Question

，我的html页面上有一个滑块，它有一个可观察的数据绑定。像这样。

<input id="ex2" data-slider-id="ex2Slider" type="text" data-bind="sliderValue: {value: borrowOrInvestAmount, min:0, max: 5000, step: 1, formatter:formatter2}"
        style="display: none;">

而且我还有一张表显示出这样的兴趣。

<td <input data-bind=" valueUpdate: 'afterkeydown'"><input data-bind="value: amount1"/></td>

基本上我想要的是，当我更改滑块上的值时，它应该调用此函数，该函数从可观察的borrowOrInvestAmount中获取值并且应该返回将被放入观察中并显示在桌面上的利率。每次滑块值改变时，它应该再次调用该函数。

function DoBusinessViewModel(root) {
            var self = this;
            self.items = ko.observableArray();
            self.itemsNotFoundMsg = ko.observable(null);
            var borrowOrInvestAmount_tmp = 0;
            var moneyBorrOrInvUri;
            if (root.boolInvestments()) {
                moneyBorrOrInvUri = BASEURL + 'index.php/moneyexchange/SearchRequestsOrInvestments/' + auth + '/' + root.borrowOrInvestAmount() + '/' + root.borrowOrInvestCurrency() + '/' + 0 + '/' + 1;
            } else {
                moneyBorrOrInvUri = BASEURL + 'index.php/moneyexchange/SearchRequestsOrInvestments/' + auth + '/' + root.borrowOrInvestAmount() + '/' + root.borrowOrInvestCurrency() + '/' + 0 + '/' + 0;
            }

            $.ajax({
                type: 'GET',
                url: moneyBorrOrInvUri,
                contentType: 'application/json; charset=utf-8'
            })
            .done(function(BorrowOrInvestDetails) {
               $.each(BorrowOrInvestDetails, function (index, item) {
                   self.items.push(item);
/* here is where I am trying to get the value of interest from  for the table*/
                   self.interest(self.item()[0].Interest);

                   borrowOrInvestAmount_tmp += parseFloat(item.borrowOrInvestAmount);
                   /* If we are reading borrowing request and thee are any requests with payment_term = 2 = Monthly,
                    * we must set root.paymentTerm observable to 2 = Monthly. */
                   if (!root.boolInvestments()) {
                       if (item.payment_term == 2) {
                           if (root.paymentTerm() == 1) {
                                root.paymentTerm(2);
                           } 
                       }
                   }
                });
                root.borrowOrInvestAmount(borrowOrInvestAmount_tmp.toFixed(2));
                root.borrowOrInvestAbbreviation(self.items()[0].Abbreviation);
                if (root.boolInvestments()) {
                    root.getFee(root.borrowOrInvestAmount(), root.borrowOrInvestCurrency(), 'money_request', 'borrow');
                } else {
                    root.getFee(root.borrowOrInvestAmount(), root.borrowOrInvestCurrency(), 'money_offer', 'invest');
                }
                root.getPaymentPlanForMultibleItems(self.items());


            })
            .fail(function(jqXHR, textStatus, errorThrown) {
                self.itemsNotFoundMsg(errorThrown);
            })
            .always(function(data){               
            });   
        };

由于我将值borrowOrInvestAmount添加到滑块我不确定它是否实际调用了dobusinessfunction。不知道我错过了什么。

更改滑块调用knockout js功能
