checking boxes

dazednconfused · July 10th, 2003, 04:09 AM

This is mostly javaScript code but because it is a php website thing I thought you guys may be able to help me. I cant find any good javaScript forms, so please have a look at it.

I am pulling severall rows out of a database and each of them have a checkbox, and I am trying to check them automatically when the page loads up.

function loadCheck3(rowID) {

if ("document.f"+rowID+".b"+rowID+".checked == false")

//alert("document.f"+rowID+".b"+rowID+".checked = true")
eval("document.f"+rowID+".b"+rowID+".checked = true");

}

I then call the function further down in the page for each row that is pulled from the database

><input type=\"checkbox\" value=\"CHECKED\" name=\"b".$row['id']."\" "?>
onMouseover="loadCheck3 (<? echo $row['id'];?>)"
<? echo " ></form>

It works because if I move the mouse over the box it checks it, my problem is is that I want it to check the box automatically when the page loads.

Anyone know how to do this?

I dont want to just write CHECKED in the input tags because i intend to develop this a little further.

I have tried onLoad but it doesnt work unless it is in the body tags

i haven't checked your code but this is how you can do it:

output your data to browser, make sure you include all <input type=checkbox> within one form for example <form name=myform></form>. then use the following code:

function setCheckedOnLoad() {

   //myform is the name of the form that includes all the checkboxes

   for(i=0;i<document.getElementById("myform").elemen ts.length;i++) {
      if(document.getElementById("myform").elements[i].type == "checkbox")
         document.getElementById("myform").checked = true;
   }
}

then invoke the function using onLoad event handler in <body>

<body onLoad="setCheckedOnLoad()">

peace
