javascript - How to add an element to another one(instead of using selector) -


i found in document can create element , add 1 like:

var sel = document.createelement("select"); var opt1 = document.createelement("option"); var opt2 = document.createelement("option");  opt1.value = "1"; opt1.text = "option: value 1";  opt2.value = "2"; opt2.text = "option: value 2";  sel.add(opt1, null); sel.add(opt2, null);

but when tried apply practice, method doesn't work, newuser not added newdiv successfully:

function createonele(imgsrc, user, extract) {   var newdiv = document.createelement("div");   var newuser = document.createelement("span");    newuser.textcontent = user;    newdiv.add(newuser);  }

it seems add method doesn't work div , span, if true, how achieve it? otherwise, did wrong?

.add method of select-element used add option-element it.

refer htmlselectelement.add()

use .appendchild()

the node.appendchild() method adds node end of list of children of specified parent node.

function createonele(user) {    var newdiv = document.createelement("div");    var newuser = document.createelement("span");    newuser.textcontent = user;    newdiv.appendchild(newuser);    document.body.appendchild(newdiv);  }  createonele('rogb :)')

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
