aui-dialog改造，支持关闭

1.打开aui-dialog.js

添加关闭html代码

var headerHtml = params.title ? '<div class="aui-dialog-header ddd-dialog-header">' + params.title + '<span style="position:absolute;top:0.1rem;right:0.2rem;"><i class="aui-iconfont aui-icon-close ddd-icon-close aui-dialog-close"></i></span></div>' : '<div class="aui-dialog-header ddd-dialog-header">' + self.params.title + '<span style="position:absolute;top:0.1rem;right:0.2rem;"><i class="aui-iconfont aui-icon-close ddd-icon-close aui-dialog-close"></i></span></div>';

2.给关闭按钮赋予事件

var dialogCloseButtons = document.querySelectorAll(".aui-dialog-close");
if (dialogCloseButtons && dialogCloseButtons.length > 0) {
for(var ii = 0; ii < dialogCloseButtons.length; ii++){
dialogCloseButtons[ii].onclick = function(){
self.close();
return;
}
}
}

检测包含aui-dialog-close的元素，添加onclick事件，点击后，关闭窗口。

方法论:

掌握js的本质，才能灵活的改造插件。
