In the pop-up window, do not center the display ?, Center display in the pop-up window

Preface: Is the displayed dialog box not centered? Have you used the standard center algorithm or the display is not centered? Where is TM? In the previous article, I introduced the jquery weebox summary. weebox is definitely a good choice in the pop-up box. Now this is a wonderful problem, that is, it is not centered.

Effect

Note: do not care about the display of this page.

Pop-up method 
<Div class = "blank"> </div> <div class = "dlmain" style = "overflow: hidden; width: pixel; "> <div class =" f_l dlr "style =" height: 350px; width: 554px; "> <div class =" dlr1 "> <span class =" f_l "> User Logon </span> <span class =" f_r "style =" font-size: 14px; color: # 8c8c8c; line-height: 14px; margin-top: 16px; "> no account yet? <A href = "" style = "color: # 0196db; "> register </a> </span> </div> <div class =" blank0 "> </div> <form id =" user_login_form "name =" user_login_form "action = "$ {ctx}/login"> <div class = "control-group"> <label class = "control-label"> account </label> <div class =" control-text "> <div class =" pr f_l "> <input type =" text "name =" username "id =" username "value =" "class =" textbox" /> <span class = "holder_tip"> enter the member account </span> </div> </ Div> <div class = "blank0"> </div> <div class = "control-group"> <label class = "control-label"> password </label> <div class = "control-text"> <div class = "pr f_l"> <input type = "password" name = "password" id = "password" value = "" class = "textbox"/> <span class = "holder_tip"> enter the logon password </span> </div> <a href = "" style = "color: # 1184df; font-size: 13px; "> forgot password? </A> </div> <div class = "blank0"> </div> <div class = "blank0"> </div> <div class = "control-group tl"> <label class = "control-label"> </label> <label class = "ui_checkbox" rel = "carry_type"> <input type = "checkbox ""value =" 1 "name =" auto_login "checked =" checked "/> remember me (next automatic login) </label> </div> <div class = "blank0"> </div> <div class = "control-group"> <label class = "title control-label"> </label> <input type = "button" value = "login" name = "submit_form" class = "ui-button theme_bgcolor" id = "btn_do_login" onclick = "do_login_user (); "/> </div> </form> </div> <div class =" blank "> </div>

This page is very bad.

Then let's see how to call her!

Function show_pop_login () {$. weeboxs. open (common. ctx + "/pages/login. jsp? Ctl = ajax & act = login ", {boxid: 'pop _ user_login ', contentType: 'ajax', showButton: false, showCancel: false, showOk: false, title: 'Member login ', width: 700, type: 'wee'}); // $. showErr ("aaaaaaaaaa ");}

You can directly put the page path in the open method.

Then let's look at the center display algorithm:

this.setCenterPosition = function() {            var wnd = $(window), doc = $(document),                pTop = doc.scrollTop(), pLeft = doc.scrollLeft(),                minTop = pTop;              pTop += (wnd.height() - self.dh.height()) / 2;            pTop = Math.max(pTop, minTop);            pLeft += (wnd.width() - self.dh.width()) / 2;            self.dh.css({top: pTop, left: pLeft});        }

You think this is not centered. Why?

So far, you still don't tell me the answer. When I used firebug to debug this code string, I found wnd. height () has more than 1400, and my screen is not so big at most, that is, more than 900.

Y. It's off duty. I don't want to talk about it anymore.

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

If it is

In this way, the obtained height is problematic.

Then you need to place

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
