I am using Vue.Draggable in my Vue project and trying to drag(clone) a button from sider into a draggable component.
I want to modify the data when I clone the button into the component. But I find that when I modify the data in the list which is binded with the component, the original list that sider used got changed automatically.
Is there some kind of synchronization mechanism in Vue.Draggable or something? I want to change the object data in the component only.
I tried to modify the object in the list2 manually by using a vue extension in Chrome browser. And it still happens. So I think maybe it's not bug in my code.
addEntity (conditionID, entity) {
if (!entity.forChoose) {
}
else {
let variable = 0;
for (let i = 0, len = this.whens.length; i < len; i++) {
if (this.whens[i].entity[0].id == entity.id) {
variable++;
}
}
this.whens[conditionID].entity[0].forChoose = false;
this.whens[conditionID].entity[0].variable = variable;
this.whens[conditionID].entity[0].name = entity.name + '-fake';
}
},
The code above is the event when I drag the data into the component, and changed some variable.
Although I did nothing to the original data in the Sider where I cloned the data from, it still got changed as well.
Is there a way to change the dragged data but do not affect the original data?
Please help me, thank you!
I think this is happening because of the immutability.
so can you try using spread operator to create new shallow copy of your list before you change it.
how to use spread operator (triple dot)
let newArrayOfWhens = [...this.whens]
then use the "newArrayOfWhens" array in your code
You can create a deep clone as well if you want, but try to avoid it if it is not necessary.
you can use a library call "lodash" to do it very easily
deepClone
I had a List that used to work when it was bound directly to a store but now I want that list to get it's data from a queryBy on the original store.
Looking at the documentation is seems like setItems should do what I want.
var myStore = Ext.getStore('myStoreData');
var myData = myStore.queryBy(function(item) {
return item.get('status') !== null;
});
// At this point myData looks valid and has the data I want.
// Ext.apply.create.Class {all: Array[5], items: Array[5], keys: Array[5], indices: Object, map: Object…}
Ext.getCmp('myListComponent').setItems(myData.items);
I keep getting the error "Object [object Object] has no method 'getItemId'". I tried various other incantations but without success. I also took a look at setData and add but without success.
========================
After getting Thiem's answer I just ended up creating a function that would create a filtered copy of an existing store and then just setting the List store to that. Code below for others edification...
storeCopy: function(store, filterBy) {
var records = [];
var allRecords = null;
if(filterBy)
allRecords= store.queryBy(filterBy);
else
allRecords= store.queryBy(function(){return true;});
allRecords.each(function(r){
var rec = r.copy();
rec.setId(r.getId());
records.push(rec);
});
var store2 = new Ext.data.Store({
recordType: store.recordType
});
store2.add(records);
return store2;
},
Thanks all.
setItems method does a totally different thing. For example, says you have an Ext.Container which consists of a form, some fields, and some interaction buttons. These things are call child components, or items of the container. They are oftenly declared in the items config of the parent container and setItems is designed to programmatically set the value of that config. So it has nothing to do with the store logic.
In your situation, here is one of the solutions:
Create a store instance which contains filtered data.
Use this command: yourList.setStore('yourFilteredStore')
And it should reload... hope this helps
I am using extjs 4.1.1a for developing some application.
I had a form consisting of two combo-boxes and an item-selector.
Based on the value selected in first combo-box , the itemselector will load its data from database. This is working fine.
My problem is, if i reselect the first combo-box the new data will be displayed in itemselector along with previous data displayed in itemseletor .That is previous data displayed in itemselector will remain there itself.
for example: name "test1" consists of ids 801,2088,5000. on selecting test1 in firstcombobox itemselector must show output as below.
and if "test2" consists of ids 6090,5040. on selecting test2 in firstcombobox itemselector must show output as below.
problem is. for first time if i select "test1" from firstcombobox , output will come as expected. if i reselect "test2" from firstcombobox , output will come as below.
as you can see, previous data displayed (marked in red rectagle) remains there itself with new data displayed (marked with green rectangle).
I want for every reselection of first combobox, previously displayed data in itemselector to be erased before printing new data on itemselector.
How can I reset the itemselector for every reselection of first combobox?
You should remove all items from the store of the itemselector by the removeAll command. After that you should load the store of the itemselector.
itemselector.store.removeAll();
itemselector.store.load();
Any solutions above solve my problem.
i found solution from Sencha Forum.
https://www.sencha.com/forum/showthread.php?142276-closed-Ext-JS-4.0.2a-itemselector-not-reloading-the-store
in the itemselector.js file, change the line marked below.
populateFromStore: function(store) {
var fromStore = this.fromField.store;
// Flag set when the fromStore has been loaded
this.fromStorePopulated = true;
// THIS LINE BELOW MUST BE CHANGED!!!!!!!!!!!!
fromStore.loadData(store.getRange()); //fromStore.add(store.getRange());
// setValue waits for the from Store to be loaded
fromStore.fireEvent('load', fromStore);
},
You need to insert...
this.reset();
at the head of the function that is inserting the data.
As an example...
Ext.override( Ext.ux.ItemSelector, {
setValue: function(val) {
this.reset();
if (!val) return;
val = val instanceof Array ? val : val.split(this.delimiter);
var rec, i, id;
for (i = 0; i < val.length; i++) {
var vf = this.fromMultiselect.valueField;
id = val[i];
idx = this.toMultiselect.view.store.findBy(function(record){
return record.data[vf] == id;
});
if (idx != -1) continue;
idx = this.fromMultiselect.view.store.findBy(function(record){
return record.data[vf] == id;
});
rec = this.fromMultiselect.view.store.getAt(idx);
if (rec) {
this.toMultiselect.view.store.add(rec);
this.fromMultiselect.view.store.remove(rec);
}
}
}
});
are u got it?
when u select that combobox frist stoe of item selector is null after store load with ur pass the para meters
for example
store.load(null),
store.proxey.url='jso.php?id='+combobox.getrawvalue(),
store.load();
like that so when ur select a value in ur combobox that time ur used a listeners to ur combobox in that listners ur used above code , select ur some value in combobox that time frist store is get null after ur pass some values to json.php then store load with responce so that time old data is remove and new data load in that store
if u post ur code i will give correct code
I ran into the same issue with ExtJS 4.2.1. I got it to work by calling reload() on the data store and then setValue() with an empty string on the item selector in the data store's reload() callback.
Ext.create("Ext.form.field.ComboBox", {
// Other properties removed for brevity
listeners: {
change: function(field, newValue, oldValue, eOpts) {
Ext.getStore("ExampleStore").reload({
callback: function() {
Ext.getCmp("ExampleItemSelector").setValue("");
}
});
}
}
});
Ext.create("Ext.data.Store", {
storeId: "ExampleStore",
// Other properties removed for brevity
});
Ext.create("Ext.form.FormPanel", {
// Other properties removed for brevity
items:[{
xtype: "itemselector",
id: "ExampleItemSelector",
// Other properties removed for brevity
}]
});
For any folks that are curious, I'm fairly convinced there's a bug in the item selector's populateFromStore() function. When the function is called, it blindly adds all of the values from the bound store (store) to the internal store (fromStore). I suspect there should be a call to fromStore.removeAll() prior to the call to fromStore.add(). Here's the relevant code from ItemSelector.js.
populateFromStore: function(store) {
var fromStore = this.fromField.store;
// Flag set when the fromStore has been loaded
this.fromStorePopulated = true;
fromStore.add(store.getRange());
// setValue waits for the from Store to be loaded
fromStore.fireEvent('load', fromStore);
},
EDIT 12/18/2013
If you've configured any callback events on the item selector (e.g. change), you may want to disable the events temporarily when you call setValue(""). For example:
var selector = Ext.getCmp("ExampleItemSelector");
selector.suspendEvents();
selector.setValue("");
selector.resumeEvents();
I had the same problem and finally I decided to modify the extjs source code, not considering it a big issue as extjs itself its saying in the start of the file
Note that this control will most likely remain as an example, and not as a core Ext form
control. However, the API will be changing in a future release and so should not yet be
treated as a final, stable API at this time.
Based on that, as jstricker guessed (and sadly I didn't read and took me a while to arrive to the same conclusion), adding fromStore.removeAll() before fromStore.add() solves the problem.
Outside of the problem (but I think it can be interesting as well), additionally, I also added listConfig: me.listConfig in the MultiSelect configuration (inside createList), that way it's possible to format each item additional options (such as images, etc.) setting in the 'itemselector' the option listConfig as it's explained in the (irrealistic) documentation.
Need to reset the store used in ItemSelector that can be done by setting Empty object like below. Also need to call clearValue() method of ItemSelector component.
store.setData({});
ItemSelectorComponent.clearValue();
I am rather new to sencha touch, I've done a lot of research and tutorials to learn the basics but now that I am experimenting I have run into a problem that I can't figure out.
I have a basic DataList which gets its data from a store which displays in a xtemplate.
Within this template I have created a member function which requires store field data to be parsed as a parameter.
I would like to make a thumbnail image (that's source is pulled from the store) execute the member function on click/tap.
I can't find any information on this within the docs, does anyone know the best way to go about this?
Here is a code example (pulled from docs as I can't access my actual code right now).
var tpl = new Ext.XTemplate(
'<p>Name: {name}</p>'
{
tapFunction: function(name){
alert(name);
}
}
);
tpl.overwrite(panel.body, data);
I want to make the paragraph clickable which will then execute the tapFunction() member function and pass the {name} variable.
Doing something like onclick="{[this.tapFunction(values.name)]} " does not seem to work.
I think functions in template are executed as soon as the view is rendered so I don't think this is the proper solution.
What I would do in your case is :
Add a unique class to your < p > tag
tpl : '<p class="my-p-tag">{name}</p>'
Detect the itemtap event on the list
In your dataview controller, you add an tap event listener on your list.
refs: {
myList: 'WHATEVER_REFERENCE_MATCHES_YOUR_LIST'
},
control: {
myList: {
itemtap: 'listItemTap'
}
}
Check if the target of the tap is the < p > tag
To do so, implement your listItemTap function like so :
listItemTap: function(list,index,target,record,e){
var node = e.target;
if (node.className && node.className.indexOf('my-p-tag') > -1) {
console.log(record.get('name'));
}
}
Hope this helps
Hi I'm using JQuery tabs http://jqueryui.com/demos/tabs/ with search results being returned from my server with each row potentially having its own tabs depending on the search results. If the user clicks on the sorting options then the search results change including the tabs within each row returned which may or may not have tabs. In the example above you can see there are 2 records returned and the top record has tabs called Other Videos.
I have been successfully able to retrieve the resultset back from the server and the template is bulding correctly, however i cannot get the .tabs() function to fire? Does anyone have any experience with using tabs and know how I can get my tabs() function to fire?
Here is the code I use to dynamically load the template after the json result set is returned:
$(".searchBox").fadeOut("fast", function () {
$(this).html("").fadeIn("fast", function () {
$("#searchTemplate").tmpl(json.Data.SearchResults.Results).appendTo(".searchBox").fadeIn("fast");
});
});
And here is a for loop that I use to iterate over the results after the template has been loaded with the new html tabs created to try and get the .tabs() function to fire:
for(var i=0;i<json.Data.SearchResults.Results.length;i++){
if (json.Data.SearchResults.Results[i].OtherVideos.length || json.Data.SearchResults.Results[i].VideoFriends.FriendCount > 0)
{
$(document).find("div[id='tabs"+json.Data.SearchResults.Results[i].Counter+"']").tabs();
if ($(document).find("div[id='tabs"+json.Data.SearchResults.Results[i].Counter+"']").length > 0)
alert("it exists");
else
alert("it dont");
}
}
Suffice to say the alert box "it exists" appears successfully so it is finding the dynamically created html tab that the template generated however the tab itself is not being initialized by the statement:
$(document).find("div[id='tabs"+json.Data.SearchResults.Results[i].Counter+"']").tabs();
Does anybody know the reason why or what I'm missing here to get my .tabs() function to fire ...
I've examined the dynamic content and double checked the html code using firebug inspector and everything is according to how it should be the id's are correct, the #id's are there and so on, so my only conclusion is that the .tabs() function is not firing. Is this a limitation on the JQuery tabs itself? Can it not perform this type of "live" loading capability? Is there a callback function I should be using as part of loading the template itself?
Here is a picture of what is being returned after the call to the server without the tabs working:
Okay I fixed the problem, and thought I'd better give my answer for those of you who suffer a similar problem.
I should have placed my for loop inside of the same callback function as the tmpl call e.g:
$(".searchBox").fadeOut("fast", function () {
$(this).html("").fadeIn("fast", function () {
$("#searchTemplate").tmpl(json.Data.SearchResults.Results).appendTo(".searchBox").fadeIn("fast");
// For loop should go here!
});
});
I had the for loop after this block of code and the tabs() function essentially was not referencing the newly created tabs at all.
