The Magical%EF%BB%BF

Don't say much nonsense about the code:
Front desk:

function On_post_form () {var f = document.post_myform;var S_paramname = document.getElementById ("Select_paramname"). value;        F.action = "__app__/index/select_infomessage-s_paramname-" +encodeuricomponent (s_paramname) + ". html";        F.submit ();}

$ (document). Ready (function () {$ (' #select_paramName '). KeyUp () The ID of the function () {///input box is search, which listens for the KeyUp event $.ajax of the input box ({ty PE: "Get",//ajax submit as Get submit URL: "__app__/index/get_search_showdiv",//URL address of processing page data: "S_name=" +encodeuricomponent ($ (' #select_paramName '). Val ()),//The parameter to be passed success:function (data) {//succeeded after executing the method if (Data! = "") {var ss;ss = Data.spl   It ("@"); The split returns the string var Layer;layer = "
 
  < td="">";} Layer + = "
 
 
 
  
  "; Create a tablefor (Var i=0;i
 
 "; $ (' #searchresult '). empty (); First empty all child elements under #searchresult $ (' #searchresult '). append (layer);//Insert the table you just created into #searchresult $ ("#searchresult"). css ("Display", ""); $ ('. Line '). Hover (function () {///listen for the mouse hover event of the cue box $ (this). addclass ("hover");},function () {$ (this). Removeclass ("hover");}); $ ('. Line '). Click (function () {///listen for the mouse-clicks event $ (' #select_paramName '). Val ($ (this). text ()); $ ("#searchresult"). CSS ("  Display "," none ");   Changecoords ();});   }else{$ (' #searchresult '). empty (); }   }  }); });});

Background:

Public Function Get_search_showdiv () {   //urlencode urldecode text box automatically prompts   $keyword = UrlDecode ($_get[' s_name ']);   $condition = "F_hotname like '%". $keyword. " %'";   $info = $this->model->table (' Forest ')->field (' F_hotname ')->where ($condition)->order (' f_id desc ')- >limit (5)->select ();   if ($keyword! = "") {   foreach ($info as $vo)        {       echo $vo [' F_hotname ']. ' @';       }    } else{          echo "";   }}

Problem symptoms: For example, enter "Baidu"
Shown in the DIV #searchresult:
Baidu Antivirus
Baidu Guardian
Baidu Video

If you choose the first Baidu anti-virus, Firefox browser display:
http://192.168.1.101/index/select_infomessage-s_paramName-%EF%BB%BF% Baidu Antivirus. html
There's nothing ...
If you choose the second Baidu Guardian, Firefox browser display:
http://192.168.1.101/index/select_infomessage-s_paramname-Baidu Guardian. html
Normal search, you can search for information. Other items are normal, except the first one is not normal.

Degree Niang said is BOM head, I all pages are to BOM head, coding is UTF8, try a lot also can not solve the problem.
Why do you add%ef%bb%bf% at the first time,,,,, and all other items can be displayed normally?

Reply to discussion (solution)

%EF%BB%BF is not the URL code of the BOM header?
Because there is only one, so your program loads only one of the files that has a BOM header

Public Function Get_search_showdiv ()
The php script file where this function is located has a BOM

%EF%BB%BF is not the URL code of the BOM header?
Because there is only one, so your program loads only one of the files that has a BOM header

Sorry, these days travel, just come back, what mean, didn't see understand.

The hexadecimal representation of the BOM header for the Utf-8 file is EFBBBF
URL encoding is%EF%BB%BF

The URL for the AJAX request is __app__/index/get_search_showdiv
Obviously this is in the use of frames

The framework will load at least 3 files when processing a request
So any file that is loaded has a BOM header, and the returned content will have a BOM header

The connection becomes ....%EF%BB%BF Baidu anti-virus. html
Instead of ....%EF%BB%BF%EF%BB%BF Baidu anti-virus. html
It means that only one file has a BOM header.

Ajax received a string of shapes like xxx@xxx@xxx@.
The BOM is, of course, attached to the front of the content: bomxxx@xxx@xxx@
After splitting into an array, it is natural that only the first item has a BOM.

So how do we solve this problem?
