Does the mobile call Amap to set the zoom level invalid after search?

var map = new AMap.Map("allmap",{
    resizeEnable: true,
    zoom:13,
    center: [116.39,39.9]//new AMap.LngLat(116.39,39.9)
});
//
AMap.service(["AMap.PlaceSearch"], function() {
    var placeSearch = new AMap.PlaceSearch({ //
        map: map
    });
    //
    placeSearch.search(_SearchName);
});

after the mobile H5 page calls Amap, the zoom level zoom:13.
is set, but after the search instance is set, the zoom level will become invalid.
as shown in the figure:

what should be set for zooming to take effect?
