Question

my el6.href and el7.href doesn’t work,

if I place el6.href and el7.href at top of el4.href and el5.href IT WORKS but as consequence el4. and el5 won’t work,
any tips?

script

el4 = document.getElementById("edit_href");
el5 = document.getElementById("delete_href");   
el6 = document.getElementById("approve_href");
el7 = document.getElementById("deny_href");


el4.href = "../article/submit-article.php?";        
el5.href = "myaccount.php?mydraft=true&delete=true";

el6.href = "myaccount.php?rec_approved=true&approve=true";
el7.href = "myaccount.php?rec_denied&deny=true";

php

if(isset($_GET['mydraft']))
{echo"
    < href=''  id=edit_href >edit</a>
    <a href='' id=delete_href >delete</a>";
}
if ( (isset($_GET['rec_waiting'])) || (isset($_GET['rec_denied'])) )
    {echo"  
        <a href='' id=approve_href  >approve</a>";

        if(!isset($_GET['rec_denied']))
        {echo"  
        <a href='' id=deny_href >deny </a>";
        }
    }

Javsscript code need not null judgment.because some element is null.look this.

    el4 = document.getElementById("edit_href");
    el5 = document.getElementById("delete_href");   
    el6 = document.getElementById("approve_href");
    el7 = document.getElementById("deny_href");


        if(el4!=null){
        el4.href = "../article/submit-article.php?";        
        el5.href = "myaccount.php?mydraft=true&delete=true";
    }

    if(el6!=null){
    el6.href = "myaccount.php?rec_approved=true&approve=true";
}
    if(el7!=null)
{
    el7.href = "myaccount.php?rec_denied&deny=true";
}

HTML documnet is From top to bottom of the execution.if Appear the wrong in javascript tag middle.So the code after will not be executed
