构建 htmx 扩展

要定义扩展，请调用 htmx.defineExtension() 函数：

¥To define an extension you call the htmx.defineExtension() function:

<script>
  htmx.defineExtension('my-ext', {
    onEvent : function(name, evt) {
        console.log("Fired event: " + name, evt);
    }
  })
</script>

通常，这是在独立的 javascript 文件中完成的，而不是在内联 script 标记中完成的。

¥Typically, this is done in a stand-alone javascript file, rather than in an inline script tag.

扩展的名称应以破折号分隔，并且应简短且具有描述性。

¥Extensions should have names that are dash separated and that are reasonably short and descriptive.

扩展可以覆盖以下默认扩展点来添加或更改功能：

¥Extensions can override the following default extension points to add or change functionality:

{
    init: function(api) {return null;},
    getSelectors: function() {return null;},
    onEvent : function(name, evt) {return true;},
    transformResponse : function(text, xhr, elt) {return text;},
    isInlineSwap : function(swapStyle) {return false;},
    handleSwap : function(swapStyle, target, fragment, settleInfo) {return false;},
    encodeParameters : function(xhr, parameters, elt) {return null;}
}
