I am writing a piece of code, where i have a jqgrid and a filter with a textbox on the top, i have used the jquery ui autocomplete functionality, everything works fine, but i need to customize the functionality now i.e on autocomplete results when i select a option it should filter the grid with the result selected. Following is the example given below:
// i am doing a search on the textbox with auto complete feature
grid.jqGrid('setColProp', 'Name',
{
searchoptions: {
sopt:['cn'],
dataInit: function(elem) {
$(elem).autocomplete({
source:getUniqueNames('Name'),
delay:0,
minLength:0,
matchContains: true,
autoFill:true,
select:function(event,ui){
grid.setGridParam('postData', ui.item.value);
//grid.jqGrid('clearGridData');
grid.trigger('reloadGrid');
return false;
// need to write the code which will trigger the reload here on selection
}
});
}
}
});
On select function i need the selected option to be loaded in the jqgrid, how can i do it. Please suggest solution.
If you have implemented server side sorting and paging for your jqgrid then this should be easy, you simply need to reload the jqgrid.
To reload the grid see this, use this line of code
$("#grid1").trigger("reloadGrid", [{current:true}]);
this will reload the jqgrid, where you can pass in the paramters using postData: and get the filtered data.

The UI designer wants the select2 live search to complete when the 'matcher' function reduces the option set to 1 value, w/o having to press the enter key etc.
Is there a select2 setting for this?
You need to catch "results:all" event and trigger "result:select" - it will select currently highlighted item.
var select2 = new Select2({});
select2.on("results:all", function (params) {
if (params.data.results.length === 1) {
select2.trigger('results:select');
}
});
Select2 loads all items from my list successful, the issue I found when try to select a specific value when page loads. Example:
:: put select2 in a specific html element, no value is selected even all items are loaded.
$('#my_id').select2();
:: When the page is loaded I'm trying to show a specific item selected, but doesn't work as expected, because even selected, the select2 doesn't show it.
$('#my_id').val('3'); //select the right option, but doesn't render it on page loads.
How to make a selected option to pop up when pages loads?
Thanks in advance.
#UPDATED
:: How I load all select2 items (sorry, its jade, not pure HTML):
label(for='category') Category
span.required *
select(id='category', style='width:230px', name='category')
option(value='') - Select -
each cat in categories
option(value='#{cat.id}') #{cat.description}
P.S.: All items from my list are loaded.
:: How I initialize the select2:
Just put the following line code on my javascript and it does successful:
$('#category').select2();
:: How I'm trying to select a specific value:
First attempt:
$('#category').select2(
{
initSelection: function(element, callback) {
callback($('#field-category').val());
}
}
);
Second attempt:
$('#category').val($('#field-category').val());
P.S.: #field-category has a value its a hidden input field and works OK.
You need to use the initSelection option to set the initial value.
If you are using a pre-defined select element to create the select2, you can use the following method
$('select').select2().select2('val','3')
Demo: Fiddle
add a trigger change after setting val:
$('#my_id').val('3').trigger('change');
A very simple way to tackle this problem is :
//Step1: Here assuming id of your selectbox is my_id, so this will add selected attribute to 1st option
$('#my_id option').eq(0).prop('selected',true);
//Step2: Now reinitialize your select box
//This will work, if you haven't initialized selectbox
$('#my_id').select2();
or
//This will work, if you have initialized selectbox earlier, so destroy it first and initialise it
$('#my_id').select2('destroy').select2();
This may help:
$('#mySelect2').val('1'); // Select the option with a value of '1'
$('#mySelect2').trigger('change'); // Notify any JS components that the value changed

Per here initSelection is deprecated in Select2 4.0 and later.
Using Select2 4.0.0 this worked for me:
$('#my_id').select2({val:3});
HT: #Kokizzu
Here is how to make val in select2 just select the corresponding element.
For some reason, select2 doesn't provide the function to look up selections by id.
init:
$("#thing").select2({data:sources, initSelection: function(item, callback) {
// despite select2 having already read the whole sources list when you
// do .val(n) you have to explicitly tell it how to find that item again.
var to_be_selected = null;
$.each(sources, function(index, thing) {
if (thing.id == item.val()) {
to_be_selected = thing;
return;
}
})
callback(to_be_selected);
}})
normal code
// to load the thing with id==3 from the initial sources list.
$("#thing").select2({'val': 3})
For me I was sending selected in the data set still default option was not getting selected. I had to do something like below to make it work -
$(".select").select2({
data: data_names
});
data_names.forEach(function(name) {
if (name.selected) {
$(".select").select2('val', name.id);
}
});
I had a multiple select2 box with multiple selections.
Step 1 was to put my string of school_ids into an array of integers corresponding to the id of each school, and remove a leading zero. I had to do this in a separate script tag.
<script>
var school_ids = <%= raw JSON.parse(#search.school_ids).map{|x| x.to_i} - [0]%>
</script>
Step two was to create the select box, then set the values, then trigger like so:
<script>
$(document).ready(function() {
$('.select2-multiple').select2({
placeholder: "Hit Enter After Selection",
width: 'resolve'
});
$('.select2-multiple').val(school_ids);
$('.select2-multiple').trigger('change');
</script>
trigger just select2 to set the value
$('#my_id').val('3').trigger("change.select2");
and this will trigger select2 with dropdown
$('#my_id').val('3').trigger("change");
I meet with the same problem, this works for me：
Using Select2 > 4.0.0
$('#select_id').val('3').trigger('change');
var option=$(this);
if(option.val()==data.StudentCourses.CourseId)
{
option.setAttribute('Selected');
}
});
i have initilized select2 because i just want few options selected from them.
If you are using select2 v4.0.0 or above, you can check select2 documentation
// Initialize select2 for all select tags
$('select').select2();
// Initialize select2 for a specific id
$('#my-id').select2();
// Initialize select2 for a class
$('.my-class').select2();
// Update the displayed value after changing the selected option.
$('#my-id').trigger('change');
$('.classname').each(function() {
$(this).siblings().find('.select2selection__rendered').text($(this).text())
})
in my case I were dealing with a class then I used this way to set showing content at select2
<option selected value="your_value">your_text</option>
u need to put this at each select box's first option
I have a set of dynamically generated dropdown boxes on my page. basically I clone them using jQuery. now I want to capture the value selected on each dropdown on change event.
I tried something like this which did not work.
$('._someDropDown').live('change', function(e) {
//debugger;
var v = $(this);
alert($(this + ':selected').val());
alert($(this).val());
});
How do I get it done?
To get the text of the selected option
$("#your_select :selected").text();
To get the value of the selected option
$("#your_select").val();
This is what you need :)
$('._someDropDown').live('change', function(e) {
console.log(e.target.options[e.target.selectedIndex].text);
});
For new jQuery use on
$(document).on('change', '._someDropDown', function(e) {
console.log(this.options[e.target.selectedIndex].text);
});
$("#citiesList").change(function() {
alert($("#citiesList option:selected").text());
alert($("#citiesList option:selected").val());
});
citiesList is id of select tag
Check it Out-->
For getting text
$("#selme").change(function(){
$(this[this.selectedIndex]).text();
});
For getting value
$("#selme").change(function(){
$(this[this.selectedIndex]).val();
});
You can try:
$("._someDropDown").val();
To get the value of a drop-down (select) element, just use val().
$('._someDropDown').live('change', function(e) {
alert($(this).val());
});
If you want to the text of the selected option, using this:
$('._someDropDown').live('change', function(e) {
alert($('[value=' + $(this).val() + ']', this).text());
});
try this...
$("#yourdropdownid option:selected").val();
This is actually more efficient and has better readability in my opinion if you want to access your select with this or another variable
$('#select').find('option:selected')
In fact if I remember correctly phpStorm will attempt to auto correct the other method.
In case you want the index of the current selected value.
$selIndex = $("select#myselectid").prop('selectedIndex'));
The options discussed above won't work because they are not part of the CSS specification (it is jQuery extension). Having spent 2-3 days digging around for information, I found that the only way to select the Text of the selected option from the drop down is:
{ $("select", id:"Some_ID").find("option[selected='selected']")}
Refer to additional notes below:
Because :selected is a jQuery extension and not part of the CSS specification, queries using :selected cannot take advantage of the performance boost provided by the native DOM querySelectorAll() method. To achieve the best performance when using :selected to select elements, first select the elements using a pure CSS selector, then use .filter(":selected"). (copied from: http://api.jquery.com/selected-selector/)
You can also use :checked
$("#myselect option:checked").val(); //to get value
or as said in other answers simply
$("#myselect").val(); //to get value
and
$("#myselect option:checked").text(); //to get text
wasted my day while searching how to get selected options values in JQuery UI widget by Michael Aufreiter. Here's the link to his demo site and github: http://quasipartikel.at/multiselect/
As a result I just need value fields of selected options without POST/GET sendings to PHP script.
I tried many methods and resultless.
Need your help and ideas
*Found many topics about jquery ui multiselect but useless because of Aufreiter :s *
That should work. Tested with Chrome console
$("#countries").val();
I went to the site you've got listed above, and was able to run this in my chrome console:
$('.ui-multiselect .selected li').each(function(idx,el){ console.log(el.title); });
It seems like the values you want are stored in the title attributes of the list items within the div.selected element.
Edit:
Doh! Well of course you want the values. Sorry mate. Completely missed that. The real goods are stored in the jQuery data() objects. In this case, the key you want is 'optionLink'. It maintains a reference to an option element. Each list item in the '.selected' div used the jQuery.data() method to add the underlying option to it.
So, you need to get the selected list items, iterate through, grab the 'optionLink' from the data jQuery data store, and then get the value.
The following code works on the example page:
$('.ui-multiselect .selected li').each(function(idx,el){
console.log(el);
var link = $(el).data('optionLink');
// link now points to a jQuery wrapped <option> tag
// I do a test on link first. not sure why, but one of them was undefined.
// however, I got all four values. So I'm not sure what the first <li>
// is. I'm thinking it's the header...
if(link){
// here's your value. add it to an array, or whatever you need to do.
console.log(link.val());
}
});
This is the first I've seen of the multiselect. It's slick. But I sympathize with your frustration trying to get something out. A 'getSelectedOptions()' method would be nice.
Cheers
Try accessing the selected values on the close event.
e.g.
$("#dropdown").multiselect({
header: false,
selectedList : 1,
height: "auto",
}).multiselectfilter().bind("multiselectclose", function(event, ui) {
var value = $("#dropdown").val();
});
Hope that helps.
Best solution
$('#select').multiselect({
selectAllValue: 'multiselect-all',
enableCaseInsensitiveFiltering: true,
enableFiltering: true,
height: "auto",
close: function() {
debugger;
var values = new Array();
$(this).multiselect("getChecked").each(function(index, item) {
values.push($(item).val());
});
$("input[id*=SelectedValues]").val(values.join(","));
}
});
You can try this:
$('#ListBoxId').multiselect({
isOpen: true,
keepOpen: true,
filter: true
});
After working on with master detail with JQGrid , I am trying to get partial view data added to a div block.
what I am trying to do is
afterEditCell: function () {
$.ajax(
url: "/order/Selected/",
type: "GET",
success: function (response, status, xhr) {
var jqContainer = $('.right');
jqContainer.html(response);
)
},
I am using inline cell editing
jQuery('#list10_d').jqGrid('editRow', id, true,);
ONce I edit value in cell it does send the update to server wher I am able to update selected dataitems with value.
Once this is done I want to load partial view which contains information about selected data item
afterEditCell event never fires.
I have checked the ajax call by adding it to $().ready.
Am I using the right event. Is there a better way to add partial view after row has been edited?
Regards,
Mar
There are a misunderstanding because jqGrid is a grid which can do probably too many things. The problem is that Inline Editing, Form Editing and Cell Editing are three absolutely different implementation of jgGrid editing. You can combine Inline Editing and Form Editing. There are some common grid settings used during all of editing modes. The events used by editRow can be defined as parameters of editRow. You can use succesfunc or aftersavefunc for your purpose. The Events of the cell editing will be
not fired by editRow which is the part of Inline Editing.
I may have got one solution from another post on SO
jqgrid reload grid after successfull inline update / inline creation of record
added
jQuery(document).ready(function () {
function updateSelected(rowid, result) {
alert("Hello");
return true;
}
and inside JQGrid script
jqGrid('editRow', id, true, '', updateSelected, '', '', '');
Though it works for me I will stillwant to know if it is possible to do so using cell events?

Mar
