parameter passing - How to pass a value from parent to a fancybox 2.1.7 element, afterShow? - 


$.fancybox({   type: 'iframe',   href: url,   aftershow:  function() {     var name = parent.$('#pname').val();     $('#fname').val(name);     $('#fname').focus();     return true;   },   beforeclose: function(){      clscarr();   },

where pname input box in parent document , fname input box in fancybox document. how put value of pname in fname? aftershow knows value of pname, not putting in fname.

i saw iframe in fancybox. it's interesting trying iframes "talk" parent document, i'm not positive i've got 100% right. :)

var name = parent.getelementbyid("lst-ib").value; document.queryselector("#fancybox-content iframe").contentdocument.getelementbyid("fname").value = name;

my thought behind $.fancybox running in parent document, , when use parent.$('#pname').val() equivalent running $('#pname').val(), since parent not able 'higher' root document.

thus, if theory correct, need iframe , access contentdocument (or perhaps document), , fetch id of element inside iframe.

this would, obviously, work if iframe using same domain parent document. believe browsers implement sort of cross-domain verification nowadays.

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);
