visible

react,单实例登陆框，可以通过SingleGitLogin.show()进行调用。 但是为什么是单实例，其实我并不是非常清楚，如果大神能够解释就好了。 import GitLogInfo from '@/components/GitLogInfo/GitLogInfo' import SingleDemo from './SingleDemo'; import React from 'react'; import { Modal, Radio, Alert } from 'antd' import RadioGroup from 'antd/lib/radio/group'; import ReactDOM from 'react-dom' import { LoginModal } from '@/components/ProjSpace/ModalComponents/SingleDemo' import Pubsub from 'pubsub-js' let index = 0; let div; function domRender(reactElem, node) { //let div; console.log(index++, "this is domRender", div); if (node) { div = typeof node === 'string'

I have list of thumbs in a scrollable div, animated with next/prev button. Each click on "next "button should match the attribute of the first visible element. Each click on "prev" button should give me the attribute of the last visible element. I don't really know how to mathematically solve that, because the scroll distance is variable when the list ends. Can someone please help me out? HTML $<div id="scrollContent"> <ul id="assetList"> <li data-asset-id="15201"></li> <li data-asset-id="15202"></li> <li data-asset-id="15203"></li> ... </ul> </div> <a class="next" href="#">next</a> <a class=

This is my div <div id="car2" style="display:none;"></div> Then I have a Show button that will show the div when you click: $("show").click(function() { $("$car2").show(); }); So right now I want to check if the div #car2 is still hidden before form submission: if($('#car2').is(':hidden')) { alert('car 2 is hidden'); } Now here is the problem. Although the div #car2 already show, I still got alert message which means that jQuery assumes the div #car2 is still hidden. My jQuery version is 1.7. Thanks. EDIT: As jasper said, my code is correct and can be run via this demo . What i suspect there

清除浮动的四种方式及其原理理解 本文介绍了四种清除浮动的方法，并尝试解释其原理。在理解了各种清除浮动的原理之后，你会发现，很多清除浮动的方法本质上其实是一样的。掌握这些原理，相信你可以根据场景和需求，灵活运用原则发展出不同的清除浮动的方法，而不再死记或拘泥于文中提到的方法。 一、为什么要清除浮动 在讲清除浮动的方法之前，我们先来了解一下为什么要清除浮动，清除浮动的目的是什么，即，要解决什么样的问题。来看一个浮动的例子(略去了文字内容)： <div class="topDiv"> <div class="floatDiv">float left</div> <div class="textDiv">...</div> </div> <div class="bottomDiv">...</div> 其样式为： .topDiv { width: 500px; border: 2px solid black; } .floatDiv { width: 100px; height: 100px; border: 2px dotted red; color: red; margin: 4px; float: left; } .bottomDiv { width: 500px; height: 100px; margin: 5px 0; border: 2px dotted black; }

I am new to the forum, so please indulge me if my post is incomplete. I have a very simple pivot table with one row field, one column field, one data field and one filter field. Row fields are displayed based on the filter setting. Using VBA, my intent is to loop through all row pivotitems and column pivotitems and get the corresponding field names and data values and display them as a sanity check. This is a start of a bigger project. here is the main loop (showstring is displayed on the screen): showstring = "" For rowFldNo = 1 To pvt.RowFields.Count For colFldNo = 1 To pvt.ColumnFields

I've examined multiple answers on this site but they haven't been able to solve my problem for whatever reason ( how to select a particular tab from other page using anchor tag in JQuery..? ). I am only testing this on my local computer so I'm not sure if that would have an impact. I want to link to each tab from the current page as well as from other pages. Right now I am able to click each tab and it works perfectly and the site URL changes (#tab1, #tab2 etc). However, for example, if I click the Tab 1 Link (not the actual tab, but a link on the page that is targeted at tab 1) while Tab 2 is

when i click on #button , it's stilling doing the 'do something' , even though .wrapper is animating and .wrapper span is not visible. so it's not following the rules. what's wrong? $('#button').click(function(){ if( $('.wrapper').not(':animated') && $('.wrapper span').is(':visible') ) { //do something } }) Here you have a working demo : $('#button').click(function(){ if( $('.wrapper:animated').length>0) { $(".wrapper").text("animating") ; } if( $('.wrapper:animated').length<1) { $(".wrapper").text("not animating") ; } }) This is a bit cleaner without the if statements. working demo $('#button
