jQuery随机排序表行 [英] jQuery shuffle table rows
问题描述
我有一个包含三列的表:
I got a table with three columns:
1 A A
2 B B
3 C C
4 D D
1 A A
2 B B
3 C C
4 D D
我想做的是将表行改组,但仅将第二和第三列改组,就像下面的示例一样
What I want to do is to shuffle the table rows but only the second and third column, like the example below
1 C C
2 A A
3 D D
4 B B
1 C C
2 A A
3 D D
4 B B
我发现了一个漂亮的插件,它可以让表行被重新排列

I found a nifty plugin wich lets the table rows to be shuffled

但是我想保留第一列的默认顺序.
在改组后我将重新排列第一列,或者只是改组
第二和第三列.不管哪种方式,有人可以帮我解决这个问题吗?
but I want to keep the first column in it's default order.
Either I will reorder the first column after shuffling or I just shuffle
the second and third column. Either way can somebody help me out with this?

您在这里:
(function($){
//Shuffle all rows, while keeping the first column
//Requires: Shuffle
$.fn.shuffleRows = function(){
return this.each(function(){
var main = $(/table/i.test(this.tagName) ? this.tBodies[0] : this);
var firstElem = [], counter=0;
main.children().each(function(){
firstElem.push(this.firstChild);
});
main.shuffle();
main.children().each(function(){
this.insertBefore(firstElem[counter++], this.firstChild);
});
});
}
/* Shuffle is required */
$.fn.shuffle = function() {
return this.each(function(){
var items = $(this).children();
return (items.length)
? $(this).html($.shuffle(items))
: this;
});
}
$.shuffle = function(arr) {
for(
var j, x, i = arr.length; i;
j = parseInt(Math.random() * i),
x = arr[--i], arr[i] = arr[j], arr[j] = x
);
return arr;
}
})(jQuery)
用法
$("table").shuffleRows()
