AJAX HTML编辑器扩展程序上传图像显示为空白 [英] AJAX Html Editor Extender upload image appearing blank

问题描述

使用AJAX 4（最新版本），我一直在与html编辑器扩展程序一起尝试上传带有文本的图像，我已经上传了Image，但是它显示为空白，并且在查看源代码时，图像的源代码是也为空白（下图）如何解决此上传我选择的图像？

Using AJAX 4 (latest version) I have been working with the html editor extender trying to upload images with text, I have got the Image to upload however it appears blank and when looking at the source, the source of the image is also blank (image below) how do I resolve this upload my selected image?

推荐答案

在HtmlEditorExtender中包含ImageUploadComplete事件的事件处理程序。

Include in HtmlEditorExtender an event handler for the ImageUploadComplete event.

<ajaxToolkit:HtmlEditorExtender
    OnImageUploadComplete="MyHtmlEditorExtender_ImageUploadComplete"
    ...

在ImageUploadComplete事件处理程序中，您需要做两件事：

Within the ImageUploadComplete event handler, you need to do two things:

1）保存上传的图像

2）提供保存图像的URL，以便可以在HtmlEditorExtender中显示图像

1) Save the uploaded image
2) Provide the URL to the saved image so the image can be displayed within the HtmlEditorExtender

protected void MyHtmlEditorExtender_ImageUploadComplete(
     object sender, AjaxFileUploadEventArgs e)
{
     // Generate file path
     string filePath = "~/Images/" + e.FileName;

     // Save uploaded file to the file system
     var ajaxFileUpload = (AjaxFileUpload)sender;
     ajaxFileUpload.SaveAs(MapPath(filePath));

     // Update client with saved image path
     e.PostedUrl = Page.ResolveUrl(filePath);
}
