html - Move table rows up and down - Jquery/Javascript -

-

can please tell me how move table rows , down through jquery/javascript.

i have table , each row radio button there in first td. onclicking up/down arrows selected rows should move up/down.

looking forward ideas...

first selected row:

var radio; // assuming there's 1 form in page, replace 0 whatever // , inputs have name 'radiogroupname' (var in document.forms[0].radiogroupname) {     if (documents.forms[0].radiogroupname[i].checked) {         radio = documents.forms[0].radiogroupname[i].parentnode.parentnode;         break;     } }

to shift up:

var prev = radio.previoussibling; var par = radio.parentnode; if (prev) {     par.removechild(radio);     par.insertbefore(radio, prev); }

to shift down:

var next = radio.nextsibling; var par = radio.parentnode; par.removechild(radio); if (next.nextsibling)     par.insertbefore(radio, next.nextsibling); else     par.appendchild(radio);
