php - What is a cleaner / better way of parsing data received by an ajax success function? -

-

i using ajax function receive data. based on data, if results not found receive string "no matches found" html formatting. if there results, data formatted table , "div" section underneath section hidden.

now issue having is, when find no results, not want "div" table disappear.but check if there no results, have compare whole string received searchcustomer.php (which large).

is there easier way of doing this?

my ajax call:

$('#search').click(function(e){         $.ajax({             type : 'get',             url : 'searchcustomer.php',             datatype :'html',             data:{                 lastname : $('#search_ln').val(),                 firstname : $('#search_fn').val(),                 phone : $('#search_pn').val()             },             success : function(data){                 if (data.error == true){                     alert("there error in post layer");                 } else {                     $('#searchresults').html(data);                    if (data.text == '<br><font color='red'>no matches found</font>'){                 }else{                 var ele = document.getelementbyid("newcustomerdiv");                 ele.style.display = "none";                 }             }         }     });     return false; });

running fire-bug, actual data received searchcustomer.php is:

<style type="text/css"> a.resultbookbutton {     color: black;     padding: 1px;     border: 2px outset lightgrey;      background: #008800;     /* mozilla: */     background: -moz-linear-gradient(top, lightgrey, #ffffff);     /* chrome, safari:*/     background: -webkit-gradient(linear,                 left top, left bottom, from(lightgrey), to(#ffffff));      text-decoration: none; }  a:active {     border-style: inset; } </style>  <br><font color='red'>no matches found</font>

i want check "no matches found" or if there better way of finding no results.

i disagree brad, converting json pain because html uses quotes time have have quotes escaped in order work in json string, can present annoyance @ best , accidentally trigger errors invalid json @ worst.

the ideal solution changing pages return. return full html if items found, return "0" or "" if nothing found, , check returns.

if can't change returned ajax call, perhaps (returneddata.indexof("

easy peasy.

edit:

$.ajax({       ... other setting ...         success : function(data){            (data.indexof('<table') == -1){                 //there table in returned data            } else {                 // ...            }         }       });

php - What is the difference between $_SERVER['PATH_INFO'] and $_SERVER['ORIG_PATH_INFO']? -

what’s difference between $_server['path_info'] , $_server['orig_path_info'] ? how use them? when run print_r($_server) , path_info , orig_path_info not present in array. why not? how can enable them? i have read php manual on them, still don’t understand them. the path_info variable present if invoke php script this: http://www.example.com/phpinfo.php/hello_there it's /hello_there part after .php script. if don't invoke url that, there won't $_server["path_info"] environment variable. the porig_ prefix uncommon. path_info standard cgi-environment variable, , should never prefixed. did read that? (there issues around php3/php4 if invoked php interpreter via cgi-bin/ - hardly has such setups today.) for reference: http://www.ietf.org/rfc/rfc3875

i'm attempting recode old c++ program in fortran make use of lapack (i'm aware c++ have lapack++, i'm having lot of trouble installing it, gave up). i didn't have problems compilation, when had variables declared real . when started coding section of program required lapack, found parameters passed dsyev need double precision . tried change double precision (including changing hard coded numbers double precision counterparts, i.e. 0.0 -> 0.0d0) when try compile, following error of functions , subroutines i've written: error: return type mismatch of function <function> @ (1) (real(4)/real(8)) i'm not sure coming from, in program has been changed double precision. for example, i've declared following: double precision :: alpha(3),d(3),zeta1,zeta2 double precision :: a1(3),a2(3),d1(3),d2(3) double precision :: pi pi = 3.14159265359d0 alpha = (/0.109818d0, 0.405771d0, 2.22766d0/) d = (/0.444635d0, 0.535328d0, 0.154329d0 /) 10 i=1,3 ...

queue - mq_receive: message too long -

-
i implementing communication between 2 processes using queue. problem when call function mq_receive, error: message long. i have done following: struct mq_attr attr; long size = attr.mq_msgsize; .... // initializing queue "/gateway" int rc = mq_receive(gateway, buffer, size, &prio); if print size value, size=1, while when print same size program (got same mechanism), not long integer ( -1217186280 )... how can solve error?....so while size = 1, believe it's right "message long" why 1? p.s. have tried put : int rc = mq_receive(gateway, buffer, sizeof(buffer), &prio); but no result. it seems need read docs more carefully. when call mq_receive should pass size of destination buffer. this size must greater mq_msgsize attribute of queue . in addition, seems have error in queue attributes initialisation makes proper mq_receive call impossible. here standard message queue session: fill mq_attr struct ( doc ): struct mq_a...
