I got this code for disabling the fields depening on what "ploeg" is selected.

When i start the page, nothing is disabled, changing the selection doesnt make it work also.

 

My code for the selection "ploeg" =

Ploeg : <select name="ploeg" size="1" onchange="checkploeg();">
<option value="vroeg" selected="selected">Vroege ploeg</option>
<option value="laat" onchange="return checkploeg();">Late ploeg</option>
<option value="nacht" onchange="return checkploeg();">Nacht ploeg</option>
</select>

 

the javascript function that is called is this one =

function checkploeg(){
			var ploeg = document.forms[0].ploeg.options[document.forms[0].ploeg.selectedIndex].text;
			if(ploeg == "vroeg"){
				document.forms[0].EF1.disabled="false";

The problem is that you are setting the disabled state to the STRING values "true" or "false" not the boolean values of true and false.

 

Incorrect:

document.forms[0].EF1.disabled="false";

 

Correct:

document.forms[0].EF1.disabled=false;

 

Also, you can cut down the amount of code needed a great deal with a little more logic. It appears than many "sections" are either being enabled or disabled completely. You could simply create a function to enable/diable those sections and call them accordingly.

 

function disableBlock2(disableBool)
{
    document.forms[0].B1A.disabled =disableBool;
    document.forms[0].B1B.disabled =disableBool;
    document.forms[0].B2A.disabled =disableBool;
    document.forms[0].B2B.disabled =disableBool;
    document.forms[0].uB1A.disabled=disableBool;
    document.forms[0].uB1B.disabled=disableBool;
    document.forms[0].uB2A.disabled=disableBool;
    document.forms[0].uB2B.disabled=disableBool;
}

function disableBlock4(disableBool)
{
    document.forms[0].osmoseV.disabled=disableBool;
    document.forms[0].cediV.disabled  =disableBool;
    document.forms[0].vf1V.disabled   =disableBool;
    document.forms[0].vf2V.disabled   =disableBool;
    document.forms[0].vf3V.disabled   =disableBool;
    document.forms[0].vf4V.disabled   =disableBool;  
    document.forms[0].vf8V.disabled   =disableBool;
    document.forms[0].vf10V.disabled  =disableBool;
    document.forms[0].vf9V.disabled   =disableBool;
    document.forms[0].vf11V.disabled  =disableBool;
}

function disableBlock5(disableBool)
{
    document.forms[0].osmoseL.disabled=disableBool;
    document.forms[0].cediL.disabled  =disableBool;
    document.forms[0].vf1L.disabled   =disableBool;
    document.forms[0].vf2L.disabled   =disableBool;
    document.forms[0].vf3L.disabled   =disableBool;
    document.forms[0].vf4L.disabled   =disableBool;
    document.forms[0].vf8L.disabled   =disableBool;
    document.forms[0].vf10L.disabled  =disableBool;
    document.forms[0].vf9L.disabled   =disableBool;
    document.forms[0].vf11L.disabled  =disableBool;
}

function disableBlock6(disableBool)

Change:

var ploeg = document.forms[0].ploeg.options[document.forms[0].ploeg.selectedIndex].text;

 

To:

var ploeg = document.forms[0].ploeg.options[document.forms[0].ploeg.selectedIndex].value;

 

That indeed did the trick  ;D

Thing is I used the text option to put the text in a string for database storage.

Both thx for ur help !
