js模拟登陆

举个例子：

$(window).load(function() {

// 动画循环显示介绍图片
var showImg = function(iIndex) {
var strUrl = $("img.present").attr("url");
var aryUrl = strUrl.split(",");
var strSrc = $("img.present").attr("parent_src");
var strImgSrc = strSrc + "/" + aryUrl[iIndex];
$("img.present").attr("src", strImgSrc);
$("img.present").fadeIn(500, function() {
$("img.present").fadeTo(8000, 1, function() {
$("img.present").fadeOut(500, function() {
iIndex++;
if (iIndex >= aryUrl.length) {
iIndex = 0;
}
showImg(iIndex);
});
});
});
};
showImg(0);

// 是否记住用户名
var strIsRemember = getCookie("customer_isRemember");
if (strIsRemember == "true") {
// 设置上次登录的密码
var strUserName = getCookie("customer_UserName");
$("input[name=userName]").val(strUserName);
$("input[name=isRememberUserName]").attr("checked", true);
} else {
$("input[name=userName]").val("");
$("input[name=isRememberUserName]").attr("checked", false);
}

});

// 表单提交时运行
var fnSubmit = function() {
fnRememberUserName();
return true;
};

// 记住用户
var fnRememberUserName = function() {
var isRemember = $("input[name=isRememberUserName]:checked").val();
if (isRemember == "1") {
var strUserName = $("input[name=userName]").val();
setCookie("customer_UserName", strUserName);
setCookie("customer_isRemember", "true");
} else {
setCookie("customer_UserName", "");
setCookie("customer_isRemember", "false");
}
};

// 刷新安全验证码
var fnRefreshVerifyCode = function() {
var oImage = $("img.verifyCode.img126534893467");
oImage.attr("src", oImage.attr("url") + "&" + (new Date()));
};
