我想实现点击切换tab签传递不同的参数，请问js怎么写,下面是我写的一段js

var tabpane = this.getWidgetByName("TABPANE1");

switch(tabpane.mouseInTab){

case 0:

_g().getWidgetByName('chart6').gotoPage(1, {

"gnw": "国内","dw":"","xl":""

}, 'T');

_g().getWidgetByName('chart7').gotoPage(1, {

"gnw": "国内","dw":"","xl":""

}, 'T');

break;

case 1:

_g().getWidgetByName('chart6').gotoPage(1, {

"gnw": "国外","dw":"","xl":""

}, 'T');

_g().getWidgetByName('chart7').gotoPage(1, {

"gnw": "国外","dw":"","xl":""

}, 'T');

break;

default:

break;

}
