我不断得到总 first.tofixed(2) 不是一个函数，它引导我到这一行 [重复]

Question

...var totalFirst = bookFirst+exFirst; totalFirst = totalFirst.toFixed(2);

代码有什么问题？

{

var layStakeWin = (backStake*(backOdds-1.0)*(1.0-backCom)+backStake)/(layOdds-layCom);
layStakeWin = layStakeWin.toFixed(2);

var layStakePlace = (backStake*(((backOdds-1.0)/placeTerms)+1)*(1.0-backCom))/(layOdds-layCom);
layStakePlace = layStakePlace.toFixed(2);

var bookFirst = (backStake*(backOdds-1.0)*(1.0-backCom))+(backStake*(backOdds-1.0)/placeTerms*(1.0-backCom));
bookFirst = bookFirst.toFixed(2);

var exFirst = 0-(layStakeWin*(layOdds-1.0))-(layStakePlace*((layOdds/placeTerms)-1.0));
exFirst = exFirst.toFixed(2);

var totalFirst = bookFirst+exFirst;
totalFirst = totalFirst.toFixed(2);

var bookStandard = 0-backStake+(backStake*(backOdds-1.0)/placeTerms*(1-backCom));
bookStandard = bookStandard.toFixed(2);

var exStandard = (layStakeWin*(1-layCom))-(layStakePlace*(layOdds-1.0));
exStandard = exStandard.toFixed(2);

var totalStandard = bookStandard+exStandard;
totalStandard = totalStandard.toFixed(2);

var bookExtra = 0-backStake+(backStake*(backOdds-1.0)/placeTerms*(1.0-backCom));
bookExtra = bookExtra.toFixed(2);

var exExtra = (layStakeWin*(1-layCom))+(layStakePlace*(layOdds-1.0));
exExtra = exExtra.toFixed(2);

var totalExtra = bookExtra+exExtra;
totalExtra = totalExtra.toFixed(2);

var bookNo = 0-backStake-backStake;
bookNo = bookNo.toFixed(2);

var exNo = (layStake*(1.0-layCom))+(layStakePlace*(layOdds-1.0));
exNo = exNo.toFixed(2);

var totalNo = bookNo+exNo;
totalNo = totalNo.toFixed(2);

}

Answer 1

问题是 toFixed() 返回一个字符串。

要解决这个问题，在任何地方使用 toFixed()，将其包装在 parseFloat() 函数中。

例如，

layStakeWin = parseFloat(layStakeWin).toFixed(2);

请在您使用 toFixed() 的任何地方进行此更改。

{

var layStakeWin = (backStake*(backOdds-1.0)*(1.0-backCom)+backStake)/(layOdds-layCom);
layStakeWin = parseFloat(layStakeWin).toFixed(2);

var layStakePlace = (backStake*(((backOdds-1.0)/placeTerms)+1)*(1.0-backCom))/(layOdds-layCom);
layStakePlace = parseFloat(layStakePlace).toFixed(2);

var bookFirst = (backStake*(backOdds-1.0)*(1.0-backCom))+(backStake*(backOdds-1.0)/placeTerms*(1.0-backCom));
bookFirst = parseFloat(bookFirst).toFixed(2);

var exFirst = 0-(layStakeWin*(layOdds-1.0))-(layStakePlace*((layOdds/placeTerms)-1.0));
exFirst = parseFloat(exFirst).toFixed(2);

var totalFirst = bookFirst+exFirst;
totalFirst = totalFirst.toFixed(2);

var bookStandard = 0-backStake+(backStake*(backOdds-1.0)/placeTerms*(1-backCom));
bookStandard = parseFloat(bookStandard).toFixed(2);

var exStandard = (layStakeWin*(1-layCom))-(layStakePlace*(layOdds-1.0));
exStandard = parseFloat(exStandard).toFixed(2);

var totalStandard = bookStandard+exStandard;
totalStandard = totalStandard.toFixed(2);

var bookExtra = 0-backStake+(backStake*(backOdds-1.0)/placeTerms*(1.0-backCom));
bookExtra = parseFloat(bookExtra).toFixed(2);
