Question

我遇到一个问题，从服务器返回的某些值会在firebug中抛出“代码12”并导致在extjs中浮动的“正在加载”消息，这些消息永远不会消失，似乎挂起了我的页面。这个问题只发生在firefox中。我发现我可以通过设置“＆amp;”来一致地复制问题在GridPanel中的一个值中，但其他值（如富文本格式）有时也会抛出代码12.我发现如果我进入opera中的页面，我可以修复网格中的数据面板并将其保存到服务器。然后刷新firefox页面，一切都回到原来的样子。是否有一些分隔符或我可以围绕这些值来阻止这种情况发生？我的extjs可以让我保存到服务器的东西，我不明白如何将它恢复导致问题。

在萤火虫中：

An invalid or illegal string was specified" code: "12
[Break On This Error] (function(){var D=Ext.lib.Dom;var E=Ex...El.cache;delete El._flyweights})})();

从服务器返回的示例JSON（注意“200＆amp; 5”会导致错误，“200和5”将正常工作）

{"summaryList":[{"shot":"","seq":"200 & 5","active":9998,"tag":"","file":"","id":"137943329348950905822686689581598049837","quick_comments":"","comments":"","priority":"","asset":"","prod":"dragon","type":"","store":"","submitby":"jstratton","status":"ip","format":"","date":"2011_5_10","approval":"hofx_pm","name":"jstratton","notes":"","uri":"137943329348950905822686689581598049837","dept":"fx","time":"10 May 2011 13:56:30","order":2}], "success":true}

JSON商店和GridPanel

var summaryStore = new Ext.data.JsonStore({
    url: 'summaryList',
    root: 'summaryList',
    baseParams :    {
        show: showSelect.getValue(),
        dept: deptSelect.getValue(),
        approval: typeSelect.getValue(),
        roundDate: roundDateField.getValue(),
        user: summaryUser.getValue(),
    },
    autoLoad: true,
    fields: [],
});

var summaryGrid = new Ext.grid.GridPanel({
    store: summaryStore,
    columns : [],
    // turn off multi-selection for now
    tbar : [activeButton,
            removeButton,
            ' ',
            exportToSpreadsheetButton,
            refreshButton,
        ],
    renderTo: 'summaryTab',
    autoHeight: true,
    loadMask: {msg: 'Loading information. Thank you for your patience.'},
    autoExpandColumn: 'comments',
    autoSizeColumns: true,
    ddGroup: 'summaryGridDD',
    enableDragDrop: true,
    viewConfig: {
        forceFit: true,
    },
    titleCollapse : true,
    collapsed: false,
    stripeRows: true,
    title: 'Summary',
    frame: true,
});

你的'＆amp;'直接放在HTML中，您需要HTML转义您的内容。
