one click two functions

[connieyongg]

Hi ,

could anybody pls advice how can i combine two actions with one single click, herein below are my sample code :

 <SCRIPT LANGUAGE="JavaScript"><!-- 
 
//function no-1
 
function codename() {
 
if(document.formname.checkboxname.checked)
{
document.formname.textname.disabled=false;
}
 
else
{
document.formname.textname.disabled=true;
}
}
 
//-->
 
 
//function - 2
 
function checkBox(id_sub, obj_check)
{
var Submit = document.getElementById(id_sub); 
 
if (obj_check.checked == true)
Submit.disabled = false;
else
Submit.disabled = true;
}
 
 
//function - 3
 
function basicFunctionBoth () {
codename();
checkBox('submit', this);
}
 
</script>
 
 
<form action="" method="" name="formname">
 
<input type="checkbox" onclick="basicFunctionBoth()" name="checkboxname" value="ON"> Do Both <br>
 
 
<br>
<input type="text" disabled size="10" name="textname">
<br><br>
<input type="submit" id="submit" value="Submit" disabled="disabled">
 
</form>
 

my problem is :
1) the function is work when it is revoke separately
2) when i combine these two with a single function name "basicFunctionBoth" , it does not work.


kindly advice. thank you in advance

In your function basicFunctionBoth(), 'this' is not the checkbox but the window object!
try
function basicFunctionBoth () {
codename();
checkBox('submit', document.formname.checkboxname);
}
It will work !
The better is to pass the chekbox as a parameter if you want to generalize this method!

Hi,

An alternative to that is to do:

<input type="checkbox" onclick="combined(this);">

...
function combined(checkboxObject) {
codename();
checkpoks('submit', checkboxObject);
}

Yes, that's what I was thinking at when I wrote

pass the chekbox as a parameter
