JQuery :: Empty Doesn't Check Values After Loading
May 7, 2009
I'm trying to select my textarea only if it is not empty. I have used :empty for this purpose. This works find when you load the page, however if you start typing in it still considers the value as it was when the page loads.
Example. If my textarea is empty when I load the page, it will consider it empty. If I starting typing in, and check if it is empty it still say it is empty.
The same vice versa. If my textarea has text when the page loads, then i clear that data, it still consider it filled not empty.
I'm wondering how to check if load() is empty because if it is, I do not want to show()
$("#orderList").load("OrderListHandler.ashx?action=" + action + "&oid=" + sid +, function() { // if nothing came back from the ajax request to .ashx, then I need to hide() $("#noOrdersContainer").show(); });
I want to prevent submitting a form if any of the field is empty. also if possible I would like to validate some basic things. All I want to use JQuery: How do I do that? I have no way and google points me to plugins. The things I want to do are lightweight and I don't need plugin Here is my form:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <title>Login in Site</title> <link rel="stylesheet" type="text/css" href="/loginsys/site.css" /> [Code]...
I need a simple script that will check onclick if the user has entered something into the input text form. If they haven't then just alert that you must enter something to search for a term. I had something like this before, but the problem I was having was that it was alerting but right after you click okay it would continue on to the next page... Which kinda make the whole alert thing pointless... Also, I'm about sick in tired of not knowing JavaScript, where is some great sites to get my learn on?
I am trying to check and see if three fields are empty and if they are then to alert the user saying to fill in one of the three fields. I tried this:
if (StreetNumber.value.length == 0) { if (StreetName.value.length == 0) { if (City.value.length == 0) { alert("Please enter a street number, street name, or city.");
I need to check if a span is empty but every attempt at doing this has failed. This is in a for loop so it has to be able to change the span its checking.
var ids=new Array('PSN','XBL','xfire','steam','tweet','fbook'); for(i=0;i<=ids.length-1;i++) { if (document.getElementById(ids[i]).innerHTML == '')
[Code]....
Never runs... I have tried a few other things I've found on the internet but they don't see to work either.
I've debugged this and found out the code stops running on this line.
if (document.getElementById(ids[i]).innerHTML == '')
I have a contact info form with about 16 fields. I need to hide a subset of fields for address when the end user either (1) tabs out of the subset group, (2) clicks anywhere outside the subset field group.
I do not want to hide the fields when the end-user is tabbing within the subset of address fields, yet the focusout handler is triggered when it shouldn't be.
I'm doing a registration system and as you can see when i verify the fields, if it's empty it says that the FIELD_1 misses. And what i want is if the field is empty says that and then goes back, but i don't wanto the info already written disappears.I'm using ajax, i never worked with it, so i'm gonna ask you if i'm doing everything ok:registration form:
anotherVar should be -1 if there are no matches, but it doesn't seem to work var string = "abadafa"; var matches = string.match(/a/gi); //doesn't work with /z/ for example
var anotherVar = matches.length || -1; The default operator should return the second value if the first is null or false, and according to try { alert(matches.length);
I'm trying to figure out with Java Script how I would have Java Script check and see if a check box is or not empty. The goal is to only allow the user to have one box checked at any time in a form. That means, if they click on another one and there is already one checked, it would uncheck the one that was checked and make the one that the person checked on next checked.
how I can implement the following using jQuery 1.3 and whatever plugins may help. I need to insert an iframe or img that links to an external resource onto a page, and if that iframe or img does not load within a certain period of time, remove it and insert one that links to a local resource instead. how to check if the iframe or img is done loading.
I have a problem in asp application validation. My textbox only accepts numeric value.It should not accept empty field and negative values and charcters.I am not aware of IsNan function.
My problem arises when I use this to access the portfolio section. The portfolio section doesn't seem to work. If you head over to http:[url]... , you can see how the section should render and how a person can use the scroll feature, however, when the content is loaded using jQuery, it doesn't function properly.Additionally another problem i'm realizing is the delay of the content. For example, if you are on the contact page and then click on downloads, the content will slide left and then slide back right when the content is loaded. However the problem i'm seeing is the delay in the content loading meaning that the animation will finish and the content will then load.A second or two delay. I've tested it in multiple browsers and seeing the same problem. Surprisingly the only browser i'm not seeing this in is IE6.
I've got the following code (from this tutorial:[url]
thisItem = $(this).attr('rel');
Then I create HTML for navigation:
And it works perfect but only when I use single category for rel="". In this case rel="abc" works and rel="abc abc2" doesn't work.
There must be something with $('.pf_item li[rel!='+thisItem+']') but since I don't know jQuery I can't solve it myself. I just want to change this line into something that is able to work with multiple attributes in rel.
When submitting a form, I would like to check the values of some fields first. These fields are dynamically generated by javascript after the page has loaded (that is, a user selected a value from a dropdown between 1 and 10, if 2 is selected, 2 inputs are generated, if 7 is selected, 7 inputs are generated etc). I think I understand that Jquery isn't aware of these items because they were created after the DOM was scanned. Is there any way I can 'refresh' jquery to make it aware of these new items?
From: <input type="text"id="from"value="03.10.2010" size="12" /> do: <input type="text" id="to"value="09.10.2010"size="11" /> <input type="submit" /> --> I tried to do it with function ".val();" but value are keeping steady. It can be done any other jQuery function?
I have a form where I click a button and it duplicates the inputs thus now having X of the same inputs. The input name looks like so: <select id="select" name="cs_quantity[]"> Is there a way I can check the all values of the quantity before submitting the form? I want to make sure they've chosen a quantity other than 0.
I am very new to JavaScript / JQuery... Need to iterate over the following segment of code and either return an array or single value the e-mail addresses assigned to these labels (these are hardcoded as the check boxes values):
