View 1 RepliesI have 4 checkboxes in my form and wanna change the number (to be displayed) according to the selection made on the ListBox Menu
HTML PART of the code
<select name= "rights" onChange="chk_Count(this);">
<option value = 0 > Admin </option>
<option value = 1> guest </option>
</select>
<input type= "checkbox" name = "add" value = "on">
<input type= "checkbox" name = "edit" value = "on">
<input type= "checkbox" name = "delete" value = "on">
<input type= "checkbox" name = "view" value = "on">
I want that when I select Guest onle checkboxes for "ADD" n "VIEW" should be shown and when Admin is selected all four. but I am able to find out how to access those elements in the form
and change their properties.
How can I access to specific element by javascript and not by using the getElementById method.
View 1 Replies View RelatedFirstly, I am aware of all the issues that are introduced with frame
pages - this was not my decision - it is just what I have to work
with...
I have a frame page that looks like this
-------------------
| topFrame |
-------------------
| navFrame |
-------------------
| ContentsFrame |
|------------------
Within the contents frame I have a NEW FRAME set which looks like this
--------------------
| | |
|treeFrm | frmDisp |
| | |
--------------------
I know that this is awful. I have a link in the contentsFrame. When I
move over that link, I need to get a layer that already exists in the
frmDisplay to become visible..
When are named elements written with script accessible to script?
<html><head><script type="text/javascript">
function ready() {
alert( document.getElementsByName("div").length );
}
</script></head>
<body onload="ready()">
<script type="text/javascript">
document.open();
document.writeln( "<div name="div"></div>" );
document.close();
</script>
</body></html>
IOW, why are there 0 elements named div at the time the <body>
element's onload handler is invoked? When can I retrieve this named
div from the document hierarchy?
This exercise is necessary since code I have written using the DOM
(that works) has to run on God-forsaken browsers such as IE 5.1 for
Mac whose support for the DOM is spotty at best.
I need to pull data from an iframe, everything is on my domain (no cross-domain issues). This is how the iframe is named.
Code: <iframe ID="search_frame" src="http://www.mysite.com/pnsearch.php"></iframe>
The iframe has a bunch of <span> elements in it. I need to access the innerHTML of the spans, to check for data and use the data elsewhere. Each span has an unique ID assigned to it. What would be the syntax to read this information? I've tried all sorts of document.frames["search_frame"].getElementById("ID").innerHTML variations to no avail.
However, I'm still wondering about my actual problem, which is that I need to initialize some arrays of named elements when the document is loaded so they can be used by other functions used as event handlers. What I have now is that every function that requires
these arrays checks to see whether they have been initialized, and if not initializes them. That seems to be a fairly ugly hack, and I'd like to use a better way if it exists. Does that make sense?
I'm trying to write a script for a website that reads from a database and makes a separate table for each entry in the database. Since the number of entries can change, I want to dynamically create a div for each one, which I can later hide or display based on user selection. However, when I try to access the dynamically created elements by their ID, they return null. Is what I'm trying to do here actually possible?
for(var i = 0; i < tables.length; i ++)
{
var newDiv = document.createElement("div");
newDiv.setAttribute("id", tables[i].name);
newDiv.setAttribute("name", tables[i].name);
newDiv.setAttribute("class", "hidden");

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 ?
I return json string and loop through the results putting items in Div's and want can't seem to access the class attribute / selector.
$.getJSON(strUrl, function
(data) {
var
items = [];

I'm having trouble accessing some Elements with jQuery after I created them and added them to the HTML. I want to add some Checkboxes to my Site as soon as the user clicks another Checkbox. That works just fine. But if the user clicks on one of these added checkboxes, i want an event to trigger, too. For starters, i just want to alert a message. But this doesnt happen.So, now I think the Elements are added properly to DOM tree. But still, when I click on one of the added input Elements, nothing happens.What am I doing wrong? How can i get jQuery to recognize the Elements I added?

View 2 Replies View RelatedI have a form. Upon submit, the data is sent to the server. Under certain conditions, the form is replaced via ajax with a set of radio buttons that offer the user a a choice.I need to access the radio buttons before I submit the form again.Normally I could just access the buttons with getelementbyid but it is not available, presumably because they were generated via ajax.I could submit the form just to access the radio buttons and then submit it again, but I'd like to avoid that.
View 2 Replies View RelatedI have 2 arrays:
var A1 = new Array();
A1[ 0 ] ="Y2";
var B1 = new Array();
B1[ 0 ] ="Y1";
B1[ 1 ] ="sink";
I also have a drop down menu with the names of the arrays. Say:
document.form.option[1].text returns 'B1'
Can I transform the string 'B1' into the array B1, so that:
document.form.option[1].text[1] returns 'sink'
Currently I'm doing this with conditionals, e.g.
if(document.form.option[1].text =="B1){do stuff}
but this gets a bit messy.

I am undertaking an assignment where I have to create a webpage that reads values from a database, and generate the appropriate amount of sliders (scroll bars) according to the number of database entires. The webpage functions like this: On index.php load, it reads all the slider values from the database and automatically generates and sets each slider to that value On setting each individual slider to a new value by adjusting the slider, the code automatically updates the slider value in the database via AJAX.
So far I have gotten both functionalities to work successfully. There is just one problem with the 2nd functionality. I can only get one slider value to save to the database at a time. I know how to fix the problem, I just do not know to achieve it. I shall now illustrate via snippets of code:

Can anyone tell me the best way to access a hidden object in a form? I could use a hard-coded index to the elements of the form, but it's too easy to add something before the hidden object and mess up the indexing. For example:
The form has a tagid of "myForm"
The hidden object has a tagId of "myHiddenObj"
I can get the form elements by using
var formElements = document.getElementById('myForm').elements
But there doesn't seem to be any way to do this:
document.getElementById('myHiddenObj')
Assuming I have the elements as obtained above, none of these have
worked for me either:
formElements['myHiddenObj']
formElements["myHiddenObj"]
formElements.myHiddenObj
Anyone have an idea?
I've been using some code to verify form data quite happily, but i've
recently changed the way my form is structured, and I can't get it to work
now.
Originally :
The form is called "form1", and I have selects called "PORTA", "PORTB" ...
etc...
I then had javascript that accessed these selects as below, and it worked
fine.
ind = document.form1.PORTD.selectedIndex;
val = document.form1.PORTD.options[ind].value;
dev = document.form1.PORTD.options[ind].text;
My form is now autogenerated, and form data is stored to file, so I now use
an associative array for thte form elements (so that I can loop through them
easily), The form elements names are now :
McuCfg[PORTA], McuCfg{PORTB} and so on
Now, I modified the javascript so that it now uses the McuCfg[] associative
array :
ind = document.form1.McuCfg[PORTD].selectedIndex;
val = document.form1.McuCfg[PORTD].options[ind].value;
dev = document.form1.McuCfg[PORTD].options[ind].text;
When the script runs, I get the error
"document.form1.McuCfg.PORTD is null or not an object"
I have used the same notation that i know works for the "options" array
although that's not an associative array.
If I have inputs like this:
Code:
<form name = 'myform'>
<input type='text' name='Monday_1'>
<input type='text' name='Monday_2'>
[code]...
But can I somehow do this instead?:
Code:
<form name = 'myform'>
<input type='text' name='Monday[1]'>
<input type='text' name='Monday[2]'>

I feel like I've been server-side programming so long that I completely forget how client-side works. I have a super simple form:
Code:

First name: <input type="text" name="firstname" /><br />
Last name: <input type="text" name="lastname" />
<input type="submit" value="Submit" />
</form>
Is there a way to use Javascript on "page2.html" to access the contents of firstname and lastname and display them?
Code:
oText = oForm.elements["text_element_name"]; OR
oText = oForm.elements[index];

I'm building a website that needs to be able to check the value of an
element and give it a new value based on what it's current value is.
So for example, if I had a product and my code read like this...
<input type="text" name="name" size="20"><br>
<input type="text" name="description" size="20"><br>
<select size="1" name="public">
<option value="1">on</option>
<option value="0">off</option>
</select>
Assuming the name of my form was "form", I could access the value of the
text fields by "window.document.form.FIELDNAME.value" and the select by
"window.document.form.public.selectedIndex". But the page i'm working with
has multiple products listed and so I've addopted a nming convention for the
elements name's so that I could access it more efficiently in PHP. So for
example, I'd have multiple products as such Code:
I'm, having some problems with this function.
function displayElements()
{
for (i=0;i<document.forms[0].elements.length; ++i)
{
document.writeln(document.forms[0].elements[i].value);
}
}
I'm trying to loop through the only form (form[0]?) on my webpage and
display all their values. For some reason I'm only being shown the first
value?
I have 1 form, and dozens of elements. In the select elements I use onchange="somefunc()". In this function I'd like to access and change the form element attributes (such as form.element.option[].value and form.element.option[].innerHTML).
Is there a way to access the element that has just changed (unsing onchange="somefunc()") by passing a "this.element" parameter to access the elements properties such as form.element.option[].value within the function?
