Dear Experts,

I have a requirement, if the first field having validation error, then the system should not allow us to go to next field in the screen. the cursor position should be hold in the same field.

Please provide me the solution to achieve this, with Java Script/Ajax/JSF.

In my last query, experts are advised me to use PhaseListener, but it showing validation errors, but it is not restricting, it is allowing to go to next field.

kindly help me.

You only need javascript to do what you have requested. I'm not sure how exactly it would integrate into your code as I haven't seen it but generally you can check if the field has valid information in it after it loses focus which can easily be done in javascript and jquery and then if validation fails, force focus back to that field againg with javascript or jquery. I have a mini code snippet to show you how to do that in jquery

$("#yourField").focusout(function() {
//some validation code
if(!valid)
{
 //assuming valid is a boolean which is true if the data was valid
 $("#yourField").focus();
}
});

Open in new window


Let me know if you need help implementing this.
