高分请教extjs读复杂XML问题

Question

不多说先上代码Ext.onReady(function() {    var myStore = new Ext.data.JsonStore({
        // Load data at once
        autoLoad: true,
        // Override default http proxy settings
        proxy: new Ext.data.HttpProxy({
            // Call web service method using GET syntax
            url: 'PttGetData.asmx/CancelableTerminal',
            // Ask for Json response
            headers: { 'Content-type': 'application/json' }
        }),
        // Root variable
        root: 'd',        fields: ['TerminalId','TermId', 'MsgTime', 'CardId', 'SimNo', 'ShiftSN', 'CmdType', 'CmdMsg', 'IsSucc', 'T_isRec', 'T_IsCommit', 'SendTime', 'RecvTime', 'CommitTime']
    });    var grid = new Ext.grid.GridPanel({
        // Set store
        store: myStore,
        // Columns definition
        columns: [
                        { header: "Terminal ID", width: 300, dataIndex: 'TerminalId', sortable: true },
                         { header: "TermID", width: 300, dataIndex: 'T', sortable: true }                    ], sm: new Ext.grid.RowSelectionModel({ singleSelect: true }),
        viewConfig: {
            forceFit: true
        },
        height: 210,
        split: true,
        region: 'north',
         renderTo: 'CAV'    });
});
我从webservice输出json格式的数据.. 但是我显示不出来.只有XML的<ArrayOfPttCmdDict>

</ArrayOfPttCmdDict>请教大家..我应该如何读取中间每一个值呢?? 

Answer 1

我意思是从XML中取第一个节点的值.. 我在JS里面fields: ['TerminalId','TermId', 'MsgTime', 'CardId', 'SimNo', 'ShiftSN', 'CmdType', 'CmdMsg', 'IsSucc', 'T_isRec', 'T_IsCommit', 'SendTime', 'RecvTime', 'CommitTime'] 这样写并取不到值..除了'TerminalId'   ..  我不明白.. 因为webservice输出的是json格式.. 所以我用jsonStore来处理数据.. 我想做的效果是在gridPanel中显示每一个数值..但是只能显示'TerminalId'而已.

Answer 2

extjs读取json格式的不是正好吗？

Answer 3

不会应用的话就google查一下别人怎么用extjs来使用json格式的：

Answer 4

...我查了两天了... 什么都查不到. 而且.网上面的都只是一些很简单的json读取.. 根本没用. ~~  我不是要页面怎样读出来. 我是要用extjs读出来.然后做一个gridpanel来放.~　现在问题改变了.. 我跟着官方的例子做好了一个gridpanel. 也成功的显示了一些数据.. 然后.我想官方的例子一样当我点击其中一行数据之后. 在grid的下面会显示这行数据相关的东西 在这里.. 我想是. 当选中一行数据. 就会自动填充一个gridpanel 然后把数据填进去..~ 
我把代码放上来.. Ext.onReady(function() {
    var gridDtl;
    var myStore = new Ext.data.JsonStore({
        autoLoad: true,
        proxy: new Ext.data.HttpProxy({
            url: 'PttGetData.asmx/CancelableTerminal',
            headers: { 'Content-type': 'application/json' }
        }),
        root: 'd',
        fields: ['TerminalId']
    });    var grid = new Ext.grid.GridPanel({
        store: myStore,
        columns: [
                        { header: "Terminal ID", width: 300, dataIndex: 'TerminalId', sortable: true }
                    ],
        sm: new Ext.grid.RowSelectionModel({ singleSelect: true }),
        viewConfig: {
            forceFit: true
        },
        height: 210,
        split: true,
        region: 'north'    });
    var ct = new Ext.Panel({
        renderTo: 'CAV',
        frame: true,
        title: 'Book List',
        width: 540,
        height: 400,
        layout: 'border',
        items: [
grid,
gridDtl
]
    });    grid.getSelectionModel().on('rowselect', function(sm, rowIdx, r) {
        var detailPanel = Ext.getCmp('detailPanel');
        var terminalid = r.data.TerminalId;
        var store = store = new Ext.data.JsonStore({
            baseParams: { te: terminalid },
            proxy: new Ext.data.HttpProxy({
                url: 'PttGetData.asmx/qe',
                headers: { 'Content-type': 'application/json' }
            }),
            root: 'd',
            fields: ['TermId', 'MsgTime', 'CardId', 'SimNo', 'ShiftSN', 'CmdType', 'CmdMsg', 'IsSucc', 'T_isRec', 'T_IsCommit', 'SendTime', 'RecvTime', 'CommitTime']        });        gridDtl = new Ext.grid.GridPanel({
            store: store,
            columns: [
                        { header: "信息收发时间", width: 300, dataIndex: 'MsgTime', sortable: true },
                        { header: "终端号", width: 300, dataIndex: 'TermId', sortable: true },
                        { header: "车牌号", width: 300, dataIndex: 'CardId', sortable: true },
                        { header: "终端sim卡号", width: 300, dataIndex: 'SimNo', sortable: true },
                        { header: "作业流水号/航次号/班次号", width: 300, dataIndex: 'ShiftSN', sortable: true },
                        { header: "命令类型", width: 300, dataIndex: 'CmdType', sortable: true },
                        { header: "命令信息内容", width: 300, dataIndex: 'CmdType', sortable: true },
                        { header: "收发是否成功", width: 300, dataIndex: 'IsSucc', sortable: true },
                        { header: "终端是否收到", width: 300, dataIndex: 'T_isRec', sortable: true },
                        { header: "终端是否人工确认", width: 300, dataIndex: 'T_IsCommit', sortable: true },
                        { header: "下发时间", width: 300, dataIndex: 'SendTime', sortable: true },
                        { header: "接收时间", width: 300, dataIndex: 'RecvTime', sortable: true },
                        { header: "人工确认时间", width: 300, dataIndex: 'CommitTime', sortable: true }
                    ],
            viewConfig: {
                forceFit: true
            },
            height: 210,
            split: true,
            region: 'north'
        });
    });
    myStore.load();
});  
现在这段代码什么都没会现显...  请问要怎么样修改呢??

楼主只有2列第一列是对的，能显示吧
第二列的dataIndex是'T'? 你的fields数组中没有'T'当然显示不出来了。{ header: "TermID", width: 300, dataIndex: 'T', sortable: true }
