我正在尝试在回调中保留this
变量:
var that = this
// type1
bootbox.confirm("This is the default confirm!", function(result){
console.log(that.whatever);
});
// type2
bootbox.confirm({
message: "This is a confirm with custom button text and color! Do you like it?",
callback: function (result) {
console.log(that.whatever);
}
});
它看起来很丑,还有更好的方法吗?
答案 0 :(得分:1)
您可以使用箭头功能:
bootbox.confirm("This is the default confirm!", result => {
console.log(this.whatever);
});
不过,您应该使用Babel进行编译,older browsers may not support it。如果您将回调作为变量,则可以在传递之前将其绑定:
yourCb.bind(this);
bootbox.confirm("This is the default confirm!", yourCb);
