web方式选择文件保存路径的两种解决方案解决方案1:
调用windows 的shell,但会有安全问题.
browserFolder.js:
/**//***
path 要显示值的对象id
****/
function browseFolder(path) {
try {
var Message = "\u8bf7\u9009\u62e9\u6587\u4ef6\u5939"; //选择框提示信息
var Shell = new ActiveXObject("Shell.Application");
var Folder = Shell.BrowseForFolder(0, Message, 64, 17);//起始目录为：我的电脑
//var Folder = Shell.BrowseForFolder(0,Message,0); //起始目录为：桌面
if (Folder != null) {
Folder = Folder.items(); // 返回 FolderItems 对象
Folder = Folder.item(); // 返回 Folderitem 对象
Folder = Folder.Path; // 返回路径
if (Folder.charAt(Folder.length - 1) != "\\") {
Folder = Folder + "\\";
}
document.getElementById(path).value = Folder;
return Folder;
}
}
catch (e) {
alert(e.message);
}
}
使用的时候:
<td> <input type="text" name="path" /> </td>
<td> <input type="button" onclick="browseFolder('path')" value="选择生成路径" /> </td>
2.解决方案二:
自己写一个js读取本地硬盘的选择框, 缺点是外观上较上一个差一些. <html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title>无标题文档</title>
</head>
<body>
<table border="0" cellpadding="0" width="100%" id="tb_show">
<tr>
<td width="18%">文件保存位置:</td>
<td width="82%">
<%--<html:file property="file" size="40" styleClass="inputbox"/>--%>
<input name="backDir" type="text" value ="C:\" size="100" width="500">
</td>
</tr>
<tr>
<td>目录位置:</td>
<td>
<select name="tables_drive" id="tables_drives" onchange="get_drives()" ></select>
</td>
</tr>
<tr>
<td colspan="2">
<select name="table_folder" id="table_folder" size="10" multiple ondblclick="get_file()"></select>
</td>
</tr>
</table>
