Check If Object Exist
Aug 23, 2007Let's say that I have generated var SomeVariable = true; from server.
On client side I have:
if (SomeVariable == true) {

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.

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. Here is the page code and the Javascript code.
Code:
<a href="javascript:checkQuantity(document.form<?php echo $formCount; ?>,

Make A Button That Will Check A Radio Button Then Open A Page In A New Frame
Feb 13, 2009I have it set up so that there are three frames (frames and the use of javascript are encourage for practice) "bar" on the left with navigational options, "main" in the center where the body of the drill is presented, and "feedback" along the bottom where the feedback will appear.
My issue is that I have everything working except the form! I'm not sure how to make it so that upon clicking the submit button the feedback is presented in the "feedback" frame. This was suggested to me but isn't working, maybe I have a mistake somewhere? Or is there another way I can do this?

Check All Button Script For Use In PHP
Aug 18, 2006I'm using this bit of code I found online to do a check all/uncheck all button:
<SCRIPT LANGUAGE="JavaScript">
<!-- Begin
var checkflag = "false";
function check(field) {
if (checkflag == "false") {
for (i = 0; i < field.length; i++) {
field[i].checked = true;}
checkflag = "true";
return "Uncheck All"; }
else {
for (i = 0; i < field.length; i++) {
field[i].checked = false; }
checkflag = "false";
return "Check All"; }
}
// End -->
</script>
My problem is that if the input checkboxes look like this:
<input name="delChecked" type="checkbox" value="$itemcode">
The check all script works but PHP doesn't recognize that delChecked is an array. And if I do this...
<input name="delChecked[]" type="checkbox" value="$itemcode">
PHP reads delChecked as an array but the Javascript doesn't work.
Check All Button In JavaScript

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.
