問題描述

這個測試插件應該是這樣工作的:當一個元素被點擊時，它會向下移動.就那么簡單.

This test plugin, is supposed to work like this: When an element is clicked, it moves down. Simple as that.

jQuery.fn.moveDown = function(howMuch){
    $(this).css("border", "1px solid black");
    $(this).click(function(){

        $(this).css("position", "relative");
        $(this).animate({top: '+='+howMuch});
    }); 
}

問題是，當一個元素被點擊時，它不僅會移動被點擊的元素，還會移動應用插件的所有其他元素.

The problem is, when an element is clicked, it not only moves the clicked element but also ALL the other elements which the plugin was applied to.

解決辦法是什么?

推薦答案

對于插件創作嘗試這種方式，更可靠:

For plugin authoring try this way, much more solid:

這是 jsFiddle 示例.

插件:

(function($){
    $.fn.extend({
        YourPluginName: function(options) {
                var defaults = {
                      howMuch:'600',
                      animation: '',//users can set/change these values
                      speed: 444,
                      etc: ''
                }
        };

       options = $.extend(defaults, options);

       return this.each(function() {
          var $this = $(this);              
          var button = $('a', $this);// this represents all the 'a' selectors;
                                            // inside user's plugin definition.

          button.click(function() {
            $this.animate({'top':options.howMuch});//calls options howMuch value
          });
       });
})(jQuery);

用戶文件:

$(function() {
   $('#plugin').YourPluginName({
     howMuch:'1000' //you can give chance users to set their options for plugins
   });
});

<div id="plugin">
  <a>1</a>
  <a>2</a>
  <a>3</a>
</div>
