在Create.aspx中添加 KindEditor的引用
<script src="http://www.cnblogs.com/Scripts/KindEditor/kindeditor.js" charset="utf-8" type="text/javascript"></script>
<script type="text/javascript">
KE.show({
id: 'editor',
imageUploadJson: '/Blog/UploadImage'
});
</script>
- id：对应textarea id
- imageUploadJson：提供上传图片的处理程序，这里指向 Blog中的UploadImage
表单内容如下：
<% using (Html.BeginForm())
{%>
<%: Html.ValidationSummary(true) %>
<fieldset>
<legend>Fields</legend>
<div class="editor-label">
<%: Html.LabelFor(model => model.Title) %>
</div>
<div class="editor-field">
<%: Html.TextBoxFor(model => model.Title) %>
<%: Html.ValidationMessageFor(model => model.Title) %>
</div>
<div class="editor-label">
<%: Html.LabelFor(model => model.Content) %>
</div>
<div class="editor-field">
<%: Html.TextAreaFor(model => model.Content, new { id="editor",rows="15",cols="85"})%>
<%: Html.ValidationMessageFor(model => model.Content) %>
</div>
<p>
<input type="submit" value="Create" />
</p>
</fieldset>
<% } %>
<div>
<%: Html.ActionLink("Back to List", "Index") %>
</div>
以上实现方法参考官方包中的upload_json.ashx实现，关键在 Json格式
