  • easyui容易被忽略掉的部分

    官方文档有这么一段话:

    Each component of easyui has properties, methods and events. Users can extend them easily.

    Properties

    The properties is defined in jQuery.fn.{plugin}.defaults. For example, the dialog's properties is defined in jQuery.fn.dialog.defaults.

    Events

    The events(callback functions) is defined in jQuery.fn.{plugin}.defaults also.

    Methods

    The calling method syntax: $('selector').plugin('method', parameter);

    Where:

    • selector is the jquery object selector.
    • plugin is the plugin name.
    • method is the existing method corresponding to the plugin.
    • parameter is the parameter object, can be a object, string, ...

    The methods is defined in jQuery.fn.{plugin}.methods. Each method has two parameters: jq and param. The first parameter 'jq' is required, which refers to that jQuery object. The second parameter 'param' refers to the really parameter that pass through the method. For example, to extend a method named 'mymove' for the dialog component, the code looks like this:

    1. $.extend($.fn.dialog.methods, {
    2. mymove: function(jq, newposition){
    3. return jq.each(function(){
    4. $(this).dialog('move', newposition);
    5. });
    6. }
    7. });

    Now you can call 'mymove' method to move the dialog to specified position:

    1. $('#dd').dialog('mymove', {
    2. left: 200,
    3. top: 100
    4. });

    这段话其实描述了easyui使用的基本思路,以及扩展的思路。jQuery.fn.{plugin}.defaults,jQuery.fn.{plugin}.defaults,jQuery.fn.{plugin}.methods 分别是三部分的定义位置,可以对这三个定义分别扩展(添加和重写)。
