Javascript check based on two elements...

[themissingelf]

What is wrong with this code? I'm relatively new to Javascript, therefore, not very good at spotting why it does not work at times. Very grateful for any help.

I have a checkbox that, when checked, has a value of "Yes". If checked and form field "_013_currsite" is blank I want a prompt box to appear asking for "...current web site". I then want to assign the value of the prompt field to "_013_currsite".

In the checkbox input I have an onBlur event calling wwwPrompt.

At the moment, the onBlur calls the function. The value entered in the prompt assigns to "_013_currsite"; however, what the function does not seem to spot is when there is an entry in "_013_currsite" already (in which case I do not want the prompt to appear).

Any idea what's occuring here?

function wwwPrompt(enquiryForm) {
    if (enquiryForm._016_review_site.value=="Yes" && enquiryForm._013_currsite.value=="");
var www = prompt("Please enter your current web site address.",""); {
    enquiryForm._013_currsite.value=www; return false;
    }
enquiryForm._017_site_hosting.focus(); return true;
}

This is always true:

enquiryForm._016_review_site.value=="Yes"

This can be true or false:

enquiryForm._016_review_site.checked

Thanks jofa, however, I changed the script to:

function wwwPrompt(enquiryForm) {
    if (enquiryForm._016_review_site.checked && enquiryForm._013_currsite.value=="");
var www = prompt("Please enter your current web site address.",""); {
    enquiryForm._013_currsite.value=www; return false;
    }
enquiryForm._017_site_hosting.focus(); return true;
} 

...but the prompt box appears regardless of whether the box is checked or not (i.e. if I use tab to go through the fields on the form, as soon as _016_review_site onBlur, the prompt appears).

Not sure where to go from here. Any further thoughts?

Remove the semicolon after if(...)

function wwwPrompt(enquiryForm) 
{
  if(enquiryForm._016_review_site.checked && enquiryForm._013_currsite.value=="")
  {
    var www = prompt("Please enter your current web site address.",""); 
    enquiryForm._013_currsite.value=www; 
    return false;
  }
  enquiryForm._017_site_hosting.focus(); 
  return true;
}

Excellent, thank you.
