I'm new with this JQuery Mobile thing. And the first problem i met in this is i can't set "selected" attr on multiple select option to "false" / unselected in JQuery mobile using Javascript.
A documentation i found told me to refreshing a select so i can manipulate it via javascript here in the bottom of it's page: http://jquerymobile.com/demos/1.0a4.1/docs/forms/forms-selects.html
I've done it. But i don't know if i did it wrong or what. Here is my code :
<script type="text/javascript">
function SelectAll(){
var select=document.getElementById('sfruit');
if (select.options[1].selected == true){
alert('All Selected');
for (x in select.options){
if(x > 1){
if (select.options[x].selected == true){
alert(select.options[x].value+' selected');
RefreshSelect();
select.options[x].selected == false;
}else{
alert(select.options[x].value+' unselected');
}
}
}
}
}
function RefreshSelect(){
var myselect = $("select#sfruit");
myselect[0].selectedIndex = 5;
myselect.selectmenu("refresh");
}
</script>
<select onChange="SelectAll()" data-native-menu="false" id="sfruit" name="sfruit" multiple>
<option>Select Fruit</option>
<option value="all" selected>All</option>
<option value="apple">Apple</option>
<option value="orange">Orange</option>
<option value="grape">Grape</option>
<option value="melon">Melon</option>
</select>
What i actually want is when i select "All" option, other option that have been selected become unselected. I'll attaching the image if u all still doesn't understand what i mean, later, it's already late here.
Thanks guys. And please help me. .. :)
I think this is what you want
$(window).load(function(){
$("select#sfruit").change(function () {
$("select#sfruit option:selected").each(function (obj) {
if($(this).index()==1){
alert('All Selected');
$("select#sfruit option:selected").removeAttr("selected");
$("select#sfruit option:eq(1)").attr("selected","");
}
});
});
});
<select data-native-menu="false" id="sfruit" name="sfruit" multiple>
<option>Select Fruit</option>
<option value="all" selected>All</option>
<option value="apple">Apple</option>
<option value="orange">Orange</option>
<option value="grape">Grape</option>
<option value="melon">Melon</option>
</select>
