我在一个页面上有 2 个滑块,1 个控制天数,另一个控制要借出的金额。
我有这个计算:
function calculate(){
var days = $("#days-value").val();
var amount = $(".loan-amount-value").val();
var percent = .10;
var interest = (days * amount * percent)/10;
var total = parseInt(amount, 10) + parseInt(interest, 10);
$("#total-repay").val(total);
$("#interest-fees").val(interest);
};
但它仅在页面加载时才有效。当滑块更改时,我需要它进行更新。我知道每次滑块更改时我都需要调用计算函数,但我只是不确定如何编写它。这可能吗?
这是脚本的其余部分:
$(document).ready(function() {
$(function() {
var inputValue = $(".loan-amount-value").val();
$( ".loan-amount-slider" ).slider({
min: 100,
max: 500,
step: 1,
value: 200,
slide: function(event, ui) {
//update loan amount value when sliding loan amount slider
$(".loan-amount-value").val(ui.value);
}
});
//show the loan amount initially
$(".loan-amount-value").val($(".loan-amount-slider").slider("value"));
//when the loan amount changes via user input..
$("#loan-amount-value").change(function(event) {
//change the slider to that amount
$(".loan-amount-slider").slider("option", "value", inputValue);
})
var dayInputValue = $("#days-value").val();
$( ".days-slider" ).slider({
min: 1,
max: 45,
step: 1,
slide: function(event, ui) {
//update day when sliding day slider
$("#days-value").val(ui.value);
}
});
//show the day initially
$("#days-value").val($(".days-slider").slider("value"));
//when the day via user input..
$("#days-value").change(function(event) {
//change the slider to that amount
$(".days-slider").slider("option", "value", dayInputValue);
});
function calculate(){
var days = $("#days-value").val();
var amount = $(".loan-amount-value").val();
var percent = .10;
var interest = (days * amount * percent)/10;
var total = parseInt(amount, 10) + parseInt(interest, 10);
$("#total-repay").val(total);
$("#interest-fees").val(interest);
};
}); });
