JS脚本修改控件时间问题！

我的想法是通过JS脚本来实现控件日期和时间，但增加了CONCATENATE函数之后无效！但是我单独使用是没有问题的！

例：var data = this.getValue(); //获取当前值
var AA = '${=CONCATENATE(dateInWeek(TODATE(),1)," 00:00:00")}'; //获取本周开始日期
var AB = '${=CONCATENATE(dateInWeek(TODATE(),-1)," 23:59:59")}'; //获取本周结束日期
var AC = '${=CONCATENATE(DATEINMONTH(TODATE(),1)," 00:00:00")}'; //获取本月开始日期
var AD = '${=CONCATENATE(DATEINMONTH(TODATE(),-1)," 23:59:59")}'; //获取本月结束日期
var AE = '${=CONCATENATE(DATEINYEAR(TODATE(),1)," 00:00:00")}'; //获取本年开始日期
var AF = '${=CONCATENATE(DATEINYEAR(TODATE(),-1)," 23:59:59")}'; //获取本年结束日期
var AG = '${=CONCATENATE(DATEINQUARTER(TODAY(),1)," 00:00:00")}'; //获取本季开始日期
var AH = '${=CONCATENATE(DATEINQUARTER(TODAY(),-1)," 23:59:59")}'; //获取本季结束日期
var state1 = this.options.form.getWidgetByName("ksrq");
var state2 = this.options.form.getWidgetByName("jsrq");
if(data == "本周") {
state1.setValue(AA);
state2.setValue(AB);
} else if(data == "本月") {
state1.setValue(AC);
state2.setValue(AD);
} else if(data == "本季度") {
state1.setValue(AG);
state2.setValue(AH);
} else if(data == "本年") {
state1.setValue(AE);
state2.setValue(AF);
}
