在jQuery Mobile 1.1中进行繁重的处理之前显示加载微调器吗?

问题描述

限时删除！！

我很生气，试图让一个微调框出现.我将繁重的处理功能绑定到了按钮上:

I'm going mad trying to get a spinner to appear. I've bound my heavy processing function to a button thus:

$(document).delegate("#clearread", "tap", onClearRead);

因此，在点击它时将其称为:

So on tap it calls this:

var onClearRead = function() {

setTimeout($.mobile.showPageLoadingMsg, 5);

// Civilised cleaning of saved status
var jStorIndex = $.jStorage.index();
for (var i = 0; i < jStorIndex.length; i++) {
    if( jStorIndex[i] != "version" ) {
        $.jStorage.deleteKey(jStorIndex[i]);
    }
}

// Load articles afresh
loadArticles();

$.mobile.changePage("#choosearticle");

} //onClearRead

我发现微调程序在文章的清除/加载过程中没有出现(大约10秒)，而只是在#choosearticle页面加载期间(0.5秒)出现了很短的时间.我在做什么错了?

I find that the spinner does not appear during the clearing/loading of articles (about 10 secs) but only for a brief period while the #choosearticle page loads (0.5 secs).What am I doing wrong?

我让微调器在应用程序的其他位置工作.

I have the spinner working elsewhere in the app.

谢谢

推荐答案

尝试一下:

$(document).delegate("#clearread", "tap", onClearRead);

var onClearRead = function() {
$.mobile.showPageLoadingMsg();
setTimeout(function(){
        //Your heavy processing
        $.mobile.changePage("#choosearticle");
    }, 5);
} //onClearRead
