Some of the fields on my form can be multi-line, including, for example, the "comments" field. Notice the spacing on the fields after the comments are all ok. because the users can enter multi-line text, I have added the following code to the page, so that it will resize the field appropriately. Basically just handle the "OnKeyUp" event on the textbox to resize it so that
我的表单中的某些字段可以是多行的，例如“评论”字段。 在注释完全正确后注意字段上的间距。 因为用户可以输入多行文本，所以我在页面中添加了以下代码，以便它可以适当调整字段的大小。 基本上只需处理文本框上的“OnKeyUp”事件来调整它的大小，使其显示高度等于其滚动高度。 function AutoExpandTextbox(txtbox) { txtbox.style.height = "1px"; txtbox.style.height = (4 + txtbox.scrollHeight) + "px
So far most of "starter boilerplates" and some posts about react / redux I've seen encourage usage of immutable.js to address mutability. I personally rely on Object.assign or spread operators to handle this, hence don't really see advantage in immutable.js as it adds additional learning and shifts a bit from vanilla js techniques used for mutability. I was trying to find vali
到目前为止，大部分“初学者样板”和一些关于react / redux的帖子我都看到鼓励使用immutable.js来解决可变性问题。 我个人依赖Object.assign或传播运算符来处理这个问题，因此在immutable.js中并没有真正看到优势，因为它增加了额外的学习，并且从用于可变性的vanilla js技术转移了一点。 我试图找到一个切换的正确理由，但无法因此我在这里问，看看它为什么如此受欢迎。 这是关于效率。 持久数据结构 持久数据结构通过始
I've created 2 fiddles, clicking on the Products list item makes a submenu appear, I need it to transition however. The only difference between the fiddles is that the 2nd link works like I need it to but with a "hack", tested in firefox and chrome but it didn't work in edge. https://jsfiddle.net/tzswq34a/2/ https://jsfiddle.net/tzswq34a/3/ The only difference in code is
我创建了2个小提琴，点击产品列表项可以出现一个子菜单，但我需要它来转换。 这两个小提琴之间的唯一区别是，第二个链接像我需要的那样工作，但带有一个“黑客”，在firefox和chrome中测试过，但它并没有在边缘工作。 https://jsfiddle.net/tzswq34a/2/ https://jsfiddle.net/tzswq34a/3/ 代码中的唯一区别在于第二个链接在Javascript部分的第10行中有以下代码行： $submenu.height(); 为什么查询子菜单的高度使其工作？
I am using the fullcalendar jquery plugin v2.6.1. Actually, I want to prevent the highlighted option of an external events while dragging to the calendar. Is there any possible way to disable the fc-highlight from the event or any option to show the highlight on the basis of event size. I mean to say that I have an external event with start and end time eg the event starts from 10:00 and ends
我正在使用fullcalendar jquery插件v2.6.1。 实际上，我想在拖拽到日历时防止突出显示的外部事件选项。 是否有任何可能的方法来禁用事件中的fc-highlight或者根据事件大小显示突出显示的任何选项。 我的意思是说，我有一个开始和结束时间的外部事件，例如事件从10:00开始，到11:00结束，但当我将该事件拖到日历中时， fc-highlight总是覆盖两个小时插槽。 附图如下 因此，在图片中，红色笔触事件2中的灰色突出显示的框仅
I don't know if it is a feature or a bug. But the event end value is set to null if allDay is true. This is the function where the event is updated: change: function (eventModel) { var currEvId = eventModel.get('_id'); var fcEvent = $("#calendar").fullCalendar('clientEvents', currEvId)[0] || {}; console.log("end before update : " + fcEven
我不知道它是一个功能还是一个错误。 但是，如果allDay为true，则事件结束值将设置为null。 这是事件更新的功能： change: function (eventModel) { var currEvId = eventModel.get('_id'); var fcEvent = $("#calendar").fullCalendar('clientEvents', currEvId)[0] || {}; console.log("end before update : " + fcEvent.end); fcEvent.title = alvEv
In my app, I set a cookie and then call fetch('/foo', {credentials: 'same-origin'}) . This is intercepted in the service worker which uses caches to cache the request and response. The response has Vary: Cookie set. Then, I change the cookie and call fetch again as above. But when I call caches.match in the service worker, the old request is matched! Why is this happening? C
在我的应用程序中，我设置了一个cookie，然后调用fetch('/foo', {credentials: 'same-origin'}) 。 这在使用caches来缓存请求和响应的服务工作者中截获。 响应有Vary: Cookie集。 然后，我改变cookie并像上面那样再次调用fetch 。 但是当我在服务人员中调用caches.match时，旧的请求是匹配的！ 这是为什么发生？ 我可以修复它吗？ 我不能评论（低代表），所以我在这里发布。 服务人员不能拦截Cookie。
Is there any JavaScript syntax that lets me do the following more succinctly: class MyClass { static get myProp() { return 1; } } Not a huge deal, but I'd like to know if there was something that was like an arrow function that lets me make it just a little more streamlined, something like: class MyClass { static get myProp = () => 1; } I know I could write it like
有什么JavaScript语法可以让我更简洁地做到以下几点： class MyClass { static get myProp() { return 1; } } 没有什么大不了的，但我想知道是否有什么东西像箭头函数那样让我更简化一些，如： class MyClass { static get myProp = () => 1; } 我知道我可以这样写（虽然不是一个安全的等价物）： class MyClass {} MyClass.myProp = 1; 或者这更难以阅读和更长的选择： class MyClass {} Object.d
I am trying to request data by ajax from ripe.net, but the ajax request never triggers the success function, even through I get an http Response 200. My current code looks like this: $.ajax({ headers: { Accept : "application/json; charset=utf-8", }, type: 'GET', url: 'http://rest.db.ripe.net/search', data: { 'source' : 'ripe', 'query-string': '172.217.
我试图通过ajax从ripe.net请求数据，但ajax请求从未触发成功函数，即使通过我得到一个http响应200.我目前的代码如下所示： $.ajax({ headers: { Accept : "application/json; charset=utf-8", }, type: 'GET', url: 'http://rest.db.ripe.net/search', data: { 'source' : 'ripe', 'query-string': '172.217.16.67', 'type-filter': 'inetnum' }, success: functio
I'm trying to learn some html/css/javascript, so I'm writing myself a teaching project. The idea was to have some vocabulary contained in a json file which would then be loaded into a table. I managed to load the file in and print out one of its values, after which I began writing the code to load the values into the table. After doing that I started getting an error, so I removed al
我正在尝试学习一些html / css / javascript，所以我正在写一个教学项目。 这个想法是将一些包含在json文件中的词汇表加载到表中。 我设法加载文件并打印出其中的一个值，之后我开始编写代码将值加载到表中。 这样做后，我开始出现一个错误，所以我删除了我写的所有代码，只留下一行（与之前工作过的同一行），只有错误仍然存在。 错误如下： Uncaught SyntaxError: Unexpected token o (anonymous function)script.js:
I was able to get this to work with fontkit by selecting a font from the font collection. I haven't found a case yet where using either of the TTFs included in the "Apple Color Emoji.ttc" gives different results. const fs = require('fs'); const fontkit = require('fontkit'); const emoji = require('node-emoji'); const font = fontkit.openSync('./Apple Color Emoji.ttc').fonts[0]; let
通过从字体集合中选择一种字体，我能够使用fontkit进行工作。 我还没有发现使用“Apple Color Emoji.ttc”中包含的任何一个TTF给出不同结果的情况。 const fs = require('fs'); const fontkit = require('fontkit'); const emoji = require('node-emoji'); const font = fontkit.openSync('./Apple Color Emoji.ttc').fonts[0]; let emo = emoji.get('100'); let run = font.layout(emo); let glyph = run.glyphs[0].getImageFor
