checkboxes and javascripts in .net

i have a checkbox
[HTML]<input name="AllCompanies" id="Checkbox3" type="checkbox" onclick=chkall1() checked/>All Companies
[/HTML]On this onclick I have called the below javascript

Expand|Select|Wrap|Line Numbers
  1. function chkall1()
  2. {
  3. if(document.getElementById("Checkbox3").checked=true)
  4. {
  5. document.getElementById("Checkbox3").checked=false;
  6. for (var n=0; n < document.forms[3].length; n++)
  7. {
  8. if (document.forms[3].elements[n].type=='checkbox' && document.forms[3].elements[n].id!='Checkbox3')
  9. {
  10. document.forms[3].elements[n].checked=false;
  11. document.forms[3].elements[n].disabled=false;
  12. }
  13. }
  14. }
  15. else
  16. {
  17. document.getElementById("Checkbox4").checked=true;
  18. for (var n=0; n < document.forms[3].length; n++)
  19. {
  20. if (document.forms[3].elements[n].type=='checkbox' && document.forms[3].elements[n].id!='Checkbox4')
  21. {
  22. document.forms[3].elements[n].checked=true;
  23. document.forms[3].elements[n].disabled=true;
  24. }
  25. }
  26. }
  27. return false;
  28. }
When I execute this the output is
The all companies check box is checked in the output.

Now the thing I need is when I click on the checked all companies checkbox it must be unchecked and all the checkboxes below this checkbox must be enabled and checked.for this I have written the javascript. When I click it for second time I need the checkbox to be checked for which I have written the else part in javascript and it doesnot work.it works for only one click

Please use CODE tags when posting code.

On line 3, you're setting instead of checking the checked property, i.e. you need double equals (==) instead of single (=).
