getCmp方法其实是Ext.ComponentMgr.get方法的简写形式。getCmp方法中只有一个参数,也就是组件的id。比如下面的代码: Ext.onReady(function(){ var h=new Ext.Panel({ id:"h2",title:" ",renderTo:"hello",width:300,height:200}); Ext.getCmp("h2").setTitle("新的标题"); ...
The library exports a single function: Big, the constructor of Big number instances. It accepts a value of type Number, String or Big number Object. x = new Big(123.4567) y = Big('123456.7e-3') // 'new' is optional z = new Big(x) x.eq(y) && x.eq(z) && y.eq(z) // tr...
