Question

我尝试在 asp.net 应用程序中实现 Jquery.Spell.Checker 但它给出错误，如下图所示。

有人建议我如何解决它。

PS：

我已经在我的应用程序中进行了更改但仍然无法正常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：

<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")

                innerDocument: false            // if you want the badwords highlighted in the html then set to true
        })
        .spellchecker("check", function(result){

                $(".loading").hide();

                if (result) {
                        alert('There are no incorrectly spelt words.');
                }
        });
});

Answer 1

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 页面并向其中添加以下代码

<%@ 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”

对你来说可能有点晚了，但对于任何试图解决这个问题的人来说，Jack Yang 已经制作了一个 checkpelling.php 的 ASP 实现，可以在

Answer 3

该插件仅执行客户端代码。您必须向它提供 ASP 脚本的 URL。
