问题描述

我正在尝试为"SetOutputCurrentPPLowValue"设置为true. & "SetOutputCurrentPPHighValue"；当"SetAlarmValues"被检查.对于此问题，我有以下代码:

I'm trying to set enabled true for "SetOutputCurrentPPLowValue" & "SetOutputCurrentPPHighValue" when "SetAlarmValues" is checked. I have the following code, for this issue:

当页面被加载但是当"SetAlarmValues"被设置时，这些字段被禁用.选中后，它们将保持禁用状态.我不知道为什么.请帮忙！

The fields are disabled when the page is loaded but when the "SetAlarmValues" is checked, they stay disabled. I'm not sure why. Please help!

这是脚本:

function Registration() {
    var self = this;
    //Alarms
    self.setAlarmValues = ko.observable(false);
    self.setOutputCurrentPPLowValue = ko.observable(false);
    self.setOutputCurrentPPHighValue = ko.observable(false);
    self.outputCurrentPPLowValue = ko.observable("");
    self.outputCurrentPPHighValue = ko.observable("");

}



var registerVM = function (countryListJSON, companyListJSON, wellStatusListJSON, territoryListJSON) {
    self = this;

    self.validation = ko.observableArray([]);
    self.savingData = ko.observable(false);
    self.regData = ko.observable(new Registration());
}

推荐答案

在您的代码中，我看到以下语句启用:$ root.regData().setAlarmValues()，并且setAlarmValues值设置为false.仅在将字段setAlarmValues的值设置为true时才会启用.但是正如您提到的，一旦选中此复选框，请确保检查该值是否仍为false或将其更改为True.

In your code i see this statement- enable: $root.regData().setAlarmValues(), and the setAlarmValues value is been set to false. It will only enabled once you set the value of the field setAlarmValues to true. But as you mentioned once the checkbox is checked please make sure to check if the value is still false or is it changed to True.
