先看常规的条件语句的写法:
function getInitData(columnType){
if(columnType == "baiduZhidaoNum"){
return {searchText:"", href:""};
}else if(columnType == "weBo"){
return {weiboType:"xinlangWeibo",weiboUrl:""};
}else if(columnType == "APPDownload"){
return {downLoadType:"templateSetting"};
}else if(columnType == "contactPhone"){
return {phoneArray:""};
}else if(columnType == "inlineMap"){
return {address:"", latitude:"", longitude:""};
}else if(columnType == "weStore"){
return {weiStoreType: "taobaoStore", storeWebAddress:""};
}else if(columnType == "weRecruit"){
return {jobType:"weijob_zhaopinUrl", content:"", weijobUrl:""};
}
}
拒绝if else之后大概是这样:
/*
这里使用了ES6的Arrow Function,
var fun = ()=>({searchText:"", href:""})
等价于:
var fun = function(){
return {searchText:"", href:""}
}
或:
var fun = (arg1, arg2)=>({searchText: arg1, href:arg2})
等价于:
var fun = function(arg1, arg2){
return {searchText: arg1, href:arg2}
}
*/
function getInitJumpPage(columnType){
return {
"baiduZhidaoNum" : ()=>({searchText:"", href:""}),
"weBo" : ()=>({weiboType:"xinlangWeibo",weiboUrl:""}),
"APPDownload" : ()=>({downLoadType:"templateSetting"}),
"contactPhone" : ()=>({phoneArray:""}),
"inlineMap" : ()=>({address:"", latitude:"", longitude:""}),
"weStore" : ()=>({weiStoreType: "taobaoStore", storeWebAddress:""}),
"weRecruit" : ()=>({jobType:"weijob_zhaopinUrl", content:"", weijobUrl:""}),
}[columnType]();
