Rangeslider.js |(Rangeslider.js | Uncaught TypeError: Cannot read property '0' of undefined)

我正在尝试使用rangeslider.js

这是我的HTML包括：

这是我的HTML：

<input type="range" min="0.0" max="1.0" step="0.05" value="0.8" data-rangeslider="" style="position: absolute; width: 1px; height: 1px; overflow: hidden; opacity: 0;"> <script> // Initialize a new plugin instance for all // e.g. $('input[type="range"]') elements. $('input[type="range"]').rangeslider(); // Destroy all plugin instances created from the // e.g. $('input[type="range"]') elements. $('input[type="range"]').rangeslider('destroy'); // Update all rangeslider instances for all // e.g. $('input[type="range"]') elements. // Usefull if you changed some attributes e.g. `min` or `max` etc. $('input[type="range"]').rangeslider('update', true); </script>

我得到这个错误：

Uncaught TypeError: Cannot read property '0' of undefined.

这些是在rangeslider.min.js中引用的rangeslider.min.js ：

line 169: this.handleDimension = g(this.$handle[0], "offset" + i(this.DIMENSION)), line 272: "string" == typeof b && e[b].apply(e, c)

我不确定我正在造成什么类型的错误？

I'm trying to use rangeslider.js

This is my HTML includes:

This is my HTML:

I am getting this error:

Uncaught TypeError: Cannot read property '0' of undefined.

These are the lines that appear to be being referencing to in rangeslider.min.js:

line 169: this.handleDimension = g(this.$handle[0], "offset" + i(this.DIMENSION)), line 272: "string" == typeof b && e[b].apply(e, c)

I am unsure as to what type error I am causing?

最满意答案

您需要包含rangeslider.js的css文件，并且您不应该销毁rangeslider。

举个最简单的例子：

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8">
    <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/rangeslider.js/2.3.2/rangeslider.css">
</head>
<body>
    <input type="range" min="10" max="1000" step="10" value="300">
    <script src="https://code.jquery.com/jquery-3.0.0.min.js"></script>
    <script src="https://cdnjs.cloudflare.com/ajax/libs/rangeslider.js/2.3.2/rangeslider.js"></script>
    <script>
       $('input[type="range"]').rangeslider({polyfill: false});
    </script>
</body>
</html> 
  
 
 
 上面的例子基于rangeslider.js中的代码。  
 我认为rangeslider.js中的Usage部分只是一个脚本展示。 所以如果我们直接使用这些脚本，会发生以下错误：  
 Chrome中的错误消息：  
 
  Uncaught TypeError：无法读取未定义的属性'0'  
 
 Firefox中的错误消息：  
 
  TypeError：这个。$ handle是未定义的  
You need to include the css file of rangeslider.js, and you shouldn't destroy the rangeslider. 
For a minimun example: 
 
 
  
  <!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8">
    <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/rangeslider.js/2.3.2/rangeslider.css">
</head>
<body>
    <input type="range" min="10" max="1000" step="10" value="300">
    <script src="https://code.jquery.com/jquery-3.0.0.min.js"></script>
    <script src="https://cdnjs.cloudflare.com/ajax/libs/rangeslider.js/2.3.2/rangeslider.js"></script>
    <script>
       $('input[type="range"]').rangeslider({polyfill: false});
    </script>
</body>
</html> 
  
 
 
The example above is based on the code in rangeslider.js. 
I think the Usage section in rangeslider.js is just a script showcase. So if we directly use those scripts, the following errors occurs: 
Error message in chrome: 
 
 Uncaught TypeError: Cannot read property '0' of undefined 
 
Error message in Firefox: 
 
 TypeError: this.$handle is undefined
