js补环境会用到的代码

let obj = window.location
let names=Object.getOwnPropertyNames(obj)
let new_map = {}
for(let key of names){
    var value =obj[key]
    if (typeof (value)=="function"){
        value = `function ${value.name}() {}`
    }else if(typeof(value)==="object" ){
        value="{}"
    }
    new_map[key]=value
}
copy(new_map)
