void plus.runtime.openURL

用void plus.runtime.openURL为什么不能调起百度导航 能吊起高德
百度导航：void plus.runtime.openURL("http://api.map.baidu.com/direction?origin="+sessionStorage.yhlts+","+sessionStorage.yhlgs+"|name:我的位置&destination="+lglts[1]+","+lglts[0]+"&mode=driving&region="+citys+"&output=html");
高德导航：void plus.runtime.openURL('http://uri.amap.com/navigation?from='+curpo[0]+','+curpo[1]+',startpoint&to='+gopo[0]+','+gopo[1]+',endpoint&mode=car&policy=1&src=mypage&coordinate=gaode&callnative=0');
