I have written my first jquery mobile site using their multipage template.
In my application, Changes in the main page can affect the selected value in a drop down in a sub page. The first time I go to the sub page, the correct option is selected and displayed. After that, when I go to the sub page, the correct option is selected (ticked), but the wrong option is displayed.
I created a jsfiddle to demonstrate this... http://jsfiddle.net/afePj/2/
page one lets you select an option...
<select name="selectname1" id="selectid1" onChange="changePageTwo()">
<option value="1">A</option>
<option value="2">B</option>
<option value="3">C</option>
</select>
...and sets the selected value on page two to match...
function changePageTwo() {
select1 = document.getElementById('selectid1');
select2 = document.getElementById('selectid2');
select2.selectedIndex = select1.selectedIndex;
}
...when you arrive on page two I would like the selected value to be displayed. But after the page has been displayed once, the option it shows never changes...
<select name="selectname2" id="selectid2">
<option value="1">A</option>
<option value="2">B</option>
<option value="3">C</option>
</select>
Any ideas about how I can make the sub page display the selected value?
Thanks
When you update a select menu in jQuery Mobile you need to call the select menu widget's refresh menu so that the display is updated to match the native elements
For example
$('selectid2').selectmenu('refresh');

I have a multiselect bootstrap picker and would like to find the specific option that was just selected. For example, if I have the picker set to something like this:
<select class="form-select selectpicker" multiple aria-label="Default example">
<option value="Apple">Apple</option>
<option value="Cherry">Cherry</option>
<option value="Papaya">Papaya</option>
<option value="Kiwi">Kiwi</option>
</select>
When the user selects their first option, "Cherry", I would like to alert("Cherry"). When the user then selects their second option, "Apple", I would like to alert("Apple").
I have tried to use the option:selected:last value, but this only works to display the last option in the array of selected option. I would like to display the option that was most recently selected, regardless of its place in the array of selected options. Any insight is greatly appreciated.
EDIT: This questions was closed due to being marked as similar to the question found here: Get selected value in dropdown list using JavaScript
After looking through all of the provided answers in that link, I am not convinced that the questions are the same. I would like to get the most recently selected text in a multiselect picker, not the only selected option in a single select. So, if a user has both Apple and Papaya options selected, but selected the Apple option after selecting the Papaya option, I would like to alert("Apple"). Thanks.
Here Are Two Methods By which you can Use Alert.
First Method: With OnChange
<select class="form-select selectpicker" multiple aria-label="Default example" onchange = "alert(this.value)">
<option value="Apple">Apple</option>
<option value="Cherry">Cherry</option>
<option value="Papaya">Papaya</option>
<option value="Kiwi">Kiwi</option>
</select>
Second Method: Involves An Event Listener But Its Doing The Same Thing(Javascript)(Assuming That The ID of The Select Tag is selector
function change(){
alert(this.value)
}
document.getElementByID("selector").addEventListener("onchange",change)
<select id="location-search" onChange="window.location.href=this.options[this.selectedIndex].value;"> >
<option value="http://dignitytech.com/efront/contact-us/">Ireland</option>
<option value="http://dignitytech.com/efront/united-kingdom-2/">United Kingdom</option>
<option value="http://dignitytech.com/efront/spain/">Spain</option>
<option value="http://dignitytech.com/efront/romania/">Romania</option>
</select>
Now i want to change the dropdown value as per page change.
Anybody help me
You should be able to achieve this with this simple line of code executed on page load:
$('#location-search').val(location.href);
Based on what you already have, I'm assuming that you have exactly that select on multiple pages. If so, then simply on each page mark appropriate value (so when you're on contact-us, mark that option with selected attribute).
I have a multiselect dropdown menu where each option has a checkbox and more than one option can be selected at once. I'm using a jQuery multiSelect plugin generate the dropdown.
<select id="types" multiple="multiple" size="5">
<option value="">Show All</option>
#{
<option value="Gains">Gains</option>
<option value="Losses">Losses</option>
<option value="Adjustments">Adjustments</option>
<option value="Future">Future</option>
<option value="Deliveries">Deliveries</option>
<option value="Recoveries">Recoveries</option>
<option value="Full Payout">Full Payout</option>
<option value="Early Payout">Early Payout</option>
<option value="Charge Offs">Charge Offs</option>
<option value="Returns">Returns</option>
<option value="Transfers">Transfers</option>
<option value="Ins. Write-offs">Ins. Write-offs</option>
}
</select>
What I need to be able to do is separate the options into 2 sections. The first 4 in a section and the last 8 in a section. If an option is selected in one section, then any options that are selected in the other section are then unselected. This is already setup in a C# .NET application. I am having to replicate the functionality. I don't have access to the .NET code. At first I thought maybe I could put the different options into separate divs and just check whether an option was selected in each div but I get validation errors when I try to do that. I'm not really sure what else I could try. Any help with this would be great. Thanks.
try using classes, attach a jquery check box click(), check for class if ( $(this).hasClass("checkboxSection1") ) then uncheck all the other ones like so $(".checkboxSection2").prop('checked', false);
so some simple code is
$("myForm :checkbox").click( function(){
$(this).hasClass("checkboxSection1")?
$(".checkboxSection2").prop('checked', false):
$(".checkboxSection1").prop('checked', false);
});
How about giving them a set of classes e.g. 'option1' & 'option2', then you can do a little javascript/jquery to handle the logic of the selection process...
I am trying to create a select element which has a basic list, then when the user hovers over an option it expands to shows a more complete list.
I started by using css to hide all the values I wanted hidden, but this did not adjust the height of the select dropdown, so I was left with a lot of white space.
I then tried to have two selects, one with the reduced list, the other with the complete list(which is hidden). I then used javascript to copy the options from the complete list to the reduced list, when a user hover on the 'Other' optgroup. The code for this is shown below.
Html:
<select id="Title">
<option value="">Select...</option>
<option value="MR">Mr</option>
<option value="MISS">Miss</option>
<option value="MRS">Mrs</option>
<optgroup label="Other">Other</optgroup>
</select>
<select id="FullTitle" style="display:none">
<option value="">Select...</option>
<option value="MR">Mr</option>
<option value="MISS">Miss</option>
<option value="MRS">Mrs</option>
<option value="MS">Ms</option>
<option value="DR">Doctor</option>
</select>
Javascript:
<script type="text/javascript">
$('select').find('optgroup').hover(
function () {
var parent = $(this).parent()
var selected = parent.find('option:selected').val()
var id = "#Full" + parent.attr('id')
parent.html($(id).html())
parent.find('option[value="'+ selected +'"]').attr('selected', 'selected')
})
</script>
This works fine in firefox but does not work in either IE or Chrome. I am not sure why.
I was wondering if anyone knows why this is not working or a better approach to my problem?
Hover events don't fire for options in IE and Chrome. There are some scripts you can try that might do this, and I've seen other posts on this site about it as well:
jquery hover event doesn't work with select option tag in google chrome?
From what I've seen, converting this into a div/ul and using css/jquery to make it look like a select list might by your best bet.
i have two drop down boxes
the first drop down contain the mobile brands
and other contains the mobile models
i want them to work like when in first drop down a brand is selected
the second drop down will show models of that particular brand i want to do it with javascript
the drop down values are static values
how i can do that?
<select name="brand">
<option value="samsung">Samsung</option>
<option value="Nokia">Nokia</option>
</select>
<select name="model">
<option value="Galaxy">Galaxy</option>
<option value="N8">N8</option>
</select>
The Drop down will be like the above ones
Use ajax record on the first celect box change and fill it in the second select box. Jquery ajax will function will send data to a function which will fetch data from database .
