I am trying to generate a random password ( this code’s running perfectly ),

  • 0

I am trying to generate a random password (this code’s running perfectly), which will be pasted to the value to the Password text box, but facing a problem while calling the javascript function.

Here is my JavaScript :

function password() {
    var chars =   "0123456789ABCDEFGHIJKLMNOPQRSTUVWXTZabcdefghiklmnopqrstuvwxyz";
    var string_length = 8;
    var randomstring = '';
    var table = document.getElementById('table'),
    rows = table.getElementsByTagName('tr'),
    i,j, cells, password;
    for (var i=0; i<string_length; i++) {
        var rnum = Math.floor(Math.random() * chars.length);
        randomstring += chars.substring(rnum,rnum+1);
    }
    for (i=0,j = rows.length; i<j;++i)
    {
    cells = rows[i].getElementsById('td');
    if(!cells.length)
    {continue;
    }
    password = cells[j].innerText;
    alert("hi "+password);
    }
    alert("Password is : "+randomstring);
    document.f2.password.value = randomstring;
}

Here is my Table :

<table name="table" id="table" cellpadding="4" cellspacing="2" border="1" bgcolor="" >
<tr name="tr" id="tr">
<th><input type="checkbox" name="allCheck" onclick="selectallMe()"></th>
<th>Emp ID</th>
<th>Device</th>
<th>Feature Status</th>
<th>Policy</th>
<th>Password Management</th>
</tr>
<tr>
<%  while(rs.next()){ %>
<td><input type="checkbox" name="chkName" onclick="selectall()"></td> 
<td><input type="text"  name="empId" value="<%= rs.getString(1)%> "   disabled="disabled"  maxlength="10"></td>
<td><input type="text" name="device" value="<%= rs.getString(2)%>"   disabled="disabled" maxlength="10"></td>
<td><input type="text"  name="features" value="<%= rs.getString(3)%>"  disabled="disabled" maxlength="60"></td>
<td><input type="text"  name="policyName" value="<%= rs.getString(4)%>"  disabled="disabled" maxlength="10"></td>
<td id="td" name="td"><input type="text" name="password" id="password" value=""  ><input type="button" name="Password" value="Password" onclick="password()"><input type="reset"  name="Reset" value="Rseset"></td>
</tr>
<% } 
%>
</table>

In my JS what is going wrong?? As I want to iterate through Password column, Password() will assign the value to the Password cells.

    i would prefer to put this in a comment but i don’t have the reputation to yet.

    first off is there a specific reason you want the cells to be text input types? Since you are just disabling them on creation.
    also look into the rows[index].cells(); and table.rows(); methods in JS. these will give you an array of the cells and rows. from there you can iterate to where you want.

    hope it helps
