Question

面对一个奇怪的问题，worklight适配器无法从模拟器调用。 LogCat给出了以下错误

07-02 20:56:59.063: D/DroidGap(873): onMessage(onNativeReady,null)
07-02 20:56:59.063: D/DroidGap(873): onMessage(onPageFinished,file:///data/data/com.PivMobileNew/files/www/default/PivMobileNew.html#clientListPage)

然而，从普通调用适配器时，它可以正常工作。

这里是适配器调用代码...

function GetClient(strClientName) {
    var invocationData = {
            adapter : 'PivMobileAdapter'
                ,procedure : 'getClient'
                    ,parameters: [{"ClientName":strClientName}]
    };
    WL.Logger.debug(" --------- entered in function GetClient-------    2c");
    try {
    WL.Client.invokeProcedure(invocationData, {
        onSuccess : handleSuccess,
        onFailure : handleFailure,
    });
    }
    catch (e)
    {   WL.Logger.debug("---inside try catch, error occured while invokingProcedure----");
        WL.Logger.debug(e.message);
    }

    function handleSuccess(result) {
        WL.Logger.debug(" --------- inside handling success invoking procedure $('#searchNew').click(function() -------    2c");
        ...some code here1...
        ...some code here2...
    }

    function handleFailure(result) {
        WL.Logger.debug(" --------- inside handling failure invoking procedure $('#searchNew').click(function() -------    2c");
        ...some code here1...
        ...some code here2...
    }
}

不确定如何前进，任何人都可以帮忙吗？

在使用引用之前，必须定义onSuccess和onFailure处理函数。您还需要在变量中保存函数引用，因为您的代码已在函数内部。

var handleSuccess = function(xxx) {
    // some code
};

var handleFailure = function(xxx) {
    // some code
};
// references need to exist prior to passing them as callback handlers.
WL.Client.invokeProcedure(invocationData, {
        onSuccess : handleSuccess,
        onFailure : handleFailure,
});
