JS for checkboxA to trigger checkboxB to be checked also

[mb224]

Using ASP.NET HTML server controls .... need help with javascript for when checkboxA is checked to trigger checkboxB to be automatically checked also.

this should do it:

<form>
<input type="checkbox" name="cbA" onclick="this.form.cbB.checked=this.checked;" />
<input type="checkbox" name="cbB" />
</form>

thanks ... I will try it later .. but does this mean that cbB is only checked when cbA is checked, right? (i mean not just clicked)

when cbA is UNchecked say, nothing happens to cbB, right?

if you only want it to CHECK checkbox b and not UNCHECK it, you can do this:

<form>
<input type="checkbox" name="cbA" onclick="if(this.checked)this.form.cbB.checked=this.checked;" />
<input type="checkbox" name="cbB" />
</form>

note, sometimes people tab through field elements and use the spacebar to check checkboxes. in this case you'd need to capture the event in that manner as well. i would suggest writing a function with the code i've already given you to account for that.
