Simple example program of validating form using onblur function Free porn girls chat up
Again, not very helpful, but it will stop people trying to input their email address or other such nonsense. Careful examination of the RFCs associated with email addresses has been conducted repeatedly and has been proven to require the use of recursion in order properly determine the validity of an email address using the full set of RFC specifications.
Here we are defining a My Custom Input template (but you can use the name you want) reimplementing the on Blur using our new handler which will take in input the current field store.
Different browsers may mark the input box in some way (Firefox 4 Beta adds a red box-shadow by default), display a warning (Opera) or even prevent the form from being submitted if this field has no value.
Hopefully these behaviours will converge in future releases.
I didnt realize this, so to answer your question I am not using any plugins.
I have a php validation function in hook_node_validate but it validates the whole form onsubmit.
