Form Validation

[NaniG]

Hi to all,

 

        If user has entered text in the text field with spaces (eg. user name), i have to show the error message and alert it, the text filed name should not contain the spaces. I used the basic javascript validation to validate the text filed... like

 

function validation()

{

    var txtfield1 = document.formx.txtfield1.value;

   

    if(txtfield1=="")

  {

      alert("Please enter txtfield1");

      document.formx.txtfield1.focus();

      return false;

  }

}

Need to alert the message when user entered with spaces.....

 

Please help me out...

 

Thanks in advance....

Use the JavaScript match method. Try

 

if(txtfield1.match(/ /g)) //g stands for global, means it will keep looking through entire string rather than stop at the first character if it returns false
   {
       alert('You entered a space.');
   }
else{
       //continue with function
   }

 

P.s. Please use code tags to display code. It's the button with a '#' on it.
