javascript – Mousemove回调事件没有显示哪个鼠标按钮被按下safari

我正在开发一个HTML5播放器.
它在所有浏览器上运行正常,除了osx的safari. (此播放器应该仅适用于桌面浏览器).

我有一个搜索栏和音量栏的问题.

基本上它是一个滑块,但用div和东西实现.我做了以下.

在’mousemove’事件的元素上注册了一个回调.
触发此回调时,我会检查事件是否有按钮.
使用safari时,此属性始终为“未定义”.

代码很简单：

this.controls.$seekBar.on('mousemove',(function(_this){
            return function(event){
                if (event.buttons == 1) {
                    // Do some stuff
                }
            }
        })(this))
            .on('mousedown',(function(_this){
                return function(event){
                    if (event.buttons == 1) {
                        // Do some stuff
                    }
                }
            })(this));

由于它是一个jQuery插件,我需要使用闭包将插件上下文传递给回调,但这不是问题.我测试不是一个jQuery插件,同样的错误发生.

最佳答案

你可以简单地修改你的代码,如下所示：

   this.controls.$seekBar.on('mousemove',(function(_this){
        return function(event){
            var buttons = (e.buttons === undefined ? e.which : e.buttons);
            if (buttons == 1) {
                // Do some stuff
            }
        }
    })(this))
        .on('mousedown',(function(_this){
            return function(event){
                var buttons = (e.buttons === undefined ? e.which : e.buttons);
                if (event.buttons == 1) {
                    // Do some stuff
                }
            }
        })(this));

它适用于您需要的所有浏览器.
