Let's say that I have generated var SomeVariable = true; from server.
On client side I have:
if (SomeVariable == true) {
do something
}
How could I first check if my variable is undefined? Or how can I say if
some exception occures please don't report error, just continiue?
If variable is not generated from server, it will report me an error..
I 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.
View 1 Replies View RelatedWhen 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 Relatedi am trying to pass text from one select box to another select box. The logic is if 10 are added, no more passing must happen. Also if an item is already added, it mustn't be added again.I am using the for loop to check the existence of an item but it is not working: what am i doing wrong?
Code:
function PassSelectValues(){
//pass values from select boxes to select boxes
var counter;[code]....
why isn't counter incrementing at all? The alert message box does appear saying item exists but the item gets added anyway.

I have tried a lot of things already, but none seems to work.
I 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?
I have a page with two divs on it, <div id="left"> and <div id="right"> . On my page, there are times when the right div is not displayed as there is no content in it, how can I get jquery to detect that div id="right" does not exist on a page so make the width of the left div to 1200px.
This is what ive found, but im not sure length is what I should be using to calculate if a div exists or not:

I have some js code in which a click on a nav arrow causes list to be walked up or down and hilighted. Partial code is below. The problem is that when I get to the end of the list (e.g. there IS no next()), I want to skip this part of the code and actually hide the right arrow. I have no problem with the hiding part - I just want to set a flag when I have traversed the list to the last item.

In 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.
How do I check if the method of text() starts with a 1
View 1 Replies View RelatedI've got a couple of problems that I cannot figure out how to do.
1. I'm trying to create a list where clickable items are visible on a page and then when clicked they expand to read a text file and stay expanded until I click them again to collapse. I've got this partially working except when I click on the item now(machine1 for example), the item I clicked on is replaced by html/txt file(machine1_output.html). Then the links are not available unless I hit the back button in the browser. Instead I want them both displayed and I want to be able to see all the items in the list and have the items expanded too. The reason for this is I want to be able to click all the links, have them display what's in the html/text file and be able to do a CTRL+F to search for an item. Is this possible?
2. When I add a third item(machine3 below) to my list none of the items are clickable. code...
Anyone know whether it's possible to allow users to double click items of a multi-line text field? Of course, I want the double click to take them to another URL
