如何在IBM MobileFirst中从一个html页面导航到另一个html页面？

<button onclick="navigateToPage2()">Go to Page 2</button>

function navigateToPage2() {
    WL.App.overrideBackButton(function() {
        WL.App.close();
    });

    WL.SimpleDialog.show(
        "Navigation",
        "Do you want to navigate to Page 2?",
        [
            { text: "Cancel", handler: function() {} },
            { text: "OK", handler: function() { WL.App.openURL("page2.html"); } }
        ]
    );
}

<button onclick="navigateToPage1()">Go back to Page 1</button>

function navigateToPage1() {
    WL.App.overrideBackButton(function() {
        WL.App.close();
    });

    WL.SimpleDialog.show(
        "Navigation",
        "Do you want to go back to Page 1?",
        [
            { text: "Cancel", handler: function() {} },
            { text: "OK", handler: function() { WL.App.close(); } }
        ]
    );
}
