使用淘汰赛js弹出

2022-01-20 00:00:00 dialog popup javascript knockout.js viewmodel

我正在将我的一个旧 jquery 插件从 DOM 丛林迁移到这个花哨的 mvvm 框架淘汰赛.

i'm migrating one of my older jquery plugins from DOM jungle to this fancy mvvm framework knockout.

我将使用哪种技术来正确显示弹出容器?我必须通过调用"填充它，因为我每次都会得到一个 json 提要.

Which technique would i use to properly display a popup container? I ahve to populate it 'by call' since i get a json feed every time.

我尝试了一种使用 with 绑定的方法，但它仍然尝试在第一次运行时填充部分.

I tried an approach using the with binding, but it still attempts to populate the partial at its first runtime. 

<!-- ko with: daySubmitFormViewModel -->
    <div class="ec-consulation-lightbox">
        <form id="cForm" class="form-container">
           // Some bindings here.
        </form>
    </div>
<!-- /ko with: -->

推荐答案

也可以不用自定义绑定.示例如下

It can be done without custom binding as well. Example is below

            <div class="modalWindowBackground" data-bind="visible: popupDialog" >
                <div class="modalWindow" data-bind="with:popupDialog">
                    <div class="content">
                        <h2 data-bind="text: title"></h2>
                        <p>
                            <span data-bind="text: message"></span>
                        </p>
                        <div class="buttonSpace">
                            <input type="button" class="closeButton" data-bind="value: closeButtonText, click: $root.hidePopupDialog" />
                        </div>                            
                    </div>
                </div>
            </div>

视图模型代码:

    self.showAlert = function (title, message, closeButtonText) {
        self.popupDialog({ title: title, message: message, closeButtonText: closeButtonText });
    };
    self.hidePopupDialog = function () {
        self.popupDialog(null);           
    };

  //Code which opens a popup
  self.remove = function () {
        .... some code ...
        if (someCondition) {
          self.showAlert('SomeTitle', 'Message', 'OK');
          return;
        }
        .... some code ...
   };
