At this site there is a 'Cholera facilities"checkbox for triggering the display of a map layer.
The problem is how the checkbox behaves. It is reverse what I expect-- it triggers upon being unchecked , rather than checked ?
<div><input type="checkbox" id="cholera_control" name="cholera_control" />
<label for="cholera_control">Cholera Facilities</label></div>
Just reverse the if
with the else
.
Instead of:
if (showCholera) {
kmlLayerCTF.setMap(null);
} else {
kmlLayerCTF.setMap(map);
}
do:
if (showCholera) {
kmlLayerCTF.setMap(map);
} else {
kmlLayerCTF.setMap(null);
}
This is happening because your initial value is false
.
var showCholera = false;
...then you're reversing it before the if()
statement:
showCholera = !showCholera;
...so when the if()
runs, showCholera
is true
, and the if
is executed instead of the else
.
Change
<input type="checkbox" id="cholera_control" name="cholera_control" />
<input type="checkbox" name="mc-cb" id="mc-cb">
to:
<input type="checkbox" check="checked" id="cholera_control" name="cholera_control" />
<input checked="checked" type="checkbox" name="mc-cb" id="mc-cb">
