I do not want to allow user to press order now until one of the field in catalog item is populated.
I am struggling in client script where I have to only allow users to press order now until few fields gets populated.
How can I do that?

@Taaha M 

there are 2 ways to handle this

1) you can use onSubmit catalog client script and check if that variable has value or not.

if not then stop form submission

function onSubmit(){
	if(g_form.getValue('variableName') == ''){
		g_form.addErrorMessage('Please fill the variable before submitting');
		return false;
	}
}

OR

2) You can mark that variable as mandatory always
