Question
Hi,
I have a query and i am really struggling with it. Below are the details
" In my cfm page I need to validate input fields before I submit my page, therefore i cannot keep the input type as submit for submit (as it will submit the page whatsoever). So i kept the type for submit as button and when it returns true I am redirecting to same page.
My problem is that when return is true I need to perform some action. i am just not getting how to do it:
My code is as below:
function funcSaveFinal()
{
  alert(funcSave());
  if(funcSave()==true)
     {
        var saveButton=document.getElementById('save');
        var saveAction=document.getElementById('saveAction1');   
        saveAction.value=saveButton.value;      
        alert(saveAction.value);
        <!---var SaveHolidayForm =document.getElementById("frmHolidayList");   
         SaveHolidayForm.action = "holidaylists.cfm";
           //alert(SaveHolidayForm.action)
         SaveHolidayForm.method = "post";
        SaveHolidayForm.submit();--->
        //saveAction.value=saveButton.value;
     }
}


<CFINPUT name="Save" type="button" value="Save"  id="save" onClick="funcSaveFinal();">


Please reply. I need help on this


Answer
Aloha,
Actually you DO want your action to be SUBMIT. The key is in the form tag you use onSubmit=somefunction()

<form name="myForm" action="someURL" onSubmit="validateme()">

The javascript must then do its thing and at the end have a return value of true or false depending on if you want the form to continue on to someURL

Take a look at this page http://www.w3schools.com/js/js_form_validation.asp

It gives a good example. There are plenty of other examples. Just search on javascript form validation

And your javascript seems flawed too. But that is another matter.
