delay jquery uploadify process for certain period of time

In jquery uploadify plugin, after seleting multiple files ti upload, i want to put a condition for each file in the queue, and if that condition satisfy then only uploadi开发者_开发知识库ng process should continue. otherwise it should stop uploading files. How to check this conditions,

Please help me to get out of this problem

onComplete() will fire for each file upload event, and uploadifyClearQueue() will cancel the uploading process.

That won't delay the uploadify for a certain period of time as you put it in the title, but it will enable you to check for a condition and cancel the process if necessary.
