按鼠标中键关闭标签

这一个demo使用了一些内置api,你需要查阅

js

// 提供鼠标中键关闭标签页,类似浏览器交互
BI.Plugin.registerObject("dec.workbench.tabs.button", function (widget) {
    //  绑定鼠标中键事件
    widget.element.mousedown(function (event) {
        if (event.button === 1) {
            //  调用tabPane api 关闭tab
            BI.Services.getService("dec.service.tabs").closeTab(widget.getValue());
        }
    });
});
