js showModalDialog弹框用法
场景:
我要做一个图片上传,上传成功后,弹出一个页面,填写其他信息.
上传图片的界面:
选择文件之后,点击[上传]按钮,
选择确定之后,图片上传到服务器,同时服务器会返回json字符串,其中有图片路径,此时使用window.showModalDialog,弹出一个网页,网页中要获取图片地址,用于显示图片
父页面关键代码:
var options = {
url: "<%=path%>/upload/upload",
type: "POST",
dataType:‘json‘,
success:function(json) {
// alert(json.fileName);
var obj22 = new Object();
obj22.picPath=json.fileName;
$(‘#picForm‘).resetForm();
window.showModalDialog("<%=path%>/patientPic/add",obj22,"dialogWidth=600px;dialogHeight=640px;help=no");
},
error:function(er){
//functionChange(er.responseText);
}
};
$(‘#picForm‘).ajaxSubmit(options); 其中obj22 是用于把父窗口的值传递给子窗口的.
子窗口代码:
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme() + "://"
+ request.getServerName() + ":" + request.getServerPort()
+ path + "/";
%>

</html>子窗口通过
window.dialogArguments
获取父窗口传递的值,界面如下:
上述图片就是根据父窗口传过来的图片路径来显示的.
