load

问题 I have an iframe in my page and when I load the page, the page scrolls to the start on the iframe which is about 200px from the top of the page. If I change the iframe to a div then the page loading is as normal, meaning the page is scrolled to the top. So it is something about the iframe that is causing this. Does anyone know how to prevent this from happening? 回答1: Sorry, this was a dumb question. I just set the style property to display:none; and that solved it. 来源： https://stackoverflow

问题 How do I load an XNA model from a file path instead of from the content (eg. Model.FromStream but it doesnt exist)?? Texture2D has .FromStream , how can I do the equivalent for Model ? 回答1: You can use Content.Load<Model>("Path here, make sure you use drive letter"); If you really need to have a FromStream method on Model you can use extension methods (Not exactly a perfect duplicate of FromStream but it should work): public static Model FromPath(this Model model, ContentManager content,

问题 I have over 1000 data sets I would like to load into R and name each one separately as they are loaded in. I found that to load them I can use the commands: temp = list.files(pattern="*.csv") for (i in 1:length(temp)) assign(temp[i], read.csv(temp[i])) but how would I name each file as it is loaded so I can easily call each one later on? 回答1: It is better to get your data.frame aggregated in a list. Using sapply to loop you get a named list with file names. temp = list.files(pattern="*.csv")

问题 I wrote a shiny app for sports betting which enables me to run a model and pick a winner, add additional variables if I decide to bet on a game and store this in a database, and track my betting performance and adapt strategies using this information. The app works fine so far, but has one major flaw: when I made the calculations and decide to bet on a game, I can simply add another row into a database by using a submit button. The problem is that I have two important columns for data

问题 Is there an event after CSS rules applied to all elements in the DOM ? i know that the binding $(window).load() , from jQuery, is fired when all js and css files are loaded. But not when they are applied (there is a small delay of some milliseconds between applying and inlcuding dynamically, such as: $('#design').attr('href', 'style.css') // design is an <link href="otherstyles.css"> ). 回答1: As per here, you could grab the contents of the CSS file with AJAX and then use jQuery's built in
