So I am trying to find the height of my images then add a top margin this enables me to impose aa vertical center. I'm running this code, and on an F5 refresh I get correct height but on CTRL+F5 refresh it gives me a much smaller height. I kind of assume this is a loading/delay thing, but I am using document ready so not really sure whats going on. I tried using a php function but it slow
所以我试图找到我的图像的高度,然后添加一个顶部边距,这使我可以施加一个垂直中心。 我运行这个代码,并在F5刷新我得到正确的高度,但在CTRL + F5刷新它给我一个小得多的高度。 我有点认为这是一个加载/延迟的事情,但我正在使用文档准备好,所以不知道发生了什么事情。 我尝试使用PHP函数,但它令人惊讶地减慢了网站,所以必须坚持使用jQuery。 你可以看到它在这里工作。 www.mzillustration.com jQuery(document).re

I ran into a problem the other day, and asked the great stack community for a solution. The problem: I nested the same module in other modules but I was defining state in this way: state: { // some state here } What was happening is all of my modules despite seeming being nested under disparate modules all shared the same state. The solution state() { return { // state here inste
有一天我遇到了问题,并向伟大的堆栈社区寻求解决方案。 问题: 我在其他模块中嵌套了相同的模块,但我是这样定义状态的: state: { // some state here } 发生了什么是我的所有模块,尽管看起来被嵌套在不同的模块中,所有模块都共享相同的状态。 解决方案 state() { return { // state here instead } } 解决方案是有一个函数返回状态,而不是将其定义为对象文字。 为什么有点合理。 这是我的问题 新

I have a table, and I'm allowing users to 'select' multiple rows. This is all handled using jQuery events and some CSS to visually indicate the row is 'selected'. When the user presses shift, it is possible to select multiple rows. Sometimes this cause text to become highlighted. Is there anyway to prevent this? 有一个CSS3属性。 #yourTable { -webkit-touch-callout: non
