Chapter 10

1. The attributes are: id, title, lang, dir, and className

2. Here’s the element type:

3. var elems = document.getElementByName('elemName');
   for (var i = 0; i < elems.length; i++) {
       alert(elems[i].tagName);
   }

4. Here are the element types:

5. var children = nd.childNodes;
   for (var i = 0; i < children.length; i++) {
       alert(children[i].nodeType);
   }
   
   divs = document.getElementsByTagName('div');
    for (var i = 0; i < divs.length; i++) {
        alert(divs[i].id);
   }
   
   var elem = document.getElementById("elem1");
   var children = elem.childNodes;
   var child = elem.getElementsByTagName('h1')[0];
   var p = document.createElement("p");
   var txt = document.createTextNode("hello");
   p.appendChild(txt);
   
   elem.replaceChild(p,child);

6. The solution is:

7. divs = document.getElementsByTagName('div');
    for (var i = 0; i < divs.length; i++) {
        alert(divs[i].id);
   }

8. The solution is:

9. var elem = document.getElementById("elem1");
   var children = elem.childNodes;
   var child = elem.getElementsByTagName('h1')[0];
   var p = document.createElement("p");
   var txt = document.createTextNode("hello");
   p.appendChild(txt);
   
   elem.replaceChild(p,child);
