javascript - What's the best way to get data back from a jqGrid cell? -


i'm new jqgrid , needed data cell editing , wanted avoid accessing server.

since custom formatter adding tags data, , using getcell returns tags well,my first implementation strip off 'manually':

createcolumn: function (val, options) {     return '<div style="white-space:pre-wrap">' // etc.         + val         + '</div>'; } // ... // note: rowid known @ point var mydata = $('#mygrid').jqgrid('getcell',rowid,'mydata'); var mydatawrapper = mydata.createcolumn(''); data = data.substr(mydatawrapper.length-6,data.length-mydatawrapper.length);

of course, break if adds more complex tags. looked @ way getcell finds data. unfortunately, @ present, searches name code is:

var n = -1; val colmodel = $('#mygrid').jqgrid('getgridparam','colmodel'); (var in colmodel) {     if (colmodel[i].name === 'mydata') {     n = parseint(i)+1; } var mydata = $('#'+rowid+' td:nth-child('+n+') div').text();

it seemed wrong duplicate code in getcell, there doesn't seem other way find column number name (at least, couldn't find it!). assumes data wrapped in single div, in first version.

looking @ generated html, noticed jqgrid tags cell using aria-describedby (which i've never seen before). if guaranteed there, above can done using:

var mydata = $('#'+rowid+' td:[aria-describedby=mygrid_mydata] div').text();

but still uses assumption data wrapped in single div and, of course, future version of jqgrid change or remove attribute.

so tried simple solution adding id wrapping data in span find it:

createcolumn: function (val, options) {     return '<div style="white-space:pre-wrap">' // etc.         + '<span id="' + options.gid + '_' + options.rowid + '_' + options.colmodel.name + '">' + val + '</span>'         + '</div>'; } // ... var mydata = $('#mygrid_'+rowid+'_mydata').text();

this seem best way (as have full control on it) there better way data passed formatter function won't break on possible future upgrades jqgrid , doesn't require adding tags?

regarding initial part of question:

since custom formatter adding tags data, , using getcell returns tags well...

the standard way data without tags implement unformat function. jqgrid docs:

as mentioned in predefined formatter chapter predefined types compatible editing modules. means numbers, links, e-mails, etc., converted can edited correctly. methods (like getrowdata , getcell) data, used unformat in order original value. question is: if use custom formatter function , want to have original value if use editing or methods getrowdata , getcell?

the answer is: can use own custom unformatter function that. function can used in colmodel

for example:

jquery("#grid_id").jqgrid({ ...    colmodel: [        ...        {name:'price', index:'price', width:60, align:"center", editable: true,        formatter:imageformat,         unformat:imageunformat},       ...    ] ... });  function imageformat( cellvalue, options, rowobject ){     return '<img src="'+cellvalue+'" />'; }  function imageunformat( cellvalue, options, cell){     return $('img', cell).attr('src'); }

see unformatting section of jqgrid documentation full details, including parameter descriptions.

php - Why I am getting the Error "Commands out of sync; you can't run this command now" -

the documentation of error mentioned in title says if commands out of sync; can't run command now in client code, calling client functions in wrong order. this can happen, example, if using mysql_use_result() , try execute new query before have called mysql_free_result(). can happen if try execute 2 queries return data without calling mysql_use_result() or mysql_store_result() in between. from here: http://dev.mysql.com/doc/refman/5.0/en/commands-out-of-sync.html but in first query not fetching data mysql database, inserting. , in second query getting data database. here code $connection = mysqli_connect("localhost","username","password","tbl_msgs"); if(mysqli_connect_errno($connection)) { die("failed connect mysql: " . mysqli_connect_error()); } $query = "insert users (total_comments, total_views) values ({$total_comments}, {$total_views});"; $query .= "insert msgs (no...

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
