object expected error in IE8

[neha thakur]

I am getting an error object expected in IE8 for following code. Could anybody help?

$(function() {
$('.password').pstrength();
});

This is the highlighted code out of the following code.

<script type="text/javascript">
$(function() {
$('.password').pstrength();
});
checked=false;
function checkedAll (myform) { 
var aa= document.getElementById('myform');
if (checked == false)
{
   checked = true
}
else
{
   checked = false
}
for (var i =0; i<aa.elements.length; i++) 
{
 aa.elements[i].checked = checked;
}
}
 
function check_emailid(){
if (trim(document.add_emailid.subject.value) == "")
{
    alert ("Plese subject name.");
    return false;
}
if(trim(document.add_emailid.mail_id.value)!="")
{
   var reg = /^([A-Za-z0-9_\-\.])+\@([A-Za-z0-9_\-\.])+\.([A-Za-z]{2,4})$/;
   var address = document.add_emailid.mail_id.value;
   if(reg.test(address) == false) {
    alert('Invalid Email Address');
  return false;
     }
}
}
function trim(str) { 
    if (str != null) {
        var i; 
        for (i=0; i<str.length; i++) {
            if (str.charAt(i)!=" ") {
                str=str.substring(i,str.length); 
                break;
            } 
        } 
 
        for (i=str.length-1; i>=0; i--) {
            if (str.charAt(i)!=" ") {
                str=str.substring(0,i+1); 
                break;
            } 
        } 
 
        if (str.charAt(0)==" ") {
            return ""; 
        } else {
            return str; 
        }
    }
}
 
</script>

I assume this is a plugin that you're using. Have you followed the instructions for installation/setup?
