Question

我目前正按以下方式发送回调

var submitCommunicateCard = function () {
    //display Loading indicator to user
    console.log(rpc.views.Contact.CommunicateCard.getValues());
    Ext.Ajax.request({
        url: WebService('GetInTouch', 'CommunicateCard'),
        method: 'post',
        params: {
            callback: 'foo', // THIS SUCKS!!!
            name: 'Test Name'  
        }
    });
};

虽然这样可行，但我更愿意让Sencha为我添加回调。

我尝试了这个，咬了无效

var submitCommunicateCard = function () {
    //display Loading indicator to user
    console.log(rpc.views.Contact.CommunicateCard.getValues());
    Ext.Ajax.request({
        url: WebService('GetInTouch', 'CommunicateCard'),
        method: 'post',
        scriptTag: true,  //WHY DOESN'T THIS WORK?
        params: {
            name: 'Test Name'  
        }
    });
};

如何正确地向Sencha Touch Ext.Ajax.request（）添加“回调”？

Answer 1

Ext.Ajax生成两种类型的请求后事件，即requestcomplete和requestexception。您可以Ext.Ajax.on("requestcomplete", function (conn, response, options))用于成功请求，Ext.Ajax.on("requestexception", function (conn, response, options))用于失败请求。

答案是“你不能”

您必须使用Ext.util.JSONP.request();

如何在Sencha Touch Ext.Ajax.request（）中正确添加“回调”参数？
