JQuery :: Using .insertBefore() - Simple Data Entry Page - Enter The Name And Type Of An Animal ?
Jun 12, 2011
Im trying to get the hang of it. I am trying a simple data entry page, where you can enter the name and type of an animal (eg Freddy the ferret) and it will be added to an HTML table.
The bottom of my table looks like this...
...and I have the following in the <head> tag of the page...
The way I thought this should work is that the first bit of the line would create a new DOM element, consisting of a <tr> with three <td>s in it, the first and second of which would contain the values the user entered. This new DOM element would then be inserted into the table right before the last row.
The problem is that the values from the two <input> tags are ignored, and a row with three empty cells is inserted...
I tried adding the following to the script...
And this showed fine, implying that I am getting the values correctly.
I even tried hard-coding the whole line, but that still added empty cells. Oddly enough (to me anyway), the space in the third cell was recognised, but the hard-coded text in the first two cells wasn't.

I have designed a data entry form in HTML. In all I have upwards of 16 data entry elements (varying from edit boxes, '<input>', drop down controls, check-boxes, etc)
I know by setting the tabIndex of every data entry element user can navigate easily with the Tab key. But, even if it is non-standard, can the navigation be done with the 'Enter' key instead (it is the users, non functional requirement)

I am using a very simple search-type page to enable users to input a model number and its page appears in a inline frame. Its not a true search as it is simply relying on a person entering the correct html page name to find it. But this works perfectly in my application.The problem I have is that I cannot get the type box to accept enter key as a submitt, only a click of the mouse will submitt the request. If enter is pressed the box loses the users input but no action is taken.I think this may be a javascript issue. I have posted the code below.

I've done a fair amount of PHP development, but am new to Jquery. What I'd like to do is develop a tablet web app that uses custom image buttons for numeric-only data entry to populate form text boxes. Basically, when an image button (0 - 9) is tapped by the user, then the text box having the focus gets that corresponding digit added. There will also be a "back" button to erase, and a "send" button to process the form. It looks like this should be possible to do using Jquery or Jquery UI, but again I'm a newbie with Jquery and am not sure how to proceed.

i'm loading an external web page (i.e. google.com, espn.com) into
an IFRAME on top of a web application we have running in IE running on
a kiosk. the kiosk is only a touch screen and has no hardware
keyboard.
i'm looking to create a software keyboard that can be requested by a
click on our web application (a web page for all intents and
purposes). the windows accessibility keyboard would be ok, but when
opened from the browser you get the 'confirm opening an exe' dialog,
which ain't cool.
so next i was hoping make an html/flash keyboard
which would talk to the forms within the IFRAME via a javascript
layer. however i later found that javascript is not permitted to
access the contents of a document within an IFRAME loaded from an
external web site. so there is no way for javascript to directly
modify the text values of the form elements.
so now i'm stuck....i'm limited to solutions above the IFRAME
level...is there a way to programmatically mimic a keypress and send
it to the browser from within the browser? any other ideas?

I have come in need of assistance in guiding me in the right direction. My intentions are to create a web-based page where one can select from a few drop down menu's, and enter a few select pieces of information. This information would then be logged for later purposes, when the user chooses to retrieve this information (during the initial usage, no long term storage) in the format of a report.

I have an ASP page that displays, along with other data, a list of items that refer to a specific element in a database. Instead of adding an Add button, I would like to display a text box below the last item in the list to have the user input any new data. Once they enter the data and hit Enter, the data they enter should then be added to the list and another text box added beneath this item (just as forms and tables in Access do). However, I'm not sure how to implement this functionality.

My code snippet is here:[URL] I'm basically rewriting the attr properties and wrapping an image in a table to dynamically add a caption from the alt text. IE7 Error: Line 102, Char 276, Error: unexpected call to method or property access, Code: 0I looked in the minified version of 1.4 and line 102 is insertBefore. I am using it in relation to a table. Is this a know issue? is there a simple workaround? Renders fine in Firefox and Safari. Haven't tested on IE6, but I dont really care about that browser.

I am trying to create a web page in which the contents of one selection list
depends upon which element in another selection list is chosen, but where
the information to populate the first selection list comves from an SQL
database on the web server.
There are a couple of these situations in my application but, for example,
the first list might be a list of counties, and the second list a list of
states/provinces. Obviously the names of counties depend upon which
state/province is chosen, but there are too many possibilities to be able to
embed them within the web page itself. So when the user selects a
state/province I need to go to the server to ask for the list of counties.
I have seen a number of posts that sort of address this issue. For example
it is suggested to use <script src="a URL"/> to ask the server side code to
send up data of type "text/javascript". However the examples do not seem to
address how the server side code would know which state/province the user
had selected.
If there is a web site that addresses this sort of thing, I would appreciate
any pointers.

I have a textbox on one of my forms that is used to accept a time from the
user. I need to write this value to a database to trigger an event later on.
What I'd like to know is...
Are there any functions in javascript that can convert different time
formats to a known format (24 hour clock)... 5pm -> 17:00 or 5:00 to 05:00,
etc. ???
Assuming that I get the input into a 24 hour format, how can I create a full
time/date variable with todays date and the users entered time?
Finally, if the entered time is earlier than the current time, how can I
create the above date/time combination using tomorrows date?

Currently I have this web database app that I wrote in which I have a page with 3 tables. When I want to enter data into the table I currently select the table name from a drop down list and then have a javascript window open containing a form. The form is processed using php and oracle. The parent window which is the page containing the 3 tables then gets reloaded and, behold you can see a row contaiing the data underneath the choosen table. Have a picture in your mind of my setup?
Ok, what I would like is to try and eliminate the popup window. On each of the table headers I would like to have a button that when clicked, adds a row of input cells, say 6 for example . They should be able to have as many rows as they want. I would also like to add a submit button and a remove row button. And that is it.
From there I can handle the input of the multiple rows with php arrays and array splice to get the indexing I want. That is no problem. I have just never done anything dynamic and have very little javascript experience.

A while ago I wrote a "Vector data type" script
using DOM interface to select.options.
That was a (beautiful) mind game :-) rather than
a practical thing to use.
Here is another attempt open for criticism, this
time dead serious. I really need an effective
Vector emulator for a project (as much effective
as something not implemeted in language but
emulated by means of the language itself is: a
productivity impact is imminent, the question
is to minimize it).
<html>
<head>
<title>Vector constructor</title>
<meta http-equiv="Content-Type"
content="text/html; charset=iso-8859-1">
<script>
function Vector(arr) {
this.$_$ = arr || new Array();
this.length = this.$_$.length;
this.add = Vector.$add;
this.remove = Vector.$remove;
this.toString = Vector.$toString;
}
Vector.$add = function(m,i) {
if (('number'!=typeof(i))||(i<0)||(i>=this.$_$.length)) {
this.$_$.push(m);
}
else {
var tmp = [m];
tmp.push(this.$_$[i]);
this.$_$.splice(i,1,tmp);
}
this.length = this.$_$.length;
}
Vector.$remove = function(i) {
var ret = this.$_$.splice(i,1)[0];
this.length = this.$_$.length;
return ret;
}
Vector.$toString = function() {
return this.$_$.toString();
}
// Create new vector and use it as a wrapper
// over Array argument:
var v = new Vector([1,2,3]);
// add(newElement, atPosition) method
// if no atPosition provided, newElement will
// be added to the top
v.add(4); // add 4 to the top
// Add 3.5 atPosition 3
// The element currently located at v[3] and all elements atop
// of it will be moved one position up
v.add(3.5, 3);
// remove(atPosition) method
// Elements currently located atop of it will be moved
// one position down
v.remove(1);
// toString method is overloaded so in string
// context it gives comma-separated vector values
alert(v); //1, 3, 3.5, 4
</script>

oes anybody know of a good reference document/source for data types that you can pass to a function, please? What I want to establish are the variety of elements that can pass data to a function in the following way:If you set a value to a table cell (<td>) then you retrieve it in the function thus:
function(row) by calling function(this).
I know that divs and spans can do this too, but how about images in a loop with unique names etc?

I realize this script and I do not know where to begin:
1) A simple grid rows / columns.
2) The first column contain an input type = "checkbox"
3) When select the input type, the line should change color than the other rows, and you should open a popup window.
For points 1, 2 you are OK. Point 3 is the difficulty.

I'm working on a greasemonkey script that requires me to append a tag before each instance of a tag with a specific class name. It works when there's no parent tags but when it goes into levels deep it doesn't work. So how can I use insertbefore?

Here is a code:

I have a website with a lot of jQuery effects and functions which is not working properly under Internet explorer 8 and below, it works excellent on Chrome, Firefox, Opera and Safari however, I'm planning to make a light version of the website for Internet explorer, is there a way to verify browser type and version and redirect the user either to the light or normal version of the site according to those parameters?

I'm attempting to implement some deep-linking in my simple AJAX application by setting location.hash, and I've run into two problems:
1) Sometimes setting location.hash seems to send the window on both IE and FF to scroll to the top of the page. I do not want any scrolling to occur. The location.hash change happens in a function which is triggered in an onclick event.
2) Changing location.hash creates a history entry on FF (not on IE)... that's pretty cool for FF, but in this case I do not want a history entry created. How can this be avoided?
I found an example which seems to have avoided both these problems, but cannot decipher the pertinent code: [URL]
