在我的HTML中,我有一个fileUpload按钮,您可以在其中选择要上传文件的文件,然后单击pbcUploadBtn后,它会在Validation.CheckWellFormed(...)
中进行验证。如果文件很好,验证方法返回空字符串,否则返回文件中第一个错误的字符串。如何使用jQuery或js等在我的页面上显示?
<div class="upload">
<asp:FileUpload ID="fileUpload" class="btn" runat="server" />
<asp:Button ID="pbcUploadBtn" class="btn btn-primary" runat="server" Text="Upload" onclick="uploadBtnClick" />
</div>
protected void uploadBtnClick(object sender, EventArgs e)
{
if (this.fileUpload.HasFile)
{
// file gets uploaded to szSaveToPath
Validation.CheckWellFormed(szSaveToPath);
//do things
}
}

在这种情况下,您不需要使用js。 您可以添加标签并更改其文本属性:
<div class="upload">
<asp:FileUpload ID="fileUpload" class="btn" runat="server" />
<asp:Button ID="pbcUploadBtn" class="btn btn-primary" runat="server" Text="Upload" onclick="uploadBtnClick" />
<asp:Label runat="server" ID="lblStatus"></asp:Label>
protected void uploadBtnClick(object sender, EventArgs e)
{
if (this.fileUpload.HasFile)
{
// file gets uploaded to szSaveToPath
lblStatus.Text = Validation.CheckWellFormed(szSaveToPath);
//do things
}
}
