Extjs:如何在Extjs tpl中使用带空格的对象键值?

简单的回答是:不要。

var data = {"today date":'12-02-2014' ,"created date":'10-2-1014'};

// notice udpated variable names
var tpl = new Ext.XTemplate('<tpl for=".">','<p>{today_date}</p>','<p>{created_date}</p>','</tpl>');

var fixedData = {};
Ext.each(Ext.Object.getKeys(data), function(key) {
    fixedData[key.replace(/ /g, '_')] = data[key];
});

// test
alert(tpl.apply(fixedData));
