Referencing A Specific Form Object With A Common "name"
Apr 2, 2009
This has really got me stuck. Below is a distillation of my problem:
This is my function:
function Clear(form) {
???.checked = false;
}
<form name="myform">
[Code]....
How do I execute the function to clear the checkbox the moment it is clicked? How do I reference that specific checkbox, when there are multiple checkboxes with the same "name"?
The rules (the above is a simplified version of my actual problem. There is much more to my script, which means other possible solutions cannot be considered):
1. I am aware of onclick="this.checked=false", but I cannot use it.
2. The ID for the checkbox is dynamically generated, whereas the entire onclick command must be the same for all checkboxes.
3. All checkboxes must have the same name, and the name must have square brackets.
4. "this.form" must be in the onClick, as it is used by the rest of the function.
Usually I have various JavaScript functions for common functionality on my pages (i.e. select all, export, etc.). Typically I will create a common.js file and place these functions within it. Is there any advantage to create a client side object which encapsulates this functionality such that I'd use something lik common.SelectAll() or something similar?
Not sure if there is a best practice peeps follow for this or not.
if i have this code: <form><input type=text name="id1"></form> then with javascript i can reference this with this.form.id1, how can i reference something like this:
I have a table which I would like to be highlighted with the click of a button, but I can't seem to reference it correctly. I can make the <td> clickable and function, but when I try to apply it to the button I can't make it reference the td cell, rather than change the background color of the button.The function is:
I have created an object called list. the object has a method called load and a method called setSelected (it has more, but they arn't impotant here).
The load method prints out table rows like this:
str+="<tr>"+data+"</tr>";
and in the end, inserting str as the body of a table.
what I want to do now, is have an onclick event for each of these table rows, that calls the setSelected method of the current object. so for example, if I'd write this on my page:
mylist = new list(args...); mylist.load(); <div id='associated-div'></div>
that if someone clicks a row in the table that is created in the div, the setSelected method of my list oject will be called.
I'm trying to build a simple "where's the meeting room" page for my work. This consists of a background image of the map, and (right now), a red block absolutely positioned on the map to show where the room is.I'm using an object to keep track of x/y positions for the rooms, i.e.
Code: var rooms = { a123: { x: 100,[code]....
This works, but uses eval() a lot, which doesn't seem like best practice. What's the appropriate way to get the info?Here's the whole page code:
whenever I run the below code I am unable to hide my <DIV>. I have posted a previous post regarding hiding DIVs however as this is slightly different I thought I would create a new topic here to allow for easier searching for other users.
The below code works if the DIV is outside of the form however if I enter it within the form nothing happens.
i have a simple thing that causes me all sorts of headaches. I have many forms on the same page, and identical items in each form. The same object in each form call the same procedure. So, I'm passing in the form value, such as:
onchange="DoMyFunction('formName');" and then in the procedure i do: function DoMyFunction(formname){ document.[formname].object.value='1'; }
Now i have functions like this all over, problem is getting them to work. Once they work, they work fine. But when i add a new one, it can match an old function (except the object being referenced) and it won't work!
Does anyone know the proper way to reference a form in a function?
I have validation code on my web form used by passing in the name of a field on the form. I have fields on my form named Hospital1, Hospital2, Hospital3, etc. I am trying to write a For loop to validate each one:
with (thisform) { {for (i=1; i<=9; i++) {
[Code]....
What is the proper format of var vHosp= "Hospital"+i; so that it will recognize that field?
I am using the following system to create my forms : <% using (Html.BeginForm()) { %> Now I want to refer to the form in JQuery, but all the examples I can find refer to the form by it's name. How do I refer to my form if it doesn't have a name?
I am experience some problems reading a form variable from a Javascript function. The point with this particular variable is that its name has the following syntax:
<input name="tx_impexp[tt_content:159]"/>
I want to set this var to 1 from my javascript function, so I tried to execute the following line of code:
Error: missing ] in index expression document.frm_1.tx_impexp[exclude][tt_content:159].value=1 --------------------------------------------------------------|
It seems Javascript expects to close down the bracket at the position marked...An easy solution would be to change my var syntax but the point is that I cannot since I am using an already made script and I should not modify it.
Just wandering if this is due to a syntax error defined according to Javascript specification language or there is something wrong with this.
I'm trying to create tooltips for a Drupal form that was built with the Form API. I'm able to show and hide all of the description fields on the form using the following method
I want to be able to set a property on a private object by giving the not notation path to the value. The difficulty is that this object is within closure so I can't access it directly to set the value the normal way (eg. dot.notation.path = 'new value'). This seems weird but I can't think of the obvious way.
Example:
// setter function function set(path, change){ var privateObject = { a: 'a',
One of the great annoyances I have with JavaScript is the lack of a good consistent code library. Oh, there are a few code libraries scattered around for doing various things. The problem is that each of them have their own way of doing things. If we want to use more than one library at a time, we often end up duplicating code and working with different interfaces and practices that aren't necessarily compatible with each other...
So... isn't it about time that we have a Common JavaScript Framework?
I'm thinking of a standardised code library, mostly (but not entirely) built from the free code that is already out there. (I'm thinking of a LGPL core with independantly licensed extensions.)
I know of a few very cool projects that aim to make JavaScript development easier, more professional and to bridge the gap between browsers and environments. (To name a few: DynAPI, DOMAPI, Sarissa, 13th parallels' library, netWindows, bindows, ActiveUI, f(m).) But I don't know of any effort to bring all of these features into one common framework. Can we do anything about this?
I'm not exactly proposing that we form a group to design and implement a complete framework. I just think that, us, JavaScript developers should talk to each other more and agree on a few things. Then, I imagine being able to access this centralized, well designed library that is ready for serious (and less serious) development and the dream goes on...
I have been working with JS (client and server) for some years now and I'd like to bring more consistency to my code and spend less time writing lower level code. So I may be writing this email more out of wishful thinking than determined action. In any ways, I remain interested to support any effort that would lead me to better, well designed, programming.
Is there a way to place a code that will be executed any time any button is pressed or any hyperlink is clicked? I don't want to write or call this code on every button press. Something similar to java's base class functionality that is extended by child classes? In my project ,I have to manage users to access my app - and if a user is deleted and that same user is having app open in one of her browser windows and she performs any action,she should be redirected to login screen.
I am thinking of writing a code that will check if user exists in the db or not and then put it in javascript file at a common place so that it gets executed everytime user presses a button(or does any other action). I am using jquery and Direct Web remoting framework in my app.
what character occurs most frequently in a textarea. Do I really have to store every single character in an array and then sort it? Is there a Regular Expression for this?
I have a problem in accessing all elements with a common id name in ExtJs. In fact, I have a couple of divs with id like:divmic+a number.
That is the code:
Code: <div id="slideshow" > <% for i=0 to 660/23 for j=0 to 380/23 Response.Write "<div id=divmic" & i & j & "
[Code]...
If I try this code, what is inside of "each" instruction works, but if I want to access all those elements having id starts with "divmic", it doesn' work. Why it's happen that think and how to put all those elements into an array, in ExtJs ?
when the user submits a form whose fields have not satisfied the validations, then how can we display a "message" saying that "please fill all the fields appropriately"? And also that message should disappear when the fields are appropriately filled.
