jQuery空间验证

Question

I am using Jquery custom validation for no space.

jQuery.validator.addMethod("noSpace", function(value, element) { 
      return value.indexOf(" ") < 0 ; 
});

And its working fine. But it also fire validation when I used space between the word like "Test Example".

Example 1 :: " " //Validation (Its fine.) Example 2 :: "Test Example" //Validation (I dont want validation in it.)

Basically I don't want a space in a starting but requrired space between the word.

Answer 1

I think you can use trim(). I'm not pretty sure about the validator, but you can try this:

jQuery.validator.addMethod("noSpace", function(value, element) { 
      return (value.trim() == value) && (value.indexOf(" ") > 0);
});

Edit: the correct answer:

jQuery.validator.addMethod("noSpace", function(value, element) { 
      return (value.trim() == value) && (value.indexOf(" ") < 0); 
})
