JavaScript数组剪接 [英] JavaScript array splice
问题描述
您好计算器社区！
目前，我完全地卡住我的code，已尝试不同的方法采摘时要删除阵列的值，我知道我必须使用拼接它，但由于某种原因，它没有做什么，我想要它做
At the moment I am completly stuck with my code, have try different ways to remove a value from array when picked, I know I have to use splice for it, but for some reason it is not doing what I want it to do
由于网页是相当困难的，因为我的英语AINT说的好，我做它的一些截图来解释，我希望你能得到的想法，当你看到什么，我想做的事情！
Since the web page is quite difficult to explain as my english aint that good, I have made some screenshots of it, I hope you will get the idea when you see what I want to do!
这是用户将看到什么时，他访问网页，它是一个basicly游戏勒诺尔芒。用户不得不拖动3卡在下面的卡的灰色框。
This is what the user will see when he visit the webpage, it's basicly a lenormand game. the user has to drag 3 cards in to the gray box below the cards.
有一次，他已经拖3卡框，用户可以点击图像（卡）把他们（翻转）
Once he has dragged 3 cards to the box, the user can click on the images (Cards) to turn them (flip)
这工作得很好，唯一的问题是，我不希望用户选择相同的卡两次甚至三次，因为我做了数组，我想我应该用拼接的功能，但到目前为止，没有结果！
This works fine, the only problem is that I don't want the user to pick the same cards twice of even three times, Since I do this with a array, I thought I should use Splice function, but so far, no result!
对于JavaScript的code，这里是
for the JavaScript code, here is the JSFiddle http://jsfiddle.net/dkk2nqyg/
这里的某个地方，我必须补充拼接
Somewhere here, I must add the splice
$(function () {
var cars = ["2", "3", "5", "6", "7", "8", "9", "10", "11", "12", "13", "14", "15", "16", "17", "18", "19", "20", "21", "22", "23", "24", "25", "26", "4"];
var rand = cars[Math.floor(Math.random()*cars.length)];
$(".cards img").each(function(index) {
$(this).wrap('<div class="front"></div>')
.parent().wrap('<div class="flipper"></div>')
.parent().wrap('<div class="flip-container"></div>')
.append('<div class="back"><img src="./kaart/'+cars[Math.floor(Math.random()*cars.length)]+'.png"</img> </div>');
});
我已经try'd许多解决方案，但问题是，我需要在这里拼接它，ATLEAST，我想：
I have try'd many solutions, but the problem is that I need to splice it here, atleast, I think:
.append('<div class="back"><img src="./kaart/'+cars[Math.floor(Math.random()*cars.length)]+'.png"</img> </div>');
我会很高兴有这个问题解决了，我希望计算器可以提供我的帮助我想：）
I would gladly have this issue resolved and I hope StackOverflow can offer me the help I want :)
谢谢！
推荐答案
您可以使用拼接（）来删除该数组中的项，因为剪接返回一个数组，然后您可以在索引0在访问该元素，以获得牵强的src值
You can use splice() to remove an item from the array, since splice returns an array then you can access the element at the index 0 to get the fetched src value
'<div class="back"><img src="./kaart/' + cars.splice(Math.floor(Math.random() * cars.length),1)[0] + '.png"</img> </div>'
