javascript - How can I pass the row id from a table with a button -


i have table want add button each row , edit row in form. need pass linenumber getjson request. how can that? here table , getjson. (edit)i noticed i'm asking linenumber want id of button pushed '+value.linenumber+'.

//table goes though loop. table_obj.append($('<tr><td>'+value.sln+'</td><td  >'+value.type+'</td><td     > '+value.stopnumber+'</td><td>'+value.loname+'</td><td >'+value.referenceno+'</td> <td class="hide" >'+value.typeid+'</td><td class="hide" >'+value.locationid+'</td> <td class="hide" >'+value.linenumber+'</td><td><button id='+value.linenumber+' onclick=edit()>edit</button></td></tr>'));  //getjson <script> function edit() $.getjson("editstops.php",{ linenumber:$('#linenumber').val() },stophandler) var stophandler = function(data){ $("#slns").val(data[0].value.loadnumber); $("#type").val(data[0].value.type);     $("#stopnumber").val(data[0].value.stopnumber); $("#loname").val(data[0].value.loname); $("#referenceno").val(data[0].value.referenceno);    $("#typeid").val(data[0].value.typeid); $("#locationid").val(data[0].value.locationid);     $("#linenumber").val(data[0].value.linenumber); };  </script>

in button tag, have line number specified id attribute. can pass edit() function argument:

<button id='+value.linenumber+' onclick="edit('+value.linenumber+')">edit</button></td></tr>

then edit function can accept argument , use it:

function edit(linenumber) {     $.getjson("editstops.php",{ linenumber: linenumber }, stophandler); }

note if buttons inside form tag might need add return false; after calling edit() prevent submitting form , refreshing page.

simple working example: http://jsbin.com/okesom/2/edit

alternatively leave off onclick event in button tag entirely. after loop done , table built, attach event buttons this:

$("button").click(function() {     var linenumber = $(this).attr('id');     $.getjson("editstops.php",{ linenumber: linenumber }, stophandler); });

here quick example of second option: http://jsbin.com/ibokon/2/edit

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).

javascript - Clean way to programmatically use CSS transitions from JS? -

as title implies, there proper way set initial css properties (or class) , tell browser transition these value? for example ( fiddle ): var el = document.queryselector('div'), st = el.style; st.opacity = 0; st.transition = 'opacity 2s'; st.opacity = 1; this not animate opacity of element in chrome 29/firefox 23. because ( source ): [...] you’ll find if apply both sets of properties, 1 after other, browser tries optimize property changes, ignoring initial properties , preventing transition. behind scenes, browsers batch property changes before painting which, while speeding rendering, can have adverse affects. the solution force redraw between applying 2 sets of properties. simple method of doing accessing dom element’s offsetheight property [...] in fact, hack work in current chrome/firefox versions. updated code ( fiddle - click run after opening fiddle run animation again): var el = document.queryselector('div'...
