Question

JS functions not responding.

Asked by: jchopra

It seems my javascript functions are not being able to get invoked. When i call a certain function on some user action it seems the control does not seem to go to the function. I confirmed this by putting an alert in first line of a function but that doesn't work either. What do u think i am possibly doing wrong. The way i call my function is :
<select size="1" NAME="status" VALUE="status" onChange="javascript: determineActiveStatus();" >

and the function itself is:
//This function disable and enable certain feilds when certain option is selected
function determineActiveStatus(){
alert('hello);
     switch(document.caseupdate.status.selectedIndex) {

              case 1:        document.caseupdate.pending.disabled = true;
                             document.caseupdate.reason.disabled = true;
                                    document.caseupdate.verbalreport.disabled = true;
                             break;
                                   
                 case 2:        document.caseupdate.pending.disabled = true;
                             document.caseupdate.reason.disabled = true;
                                    document.caseupdate.verbalreport.disabled = true;
                             break;


              default:       document.caseupdate.pending.disabled = false;
                              document.caseupdate.reason.disabled = false;
                                    document.caseupdate.verbalreport.disabled = false;
                             break;

         }

}

Its not giving me any error but neither it is working.
Please advice.

Put some options on your list. The "OnChange" event
isn't going to execute unless you can switch between
values on the list. (and your missing the closing quote
on your alert).

CPOsosky,

I don't exactly understand ur comment . Please elaborate.
Thanks for helping me.

 

by: jchopraPosted on 2003-02-18 at 10:02:57ID: 7975912

Oh i think now i got u. Yes i do have options in the list. It goes like this:
<select size="1" NAME="status" VALUE="status" onChange="javascript:determineActiveStatus();" >
          <option value?? selected></option>
          <option value="" >Final</option>
          <option value="">No Report</option>
          <option value="">Partial</option>
          </select>

Sorry for not being detailed.
Any suggestions now.

 

by: jchopraPosted on 2003-02-18 at 10:07:25ID: 7975939

This is the exact code. And what i want to do is that when i select any other option in the select box other than "Pending", the other 2 select box and input box should get disabled.

<SCRIPT LANGUAGE="JavaScript">
 //This function disable and enable certain feilds when certain option is selected
function determineActiveStatus(){
alert('hello);
     switch(document.caseupdate.status.selectedIndex) {

              case 1:        document.caseupdate.pending.disabled = true;
                             document.caseupdate.reason.disabled = true;
                                    document.caseupdate.verbalreport.disabled = true;
                             break;
                                   
                 case 2:        document.caseupdate.pending.disabled = true;
                             document.caseupdate.reason.disabled = true;
                                    document.caseupdate.verbalreport.disabled = true;
                             break;


              default:       document.caseupdate.pending.disabled = false;
                              document.caseupdate.reason.disabled = false;
                                    document.caseupdate.verbalreport.disabled = false;
                             break;

If I understood you correctly, your code seems to work.
When I select "partial" off the drop down, the input box
and the other 2 drop downs are disabled. Although the first
option on your drop down is blank, you have a couple of
question marks for the value. And your still missing the
closing quote on your alert, which will probably cause
an error when the page loads.

I figured out what is the problem. The cause of the problem was not this peice of code which i sent u. It is actually the foll. peice of code. This function is suppose to disable certain feilds when i check a particular radio button. But there is something wrong i am doing here. Can u help me with this one.
function deactivate(){
     alert('hello');
     if(document.caseupdate.video[1].checked==1){
          document.caseupdate.video[0].checked=0;
          document.caseupdate.timeIn.disabled = true;
          document.caseupdate.hours.disabled = true;
          document.caseupdate.mins.disabled = true;
          document.caseupdate.sec.disabled = true;
          break;
          }
}

 

by: CPOsoskyPosted on 2003-02-18 at 12:18:27ID: 7976841

Without the rest of the code, I need some more info.

Is it giving an error?
Does the alert message display?

You could put an alert inside the "if" statement to
make sure it's executing.

by: jchopraPosted on 2003-02-18 at 12:24:15ID: 7976883

I figured this one too. It's the 'break' that was giving problem.

How about another one:
If i have a text area and i want check that it is not empty when the user submits the form. How to do that.

 

by: CPOsoskyPosted on 2003-02-18 at 12:58:38ID: 7977132

Um, err...glad I could help :)

As for your next question...

You have to assign a function to the onSubmit event for your form.

Then do something like...

if(document.formname.textareaname.value == "")
   alert("Error");


-CPOsosky

 

by: jchopraPosted on 2003-02-18 at 13:04:42ID: 7977183

and how can i check if the user just pressed 'enter' in the text area and not actually entered any characters.
