一个接一个地改变多个div的颜色

问题描述：

我在逐个更改某些div的颜色时遇到问题. 在页面加载时，我创建了一个div，其中填充了一个15x15 div(class ='feld')的正方形

i have a problem changing the color of some divs one by one. on page load i create a div which is filled with a square of 15x15 divs (class='feld')

我要更改的所有div都有feld类

All the divs i want to change have the class feld

到目前为止，我的代码:

My code so far:

$(document).ready(function() {
create();
var delay = 1;
function create(){
    for (z = 1; z < 16; z++) {
            var zeile = jQuery('<div/>', {
                class: 'zeile',
                id: z,
                html: ""
            });
            $("#wortfeld").append(zeile);
            for (s = 1; s < 16; s++) {
            var div = jQuery('<div/>', {
                class: 'feld',
                id: s,
                html: ""
            });
            $(".zeile[id=" + z + "]").append(div);  
            };
        };
    };
$('.feld').each(function(){ 
        $(this).delay((delay++)*500).css("background-color","lightgoldenrodyellow");
    });
});

所以我的目的是一一改变每个.feld的颜色.但这并不能解决我的问题. 我也尝试过这种方式:

So my intention was to change the color of each .feld one by one. But it doesn't work the way i approached this. I also tried to do it this way:

    create(function(){
        $('.feld').each(function(){ 
            $(this).delay((delay++)*500).css("background-color","lightgoldenrodyellow");
    });
});

也不起作用

答

首先，这是一个不相关的问题，但可能会引起问题: 您不应该多次使用ID，并为您的zeile和feld项目提供唯一的ID. 您还可以使用setTimeout获得一些好处，而无需涉及.delay:

Firstly, an unrelated issue but one that could cause problems: You shouldn't use an ID more than once, give your zeile and feld items unique ID's. You could also get some mileage with setTimeout, no need to involve .delay:

$(document).ready(function() {
create();
var delay = 1;
function create(){
    for (z = 1; z < 16; z++) {
        var zeile = jQuery('<div/>', {
            class: 'zeile',
            id: 'z'+z,
            html: ""
        });
        $("#wortfeld").append(zeile);
        for (s = 1; s < 16; s++) {
        var div = jQuery('<div/>', {
            class: 'feld',
            id: 'z'+z+'s'+s,
            html: ""
        });
        $("#z" + z).append(div);  
        };
    };
};
    $('.feld').each(function(){
        setTimeout(function(x){
        $(x).css("background-color","lightgoldenrodyellow");
    },(delay++)*500,this);
    });
});
