r mutate_each function is deprecated

问题 I use the function mutate_each from the tidyverse package and I get a message this function is deprecated. I would like to use the other functions that are not deprecated to change field types. Below is a reproducible example of how I currently employ mutate_each. library(tidyverse) set.seed(123) df <- data.frame(FirstName = sample(LETTERS[1:2],size=3, replace=TRUE), LastName = sample(LETTERS[3:6],size=3, replace=TRUE), StartDate = c("1/31/2000","2/1/2000","3/1/2000"), EndDate = c("1/31/2010"

Simple jquery .hover() method for each class element

我怕爱的太早我们不能终老 提交于 2020-01-04 01:50:12
问题 haven't done much jquery and ran into a problem. I'd like to bind hover event for all div's with class .social-tile. I do it like this: $(function(){ var social_default = $('.social-tile').css('margin-right'); $('.social-tile').each(function(){ $(this).hover(function(){ $(this).animate({ 'margin-right': '0px' },500); },function(){ $(this).animate({ 'margin-right': social_default },500); }); }); }); When I hover over one element, animations for all divs are triggered and they move all at one

jquery的$().each,$.each的区别

在jquery中,遍历对象和数组,经常会用到$().each和$.each(),两个方法。两个方法是有区别的,从而这两个方法在针对不同的操作上,显示了各自的特点。 $().each,对于这个方法,在dom处理上面用的较多。如果页面有多个input标签类型为checkbox,对于这时用$().each来处理多个checkbook,例如: $(“input[name=’ch’]”).each(function(i){ if($(this).attr(‘checked’)==true) { //一些操作代码 } 回调函数是可以传递参数,i就为遍历的索引。 对于遍历一个数组,用$.each()来处理,简直爽到了极点。例如: $.each([{“name”:”limeng”,”email”:”xfjylimeng”},{“name”:”hehe”,”email”:”xfjylimeng”},function(i,n) { alert(“索引:”+i,”对应值为:”+n.name); }); 参数i为遍历索引值,n为当前的遍历对象. var arr1 = [ “one”, “two”, “three”, “four”, “five” ]; $.each(arr1, function(){ alert(this); }); 输出:one two three four five var arr2

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 6 years ago . Very new to JQuery, and am struggling to understand .each(). I would like to be able to click on any heading, and have the paragraph under that heading appear, and then disappear. At the moment, I can only get the first paragraph to toggle. My code is: <script> $(document).ready(function(){ $("h2").click
