mui问题调试

targetView.onloaded提示有错误targetView为空，附代码：
<script type="text/javascript" charset="utf-8">
mui.plusReady(function() {
var rememberMe = plus.storage.getItem("rememberMe");
var token = plus.storage.getItem("token");
var tagetUrl, tagetId;
var targetView = null;
if (rememberMe == '0' || token == null) {
targetView = mui.preload({
url: 'login.html',
id: 'login'
});
} else {
console.log('111');
var userInfo = plus.storage.getItem('userInfo');
var userName = plus.storage.getItem('userName');
var passWord = plus.storage.getItem('passWord');
var orgCode = plus.storage.getItem('orgCode');
var clientId = plus.storage.getItem('clientId');
var url = "app/appLogin.do?usercode=" + userName + "&password=" + passWord + "&orgCode=" + orgCode + "&clientid=" + clientId;
ajaxSubmit(url, ajax_userLogin_success);
}
function ajax_userLogin_success(){
console.log('222');
targetView = mui.preload({
url: 'index.html',
id: 'index'
});
//触发首页的showIndex事件
mui.fire(targetView, 'showIndex', {
userInfo: userInfo
});
}
console.log(targetView);
targetView.onloaded = function(e) {
plus.navigator.closeSplashscreen();
};
targetView.show('pop-in');
});
</script>
