how to use encodeURI in form ?

how to use encodeURI in form ?
i want to send some chinese word to server without ?+parameter, how to use encodeURI in form send?

The form generates an inquiry form itself.
If you want to send inquiry yourself, make the following:

var data = myForm.getFormData() 

It will return you all form data to json format, then you can do the following:

dhtmlxAjax.post(url, params, callback)

thankyou
