html页面中的js代码

实现指定路径目录时出现指定的图片，没有指定路径时为默认图片，以下为代码，有点错误：在前三个路径时默认图片也出来了var href = window.document.location.hrefvar html = ✀✀;var matchDomain = ✀http://www.abc.com/aaa/✀;var domain = href.substr(0, matchDomain.length);if (domain == matchDomain)html = html+✀<div class=尀"divline尀"></div><div class=尀"c_left1尀"><a href=尀"http://www.abc.com尀"><img src=尀"1.gif尀"></a></div>✀;var matchDomain = ✀http://bbs.abc.com/aaa/✀;var domain = href.substr(0, matchDomain.length);if (domain == matchDomain)html = html+✀<div class=尀"divline尀"></div><div class=尀"c_left1尀"><a href=尀"http://www.abc.com尀"><img src=尀"2.gif尀"></a></div>✀;var matchDomain = ✀http://www.abc.com/bbb/✀;var domain = href.substr(0, matchDomain.length);if (domain == matchDomain)html = html+✀<div class=尀"divline尀"></div><div class=尀"c_left1尀"><a href=尀"http://www.abc.com尀"><img src=尀"3.gif尀"></a></div>✀;var matchDomain = ✀http://bbs.abc.com/bbb/✀;var domain = href.substr(0, matchDomain.length);if (domain == matchDomain)html = html+✀<div class=尀"divline尀"></div><div class=尀"c_left1尀"><a href=尀"http://www.abc.com尀"><img src=尀"4.gif尀"></a></div>✀;elsehtml = html+ ✀<div class=尀"divline尀"></div><div class=尀"c_left1尀"><a href=尀"http://www.abc.com尀"><img src=尀"5.jpg 尀"></a></div>✀;document.writeln(html);document.close();

var href = window.document.location.href
var html = '';
var matchDomain = 'http://www.abc.com/aaa/';
var domain = href.substr(0, matchDomain.length);
var isDefault = true;
if (domain == matchDomain) {
html = html+'

';
isDefault = false;
}

var matchDomain = 'http://bbs.abc.com/aaa/';
var domain = href.substr(0, matchDomain.length);
if (domain == matchDomain) {
html = html+'

';
isDefault = false;
}

var matchDomain = 'http://www.abc.com/bbb/';
var domain = href.substr(0, matchDomain.length);
if (domain == matchDomain) {
html = html+'

';
isDefault = false;
}

var matchDomain = 'http://bbs.abc.com/bbb/';
var domain = href.substr(0, matchDomain.length);
if (domain == matchDomain) {
html = html+'

';
isDefault = false;
}

if (isDefault)
html = html+ '

';

document.writeln(html);
document.close();

isDefault为是否是默认的判断变量。
