前幾天做了批量上傳圖檔的功能,看似簡單,其實也不簡單,主要還是細節!

文字說明的textbox經過了處理然後支援了工具欄
<script src="../Content/My97DatePicker/WdatePicker.js"></script>
<link href="../Content/kindeditor/themes/qq/qq.css" target="_blank" rel="external nofollow" rel="stylesheet" />
<script src="../Content/kindeditor/kindeditor-all-min.js"></script>
<script charset="utf-8" src="../Content/kindeditor/lang/zh-CN.js"></script>
<script>
var editor1;
KindEditor.ready(function(K) {
editor1 = K.create('#<%=body.ClientID%>', {
uploadJson: '/handler/ke_upload.ashx',
items: [
'source', '|','fontname', 'fontsize', '|', 'forecolor', 'hilitecolor', 'bold', 'italic', 'underline',
'removeformat', '|', 'justifyleft', 'justifycenter', 'justifyright', 'insertorderedlist',
'insertunorderedlist', '|', 'emoticons', 'image', 'multiimage', 'link'],
afterChange: function () {
this.sync();
},
newlineTag: "br"
});
});
</script>
以下是沒有工具欄的頁面代碼

新增按鈕給背景傳位址,然後儲存到資料庫就可以完成一些列的管理.這是頁面上的一些處理如果要在背景管理可以添加一個新的頁面來做背景管理和寫一個ashx檔案來接收ajax然後處理資料..
背景接收到的資料通過string img = context.Server.UrlDecode(context.Request["img"]);
string[] image= img.Split(',');
for (int i = 0; i < image.Length-1; i++)
{
//儲存到資料庫
}
來處理圖檔資訊,然後一張一張的儲存到資料庫就可以了
