将tinyMCE内容替换为原始文本

本文关键字：原始 文本 替换 tinyMCE | 更新日期: 2023-09-27 18:20:09

我正在使用tinyMCE根据自己的意愿更改内容。但是当我保存内容时，结果是HTML标记。像

<p>int a,b,c;</p> <p>c=a+b;</p>

原始文本为

int a,b,c;
c=a+b;

这是我的观点

Create.cshtml:

<script type="text/javascript">
        // Initialize your tinyMCE Editor with your preferred options
        tinyMCE.init({
            // General options
            mode: "textareas",
            theme: "modern",
            // Theme options
            theme_advanced_buttons1: "save,newdocument,|,bold,italic,underline,strikethrough,|,justifyleft,justifycenter,justifyright,justifyfull,|,styleselect,formatselect,fontselect,fontsizeselect",
            theme_advanced_buttons2: "cut,copy,paste,pastetext,pasteword,|,search,replace,|,bullist,numlist,|,outdent,indent,blockquote,|,undo,redo,|,link,unlink,anchor,image,cleanup,help,code,|,insertdate,inserttime,preview,|,forecolor,backcolor",
            theme_advanced_buttons3: "tablecontrols,|,hr,removeformat,visualaid,|,sub,sup,|,charmap,emotions,iespell,media,advhr,|,print,|,ltr,rtl,|,fullscreen",
            theme_advanced_buttons4: "insertlayer,moveforward,movebackward,absolute,|,styleprops,spellchecker,|,cite,abbr,acronym,del,ins,attribs,|,visualchars,nonbreaking,template,blockquote,pagebreak,|,insertfile,insertimage",
            theme_advanced_toolbar_location: "top",
            theme_advanced_toolbar_align: "left",
            theme_advanced_statusbar_location: "bottom",
            theme_advanced_resizing: true,
            // Example content CSS (should be your site CSS)
            content_css: "css/example.css"
        });
    </script>
</head>

@using (Html.BeginForm()) {
    @Html.AntiForgeryToken()
    @Html.ValidationSummary(true)
    <fieldset>
        <legend>tblStackoverFlow</legend>
        <div class="editor-label">
            @Html.LabelFor(model => model.Category)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => model.Category)
            @Html.ValidationMessageFor(model => model.Category)
        </div>
        <div class="editor-label">
            @Html.LabelFor(model => model.Title)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => model.Title)
            @Html.ValidationMessageFor(model => model.Title)
        </div>
        <div class="editor-label">
            @Html.LabelFor(model => model.CodeSnippet)
        </div>
        <div class="editor-field">
            @Html.TextAreaFor(model => model.CodeSnippet)
            @Html.ValidationMessageFor(model => model.CodeSnippet)
        </div>
        <div class="editor-label">
            @Html.LabelFor(model => model.Tags)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => model.Tags)
            @Html.ValidationMessageFor(model => model.Tags)
        </div>
        <div class="editor-label">
            @Html.LabelFor(model => model.Comments)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => model.Comments)
            @Html.ValidationMessageFor(model => model.Comments)
        </div>
        <p>
            <input type="submit" value="Create" />
        </p>
    </fieldset>
}

Index.chtml:

@foreach (var item in Model) {
    <tr>
        <td>
            @Html.DisplayFor(modelItem => item.Category)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.Title)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.CodeSnippet)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.Tags)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.Comments)
        </td>
        <td>
            @Html.ActionLink("Edit", "Edit", new { id=item.Id })            
        </td>
    </tr>
}

在这里，我想替换item.CodeSnippet字段的内容。

C#代码

public ActionResult Index()
        {
            var questions = db.tblStudent.ToList();
            return View(questions);
        }

我尝试使用.replace函数重新填充原始文本

replace(/<p>/g, "'n").replace(/<'/p>/g, "");

但它不起作用。帮帮我。

将tinyMCE内容替换为原始文本

一个解决方案：在控制器中，u r处理值

string x = "<p>a+b=c</p>";
x = x.Replace("<p>", "").Replace("</p>","").Replace("<P>","").Replace("</P>","");

SO：

string yourString = "<p>int a,b,c;</p><p> c + a = b;</p>";
yourString = yourString.Replace("<p>", "").Replace("</p>","").Replace("<P>","").Replace("</P>","");

输出将为：

yourstring = "int a,b,c; c+a=b;";

让我们试试这种方式：

public ActionResult Index()
    {
        var questions = db.tblStudent.ToList();
        // Iterate through each item of the table
        foreach(var tmp in questions)
        {
            tmp.CodeSnippet = tmp.CodeSnippet.Replace("<p>", "").Replace("</p>","").Replace("<P>","").Replace("</P>","");
        }
        return View(questions);
    }

如果要在每个分号后添加换行符，则：

tmp.CodeSnippet = tmp.CodeSnippet.Replace("<p>", "").Replace("</p>","").Replace("<P>","").Replace("</P>","").Replace(";",";'n");

        for (int index=0; index<result.Length; index++)
        {

    }
    catch
    {
        MessageBox.Show("Error");
        return source;
    }
}

你可以添加这个方法，这个方法几乎处理了所有的html标签，然后按照下面的操作

public ActionResult Index()
    {
        var questions = db.tblStudent.ToList();
        // Iterate through each item of the table
        foreach(var tmp in questions)
        {
            tmp.CodeSnippet = StripHTML(tmp.CodeSnippet);
        }
        return View(questions);
    }

Source将Html转换为纯文本
