使用toFixed获取数字字段的十进制数字

Question

I have this field

<input type="number" name="amount" step="0.01" ng-model="amount" />

$scope.amount is a variable with the value in it which is a string so I do this:

$scope.amount = parseInt($scope.amount).toFixed(2);

This does return the value of let's say 0.00 but it is in a string but it won't populate the field as it is only a number field and toFixed(); is returning a string even though I still parsed it.

What is a way around this?

Answer 1

use parseFloat $scope.amount = parseFloat(parseInt($scope.amount).toFixed(2));

toFixed() converts the number to string check here https://www.w3schools.com/jsref/jsref_tofixed.asp
