javascript - How to convert a string return from a JQuery slider UI into a number

Question

I have two sliding bars and I want to get the value the user sets them to and do some maths on it. var days and var total are my attempts to do this. I was taking it that the UI slider stores its values as stings and not integers. But both my attempts below, then use either just return a NaN value? So what am I doing wrong?

var days = parseInt($(this).attr('#day_output'), 10);
var total = parseInt($('#amount_outputTotal'));
var fees = 5;
var valueout;

valueout = 60 * days + fees;

$(document).ready(function() {
    $('#Output').html(valueout);
});

Many Thanks Glenn.

Answer 1

我们的项目之一使用 jqueryUI ahs 以下代码：

fixed = $().fixFloat(ui.value);

我知道这可能不适合您的需求。

尝试从 parseInt 更改为 parseFloat 并通过控制台输出：

$(this).attr('#day_output')

为什么这里没有 .attr 或 .val 之类的东西？

$('#amount_outputTotal')

Answer 2

为什么作为数字表示的滑块将值存储为字符串？您可以使用以下代码获取值（或值，如果有两个句柄）

var val_single = $('#your_slider').slider('value');

var val_array = $('#your_slider').slider('values');
