ext开发中中遇到的问题总结

1.描述：在工具栏中输入实验室别名和数据采集范围之后调用另外一个controller。两个不同controller之间调用问题。

当实验室别名和时间改变 的controller中

this.fireEvent('acquisitioncontrollersuccess'+responseText);

在另一个controller中写监听  

listen: {
    controller: {
        'acquisition-controller': {上一个controller的别名。
            acquisitioncontrollersuccess: 'specimenIndexData' 监听要调用的方法。
        }
    }
},

2.加载假的json数据。

specimenIndexData: function (labName,dataAcquisition) {
    var deferred = Ext.create('Ext.Deferred');
    var store = this.getViewModel().getStore('specimenNumber');  得到store。
    var meStore = store;
    store.clearFilter(true);
    var filter = Ext.create('Ext.util.Filter', {
        property: 'labName',
        value: labName
    });
    store.addFilter(filter, true);
    var filter1 = Ext.create('Ext.util.Filter', {
        property: 'dataAcquisition',
        value: Ext.Date.format(dataAcquisition, 'Y-m')
    });
    store.addFilter(filter1, true);
    meStore.proxy.url='./dataacquisition/specimennums';  向后台发送请求 如果小于0 就加载假json
    store.load({
        callback: function (records, operation, success) {
            var responseText = Ext.decode(operation.getResponse().responseText);
            if (!success) {
                Amili.amili.FlyTip.fly(responseText.title, responseText.message, responseText.category);
            }else{
                if (records.length <= 0) {
                    meStore.getProxy();
                    var url = Amili.getApplication().paths['Amili.dataacquisition'] ? './dataacquisition/data/SpecimenIndexData.json' : './webjars/dataacquisition/data/SpecimenIndexData.json';
                    meStore.proxy.url = url;
                    meStore.load();
                }
                deferred.resolve(records);
            }
        },
        scope: this
    });
    return deferred.promise;
}

specimenNumberEdit: function (editor, context, eOpts) {
    var id = this.getViewModel().get("labId"),
        collectTime = this.getViewModel().get("collectDate");
    if (context.record.dirty) {
        if (id === null || id.replace(/\s/g, "").length === 0 || collectTime === null) {
            Amili.amili.FlyTip.fly('警告', '请输入实验室名称或选择数据采集范围', 'warning');
            return;
        }
        var records = context.store.getData();
        if (records.length > 0) {
            var list = [];
            for (var i = 0; i < records.length; i++) {
                var newObject = {};
                newObject.collectNum = records.items[i].data.collectNum;
                newObject.collectType = records.items[i].data.collectType;
                newObject.memo = records.items[i].data.memo;
                list[i] = newObject;
            }
            Ext.Ajax.request({
                url: './dataacquisition/specimennums_update',
                dataType: 'json',
                method: 'POST',
                params: {
                    jsonData: Ext.encode(list),
                    id: id,
                    collectTime: Ext.Date.format(collectTime, 'Y-m')
                },
                success: function (response, options) {
                    context.record.commit();
                    var responseText = Ext.decode(response.responseText);
                    Amili.amili.FlyTip.fly(responseText.title, responseText.message, responseText.category);
                },
                failure: function (response, options) {
                    var responseText = Ext.decode(response.responseText);
                    Amili.amili.FlyTip.fly(responseText.title, responseText.message, responseText.category);
                }
            });
        }
    }
},

某个单元格不能编辑

beforeedit: function (editor, context, eOpts) {
    if (context.field == 'collectType' && context.record.data.state == 1) {
        return false;
    }
}

删除图标  状态为1显示，状态为0不显示图标。

items: [{
    text: '删除',
    iconCls: 'list-del',
    tooltip: '删除',
    handler: 'onRemoveClick',
    hidden: false,
    getClass: function (v, metadata, record) {
        if (record.data.state == 1) {
            return 'x-hidden';
        }
        return 'list-del'
    }
}]
