I have just started with Jest today. I have a simple test file in my __tests__ directory. Here is the current test file: describe('ChangeCalendarView', function() { it('true', function() { expect(3).toBe(3); }) }); This runs with no issue. When I add another file, with the same exact code, other than the description: describe('ChangeTimePeriod', function() { it('true', f
我今天刚刚开始与Jest。 我在__tests__目录中有一个简单的测试文件。 这是当前的测试文件: describe('ChangeCalendarView', function() { it('true', function() { expect(3).toBe(3); }) }); 这运行没有问题。 当我添加另一个文件时,使用相同的确切代码,而不是描述: describe('ChangeTimePeriod', function() { it('true', function() { expect(3).toBe(3); }) }); 然后我得到这个
I used jquery to set hover callbacks for elements on my page. I'm now writing a module which needs to temporarily set new hover behavior for some elements. The new module has no access to the original code for the hover functions. I want to store the old hover functions before I set new ones so I can restore them when finished with the temporary hover behavior. I think these can be stor
我使用jquery为我的页面上的元素设置悬停回调。 我现在正在编写一个模块,它需要为某些元素临时设置新的悬停行为。 新模块无法访问悬停功能的原始代码。 我希望在设置新的悬停函数之前存储旧的悬停函数,以便在完成临时悬停行为时恢复它们。 我认为这些可以使用jquery.data()函数进行存储: //save old hover behavior (somehow) $('#foo').data('oldhoverin',???) $('#foo').data('oldhoverout',???); //set new hover
I've searched a lot these days but i didn't manage to solve my problem. I have the script below which is a simple counter, that counts some stats starting from 0. It starts when my page loads. I would like to fire this event when i scroll to a specific div or id, but only once. I saw a lot examples with .one() method etc. but i didn't find out the proper solution. Here is my scr
我搜索了很多这些天,但我没有设法解决我的问题。 我在下面的脚本是一个简单的计数器,从0开始统计一些统计数据。它在我的页面加载时开始。 我想在我滚动到特定的div或id时触发此事件,但仅触发一次。 我用.one()方法等看了很多例子,但我没有找到合适的解决方案。 这是我的脚本。 <script type="text/javascript"> $.fn.jQuerySimpleCounter = function( options ) { var settings = $.extend({
I am using some third party js and html library(I don't want to update this library). There is an "apply all" button in HTML and what I want to do is "click this button when it becomes visible." <div class="confirm" ng-show="newFilters.length"> .... <button class="btn btn-primary">Apply All</button> </div> EDIT: When the button becomes vi
我正在使用一些第三方js和html库(我不想更新这个库)。 在HTML中有一个“全部应用”按钮,我想要做的是“点击这个按钮,当它变得可见时。” <div class="confirm" ng-show="newFilters.length"> .... <button class="btn btn-primary">Apply All</button> </div> 编辑:当按钮变成可见时,点击功能应该触发。 您可以尝试MutationObserver ,它将侦听元素的css中的更改,然后在发生更改时运行单
Basically, I am wondering if there is a way to automatically run a function when an element becomes hidden or visible, not on a user click but automatically in another script. I don't want this to just run one time, because the elements (such as a slider) constantly change from visible to hidden. Would this be something that jQuery can do with bind? Such as binding the element's visi
基本上,我想知道是否有一种方法可以在元素变为隐藏或可见时自动运行函数,而不是在用户单击时自动运行,而是在另一个脚本中自动运行。 我不想让它只运行一次,因为元素(例如滑块)不断从可见变为隐藏。 这是jQuery可以绑定的东西吗? 比如将元素的可见性绑定到一个函数(我不知道该怎么写) 如果您需要我详细说明我想要做什么,请告诉我。 谢谢 伪代码: $('#element').bind('display:none', function); function(){
This question already has an answer here: jQuery event to trigger action when a div is made visible 21 answers You can achieve it using Jquery. $( '#yourdiv').scroll(function() { if ( $(this)[0].scrollHeight - $(this).scrollTop() <= $(this).outerHeight()){ //ajax method for getting your data //append response data to your div } }); Refer this for How to implement aj
这个问题在这里已经有了答案: jQuery事件触发行动时,一个div可见21答案 你可以使用JQuery来实现它。 $( '#yourdiv').scroll(function() { if ( $(this)[0].scrollHeight - $(this).scrollTop() <= $(this).outerHeight()){ //ajax method for getting your data //append response data to your div } }); 请参阅本文以了解如何使用jQuery实现ajax
Is there any technique or set of techniques that can be used to implement what, in effect, would be an onVisible 'event' in JavaScript? I would like my JavaScript to detect when an element in a web page, such as a paragraph of text, or an image, becomes visible in a browser window as a user scrolls down a page. I would also like a corresponding 'event', onNotVisible, to fire wh
是否有任何技术或一组技术可用于实现什么,实际上,这将是JavaScript中的一个onVisible“事件”? 当用户向下滚动页面时,我希望使用JavaScript来检测网页中的元素(如文本段落或图像)在浏览器窗口中是否可见。 我还希望在浏览器窗口中一次可见的元素不能再被看到时触发相应的'event'onNotVisible。 如果在JavaScript中无法轻松实现,是否有任何可以提供相同功能的浏览器特定事件? 我不得不亲自尝试一下,这就是
Is there a way to detect if the "display" css property of an element is changed (to whether none or block or inline-block...)? if not, any plugin? Thanks Yes you can. DOM L2 Events module defines mutation events; one of them - DOMAttrModified is the one you need. Granted, these are not widely implemented, but are supported in at least Gecko and Opera browsers. Try something alo
有没有办法来检测元素的“显示”CSS属性是否更改(无论是否或块或内联块...)? 如果没有,任何插件? 谢谢 是的你可以。 DOM L2事件模块定义突变事件; 其中之一 - DOMAttrModified是你需要的。 当然,这些并没有得到广泛的实施,但至少在Gecko和Opera浏览器中得到支持。 尝试一下这些方面的内容: document.documentElement.addEventListener('DOMAttrModified', function(e){ if (e.attrName === 'style') { cons
Im trying to create a button that generates already formated divs everytime it is pushed. The divs are composed by forms and their fields should already be filled with data that is stored in variables in javascript. eg. <div id="myDiv_#"> <form id="myForm"> <input type="text" id="start_date" name="start_date" value="someJavascriptVariable" /> <input type="text" id="end_d
我试图创建一个按钮,每生成一个按钮就会生成格式化的div。 div由表单组成,它们的字段应该已经被存储在javascript中的变量中的数据填充。 例如。 <div id="myDiv_#"> <form id="myForm"> <input type="text" id="start_date" name="start_date" value="someJavascriptVariable" /> <input type="text" id="end_date" name="end_date" value="someJavascriptVariable" /> <select name="type" id
So, I know how to create an element in jQuery in various ways. But I've never come across this before today: var myspacer = $('<div />', { "id": "nav-spacer", "height": mynav.outerHeight() }); Later on in the code, this variable is added to the DOM with jQuery's .before() method. Can somebody explain what's going on here? What kind of object is being
所以,我知道如何以各种方式在jQuery中创建元素。 但是我今天之前从未遇到过这样的情况: var myspacer = $('<div />', { "id": "nav-spacer", "height": mynav.outerHeight() }); 在后面的代码中,这个变量通过jQuery的.before()方法添加到DOM中。 有人可以解释这里发生了什么吗? 什么样的对象正在创建? jQuery如何知道如何将它变成HTML元素? 这是jQuery()函数的$( html, props )语
