支持默认选项
你可以通过接受选项来自定义插件。
$.fn.colourize = function(options) {
// This is one method to support default options
var style = $.extend({
color: "green",
backgroundColor: "white"
}, options);
// Set the colours on the current selection based on the option parameters
return this.css({
color: style.color,
backgroundColor: style.backgroundColor
});
};
用法示例:
$("button").colourize({
color: "orange"
});
颜色选项绿色的默认值被 $.extend()
覆盖为橙色。
