应用程序中的服务器localhost：3000需要用户名和密码(The server localhost:3000 at Application requires a username and password)

 我发现你可以show | hide 使用$.mobile.loading()函数show | hide 加载器 ，这样： 
 
 以显示： 
 
$.mobile.loading( 'show', {
    text: 'Verificando Datos',
    textVisible: true,
    theme: 'z',
    html: ""
});
 
 隐藏： 
 
$.mobile.loading('hide');
 
 至于为什么要渲染加载器，我所做的是使用jQuery CDN，但我只使用脚本而不是CSS引用，所以当时发生的是“加载”显示在页面底部，如我添加CSS引用后，这个加载器就消失了。 仅在一个页面中 （这发生在我的两个页面中） 。 我不想包含CSS引用的原因是因为设计被覆盖而我不想要这个。 
 
 另一页的问题，我只通过添加一些CSS来解决它： .ui-loader{display: none} 
 
 希望有人可以添加这个答案，但目前我认为它解决了我的问题。 

I found that you can show | hide the loader using the $.mobile.loading() function so: 
 
To show: 
 
$.mobile.loading( 'show', {
    text: 'Verificando Datos',
    textVisible: true,
    theme: 'z',
    html: ""
});
 
To hide: 
 
$.mobile.loading('hide');
 
As to why the loader is being rendered, what I did was to use jQuery CDN but I only used the script and not the CSS reference, so what then happened was that the "loading" was being displayed at the bottom of the page, as soon as I added the CSS reference this loader went away. In one page only (this was happening in two of my pages). The reason I didn't want to include the CSS reference was because the design was being overriden and I didn't want this.
 
The other page's problem, I solved it by ONLY adding some CSS: .ui-loader{display: none}
 
Hopefully someone can add to this answer, but for the moment I believe it solves my issues.
