问题 I tried this code window.open('page2.html','_newtab'); And all it opened was a new window. How do I open a new tab? 回答1: This is a browser setting and not something you can control with code. In my browser, your "window.open" will open a new tab, because that's what I have mine set up to do. In others' browsers, it might open a new window. 回答2: I don't think you can, from HTML / Javascript, indicate that a page should be opened in a new tab. (In fact, your page might be opened to a new window

造轮子-tab组件(上)

1. 如何解决之前遗留的bug 根据错误提示大概确定原因，toast.test.js .style 造成。 用二分法找bug到底是哪一个用例出错。 log 分析代码,mounted和$nextTick是有时间间隙的，得到原因测试用例中mount完了之后立刻click,click之后再$nextTick设置高度,所以可能是click太快了，此时s当$nextTick的时候，已经toast已经被我们关掉了，所以无法设置高度,那么解决方案就是我们就需要模拟用户点击，200ms后再点击 // toast.test.js setTimeout(()=>{ closeButton.click() expect(callback).to.have.been.called done() },200) 2. 对tabs进行需求分析,每一个组件都要进行四步 需求 ui 代码 先考虑用户怎么用 // elementUI的使用方法一 <g-tabs> <g-tabs-item label="美女"> <div> 美女相关咨询 </div> </g-tabs-item> <g-tabs-item label="世界杯"> <div> 世界杯相关咨询 </div> </g-tabs-item> </g-tabs> // elementUI的使用方法二,加icon // 这种使用方法有个问题

Android Bottom Navigation - Maintaining Activity State

由 无人久伴 提交于 2020-01-26 03:14:28
问题 I know it's recommended to use Fragments instead of Activities when working with Bottom Navigation . Due to the current design, I want to avoid having to convert all the Activities The Design: I am using a Bottom Navigation bar like shown Each tab is an Activity . When you tap on any of the tabs, it launches the activity, startActivity(new Intent(getApplication(), TabActivityName.class)); . The problem is that when you switch between these tabs, the state of the Activity is lost. For example:

In the “ActionBarTabsPager” tutorial, getActivity returns null

问题 I have successfully implemented the tutorial: http://developer.android.com/reference/android/support/v4/view/ViewPager.html, as a Tab'ed viewpager activity with fragments on each tab. Each Fragment maintains various UI TextFields etc and everything is working fine with the exception of getActivity(), which returns null when called from any of the fragments. UPDATE: Read this, then please see my own answer below that broadens the scope regarding the cause of this error. Continued: BUT, the

由 余生长醉 提交于 2020-01-25 10:24:07
问题 I'm using jQuery UI Tabs, and these tabs are inside a form. Every tab contains a number of form fields, which can be filled.

Django - custom attributes for model fields

由 与世无争的帅哥 提交于 2020-01-24 22:02:11
问题 Is there a way in Django to add custom attributes to a model's fields (without resorting to subclassing fields)? I would like to only display certain fields in certain sections of my template. This is because eventually each type of field will be displayed in a separate tab. I thought about adding a custom attribute to each field to identify which section/tab it should go in. But, so far, I've had no luck. I have a few field types: class Enum(set): def __getattr__(self, name): if name in self

由 ▼魔方 西西 提交于 2020-01-24 05:22:48
问题 I've a QTabWidget , which contains widgets of different heights (their widths are fixed), however, the default implementation of QTabWidget selects the biggest widget's height as own height. What I would like to know if there's a (possible fast) way to change the size of QTabWidget depending on its current tab, to save space when smaller tabs are shown. 回答1: You can set the size policy of the widget that is displayed to QSizePolicy::Preferred and the other ones to QSizePolicy::Ignored . After

Angular Material Tabs Lazy Load

问题 I have recently started using AngularJS but I have run into a problem when using md-tabs (https://material.angularjs.org/latest/demo/tabs). On my page, I have several tabs and there are approaximately 30 images placed in each tab via ng-repeat. The problem is that all of the images in all of the tabs are loading when the page is opened which is taking a long time. I would prefer if only the content of the first (active) tab was loaded when the page is opened and that the content of all the
