订阅activatedRoute，params具有不同的属性来保存传递的参数值(subscribing to activatedRoute, params has different attributes to hold the param value passed)

 您可以使用pagecontainer小部件的beforeshow事件： http ：//api.jquerymobile.com/pagecontainer/#event-beforeshow 
 
 ui参数的toPage属性返回您要导航到的页面的jQuery对象。 然后，您可以检查其ID并显示正确的文本。 
 
$(document).on( "pagecontainerbeforeshow", function( event, ui ) {
    var pageid = ui.toPage.prop("id");

    if(pageid == 'frontPage') { 
        setTitle('Front Page', ui.toPage); 
    } else if (pageid == 'pageB') {
        setTitle('Page B', ui.toPage); 
    } else if(pageid == 'pageC') { 
        setTitle('Page C', ui.toPage); 
    }

});

function setTitle(text, page){
    page.find(".headerText").text(text);
}

 每次导航到页面时都会运行，这样您每次都可以显示不同的标题。 如果您只显示相同的标题，则可以使用pagecreate事件，因为它只在每个页面最初加载到DOM时运行一次： 
 
$(document).on( "pagecreate", function( e ) {    
    var pageid = e.target.id;    

    if (pageid == 'frontPage') { 
        setTitle('Front Page', pageid); 
    } else if (pageid == 'pageB') {
        setTitle('Page B', pageid); 
    } else if(pageid == 'pageC') { 
        setTitle('Page C', pageid); 
    }    
});

function setTitle(text, pageid){
    $("#" + pageid).find(".headerText").text(text);
}

You can use the pagecontainer widget's beforeshow event: http://api.jquerymobile.com/pagecontainer/#event-beforeshow
 
The toPage property of the ui parameter returns a jQuery object of the page you are navigating to. You can then check its ID and display the correct text.
 
$(document).on( "pagecontainerbeforeshow", function( event, ui ) {
    var pageid = ui.toPage.prop("id");

    if(pageid == 'frontPage') { 
        setTitle('Front Page', ui.toPage); 
    } else if (pageid == 'pageB') {
        setTitle('Page B', ui.toPage); 
    } else if(pageid == 'pageC') { 
        setTitle('Page C', ui.toPage); 
    }

});

function setTitle(text, page){
    page.find(".headerText").text(text);
}

This will run every time you navigate to the page so you could show different titles each time. If you only ever show the same title, you could use the pagecreate event instead as it only runs once when each page is initially loaded into the DOM:
 
$(document).on( "pagecreate", function( e ) {    
    var pageid = e.target.id;    

    if (pageid == 'frontPage') { 
        setTitle('Front Page', pageid); 
    } else if (pageid == 'pageB') {
        setTitle('Page B', pageid); 
    } else if(pageid == 'pageC') { 
        setTitle('Page C', pageid); 
    }    
});

function setTitle(text, pageid){
    $("#" + pageid).find(".headerText").text(text);
}
