I would like to know how to update a row/col and or layout from an external js file on webix. Let's say I have a menu at the left of the screen (col[]) and want to update the right column based on a menu selection. If the menu is composed by
Customers
Orders
Products
And want to update the right column based on the selection calling customers.js, orders.js and products.js
Just like http://webix.com/demos/admin-app/#!/app/orders
That example is very advanced for me, I would like to learn some basic method.
Thanks

You can use webix.ui command or addView API to add a new UI to some specific place on the page.
webix.ajax("config.json", function(text){
$$("layout").addView( JSON.parse(text) );
})
or
webix.ajax("config.json", function(text){
webix.ui( JSON.parse(text), $$("cell_to_replace"));
})
Aquatic,
I also found out an example with .showBatch() API but the console shows "Uncaught TypeError: $$(...).addView is not a function" on both functions, are those part of PRO version? what is wrong?
My code is:
$$("workArea").addView("clientes");
or
$$("workArea").showBatch("batClientes");
on:{
onMenuItemClick:function(id) {
$$("workArea").addView(id);
}
}
I am new to Phonegap programming.I created one HTML page(ListScreen.html) with NavigationBar plugin.In ListScreen I displayed list of data.When I select the one list item it goes to another HTML page that is DetailsScreen.html page.I tried the code in ListScreen.html as follows:
$(document).on("click", "#lstMyList li" ,function (event) {
window.location.href='DetailsScreen.html';
});
How to send the selected item from ListScreen.html to DetailsScreen.html.Please help me.
You can use local storage. I supports any JavaScript object.
localStorage.setItem("oneKey", anObject);
var anObject = localStorage.getItem("oneKey");
It works perfectly for me. try this way -
var foo = localStorage["bar"];
localStorage["bar"] = foo;
From the Worklight tutorial - 05_05_Enabling_translation.pdf (Sample app), we can
1. Define the translated message in messages.js
2. Reference the message in HTML as the ID of an HTML element with class="translate" or as a JavaScript object property Messages.<ID>.
3. Implement a languageChanged function to set a new value of Messages.<ID> and update the content to selected language.
In the example - languageChanged(lang) function:
$("#sampleText").html(Messages.sampleText);
$("#headerText").html(Messages.headerText);
$("#actionsLabel").html(Messages.actionsLabel);
is used to update the content to selected language.
From my understanding, it is required to write the above line of codes to update the content to selected language.
Is there a better way to update the content if there are lots of elements?
You can easily iterate over all elements by using jQuery selectors and update text, e.g. something like
$(".translate").each(function(index, element){
element = $(element);
var elementId = element.attr("id");
element.text(Messages[elementId]);
});
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 webpage with multiple jqgrids each with inline editing enabled, "action" column (edit icons) enabled and pager disabled. I need to handle the delete event for each row so that I can process the delete without reloading server-side data. I've looked at the approach mentioned in jqGrid Delete a Row and it's very helpful except I have two questions that are stumping me -
Are there more details around the rp_ge parameter in the delOptions.onClickSubmit event?
My column has the delOptions set as this -
delOptions: {onclickSubmit: function(rp_ge, rowid) {return onRowDelete(rp_ge,rowid);}},processing:true }},
Is there a way to get the grid id from within that event? I'd like to have a generic function that I can use to handle delete events from all the grids on the page. The rp_ge parameter has a gbox which sometimes contains the grid id appended? But I have no idea what it is since i'm not able to figure out when it's populated, when it's not.
function onRowDelete(rp_ge, rowid) {
//hardcoded grid id.. don't like it.
var gridid = '#Grid_X';
//what is this gbox?? can i get grid id predictable from it?
//var gridid = rp_ge.gbox.replace("#gbox_", "");
var grid = $('#Grid_X');
rp_ge.processing = true;
var result = grid.delRowData(rowid);
if (result) {
$("#delmod" + grid[0].id).hide();
}
return true;
}
In the jqGrid Delete a Row approach, the code $("#delmod"+grid[0].id).hide(); is hiding the popup delete confirmation dialog manually. What I noticed is that when the dialog pops-up, jqgrid de-emphasizes the background page (makes it light greyish). But after the popup is manually closed (hidden actually?), the background remains de-emphasized. So it looks like the page doesn't have focus (or even disabled). Any way this can be fixed? This can also be seen on the demo that Oleg wrote.
Any help would be appreciated.
(PS - I would've commented on the same post but I don't have enough points to comment on someone else's answer yet.)
In answer to your second point.
Several examples by Oleg such as this one have the following modification.
$("#delmod" + grid[0].id).hide();
is replaced with
$.jgrid.hideModal(
"#delmod"+grid_id,
{gb:"#gbox_"+grid_id,jqm:rp_ge.jqModal,onClose:rp_ge.onClose}
);
This will return focus after the delete operation.
