问题描述

这是我的小提琴 https://jsfiddle.net/tuc1faug/1/
在这里,我已经使用jQuery分配了具有特定值的颜色。
颜色每次都会被洗牌。现在,我希望这些值能够隐藏在单元格中,并且我希望所有这些值都以该洗牌顺序存储到数组中。
Html:

Here's my fiddle https://jsfiddle.net/tuc1faug/1/ Here I have assigned the colors with the specific values using jquery. Colors will be shuffled each time.Now i want these values to be hidden in the cells and I want all those values to be stored into an array in that shuffled order Html:

<table  border="5px" width="500px" height="50px" align="center">
    <tr id="colors">
        <td height="50px" orderId="1" bgcolor="red"></td>
        <td height="50px" orderId="6" bgcolor="brown"></td>

        <td height="50px" orderId="5" bgcolor="pink" ></td>
        <td height="50px" orderId="0" bgcolor="blue" ></td>

        <td height="50px" orderId="7" bgcolor="black"></td>
        <td height="50px" orderId="2" bgcolor="green"></td>

        <td height="50px" orderId="4" bgcolor="orange" ></td>
        <td height="50px" orderId="3" bgcolor="yellow"></td>
    </tr>  
</table>

jQuery:

var arr=[];
var colorCells =document.getElementById('colors').getElementsByTagName('td');
var colors = ["blue","red","green","yellow","orange","pink","brown","black"];
for(var i = 0; i < colorCells.length; i++)  {
    $(colorCells[i]).attr("bgColor", colors.splice(Math.random() * (colors.length),1)) ;
    arr.push(colorCells[i].style.backgroundColor);
}

var colorValues = {"red": 2, "blue":3, "green": 4, "yellow":"1", "orange":5, "black":1, "brown":6, "pink":5};
$("table td").each(function() {
    $(this).html(colorValues[$(this).attr("bgColor")]);
});


推荐答案

我编辑了你的函数。如果我能够正确理解你的问题,那么你需要颜色的随机数字应该存储在数组中,并且你应该隐藏显示的数字。

I have edited your function. If I am understood your question correctly, you need random numbers for color should be stored in array and you should hide numbers from display.

如果所以,下面是代码

$(function() {
    var arr=[];
    // New array for adding the color number
    var colorNumber = [];
    var colorCells =document.getElementById('colors').getElementsByTagName('td');
    var colors = ["blue","red","green","yellow","orange","pink","brown","black"];
        for(var i = 0; i < colorCells.length; i++)  {
                var randomColor = Math.random() * (colors.length);
            $(colorCells[i]).attr("bgColor", colors.splice(Math.random() * (colors.length),1)) ;
            arr.push(colorCells[i].style.backgroundColor);
        }

        var colorValues = {"red": 2, "blue":3, "green": 4, "yellow": 7, "orange":5, "black":1, "brown":6, "pink":8};
        $("table td").each(function() {
            // Get the color value from the array and add it in colour numbers array.
            colorNumber.push(colorValues[$(this).attr("bgColor")]);

            // Hide it from display.
            //$(this).html(colorValues[$(this).attr("bgColor")]);   
        });

        // Your colorNumber array.
        alert(colorNumber);
 });
