I'm trying to find out if the Fine Uploader can limit the total amount of images allowed. So lets say I'd like to limit the images to 5 and a user drag and drops or selects 6 images it will prompt the user saying that can't be done due to only allowing a maximum of 5 images.
I've been looking at the documentation but I might have missed it.
Change the validation.itemLimit option to match the max number of files you want to add, change the validation.acceptFiles and validation.allowedExtensions to match only image files (validation docs)
var uploader = new qq.FineUploader({
/* ... */
validation: {
itemLimit: 5,
acceptFiles: 'image/*',
allowedExtensions: ['.jpe', '.jpg', '.jpeg', '.gif', '.png', '.bmp', '.ico', '.svg', '.svgz', '.tif', '.tiff', '.ai', '.drw', '.pct', '.psp', '.xcf', '.psd', '.raw']
}
});
Note: If you want a custom error message, then change text of the messages.tooManyItemsError option to equal the specific error message you want (error handling docs).
You can also add code to the onError callback to customize how and when your message is shown (events docs) or do some other operation.

I'm very new to writing script for Google Sheets, and I'm attempting to create a spreadsheet that will only display a dropdown in a column ("Provisional Notes") if the value in a column ("Certified or Provisional" is "Provisional." If it is "Certified," the user is be able to enter data freely. I'm also wanting to remove the validation if the value changes from "Provisional". I also need the solution to run on the Google Sheets App, as this spreadsheet will be run on an iPad and/or a smartphone.
I've done quite a bit of searching, and only seem to find dropdowns that depend on other dropdowns, rather than leaving a cell blank if the initial dropdown is a certain value.
What I have come up with so far only runs once (even though I've attempted to have it occur on every edit?) Also, if the value changes from Provisional to Certified, the validation does not get removed.
For my practice, I've applied it to only 2 specific cells, rather than the entire 2 columns.
function onEdit2(e){
var dropdownCell = SpreadsheetApp.getActive().getRange('P2');
var certCell = SpreadsheetApp.getActive().getRange('J2');
var rule = SpreadsheetApp.newDataValidation().requireValueInList(['Test 1', 'Test 2'], true).build();
function insertDropdown(){
if(e.certCell.getValue() === "P"){
dropdownCell.setDataValidation(rule);
}
}
}
I greatly appreciate all suggestions!
To delete a data validation you just need to use the method setDataValidation() and set its value to null to delete the data validation present on that cell.
In the following code example, depending on the value inserted I am adding or deleting the data validation. This code example has self explanatory comments:
function onEdit(e) {
// get sheet
var sheet = SpreadsheetApp.getActive().getSheetByName('Sheet1');
// if modifications happen in A
if(e.range.getColumn()==1){
// check inserted value
if(e.range.getValue()=='Provisional'){
// create rule from a list range and set it to the same row in column B
var rule = SpreadsheetApp.newDataValidation().requireValueInList(['A','B']).setAllowInvalid(false).build();
sheet.getRange(e.range.getRow(),2).setDataValidation(rule);
}
// if it is set to certified
if(e.range.getValue()=='Certified'){
// delete any data validation that may have been in its adjacent cell
sheet.getRange(e.range.getRow(),2).setDataValidation(null);
}
}
}
I've got an Array with 17 web links of images
var products:Array;
trace(products)
// Ouput :
"http://www.myWebsite.com/zootopia.jpg"
"http://www.myWebsite.com/james.jpg"
"http://www.myWebsite.com/tom.jpg"
..etc
If I do products[10].movieimage; the output will be the 9th link (something like : "http://www.myWebsite.com/lalaland.jpg")
I'm looking for downloading every images without a dialog box.
I manage to do so for 1 image with the specific link, like that :
function saveImage (event:Event):void {
var stream:URLStream = new URLStream();
var image1:File = File.documentsDirectory.resolvePath("test.jpg");
var fileStream:FileStream = new FileStream();
stream.load(new URLRequest("http://www.myWebsite.com/lalaland.jpg"));
stream.addEventListener(Event.COMPLETE, writeComplete);
function writeComplete(evt:Event):void {
var fileData:ByteArray = new ByteArray();
stream.readBytes(fileData,0,stream.bytesAvailable);
fileStream.openAsync(image1, FileMode.UPDATE);
fileStream.writeBytes(fileData,0,fileData.length);
fileStream.close();
trace("writeComplete");
trace(image1.url);
}
}
Question : Is there a way to download all the images with the web links of my products array ? (and if images already exist, replace them. I could use if (image1.exists){ if (image2.exists){ ..etc for each image. But maybe there is a simplier solution)
If you could show me how, with a bit of code, I could that.
Also, note that I'd like to load the images then in Uiloader, like that :
function loadImages():void {
uiloader1.source = image1.url;
uiloader2.source = image2.url;
etc...
}
Don't over think it. You have your array of images. You have your tested routine for saving one image. Now put it together:
Some function initializes things and kicks it off.
Either splice out (or pop out) an item on the array – OR use a index var to access an item in the array
Pass that to your download function.
When the download completes either pop another item off the array OR increment your index. But first you would test if array.length== 0 OR `index > array.length. If either is true (depending on which method you use), then you are done.
If you want to get fancy you can show a progress bar and update it each time your download completes.
I want to upload 2 scaled images and I do not want to upload the original image. To do this, I set sendOriginal to false. If I set hideScaled to true, no files show in the uploader. If set set hideScaled to false, both scaled images show up in the list. I realize that the documentation says not to use both options this way. Is there another way to achieve what I want? How do I make fineuploader show only 1 file on the file list no matter how many scaled images it has?
I ran into this exact same problem. I also wanted to rename the larger scale to match the original filename and to pass a custom parameter so the server script could sort the images into the db based on scale size.
I used this method as a hackish substitute for an onScaled event. If anyone is still interested.
// Must be onSubmitted, not onSubmit or the DOM element won't be rendered yet.
onSubmitted : function(id, name) {
// scaling.sizes.name = 'thumb'
if (name.toLowerCase().lastIndexOf(' (thumb).jpg') !== -1) {
// Hide the element displaying the thumbnail.
qq(this.getItemByFileId(id)).hide();
// Good place to include any custom parameters based on scale size.
this.setParams({gpsize : 'thumb'}, id);
}
// scaling.sizes.name = 'large'
else if (name.toLowerCase().lastIndexOf(' (large).jpg') !== -1) {
this.setParams({gpsize : 'large'}, id);
// If needed rename file in this event, not before, since filename
// is the hackish hook needed to connect scale size to file id.
var newName = name.slice(0, name.toLowerCase().lastIndexOf(' (large).jpg')) + '.jpg';
this.setName(id, newName);
}
return true;
}
It's not perfect, but it gets the job done without bushwhacking through the script files.
I'm using jqgrid with a lot of data and, as the filter is taking too long, I'd like to show a dialog before the search and close it after the search.
The thing that's happening to me, is that when I run the filter in debug mode I see the methods that open and close the dialog get called before the search and after the search, but when I run the filter without interruptions I can't see the dialog, my filter waits 10 seconds or more to refresh the table but the dialog isn't shown.
is it a syncronous problem? or why isn't my dialog showing up?
Here's my code:
jQuery("#mytable").jqGrid('filterToolbar',{
searchOnEnter : false,
stringResult : true,
defaultSearch:'cn',
beforeSearch: openDialogLoading,
afterSearch: closeDialogLoading
}
);
function openDialogLoading(){
$( "#DialogLoading" ).dialog({
resizable: false,
autoOpen: false,
height: 110,
width: 50,
title: 'Loading...',
modal: true,
bgiframe: true
});
$( "#DialogLoading" ).dialog('open');
}
function closeDialogLoading(){
if ($( "#DialogLoading" ).dialog('isOpen')) {
$( "#DialogLoading" ).dialog('close');
}
}
Thanks
It's really important to know the details of the grid (options which you use). It's important to use local paging to have good performance with large number of rows. I created some demos for you which you can try and the the time of loading/sorting/filtering:
the demo1 uses 13 columns, 400 rows and the page size 20.
the demo2 uses 13 columns, 400 rows and the page size 400 (no local paging).
the demo3 uses 13 columns, 4000 rows and the page size 20.
the demo4 uses 13 columns, 40000 rows and the page size 20.
the demo5 uses 13 columns, 1000 rows and the page size 1000 (no local paging).
You can see that the performance of the grid depends very havy from the page size. You can play more with differnet values of columns, rows and the page size using the JSFiddle demo http://jsfiddle.net/OlegKi/1rmmyeLh/ where I used
rowNum: 20
UPDATED: The demo http://jsfiddle.net/1rmmyeLh/7/ which you posted later in the comment some important problems. Modifing the code so that it do displays the "Loading" gif with anymation is realtively easy, see http://jsfiddle.net/OlegKi/1rmmyeLh/8/.
I included the call of closeDialogLoading(); inside of loadComplete and modified beforeSearch so that it returns true instead of false, which prevent reloading of grid by jqGrid. Additionally I trigger reloadGrid inside of setTimeout manually:
.jqGrid("filterToolbar", {
beforeSearch: function () {
var $self = $(this);
openDialogLoading();
setTimeout(function () {
$self.jqGrid("setGridParam", { search: true })
.trigger("reloadGrid", [{ page: 1 }]);
}, 0);
startTime = new Date();
measureTime = true;
return true; // SKIP filtering
}
})
Such modification of the code solves the issue with displaying of the "Loading" div. On the other side I stay on my opinion, that the main problem which you have is in ingoring the usage of local paging of data (rowNum option).
I want to stress that it's better, in my opinion, to make the application quickly as to display some "Loading" massage and to hold the application slow. You use in the demo rowNum: 4000 with 4000 rows of data. On the other side I can see on my display about 35 rows of data only. If I just change rowNum from 4000 to 30 I see the peformance improvement in about 20 times!!! Now you should set clear your priorities. One can speak long about the difficulty for very stupid user to undesrtand the meaning of pager buttons, but in my opinion the difference in performance in 20 times makes any discussions unneeded. Practically every user have used already applications with pagers. So I strictly recommend you to use local data paging. You will be able to work in the style with much more large dataset (see the demo with 40000 rows and the page size 20, which responsibility is more as 3 times better in IE11 as the responsibility of the demo with 400 rows and no paging).
Recently i've been working on a rather modest application, which lists contacts. When a detail-link was clicked, a popup would come up with more details and an image of that contact.
The table this was based on contained a column photo_reference, which held a path to a folder under /i/. With this setup, it was easy to get the images working for each contact.
The popup i showed was a bunch of htmlcode i put in the region footer, and hid.
<div id="contact_popup" class="contact_pop">
<div class="contact_pop_imgcontainer">
<img id="id_photo" class="contact_pop" />
</div>
</div>
When the detail was clicked, i retrieved data via an application process, and showed a modal dialog of this container.
Now the scope has changed: users need to be able to upload their own images. So, i went to work and made it so the images get uploaded into wwv_flow_files, and then i move them to a new contact_image table. So far so good. But now i want to display these pictures, and here i'm kind of stuck.
* I could include a column in my IR, and put a blob format mask on it with image. I've got this working, but annoyingly. My image table has as primary key the field 'ID'. My contacts table also has 'ID' as PK.
Since IMAGE:APXT_CONTACTS_IMG:SMALL_PHOTO:ID::::::inline: specifies ID as the PK, it uses ID from my contacts table.
My link between tables is APXT_CONTACTS.CONTACT_IMAGE_ID -> APXT_CONTACTS_IMG.ID.
The way i might make it work is to rename my id field in the image table to contact_image_id. (why couldnt the format mask just take the column it's based on as the value :().
I then could hide the column, and take the image with javascript to show in my popup. However, this preloads all images for the amount of selected rows, which isn't entirely bad, but i'm looking for an alternative first.
get_blob_file_src also seems no use to me because of the limited use of the parameters (file browse item, id field), and even then, could i use this through an ajax callback?
I'd much rather be able to get the image blob via ajax to then display in my popup, but i have no clue as to how to do this. I've made a stored procedure which gets the file to download and call this from an application process (ajax callback), and with firebug i can see the post/response, but i wouldn't know how to get this displayed as an image.
Javascript:
function cimg(){
var get = new htmldb_Get(null, &APP_ID., "APPLICATION_PROCESS=get_img", &APP_PAGE_ID.);
get.addParam('x01', 25);
var greturn = get.get();
alert(greturn);
var pic = new Image();
pic.onload = function(){
document.body.appendChild(pic);
};
pic.src = greturn;
};
Page process:
begin
show_small_photo(apex_application.g_x01);
end;
Stored Procedure:
create or replace procedure "SHOW_SMALL_PHOTO"
(p_contact_image_id IN NUMBER)
is
v_mime apxt_contacts_img.mime_type%type;
v_length NUMBER;
v_filename apxt_contacts_img.filename%type;
v_lob BLOB;
begin
SELECT mime_type, lengthb(small_photo), filename, small_photo
INTO v_mime, v_length, v_filename, v_lob
FROM apxt_contacts_img
WHERE id = p_contact_image_id;
OWA_UTIL.mime_header (NVL (v_mime, 'application/octet'), FALSE);
HTP.p ('Content-length: ' || v_length);
-- needed?
--HTP.p ('Content-Disposition: attachment; filename="'||v_filename||'"');
OWA_UTIL.http_header_close;
wpg_docload.download_file (v_lob);
end;
(I'd rather not have to grant execute to public and call the stored procedure via a link.)
This way i'd only have to load the pictures of links clicked. Though this code doesn't work. I get the alert and see a bunch of those weird chars, so i presume that is the blob talking. But i'm not getting an image anywhere.
Am i missing something? Doing something wrong? I'm totally out of clues.
Instead of my existing code, i might make this work through creating another page, and juggle page items and their values around to try and get the same layout going, and then get that page through ajax?
I'm mainly trying to minimize impact (=work) on the existing app, so i wouldn't have to yet again change pages.
TL;DR: is it possible to retrieve and display an image blob from a table not in the report query, preferably through ajax?
This is Apex 4.02 on an 11g db
Thanks,
Tom
To whom it may concern, here is how i solved/worked around it:
I went with the fetch-another-page route. Maybe i was too technical or too difficult about it in my op, but in hindsight i think i could've boiled it down to:
"retrieve an image blob via ajax and display it".
So if that rings any bells for anyone, let me know.
Some rectifying too:
my images table is a child of the contacts table, as such my FK between those is images.contact_id -> contact.id
I've created a new page in my application, and put a form in based on my images table. I only display 2 items of the type 'display image' (a thumbnail and original size), and 2 hidden items, 'ID' and 'CONTACT_ID'. I've removed all that was not necessary: no buttons, no DML-process, no labels, no templates.
The automated row fetch process takes as 'primary key' my contact id, so i can call the page with contact_id in the url (so that i won't have to do an extra select to retrieve the correct id in the image table).
On the page i need the pictures, i then get the page with the photos on it when required (ie: when the detail icon is clicked and i show my popup).
Following piece of code is called within this function
(only code 'missing' here is where i call another page process to fetch me contact details in a json format)
//page 120 only holds the 2 images for a contact. Due to images being in
//blobs and no easy way to dynamically fetch them, i made a small
//form with the 2 photos on, and id + contact_id
//(contact_id made PK for the ARF-process, since this is what is worked with)
//The page is pulled in, and the photos retrieved
//htmldb_get does not do the job! It only pulls the page from cache, which isnt what i want
// arrays with the arguments and their values for the post
var vArgs = new Array();
var vVals = new Array();
vArgs.push("P120_CONTACT_ID");
vVals.push(cid);
$.post('wwv_flow.show',
{"p_request" : "NULL",
"p_flow_id" : $v('pFlowId'),
"p_flow_step_id" : "120",
"p_instance" : $v('pInstance'),
"p_arg_names" : vArgs,
"p_arg_values" : vVals},
function(data){
var oContainerSmall = $("#id_photo_container").empty(),
oSmallPhoto = $(data).find("#P120_SMALL_PHOTO").attr({"id":"id_photo",
"alt":oContact.lastname + " " + oContact.firstname}),
oLargePhoto = $(data).find("#P120_LARGE_PHOTO").attr("alt",oContact.lastname + " " + oContact.firstname);
$("#large_photo_container").empty().append(oLargePhoto);
$("#large_photo_container").css({"display": "block", "visibility": "hidden"});
//Why remove and remake the container?
//for some reason i couldn't find out, the image width and height get reset to 0 after
// an initial display of the enlarged picture and closing its dialogbox.
//I assume it is an apex+css+javascript issue.
//The only fix i was able to find was to remove the div and remake a new one.
// There have to be some properties set on the div and/or its children through
// the closing of the popup dialog (for the larger picture),
// which then prevents subsequent calls to get the correct values.
$("#large_photo_container").remove();
var oContainerLarge = $("<div></div>").attr("id","large_photo_container").css({"display":"block", "visibility":"hidden"});
oContainerLarge.append(oLargePhoto);
$("body").append(oContainerLarge);
//Hardcoded value here! Adapt when necessary
if($("#id_contact_type").val() == "Conference Room"){
var oLink = $("<a/>").attr("href", "#")
.click(function(event){
explode_headshot(event, this);
});
oContainerSmall.append(oLink.append(oSmallPhoto));
} else {
oContainerSmall.append(oSmallPhoto);
};
$("#contact_popup").dialog({modal: true,
width: 750,
resizable: false,
title: oContact.lastname + " " + oContact.firstname,
close: function(event, ui){
$("#id_photo").attr({"src": "", "alt": ""});
}});
});
I wouldn't call it ideal, but it works, and that's all i need at this time :)
I made a very similar application for showing contact details including photos a few months ago in apex.
I found this web page very useful:
http://blog.hilandco.com/2010/05/how-to-show-blob-type-column-as-image.html
Displaying an image can be as easy as creating an item of type: "display Image". Settings: " Blob column returned by sql statement".
And then an sql statement selecting the correct row:
select blob_content
from my_bitmap_table
where ID = ...
