One of these things happened today,
Copy Code code as follows:
var frmheight = 352;
var frmwidth = 508;
var frmtop = (window.screen.height-frmheight)/2;
var frmleft = (WINDOW.SCREEN.WIDTH-FRMWIDTH/2);
var url = "Choseperson.aspx";
var parameter = "Dialogheight:" + frmheight + "Px;dialogwidth:" + frmwidth + "Px;dialogtop" + frmtop + "Px;dialogleft" + F Rmleft + "px;scroll:0;status:0;reziable:1;";
var rval = window.showmodaldialog (URL, "", parameter);
window.showModalDialog ()//first load is to walk Page_Load () method, the second load will not go Page_Load ();
Specific reasons:
Is the problem of caching, the first time you open the window, the second browser did not fetch data from the server, and directly found the file you have downloaded,
Final Solution:
1. Set browser properties
Change the settings of IE to try again, Internet Options-> General-> Settings-> Check every time you visit this page
(The advantages of total station reload, to solve the problem)
2. Add the cache to clear the previous cache
Add cache, clear previous data, prevent not loading page
<%@ OutputCache duration= "1" varybyparam= "None"%>
(The advantages are only for the required interface Plus, save time)
New
3. (7/10 test found IE7 does not support the 2nd cache format) No way. Only modify the purge cache code
