使用jQuery动态安排div [英] Dynamically arranging divs using jQuery
问题描述
我有以下结构：
<div id="container">
<div id="someid1" style="float:right"></div>
<div id="someid2" style="float:right"></div>
<div id="someid3" style="float:right"></div>
<div id="someid4" style="float:right"></div>
</div>
现在someid实际上是该div的唯一ID。现在我收到一个有不同顺序的数组，比如说3,2,1,4，然后我如何使用jQuery移动这些div以匹配新订单？
Now someid is acually a unique id for that div. Now i receive an array which has a different order say someid 3,2,1,4, then how do i move these divs around to match the new order using jQuery?
非常感谢你的时间。

我的插件版本 - 工作演示
My plugin version - Working Demo
采用数组和可选的id前缀并重新排序其id对应的元素数组内的（id前缀）+值的顺序。数组中没有具有相应id的元素的任何值都将被忽略，并且将删除数组中没有id的所有子元素。
Takes an array and optional id prefix and reorders elements whose ids correspond to the order of (id prefix) + values inside the array. Any values in the array that don't have an element with the corresponding id will be ignored, and any child elements that do not have an id within the array will be removed.
(function($) {
$.fn.reOrder = function(array, prefix) {
return this.each(function() {
prefix = prefix || "";
if (array) {
for(var i=0; i < array.length; i++)
array[i] = $('#' + prefix + array[i]);
$(this).empty();
for(var i=0; i < array.length; i++)
$(this).append(array[i]);
}
});
}
})(jQuery);
演示代码
jQuery
$(function() {
$('#go').click(function() {
var order = $('#order').val() == ""? null: $('#order').val().split(",");
$('#container').reOrder(order, 'someid');
});
});
(function($) {
$.fn.reOrder = function(array, prefix) {
return this.each(function() {
prefix = prefix || "";
if (array) {
for(var i=0; i < array.length; i++)
array[i] = $('#' + prefix + array[i]);
$(this).empty();
for(var i=0; i < array.length; i++)
$(this).append(array[i]);
}
});
}
})(jQuery);
