Check If Selected File Exist?
Jun 3, 2009When i select a file (through html file control) from local machine, before uploading i want to check if the selected file exist(because,after selecting and before submitting the form,user may change the name/delete the file from the source). so after selecting the file, i need to check the same file exist as it is using javascript/ajax. Back end is JSP.Eg: Am selecting abc.jpg from my system and changing the file name form the source as abcd.jpg, now abc.jpg does not exist. But i want to check if exist. If selected file does not exist, i want to display a message before uploading/submitting the form.

View 7 Replies View RelatedJQuery :: Add Select Options Only If Option Doesn't Already Exist
Jul 22, 2010I have two multiple selects on my page. One gets updated via ajax whenever the user filters data (we'll call that select "#select-1"), when they select options from that it then gets moved into the other select (we'll call that "#select-2"). That is all working fine but I'd like to refine it so that they can't select the same data twice.
So, basically, what I'd like to do is add logic within the ajax call to only update the select options in (#select-1) if it does NOT exist in the other select (#select-2).
I have no clue where to even begin with this....do I need to store the val's in an array and then search for each one in the other?

JQuery :: Binding Events To Dynamically Created Elements That Do Don't Exist At All On Page Load
Jul 26, 2010In the examples for live() and delegate(), the selectors match at least one element that already exists. Will either of these commands work on elements for which there is no match at all on page load?
In my case, I want to bind a keyup event to the textareas that jeditable creates. I could probably create custom plug-in (to the plug-in :) to do the job, but I'd like to use live or delegate if they would work.

Determine If Object Exist
Jul 23, 2005I have a script that will set the focus to a particular input box. I want the script to check to see if the input box exist also.
I'm receiving the following error:
'document.ScheduleForm.txtGrossPayroll99' is null or not an object.
The txtGrossPayroll99 is a field that does not exist. I've hard-coded
this name into the script to see if it is working correctly.
I'm using the OnLoad event inside the <Body> tag to execute this
function.
var formInUse = false;
function setFocus()
{
if ((!formInUse) && (typeof(document.ScheduleForm.txtGrossPayroll99) !=
"undefined") && (typeof(document.ScheduleForm.txtGrossPayroll99) !=
null) );{
document.ScheduleForm.txtGrossPayroll99.focus();
}}
Checking If Span Object(s) Exist
Jul 20, 2005We have a JSP website intended for viewing with IE 5 (and above)
On a certain jsp page, there are few span objects
(<SPAN ID="name">text</SPAN>), which are created dynamically.
The spans share the same ID, so we are able to reference them as an
array, in the javascript code :
for example:
<SPAN ID="wow">lala</SPAN>
<SPAN ID="wow")kaka</SPAN>
in the JS code:
wow[0].innerHTML = "fafa";
wow[1].innerHTML = "zaza";
It may occur, since these spans are created dynamically by the JSP
page, that on a certain instance of the page, no spans are created.
My question is - how do we know, in the JS code, that no spans of ID
'wow' exist?
We tried several ways:
if (!wow) alert('no wow'); // If there were no spans, this gives a
js error
tried a few other methods which i cant recall of now..
I know of a workaround - to add a 'dummy' span with the 'wow' ID , but
I prefer to know if there is a better way to deal with this.

Oct 4, 2011Here is the HTML: [URL] I'm trying to uncheck the selected radio button, then set the value to 1 (Yes), basically overwriting theinitialvalue to 1. I've looked at prop(), val(), and attr(), and just don't know where to start. Should I select $('#set_q157 input') or$('#set_q157 input:radio'), or each individual radio?
Do I need to each them, and check if its checked, then change its value, or is there a way to select all three inputs as just one radial button? It would also need to work if the input has not yet been checked.
Menu Item Select On Page Load - Actual Element (a Table) To Set The Background Doesn't Exist
May 9, 2011I have a menu that I have constructed through HTML/CSS/JavaScript. Javascript handles the mouseover and mouseout events to set the background of the menu item/table element with an image. It works great. What my issue is right now is that when the user loads the Home page, I want that to have the background of the item already set. I had a function to do this with a switch clause in a separate javascript file. This function was called immediately (left it outside of any functions so it would execute first). But I'm getting an error because the actual element (a table) to set the background doesn't exist yet.

Code To Check Quantity For Button, But It Will Not Check For Enter Key?
Nov 9, 2011I am a php programmer and not a Javascript programmer and I am trying to help a friend out with his shopping cart. The original programmer (who wrote this years ago and is no longer around) has a button that looks up the quantities in the database for the submitted items, and then displays a prompt if you selected a quantity that is less than the minimum purchase amount.The issue is if the user enters a smaller amount than allowed and hits the enter key instead of the "Buy" button, it allows the order.how to use the current code to also check for an Enter key submission.I can handle the PHP and the db lookup for minimum quantities.

Check Before Posting The Form (including A Botdetect Check)?
Jul 18, 2009I have an .asp page for my customers which does just accepts e-mail information and passes this information to another .asp page. But before passing the info, a javascript checks whether the entered e-mail does match some certain rules. Rule1: If any input has been made at all, Rule2: If an "@" sign is there, if the"." is there and so on. upon pressing the submit button, the first rule works but the second rule does not. Could not figure it out why.
[Code]...
It is the function control() which validates the e-mail field. But it just validates whether the e-mail has been entered or not. The second check (with the @ sign) is not being made.
