创建< div>使用JQuery for循环的网格 [英] Creating <div> grid with JQuery for loop
问题描述
我是网络开发新手，但具有非常稳定的编程背景。我已经尝试了多种方式基于用户输入以编程方式创建元素。我尝试通过JQuery创建网格。
I'm new to web development but have a pretty solid programming background. I've tried multiple ways to create a element programatically based on user input. I'm trying to essentially create a grid through JQuery.
我通过将用户输入存储到变量并通过for循环创建格。这里是.js文件的代码：
I'm tackling this problem by storing the user input into a variable and going through a for loop to create the grid. Here is the code for the .js file:
var rows = 8;
var columns = 8;
var $row = $("<div />", {class: 'row'});
var $square = $("<div />", {class: 'square'});
$(document).ready(function(){
for(var i = 0; i < rows; i++){
$("#wrapper").append($row);
}
for(var i = 0; i < columns; i++){
$(".row").append($square);
}
});
现在由于某种原因，这段代码只在#wrapper中创建一行，在行中创建一个正方形。我试图复制解决这个问题的示例CSS文件，但似乎没有任何工作。这是我现在的CSS：
Now for some reason, this code only creates one row in #wrapper and one square in the row. I've tried copying the example CSS files that tackle this problem but nothing seems to work. Here's what I have right now for my CSS:
#wrapper {
width: 850px;
height: 850px;
margin-top: 100px;
margin-left: auto;
margin-right: auto;
background: #000000;
}
.row {
width: auto;
height: 100px;
background: #313131;
}
.square {
width: 100px;
height: 100px;
margin: 0px;
outline: 1px solid;
display: inline-block;
float: left;
background: #FFFFFF;
}
以下是我的HTML：
And here's my HTML:
<!doctype html>
<html>
<head>
<title>Draw Grid</title>
<link rel="stylesheet" type="text/css" href="theme.css" >
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<script src="draw.js"></script>
</head>
<body>
<div id="wrapper">
</div>
</body>
</html>
任何人都可以帮我吗？我很困惑。我已经尝试了一切。这是一个CSS格式化错误？
Can anybody help me out? I'm so confused. I've tried everything. Is this a CSS formatting error?
推荐答案
问题是你只创建一个行和方形对象，你需要使用克隆副本，他们只是复制
The problem is you are creating only one row and square objects, you need to use cloned copies else they are just copy
var rows = 8;
var columns = 8;
var $row = $("<div />", {
class: 'row'
});
var $square = $("<div />", {
class: 'square'
});
$(document).ready(function () {
//add columns to the the temp row object
for (var i = 0; i < columns; i++) {
$row.append($square.clone());
}
//clone the temp row object with the columns to the wrapper
for (var i = 0; i < rows; i++) {
$("#wrapper").append($row.clone());
}
});
