Checkbox's value is not passing correctly..

[abhi10kumar]

I am passing value to AJAX function, but always shows undefined..

It works fine two days ago, but not today..

 

Checkbox

<input type="checkbox" onclick="disablebatch(); selectinactivecourse(this.checked); " id="inactive_check" name="inactive_check" <?php if(isset($_POST['inactive_check'])) echo "checked";?>>

 

Combobox

<select id="course" name="course" style="width:145px" onchange="selectBatch1(this.value, document.myform.inactive_batch.value);"> // Where I am passing Checkbox's value

<select id="course" name="course" style="width:145px" onchange="selectBatch1(this.value, document.myform.inactive_batch.checked);"> // Also not working

function disablebatch()

{

if(document.myform.inactive_check.checked)

{

document.myform.inactive_batch.value=1;

document.myform.inactive_batch.disabled=true;

document.myform.batch.disabled=true;

alert(document.myform.inactive_batch.value);

}

else

{

document.myform.inactive_batch.value=0;

document.myform.inactive_batch.disabled=false;

document.myform.batch.disabled=false;

alert(document.myform.inactive_batch.value);

}

}

 

function selectBatch1(str, str1)

{

var v=str1; // str1 value is undefined

xmlhttp1=GetXmlHttpObject1();

if (xmlhttp1==null)

{

alert ("Your browser does not support AJAX!");

return;

}

var url="selectBatch.php";

url=url+"?c="+str;

url=url+"&action=misrpt";

if(v==undefined || v==true)

url=url+"&val=0";

else

url=url+"&val=1";

 

xmlhttp1.onreadystatechange=stateChanged1;

xmlhttp1.open("GET",url,true);

xmlhttp1.send(null);

}

Do inactive_check and inactive_batch refer to two different form fields? I can't tell if they're supposed to or not.

Um, you posted this:

 

<select id="course" name="course" style="width:145px" onchange="selectBatch1(this.value, document.myform.inactive_batch.value);"> // Where I am passing Checkbox's value

 

And that WOULD pass the value of the checkbox - if the checkbox actually had a value!

Checkbox

<input type="checkbox" onclick="disablebatch(); selectinactivecourse(this.checked); " id="inactive_check" name="inactive_check" <?php if(isset($_POST['inactive_check'])) echo "checked";?>>

There is no value parameter for that checkbox!!!

 

Looking at the function being called and how that "value" is used I think you meant to pass the checked state of the checkbox - not the value.

 

By the way, why would you pass a variable to a function as str1 only to then to use that value to define another variable "v"? If you want the value in the variable v, then just use that in the function parameters.
