Check for Null Geomtry

[jayshukla]

Hi There, I am trying to do a query and check for a geometry that is not null, what is the best way to do this check. I tried to use x property and see if I could filter out value with Nan but this doesnt work.

Appreciate any feedback.

Thanks

shSrcLayer.queryFeatures(query, function (fs) {
    shSrcGLFS = fs;
    if (shSrcGLFS.features.length > 0) {
        shSrcGLgeom = shSrcGLFS.features[0].geometry;
        //alert("shSrcGLgeom: " + shSrcGLgeom.x + "," + shSrcGLgeom.y);
    }
});

var mp = new Multipoint(new SpatialReference({ wkid: 3857 }));

if (shSrcGLgeom .x !== 'NaN') {
    mp.addPoint(shSrcGLgeom );
}

See if isNan() javascript function works for you.

if (!isNaN(shSrcGLgeom.x)) {

//add point

}

I am using ExtJS API in my code. I am using Ext.isNumber() to check whether it's a number value.
