改成这样试一下看看呢？

var type =this.options.form.getWidgetByName("type").getValue()

var d = this.options.form.getWidgetByName("data_date");

var w = this.options.form.getWidgetByName("data_week");

if (type == "日") {

d.setVisible(true);

w.setVisible(false);

} else if(type == "周"){

d.setVisible(false);

w.setVisible(true);

} {

d.setVisible(false);

w.setVisible(false);

}

参考

或者试试这样

setTimeout(function() {

var type;

type = _g().getWidgetByName("type").getValue(); //获取报表主体控件的控件值

var d = this.options.form.getWidgetByName("data_date");

var w = this.options.form.getWidgetByName("data_week");

if (type == "日") {

d.setVisible(true);

w.setVisible(false);

} else if(type == "周"){

d.setVisible(false);

w.setVisible(true);

} {

d.setVisible(false);

w.setVisible(false);

}

}, 500)
