Menu
Ok I have a list of check boxes. when a box is selected the value gets put into a text area. I aslso have a button to select all or deselect all check boxes. However I can’t get all the values from the checkboxes into the textarea when the “select all” button is clicked. any help would be greatly appreciated. here is what I have below:
<SCRIPT LANGUAGE=”JavaScript”>
function Doit()
{
myval=””
re=/,$/ // Use regular expression to remove comma from last value added to text box
for(i=0;i<myform.ckb.length;i++)
{
if(myform.ckb[i].checked)
{myval+=myform.ckb[i].value+”,”}
}
myform.txt1.value=myval.replace(re,””)
}
function setParentValue() {
//if (this.document.myform.txt1.value != null &&
//this.document.myform.txt1.value != “”) {
window.opener.document.forms[0].myTextBox.value +=
this.document.myform.txt1.value;
this.close();
//}
}
function checkAll(field)
{
var obj=document.all.ckb
for (i = 0; i < obj.length; i++)
obj.ckb[i].checked = true ;
}
function uncheckAll(field)
{
var obj=document.all.ckb
for (i = 0; i < obj.length; i++)
obj.ckb[i].checked = false ;
}
</script>
