最终的问题的错误的使用了预加载，同这个问题：http://ask.dcloud.net.cn/question/20897

这是main页面
//创建子页面，首个1. 选项卡页面显示，其它均隐藏；
$.plusReady(function() {
var self = plus.webview.currentWebview();

                for (var i = 0; i < 1; i++) {  
                    var temp = {};  
                    var sub = plus.webview.create(subpages[i], subpages[i], subpage_style);  
                    if (i > 0) {  
                        sub.hide();  
                    } else {  
                        temp[subpages[i]] = "true";  
                        $.extend(aniShow, temp);  
                    }  
                    self.append(sub);  
                }  
            });

子页面中
if ($.os.plus) {
$.plusReady(function() {
setTimeout(function() {
$('#pullrefresh').pullRefresh().pullupLoading();
}, 1000);
});
} else {
$.ready(function() {
$('#pullrefresh').pullRefresh().pullupLoading();
});
}

子页面list页面就是上啦加载，main页面有选项卡，list为首选项卡，可是第一次进来的时候数据不能初始化，不论写在哪都不行。

参考tab-webview-main.html和tab-webview-subpage-chat.html页面

回复赵梦欢:我就是这么写的关键是我的数据是服务端获取的初始化的时候是脚本动态加载的，现在就是初次加载父页面，子页面数据根本加载不出来

回复 k***@126.com:首先排查ajax能够取到数据吗？建议打个测试工程。

回复 k***@126.com:另外是不是经过了预加载，建议看看这个问题：http://ask.dcloud.net.cn/question/20897

回复赵梦欢:嗯就是预加载问题，看了这篇文章帮助很大。谢谢！！

我觉得直接按这样写应该没有问题吧
