将chessbord.js与Flask集成 [英] Integrate chessbord.js with Flask

问题描述

我正在使用Flask，并且在使用 chessboard.js 时遇到问题。

我的静态文件夹是这样的：

  / static / 
 / css / 
 / img / 
 / js 
  

对于chessboard.js。

我的模板：

  {％extends base_templates / page_base.html％} {＃base_templates / page_base.html extends base_templates / base.html＃} 
 
 {％block main％} 
< h1>主页< H1> 
 
< p>任何使用者均可使用此页面。< / p> 
 
 {％if not current_user.is_authenticated（）％} 
< p> 
要查看会员页面，您必须
< a href ={{url_for（'user.login'）}}>登入< / a>或
< a href ={{url_for（'user.register'）}}>注册< / a> ;. 
< / p> 
 {％endif％} 
 
< p>代码：< / p> 
 
棋盘初始化为空白板，没有第二个参数。 
< / p> 
 
 <！ - 这里的棋盘代码：start example HTML ---> 
< div id =boardstyle =width：400px>< / div> 
 <！ -  end example HTML ---> 
 
< script type =text / javascriptsrc ='/ static / js / json3.min.js'>< / script> 
< script type =text / javascriptsrc ='/ static / js / jquery.min.js'>< / script> 
< script type =text / javascriptsrc ='/ static / js / chessboard.js'>< / script> 
< script> 
 
 var init = function（）{
 
 // ---开始示例JS --- 
 var board = new ChessBoard（'board'）; 
 // ---结束示例JS --- 
 
}; // end init（）
 $（document）.ready（init）; 
< / script> 
 {％endblock％} 
  

javascript找不到图片。它试图在/ img /不在/ static / img /上找到图像。如何解决这个问题？

解决方案

在 chessboard-0.3.0.js ，它说
$ b $ pre code cfg.pieceTheme ='img / chesspieces / wikipedia / {piece} .png';


如果您将其更改为：



  cfg.pieceTheme ='/static/img/chesspieces/wikipedia/{piece}.png'; 
  

能解决您的问题吗？你可能不得不使用确切的路径来反映你完整的目录结构（或使用相对路径），但这是需要改变的地方。


I'm working with Flask and I'm having problems using chessboard.js with it.

My static folder is something like this:

/static/
    /css/
    /img/
    /js

where I put the files for chessboard.js.

My template:

{% extends "base_templates/page_base.html" %}  {# base_templates/page_base.html extends base_templates/base.html #}

{% block main %}
<h1>Home page</h1>

<p>This page is accessible to any user.</p>

{% if not current_user.is_authenticated() %}
<p>
To view the Member page, you must
<a href="{{ url_for('user.login') }}">Sign in</a> or
<a href="{{ url_for('user.register') }}">Register</a>.
</p>
{% endif %}

<p>The code:</p>
<p>ChessBoard initializes to an empty board with no second argument.
</p>

<!-- Here the chessboard code: start example HTML --->
<div id="board" style="width: 400px"></div>
<!-- end example HTML --->

<script type="text/javascript" src='/static/js/json3.min.js'></script>
<script type="text/javascript" src='/static/js/jquery.min.js'></script>
<script type="text/javascript" src='/static/js/chessboard.js'></script>
<script>

var init = function() {

//--- start example JS ---
var board = new ChessBoard('board');
//--- end example JS ---

}; // end init()
$(document).ready(init);
</script>
{% endblock %}

The javascript can't find the images to show the board. It tries to find the images at /img/ not at /static/img/. How can I fix this?

解决方案

On line 445 of chessboard-0.3.0.js, it says

cfg.pieceTheme = 'img/chesspieces/wikipedia/{piece}.png';

If you change it to:

cfg.pieceTheme = '/static/img/chesspieces/wikipedia/{piece}.png';

does that fix your problem? You might have to play around with the exact path to reflect your complete directory structure (or use a relative path) but this is the place where it needs to be changed.
