问题 Is there a way to break out of a <g:each>? I have a page wherein I'm iterating through a list and I have to make sure that a checkbox is checked if that was the value stored in DB. To make it a little clearer, please consider something like: <g:each in=${list1}> <g:each in=${list2}> <g:if test="${list1.id == list2.id}"> <input type="checkbox" ... checked="checked" /> </if> </g:each> ... </g:each> where list1 is, say Domain1.list() (i.e. ALL possible values) and list2 is Domain2.find(...)

【(重点)数组循环遍历的四种方式】 1，https://www.cnblogs.com/waj6511988/p/6927208.html 2，https://www.cnblogs.com/muziyun1992/p/6723958.html 1、使用for循环遍历数组 conut($arr);用于统计数组元素的个数。 for循环只能用于遍历，纯索引数组！！！！ 如果存在关联数组，count统计时会统计两种数组的总个数，使用for循环遍历混合数组，导致数组越界！！ eg： $arr = array(1,2,3,5,6,7); $num = count($arr); //count最好放到for外面，可以让函数只执行一次 count统计数组中元素的个数。 echo "数组元素的个数 {$num} <br/>"; //注意这里典型的 双引号内用花括号包裹变量 for($i=0;$i<$num;$i++){ echo " {$i} ==> {$arr[$i]} <br/>"; //注意php中双引号内使用花括号包裹变量的写法 } 2、forEach循环遍历数组 foreach可以遍历任何类型的数组！！！ eg： $arr = array(1,2,3,"one"=>4,5,6,7); foreach($arr as $value){ echo "{$value}<br>"; }

Jquery中each的三种遍历方法

1、选择器+遍历 $('div').each(function (i){ i就是索引值 this 表示获取遍历每一个dom对象 }); 2、选择器+遍历 $('div').each(function (index,domEle){ index就是索引值 domEle 表示获取遍历每一个dom对象 }); 3、更适用的遍历方法 1）先获取某个集合对象 2）遍历集合对象的每一个元素 var d=$("div"); $.each(d,function (index,domEle){ d是要遍历的集合 index就是索引值 domEle 表示获取遍历每一个dom对 }); 案例： <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>属性选择器学习</title> <script language="javascript" type="text

Javascript - Making Array Index toLowerCase() not working

由 余生长醉 提交于 2019-12-31 04:00:09
问题 I'm trying to make all array indexes lowercase strings, but it's not working. I looked at other answers on here and tried their solutions like using toString() before adding toLowerCase but it doesn't work, which is weird. I created a jsfiddle of the problem here. JS: $(colorArr).each(function(i, item) // loop thru each of elements in colorArr and make lowercase + trim { if(colorArr[i] !== undefined) // check if colorArr index undefined { colorArr[i].toString().toLowerCase().trim(); // FIX

问题 I'm using Jquery mobile, so ignore some of the following overdone css, its not related to the core issue. I'm having a problem looping over the "Places" in my JSON packet/javascript object.

I've tried different variations & searching everywhere but no luck. i = 1; var timer = new Array(); jQuery('a').each(function($) { i++; timer[i] = setTimeout(jQuery(this).remove(), i * 5000) }) 回答1: Wrap remove element with a function i = 1; var timer = new Array(); jQuery('a').each(function($) { i++; var thiz = jQuery(this); timer[i] = setTimeout(function() { thiz.remove(); }, i * 5000); }) 回答2: The first parameter to setTimeout (or setInterval )
