Extjs学习手写(1)

//for test apply
var src = {a:1,b:2,c:{c1:1,c2:2}};
var dest = {};
var defaultv = {cjd:'我'};
var res = Ext.apply(dest,src,defaultv);
console.log(res);
dest = {a:100};
var res1 = Ext.applyIf(dest,src);
console.log(res1);

//for test String format
var arg1 = "我的",arg2="你的",arg3="我们的";
//这里的序号是从0开始递增的.
var txt = String.format('{0}+{1}={2}',arg1,arg2,arg3);//我的+你的=我们的
console.log(txt);

//for test extjs function interceptor
function check(a){
	return a==='cjd';
}
function send(){
	alert("pass");
}
var fn = send.createInterceptor(check);
fn('cjd');//alert pass
//or 
var fn1 = send.createInterceptor(function(a){
	return a==='cjd1';
});
fn1('cjd1');//alert pass
