NS_ERROR_FAILURE for path.getTotalLength

Question

can you help me?

I make a loop on several "path" elements :

$.each($('path'), function(i, path){

var length = path.getTotalLength();

})

When the path is null (space character) I have this error on mozilla firefox :

NS_ERROR_FAILURE:
var length = path.getTotalLength();

I want to add a condition like this :

 $.each($('path'), function(i, path){

    if (path) {
    var length = path.getTotalLength();
    }

    })

But it doesn't work.

I fixed this recently in bug 1024860 . The fix will appear in Firefox 31. In the meantime you could wrap the call to check whether a path exists using element.hasAttribute() and then return 0.
