javascript hash表写法 以及 单元测试的例子
以下的例子完成功能,就是输入省市的拼音,返回中文的表达式。
涉及到hash类,以及单元测试

"shanxi":"山西",
"Shaanxi":"陕西",
"Chekiang":"浙江",
"Zhejiang":"浙江",
"Nanking":"南京",
"Nanjing":"南京",
"Hohhot":"呼和浩特",

"transformUpperCase":function(myinput){
myinput=myinput.replace(/\w/g,function(s){returns.toLowerCase();});
myinput=myinput.replace(/\s/g,"");
return(myinput);
},
"getCN":function(myinput){
return(sheng[myinput]);//返回类属性值,也可以看做哈希表值,是用【】来取得
}
}
functionassert(bCondition,sErrorMsg){
if(!bCondition){
console.log(sErrorMsg);
//thrownewError(sErrorMsg);
}else{
console.log("passed");
}
}
/*单元测试
assert(sheng.transformUpperCase("ShanXi")=="shanxi","testfailed");
assert(sheng.transformUpperCase("Shanxi")=="shanxi","testfailed");
assert(sheng.transformUpperCase("ShanXi")=="shanxi","testfailed");
*/
console.log(sheng.getCN(sheng.transformUpperCase("Shanxi")));
console.log(sheng.getCN("shanxi"));
