我试图在一个简单的 jquery 插件中调用一个函数。我看到 init 方法将宽度增加了 30 但 add50 方法抛出了错误Uncaught TypeError: Object [object Object] has no method 'add50'
。不确定是什么导致此错误发生。
jsfiddle:http: //jsfiddle.net/nsshrinivasan/KnDMq/6/
;(function ( $, window, document, undefined ) {
// Create the defaults once
var pluginName = 'Extender',
defaults = {
propertyName: "value"
};
// The actual plugin constructor
function Plugin( element, options ) {
this.element = element;
this.options = $.extend( {}, defaults, options) ;
this._defaults = defaults;
this._name = pluginName;
this.init(this.element);
}
Plugin.prototype = {
init : function (element) {
// console.log($(this.element).width());
$(element).width($(element).width() + 30);
},
add50 : function(element){
$(element).width($(element).width() + 50);
}
};
$.fn[pluginName] = function ( options ) {
return this.each(function () {
if (!$.data(this, 'plugin_' + pluginName)) {
$.data(this, 'plugin_' + pluginName,
new Plugin( this, options ));
}
});
}
})( jQuery, window, document );
$('#metal').Extender().add50();
HTML:
<div id='metal'></div>
CSS:
#metal{
width: 50px;
height: 10px;
background:red;
}
