Ext弹出新页面

[andy1217]

operationHelpbill:function(){
    	urls = this.baseUrl;
    	var node=this.id.substr(4);
    	Ext.Ajax.request({
	          url: urls+"?cmd=operationHelpbill&pdfName="+node,
	          method: "POST",
	          timeOut: 25000,

	          	if(r.success){
	          	   //这里应该怎么写？
	          	}else{
	          		 Ext.MessageBox.alert("提示信息","说明不存在!"); 
	          	}
	          }
	      });
    },

public void operationHelpbill(String fileName) throws Exception {
		String path = ConfigHelper.findValueByKey("common/System.properties","upload.imgServer")
			+ ConfigHelper.findValueByKey("common/System.properties","upload.img.root")
			+ ConfigHelper.findValueByKey("common/System.properties","upload.pdf.fengkong");
		String comm ="{success:false}";
		String url = path + "/"+ fileName + ".pdf";
		//这里应该怎么把URL传到页面呢？
	}

我想通过页面上点击按钮打开一个新页面通过浏览器查看PDF文件，上面个是按钮的function,下面个是调用的后台方法

[andy1217]

//获得AJAX返回的url
var urls=Ext.util.JSON.decode(response.responseText).url;     //你这里获取后没看明白你是怎么用的？
//将url传递给函数
operationHelpbill:function(urls){
        urls = this.baseUrl;
        var node=this.id.substr(4);
        Ext.Ajax.request({
              url: urls+"?cmd=operationHelpbill&pdfName="+node,     //这里是按钮的ACTION请求
              method: "POST",
              timeOut: 25000,
              async: false,
              success: function(response, opts)
              {
                  var r = Ext.util.JSON.decode(response.responseText);
                  if(r.success){
                     //这里应该怎么写？
    var s1 = new Ext.data.Store({
        reader: new Ext.data.JsonReader({}, [{ name: "Id" }, { name: "name"}]),
        data: [{ id: "1", name: "name1"}]
    });
    var g1 = new Ext.grid.GridPanel({
        store:s1,border: false, loadMask: { msg: "正在加载..." }, viewConfig: { forceFit: true },
        columns: [{ header: "姓名", dataIndex: "name", sortable: true}]
    });
    var win = new Ext.Window({
        title: "查询", width: 500, height: 350, constrain: true, layout: "fit",items:g1
    });
    win.show();
                  }else{
                       Ext.MessageBox.alert("提示信息","说明不存在!"); 
                  }
              }
          });
    },

后台先Response.Write(@"{url :'" + url + "'}");

[andy1217]

你在function里是怎么用这个url的？

[豆虫]

楼主的意思是 想点击按钮 在弹出的Ext window中呈现pdf文档 是这样么

[班门弄斧]

后台得到URL准备传到前台

public void operationHelpbill(String fileName) throws Exception {
        String path = ConfigHelper.findValueByKey("common/System.properties","upload.imgServer")
            + ConfigHelper.findValueByKey("common/System.properties","upload.img.root")
            + ConfigHelper.findValueByKey("common/System.properties","upload.pdf.fengkong");
        String comm ="{success:false}";
        String url = path + "/"+ fileName + ".pdf";
        //这里应该怎么把URL传到页面呢？
         Response.Write(@"{url :'" + url  + "'}");
    }

接收后台返回的response.responseText，从而得到当中的url

//获得AJAX返回的url
var urls=Ext.util.JSON.decode(response.responseText).url;
//将url传递给函数
operationHelpbill:function(urls){
        urls = this.baseUrl;
        var node=this.id.substr(4);
        Ext.Ajax.request({
              url: urls+"?cmd=operationHelpbill&pdfName="+node,
              method: "POST",
              timeOut: 25000,
              async: false,
              success: function(response, opts)
              {
                  var r = Ext.util.JSON.decode(response.responseText);
                  if(r.success){
                     //这里应该怎么写？
    var s1 = new Ext.data.Store({
        reader: new Ext.data.JsonReader({}, [{ name: "Id" }, { name: "name"}]),
        data: [{ id: "1", name: "name1"}]
    });
    var g1 = new Ext.grid.GridPanel({
        store:s1,border: false, loadMask: { msg: "正在加载..." }, viewConfig: { forceFit: true },
        columns: [{ header: "姓名", dataIndex: "name", sortable: true}]
    });
    var win = new Ext.Window({
        title: "查询", width: 500, height: 350, constrain: true, layout: "fit",items:g1
    });
    win.show();
                  }else{
                       Ext.MessageBox.alert("提示信息","说明不存在!"); 
                  }
              }
          });
    },

/套餐操作工具栏
var bar2 = new Ext.Toolbar({
items: [

{
text: '管理图片',
iconCls: 'update',
handler: function () { ProductTabPanel(2); }
}, {
text: "打开详情页面",
iconCls: "connect",
handler: function () {
var row = Ext.getCmp("ProductGrid").getSelectionModel().getSelections();
if (row.length <= 0) {
Ext.Msg.alert("提示信息", "请选择一个!");
}
else if (row.length > 1) {
Ext.Msg.alert("提示信息", "只能选择一个!");
}
// window.open("/Gplugin/ShopProducts/ProductPro.aspx?id=" + row[0].data.Productid);
window.open("/ShopProducts/ProductPro/" + row[0].data.Productid + ".html");
}
}, {
text: '导出Execl',
iconCls: 'ShowExecl',
handler: function () {
//操作Execl导出
var value = Ext.getCmp("SearchCom").getValue();
var key = Ext.getCmp("SearchKey").getValue();
var isshow = Ext.getCmp("ShowCom").getValue();
key = escape(key);
value = escape(value);
window.open("/Gplugin/CMS/ExeclList/ProExecl.aspx?key=" + key + "&value=" + value + "&isshow=" + isshow);

}
}


window.open直接跳转的行不

[andy1217]

对，楼上的说对老

[andy1217]

window.open(url);
直接这样就能达到我要的效果，谢谢各位
