object - Javascript - get number of elements in Document Fragment -


i'm creating counter passing number following function:

function numbertohtml(n) {             function createspan(n) {                 var span = document.createelement('span');                 span.textcontent = n;                 return span;             }             function iter(n, container) {                 if (n === '') return container;                 container.insertbefore(createspan(n.slice(-3)), container.firstchild);                 return iter(n.slice(0,-3), container);             }             return iter(string(n), document.createdocumentfragment());         }

this returns:

documentfragment [ <span>, <span> ]

i'm havibng trouble number of elements in documentfragment. tried $(myobject).length, returns 1.

how can no of items in documentfragment?

sorry first answer wasn't correct. had trouble figuring out, how got outcome (that have been helpfull). looking is:

var myobject = numbertohtml(3231123123); var length = $(myobject).children().length; alert(length); // 4

or juhana pointed out, can omit jquery wrapper:

var myobject = numbertohtml(3231123123); var length = myobject.children.length; alert(length); // 4

since span elements added children, want count children of container.
