pass the parameter in javascript url

Question

I want to pass the parameter value in url.I have the parameter 'redir'.redir value is changed dynamically as 1,2,3,4,5,... or any number I passed the redir value from php.I passed the value to the newpage() function. I want to pass dynamic redir value as in rec_resume_post.php?req_id=1 or rec_resume_post.php?req_id=2.

<?php
 echo '<tr><td>'.$title.'</td><td>'.$c_name.'</td><td>'.$e_first_name.'</td><td>'.$num.'</td><td><input type="submit" value="submit" onClick="newpage('.$req_id.');" /></td></tr>'; 
?>
 <script>
   function newpage(redir){
    window.alert(redir);
    window.open("rec_resume_post.php?req_id=redir");
      }

Answer 1

Try like this:

window.open("rec_resume_post.php?req_id=" + redir);

So it would be like this:

<?php
 echo '<tr><td>'.$title.'</td><td>'.$c_name.'</td><td>'.$e_first_name.'</td><td>'.$num.'</td><td><input type="submit" value="submit" onClick="newpage('.$req_id.');" /></td></tr>'; 
?>
 <script>
   function newpage(redir){
    window.alert(redir);
    window.open("rec_resume_post.php?req_id"+ redir);
      }

Answer 2

Add the variable to the string.

<?php
 echo '<tr><td>'.$title.'</td><td>'.$c_name.'</td><td>'.$e_first_name.'</td><td>'.$num.'</td><td><input type="submit" value="submit" onClick="newpage('.$req_id.');" /></td></tr>'; 
?>
 <script>
   function newpage(redir){
    window.alert(redir);
    window.open("rec_resume_post.php?req_id"+ redir);
      }

Edited: Suggested the join method for combining strings. But as Rahul pointed out below, using + is the best way to combine strings.

Answer 3

您需要像这样连接字符串：

window.open("rec_resume_post.php?req_id="+redir);

Answer 4

更改window.open行，如下所示：

window.open("rec_resume_post.php?req_id=" + redir);
