javascript - Giving ID to dynamically created button in jQuery -

-

i'm trying create set of buttons using jquery , give them id's, when try reference id's later, doesn't seem work. can fix it?

for(i=0;i<7;i++) {     $("h2")     .append('<input type="button" value="display answer">')     .button()     .attr("id", i); };   $("button").click(function() {     if($(this).attr("id") === "all") {         for(i=0;i<answerarr.length+1;i++){             $("#p" + i).text(answerarr[i-1]);         }     } else {         $("#p" + $(this).attr("id")).text(answerarr[$(this).attr("id")-1]);     }   });

.append() returns element called on, not newly appended element. adding id (and calling .button()) on <h2> element(s).

try using .appendto() instead, , adding id when create element:

$('<input/>', {     type: 'button',     id: i,     value: 'display answer' }).appendto('h2').button();

i used pyinstaller create standalone exe file pyqt project. did not use single file option because exe created single file option takes long open. therefore, pyinstaller created dist folder contains bunch of files including program.exe file. create setup.exe file place contents of dist folder in program directory , create shortcut in start menu , on desktop. want super simple user. maybe setup.exe files when download program cnet. found inno-setup, looks promising. however, not know if there special considerations because program standalone program create python/pyqt program. thanks! have experience task? there program using task not know about? inno-setup or nsis easiest use. tell them files include , put them , create nice installer you. wrote short tutorial on experiences using innosetup might find helpful: http://www.blog.pythonlibrary.org/2008/08/27/packaging-wxpymail-for-distribution/ note tutorial based around wxpython app wrote, concepts same.
