Styling the hint on a HTML5 input field using required attribute

由 六眼飞鱼酱① 提交于 2019-12-02 19:28:35
Is it possible to style the hint that appears on a HTML5 input field when using the required attribute. If you're not sure what I'm talking about click submit on this form without filling anything in. You should have a hint popup. http://24ways.org/examples/have-a-field-day-with-html5-forms/24ways-form.html I've checked the CSS source and couldn't see anything regarding the hint. I have found that styling the div element in a reset fashion affects how it appears. But I do not know how to target it specifically. Please note: I am NOT referring to a placeholder. Cheers, Thomas. The reason, why

C# Custom Attribute Required If

问题 I am just getting into custom attributes, and I absolutely love them. I am wondering if it is possible to create an attribute that gets applied to a property and denotes the name of another property in the same object. If would check to see if the referenced property has a value, and if so, the decorated attribute would be required. Something like this: [RequiredIfNotNull("ApprovedDate")] [DisplayName("Approved By")] [StringLength(50, ErrorMessage = "{0} must not exceed {1} characters")]

Perl: how to make variables from requiring script available in required script

example out.pl: (my|our|local|global|whatever???) var = "test"; require("inside.pm"); inside.pm: print $var; I don't want to use packages - it's overwhelming my needs :) thanks! It will work with our . $ cat out.pl our $var = "test"; require("inside.pm"); $ cat inside.pm print "Testing...\n"; print "$var\n"; $ perl out.pl Testing... test This works because our makes $var global, and inside.pm is being executed in the scope with $var defined. Not sure it is recommended technique, but it is an interesting question nevertheless! EDIT : Need to clarify (okay patch) the answer based on a comment:

Removing Required Attribute from Class but MVC3 still won't post the form without a value in the text box

由 孤街醉人 提交于 2019-12-01 00:28:51

I have deleted the "obj" folder, the "bin" folder, and also "Cleaned" the solutions. Still NO resolution. I don't want to do a stupid workaround,

@Autowired vs @Required on setter

由 房东的猫 提交于 2019-11-30 17:00:30
I'm curious to know what's the difference between code like this: class MyClass { @Autowired MyService myService; } and code like this: class MyClass { MyService myService; @Required public void setMyService(MyService val) { this.myService = val; } } Sudarshan_SMD @Autowired annotation is used when you want to autowire a bean. @Autowired is not limited to setter.
