안녕하세요. 많은 도움 부탁드립니다.
제가 다음의 javascript 코드를 IE7에서 실행했는데 문제가 생겼습니다.
function test() {
// These first two lines get the DOM tree for the current Web page,
// and then the <html> element for that DOM tree
var myDocument = document;
var htmlElement = myDocument.documentElement;
// What's the name of the <html> element? "html"
alert("The root element of the page is " + htmlElement.nodeName);
// Look for the <head> element
var headElement = htmlElement.getElementsByTagName("head")[0];
if (headElement != null) {
alert("We found the head element, named " + headElement.nodeName);
// Print out the title of the page
var titleElement = headElement.getElementsByTagName("title")[0];
if (titleElement != null) {
// The text will be the first child node of the <title> element
var titleText = titleElement.firstChild;
//alert(titleText);
// We can get the text of the text node with nodeValue
alert("The page title is '" + titleText.nodeValue + "'");
}
// After <head> is <body>
var bodyElement = headElement.nextSibling;
while (bodyElement.nodeName.toLowerCase() != "body") {
bodyElement = bodyElement.nextSibling;
}
// We found the <body> element...
// Remove all the top-level ![]()
elements in the body
if (bodyElement.hasChildNodes()) {
for (i=0; i<bodyElement.childNodes.length; i++) {</p>
var currentNode = bodyElement.childNodes;
if (currentNode.nodeName.toLowerCase() == "img") {
bodyElement.removeChild(currentNode);
}
}
}
}
}
제 보기에는 titleText.nodeValue 에 홈페이지의 타이틀이 나와야 할것 같은데 도대체 답이 나오지 않습니다.
원인 좀 설명해 주세요.
