-content" rows="5" cols="25"></textarea>
    <div>
        <button id="check-textarea">Check Spelling</button>&nbsp;
        <span class="loading">loading..</span>
    </div>
</div>

JAVASCRIPT:

// check the spelling on a textarea
$("#check-textarea").click(function(e){
        e.preventDefault();
        $(".loading").show();
        $("#text-content")
        .spellchecker({
                url: "CheckSpelling.aspx",       // default spellcheck url

                innerDocument: false            // if you want the badwords highlighted in the html then set to true
        })
        .spellchecker("check", function(result){
                // spell checker has finished checking words
                $(".loading").hide();
                // if result is true then there are no badly spelt words
                if (result) {
                        alert('There are no incorrectly spelt words.');
                }
        });
});

您需要自己编写一个包含 PHP 服务器端文件的 ASP 版本。本质上，服务器端组件将请求代理给 Google 或使用 PHP 拼写检查器。由于您并不真正想要转换整个 Pspell 库，因此我建议简单地结束对 Google 拼写检查站点的调用。

即创建一个ASPX页面并添加以下代码

<%@ Import Namespace="System.Xml" %>
<script language="C#" runat="server">
public void Page_Load(Object src, EventArgs e)
{
    var str = Request["str"];
    if (str != null)
    {
        var url = "https://www.google.com";
        var path = "/tbproxy/spell?lang=en&hl=en";

        // setup XML request
        var xml = "<?xml version=\"1.0\" encoding=\"utf-8\" ?>";
        xml += "<spellrequest textalreadyclipped=\"0\" ignoredups=\"0\" ignoredigits=\"1\" ignoreallcaps=\"1\">";
        xml += "<text>" + str + "</text></spellrequest>";
        ASCIIEncoding encoding = new ASCIIEncoding();
        byte[] data = encoding.GetBytes(xml);

        System.Net.HttpWebRequest request = (System.Net.HttpWebRequest)System.Net.WebRequest.Create(url + path);
        request.Method = "POST";
        request.ContentType = "text/xml";
        request.ContentLength = data.Length;
        System.IO.Stream stream = request.GetRequestStream();

        // Send the data.
        stream.Write(data, 0, data.Length);
        stream.Close();

        // Get the response.
        System.Net.WebResponse response = request.GetResponse();

        // Get the stream containing content returned by the server.
        stream = response.GetResponseStream();

        // Open the stream using a StreamReader for easy access.
        System.IO.StreamReader reader = new System.IO.StreamReader(stream);

        // Read the content.
        string responseFromServer = reader.ReadToEnd();

        // Clean up the streams.
        reader.Close();
        stream.Close();
        response.Close();

        Response.ContentType = "text/xml";
        MatchCollection result = Regex.Matches(responseFromServer, "<c o=\"([^\"]*)\" l=\"([^\"]*)\" s=\"([^\"]*)\">([^<]*)</c>");
        if (result != null && result.Count > 0)
            Response.Write(result[0].Value);
    }
    Response.Write("Failed");
}
</script>

然后更改 js 中的调用以调用新的 aspx 文件而不是“checkspelling.php”
