Phone.js点击工具栏上的行动

Question

还有就是我要添加按钮“返回”到dxToolbar（PhoneJS）问题 。通过点击这个按钮我应该回到前一页。但是通过点击工具栏的名称会出现“一些div区块”。这是交易：当我点击'返回'按钮之前导航到前一页的“一些div块”出现。我应该做些什么来阻止事件的传播？ 我试图用jQuery做的，但它并不能帮助

JS文件

toolbarKeyItems = [ 
     { align: 'left', widget: 'button', options: { type: 'back', text: 'Back', clickAction: '#key' } }, 
     { align: 'center', text: 'Alliance' } 
    ]; 
    toolbarCategoryItems = [ 
     { align: 'left', widget: 'button', options: { type: 'back', text: 'Back', clickAction: '#category' } }, 
     { align: 'center', text: 'Ownership' } 
    ]; 

    popupVisible = ko.observable(false); 

    data = [ 
     { id: 1, name: 'Year of Permanent Location', value: '', key_id: 1, category_id: 1 }, 
     { id: 2, name: 'Previously Known As', value: 'St. Marks', key_id: 1, category_id: 2 }, 
     { id: 3, name: 'Year Building was Built', value: '1925', key_id: 1, category_id: 3 }, 
     { id: 4, name: 'Own or Lease', value: 'own', key_id: 2, category_id: 2 } 

    ] 

    lengthDescription = " "; 

    passMode = "password"; 
    secretDescription = "St. Marks"; 

    readonly = true; 
    readonlyDescription = "1925"; 
    own = "Own"; 

    inpClick = function() { 
     enable: true; 
    } 

    showScroll = function() { 
     var value = $('#scrollView').css('display'); 
     if (value == 'none') 
      $('#scrollView').css('display', 'block'); 
     else 
      $('#scrollView').css('display', 'none'); 
    } 

    MyApp.data = function() { 
     var self = this; 
     self.label, 
     self.value, 
     self.key_id, 
     self.category_id; 

     self.findDataWithId = function() { 
      var dataWithId = Array(); 
      for (i = 0; i < data.length; i++) { 
       if ((data[i].key_id == MyApp.app.keyId) && (data[i].category_id == MyApp.app.categoryId)) { 
        dataWithId[dataWithId.length] = data[i]; 
       } 
      } 
      return dataWithId; 
     } 

     self.finalDataSource = ko.observableArray(self.findDataWithId()); 

     self.viewRendered = function() { 
      $('.contentContainer').height($("body").height() - $(".toolbarsContainer").height()); 
     } 

     self.viewShown = function() { 
      self.finalDataSource(null); 
      self.finalDataSource(self.findDataWithId()); 
     } 

     return self; 

    } 



    showPopup = function() { 
     popupVisible(true); 
    } 

    closePopup = function() { 
     popupVisible(false); 
    } 

    fromDataToKeys = function (event) { 
     event.preventDefault(); 
     stopPropagation(); 
     MyApp.app.navigate('key'); 
    } 

当我点击“工具栏从back'按钮，showScroll功能也起作用。

Answer 1

onItemClickAction: function (e) {   
      if (e.itemData.options && e.itemData.options.type == 'back') {    
       e.jQueryEvent.stopPropagation(); 
      } 
} 

这就是DevExpress团队的回答。它的工作原理。

Answer 2

不知道您的具体环境，但要防止从ASP.NET DevExpress的控件的WebForms起泡，使用下面的事件。

下面的行添加到Page_Load事件（例如，C＃）：

DevExpress.Web.ASPxClasses.ASPxWebControl.RegisterBaseScript(Page); 

在JavaScript的事件处理程序中，添加以下：

ASPxClientUtils.PreventEventAndBubble(e.htmlEvent); 

其中e是DevExpress的标准事件参数传递给事件处理程序。
