javascript - Sortover and sortout events not triggered after element is replaced -


the middle column should change width when dragging element on it. work until click on replace button replaces html of middle column. events stop being triggered. far know .on() should able handle such cases, or wrong?

this simple demo demonstrates issue: https://jsfiddle.net/shuetvyj/3/

html:

<div class="members-column">   <div class="sort"> 1 </div>   <div class="sort"> 1 </div> </div> <div id="groupb" class="members-column">  </div> <div class="members-column">   <div class="sort"> 2 </div> </div> <a href="" id="replace">replace groupb</a>

javascript:

$(".members-column").sortable({    items: ".sort",    connectwith: ".members-column"      }); $("#groupb").on("sortover", function() {   console.log('overb');   $('#groupb').css('min-width','80px'); }); $("#groupb").on("sortout", function() {   console.log('outb');   $('#groupb').css('min-width',''); }); $("#replace").on("click", function(e) {     e.preventdefault();   $("#groupb").replacewith('<div id="groupb" class="members-column"></div>'); });

when replace html, listeners had attached old html not reattached new html.

as result, handlers no longer called. solve this, attach listeners new html when have replaced it.

(jquery solved while live instead of on, automatically attach listeners after dom changes) http://api.jquery.com/live/

but live() has been deprecated since jquery 1.7 , removed in 1.9

additionally, removing column breaks sortable's behavior (since not store selector result of selector when first called, , retains reference div removed dom.

in short ; not remove column div once have sortable listening it, clear or replace contents

transpose - Maple isnt executing function but prints function term -

im using maple im in worksheetmode tried using maple input , 2d input , want transpose matrix a: := `<|>`(`<,>`(1, .5, -2), `<,>`(.5, 9/4+b, 5+3*b), `<,>`(-2, 5+3*b, 18+9*b+4*a)); b:= transpose(a); when exectute sheet dont translated values, there same input. matrix looks same input matrix plus function term. you can see picture in following link: why arent functions executed? meanwhile b:=a^+ doing right way , transposed matrix. other functions return function body instead needed values... if using 2d input mode (the default) space you've got between transpose , bracketed (b) interpreted multiplcation. rid of such space. also, either load package @ start of document like, with(linearalgebra): before calling transpose command package, or call it's full name like, linearalgebra:-transpose(b);
