this.onmove.bind() is undefined

[lookfirst]

seeing this error on some devices (blackberry and sometimes mobile safari 4 and 5)...

TypeError: Result of expression 'this.onmove.bind' [undefined] is not a function.

can we just check to make sure it is defined?

I think it is undefined because Function.prototype.bind is not supported in ios safari < 6.0.

I didn't planned to support browsers without ECMAScript 5 support

Interesting... that explains a lot... no worries... I just have no control over who visits my site so I try to support them the best that I can...

I just changed the code to this:

if (this.onmove && this.onmove.bind) {
  this.onmove = this.onmove.bind(this);
  this.onend = this.hide.bind(this);
  this.bind();
}

You can use bind polyfill or ES5 shim

@andrepolischuk Good point, but the errors seem to be on devices where I just disable the magnifier anyway... =)

Can I close this?
