hello my name is claudia am new to this community my English is not very good my diculpas in advance, I'm doing a small project for a thesis and I am a beginner in yii and need your help, I have seen many tutorials dependent DropDownList, but I need to complete several dependent texfields 1 dropdown and I can not make it work.
I have two tables: program and partediario
program
id
game
article
drawing
variant
partediario
id
id_programa (heading-dropdownlist)
article
drawing
variant
meters
I need that when you create (_form) an item appears on a dropdownlist for which you select an item and textfields of article, drawing, variant, autocompleten automatically with program table data and then the data is saved.
I can attach appreciate some basic example.
thanks sooooo
In MyajaxController:
public function actionGetDropDownInfo(){
$selected_drop_down_val = $_POST['ddl']; // the drop down list's changed value
$article = "..."; // what you have to process with corresponding to $selected_drop_down_val
$drawing = "..."; // what you have to process with corresponding to $selected_drop_down_val
$variant = "..."; // what you have to process with corresponding to $selected_drop_down_val
echo json_encode(array(
'article' => $article,
'drawing' => $drawing,
'variant' => $variant
));
Yii::app()->end();
}
In your form, add a little of jQuery:
<script>
$(function(){
$('#drop_down_list_id').on('change', function (e) {
//var optionSelected = $("option:selected", this);
var selectedValue = this.value;
$.ajax({
type: "POST",
url: "<?php echo Yii::app()->createUrl('Myajax/GetDropDownInfo')?>",
data: {ddl: selectedValue}, //post a selected value of drop down list
dataType: 'json',
beforeSend: function () {$('.loading-icon').show();},
complete: function () {$('.loading-icon').hide();},
success: function (data) {
// bind returned data into your fields
$('#article-field-id').val(data['article']);
$('#drawing-field-id').val(data['drawing']);
$('#variant-field-id').val(data['variant']);
}
});
});
</script>
Above is one of ideas how to achieve your point. I think your question was not much related to Yii, if you search by tag form, jQuery or ajax, you can find the other solutions that has been proposed.

I have a problem in preserving the values in the textbox after dropdownlist selected index changed in asp.net mvc. Below is the code for initiating the dropdown onchange event.
#Html.DropDownList("BranchId",null,"Select Branch", new { onchange = "location.href='/User/GetRoles?BranchId='+this.options[this.selectedIndex].value" })
Аnd the roles dropdown binded with the values, but what i typed in the textboxes just above the branch dropdown get lost.
Please help me.

This is because you are changing your URL location by using location.href. What exactly do you want to achieve? If you need to load certain logic, you might as well bind change event to jQuery function that could load data from the server, and then you do something with that data.
$(document).ready(function() {
$("#BranchId").change(function() {
$.getJSON(YourUrlThatReturnsValues, {data: yourparameter}, function() {
// do some processing here.
});
});
});
The other option is to use Ajax Helpers instead of Html Helpers. Instead of Html.DropDownList you would use Ajax.DropDownList.
You may try something like that:
$(function () {
$('#BranchId').change(function () {
var id = $("#BranchId option:selected").val();
var data = {BranchId: id };
$.get("#Url.Action("User", "GetRoles")", data).done(function(d){
$('.somediv').val(d.rolename)
});
});
I'm using jquery DataTables (from datatables.net) with server-side processing and ColumnFiltering add-on. I need to add a callback which will compute subtotals based on filtered data. In order to achieve this I want to make a separate ajax call. How can I extract the current ajax parameters?
Assign datatable object to a var on creation, for example:
var oTable = $("selector").dataTable({...});`
Later use this:
var params = oTable.oApi._fnAjaxParameters(oTable.dataTable().fnSettings());
it returns all ajax parameters which would be sent in a normal data loading request for datatables. Make your ajax call like this :
$.post("url",$.param(params),function(response){....});
If you're using DataTables 1.10 (the current version as of this answer), this is now a lot easier to access with the ajax.params() method.
Example from http://datatables.net/reference/api/ajax.params()
var table = $('#example').DataTable( {
ajax: "data.json",
serverSide: true
} );
table.on( 'xhr', function () {
var data = table.ajax.params();
alert( 'Search term was: '+data.search.value );
} );
Based on your question it looks like you might want the ajax ordering parameters as well. The code below assumes you have a datatable called 'your_table'.
$.ajax({
url: "your_url",
data: {
orderColumn: your_table.ajax.params().order[0]['column'],
orderDirection: your_table.ajax.params().order[0]['dir'],
searchText: your_table.ajax.params().search.value
}
});
Thank you MrDerp for your response - helped me with my own table! I had difficulty finding the other parameters so I thought I would share here.
Try this:
table.on( 'xhr', function () {
var data = table.ajax.params();
var filter_values = [];
//suppose you have 10 columns in your datatable
for(i=0;i<10;i++){
search_value = "sSearch_"+i;
filter_values.push(data[search_value])
}
console.log(filter_values);
});
For an implementation of Magnific Popup, I need to pass a post id to the ajax settings. The post id is stored in a data attribute of the element to which Magnific Popup is bound. I would like this to work:
html element:
<a data-id="412">Clicke me</a>
Javascript:
$('.element a').magnificPopup({
type: 'ajax',
ajax: {
settings: {
url: php_array.admin_ajax,
type: 'POST',
data: ({
action:'theme_post_example',
id: postId
})
}
}
});
Where postId is read from the data attribute.
Thanks in advance.
$('.element a').magnificPopup({
callbacks: {
elementParse: function(item){
postData = {
action :'theme_post_example',
id : $(item.el[0]).attr('data-id')
}
var mp = $.magnificPopup.instance;
mp.st.ajax.settings.data = postData;
}
},
type: 'ajax',
ajax: {
settings: {
url: php_array.admin_ajax,
type: 'POST'
}
}
});
Here is how to do it:
html:
<a class="modal" data-id="412" data-action="theme_post_example">Click me</a>
jquery:
$('a.modal').magnificPopup({
type: 'ajax',
ajax: {
settings: {
url : php_array.admin_ajax,
dataType : 'json'
}
},
callbacks: {
elementParse: function() {
this.st.ajax.settings.data = {
action : this.st.el.attr('data-action'),
id : this.st.el.attr('data-id')
}
}
},
parseAjax: function( response )
{
response.data = response.data.html;
}
});
php
function theme_post_example()
{
$id = isset( $_GET['id'] ) ? $_GET['id'] : false;
$html = '<div class="white-popup mfp-with-anim">';
/**
* generate your $html code here ...
*/
$html .= '</div>';
echo json_encode( array( "html" => $html ) );
die();
}
As this answer was the original question regarding inserting data into Magnific's ajax call, I'll post this here.
After many hours of trying to figure this out, you should know that if you're using a gallery with the ability to move between gallery items without closing the popup, using elementParse to set your AJAX data will fail when you visit an item after already viewing it (while the popup is still open).
This is because elementParse is wrapped up in a check that it makes detect if an item has already been 'parsed'. Here's a small explanation as to what happens:
Open gallery at item index 2.
Item has not been parsed yet, so it sets the parsed flag to true and runs the elementParse callback (in that order). Your callback sets the ajax options to fetch this item's data, all is well.
Move (right) to item index 3.
Same as above. The item has not been parsed, so it runs the callback. Your callback sets the data. It works.
Move (left) back to item index 2.
This time the item has been parsed. It skips re-parsing the item's element for assumed potential performance reasons.Your callback is not executed. Magnific's ajax data settings will remain the same as if it were item index 3.
The AJAX call is executed with the old settings, it returns with item index 3's data instead, which is rendered to the user. Magnific will believe it is on index 2, but it is rendering index 3's data.
To resolve this, you need to hook onto a callback which is always executed pre-ajax call, like beforeChange.
The main difference is that the current item isn't passed through into the callback. Fortunately, at this point, magnific has updated their pointers to the correct index. You need to fetch the current item's element by using:
var data = {}; // Your key-value data object for jQuery's $.ajax call.
// For non-closures, you can reference mfp's instance using
// $.magnificPopup.instance instead of 'this'.
// e.g.
// var mfp = $.magnificPopup.instance;
// var itemElement = mfp.items[mfp.index].el;
var itemElement = this.items[this.index].el;
// Set the ajax data settings directly.
if(typeof this.st.ajax.settings !== 'object') {
this.st.ajax.settings = {};
}
this.st.ajax.settings.data = data;
This answer can also be used as a suitable alternative to the currently highest voted, as it will work either way.
You may use open public method to open popup dynamically http://dimsemenov.com/plugins/magnific-popup/documentation.html#public_methods
postId = $(this).attr('data-id')
$(this) retrieve the current element (the link you clicked on), and attr the value of the specified attribute.
Is there a simpler list type than DataGrid that can be connected to a store for Dojo?
I would like the data abstraction of the store, but I don't need the header and cell stucture. I would like to be more flexible in the representation of the datalines, where maybe each line calls an function to get laid out...
You ask a really good question. I actually have a blog post that is still in draft form called "The DataGrid should not be your first option".
I have done a couple thing using the store to display data from a store in a repeated form.
I have manually built an html table using dom-construct and for each.
var table = dojo.create('table', {}, parentNode);
var tbody = dojo.create('tbody', {}, table); // a version of IE needs this or it won't render the table
store.fetch({ // this is a dojo.data.ItemFileReadStore, but you cana dapt to the dojo.Store API
query: {},
onComplete: function(itms) {
dojo.forEach(itms, function(itm, idx) {
var tr = dojo.create('tr', {}, tbody);
// use idx to set odd/even css class
// create tds and the data that goes in them
});
}
});
I have also created a repeater, where I have an html template in a string form and use that to instantiate html for each row.
var htmlTemplate = '<div>${name}</div>'; // assumes name is in the data item
store.fetch({ // this is a dojo.data.ItemFileReadStore, but you cana dapt to the dojo.Store API
query: {},
onComplete: function(itms) {
dojo.forEach(itms, function(itm, idx) {
var expandedHtml = dojo.replace(htmlTemplate, itm);
// use dojo.place to put the html where you want it
});
}
});
You could also have a widget that you instantiate for each item.
I've been playing around with IBM's tutorial at this link.

I've done very well so far, but I can't seem to get the drop down list to populate the new group entry. Even the original code isn't working.
//Refresh the data store for the groups dropdown (in case groups added, edited or deleted)
function refreshGroupDropDown() {
var theStore = dijit.byId("edit_contact_group").store;
theStore.close();
theStore.url = "data/groups.php";
theStore.fetch();
}
Thanks!
Update: Still having trouble. I tried this below and still nothing. The function refreshGroupDropDown() is called when the user opens the edit contact windows or new contact window.
//Refresh the data store for the groups dropdown (in case groups added, edited or deleted)
function refreshGroupDropDown() {
var new_store = new ItemFileReadStore({url: 'data/groups.php' , clearOnClose: true});
var theStore = dijit.byId("edit_contact_group");
theStore.store = new_store;
theStore.close();
theStore.fetch();
}
//Clears the "Edit Contact" form, sets it up for adding a new contact
function newContact() {
var contact = contactsGrid.selection.getSelected()[0];
refreshGroupDropDown();
dojo.byId("edit_contact_real_id").value = "";
dojo.byId("edit_contact_id").value = "[NEW]";
dijit.byId("edit_contact_group").reset();
dijit.byId("edit_contact_first_name").reset();
dijit.byId("edit_contact_last_name").reset();
dijit.byId("edit_contact_email_address").reset();
dijit.byId("edit_contact_home_phone").reset();
dijit.byId("edit_contact_work_phone").reset();
dijit.byId("editContactDialog").set("title", "New Contact");
dijit.byId("editContactDialog").show();
}
//Process the adding of a new group to the database
function doNewGroup(e) {
e.preventDefault();
e.stopPropagation();
dojo.byId("new_group_ajax").value = "1";
if(this.isValid()) {
dojo.xhrPost({
form: this.domNode,
handleAs: "json",
load: function(data) {
if(data.success) {
okDialog.set("title","Group created successfully");
okDialogMsg.innerHTML = "The group <strong>"+data.name+"</strong> was created successfully.";
groupsStore.newItem({"id":data.id.toString(),"name":data.name}, {"parent": groupsModel.root, "attribute":"groups"});
groupsStore.save();
newGroupDialog.hide();
okDialog.show();
}
else {
okDialog.set("title","Error creating group");
okDialogMsg.innerHTML = data.error;
okDialog.show();
}
},
error: function(error) {
okDialog.set("title","Error creating group");
okDialogMsg.innerHTML = error;
okDialog.show();
}
});
}
}
Hopefully this helps! I'm a beginner so any help is appreciated.
I figured it out! The issue was with the index.html. The input tag for the groups drop-down list looks like this
<input dojoType="dijit.form.FilteringSelect" name="move_contact_new" store="groupsStore" searchAttr="name" query="{type:'node'}" id="move_contact_new" required="true" style="margin-bottom: 6px" />
The query attribute was never set correctly. Once I deleted query="{type:'node'}" the groups re-populate after adding, editing, or deleting groups.
A beginner answer for a beginner question.
Hope this can help any beginners out there.
Based on what you've posted, the only problem I see is with the line var theStore = dijit.byId("edit_contact_group").store;because it doesn't acutally create a dataStore. You need to make sure you also include something like `var edit_contact_group = new dojo.data.ItemFileReadStore();or an equivalent. Othewise, have you connected the refreshGroupDropDown() function to the appropriated event ('onclick' or whatever) using dojo.connect()? Have you loaded the function refreshGroupDropDown() using dojo.ready? ie. dojo.ready(function(){refreshGroupDropDown();});Those are always the first things that come to mind...
