Is it possible to access Objects like (document.form1.textfield1) with a string variable like (var obName='textfield1') and using (document.form1.obName.value)?
Ive tried it in IE but the value in the obName is not cosidered as a object name.
Below is what I am trying to accomplish. I want to have the areas with
+txt+ to have the user defined variable inserted. I can't seem to get
it to work....
I have a for loop: Code: for( var i = 0; i < aInput.length; i++ ) I want to use this i variable to concatonate it as a string to find an input box
Code:
var j = i;
var qualname = "discountqualifier" + j;
qualname.toString();
if ( inputName == ( qualname ) )
{
Assuming I have a input box named discountqualifier0, discountqualifier1, discountqualifier2 etc...
I need to create 14 javascript Ajax objects and assign properties and events to them. Since most of the code is just being repeated, I'd like to do the whole thing in a loop using an array for the object names. This is a portion of the code as it now stands:
boxe2_tree = new dhtmlXTreeObject("boxe2_div", "100%", "100%", 0);
boxe2_tree.enableCheckBoxes(1);
// etc.
boxe2_tree.loadXML("./xml/boxe.xml",function(){loadTree('boxe2_tree');});
warn2_tree = new dhtmlXTreeObject("warn2_div", "100%", "100%", 0);
warn2_tree.enableCheckBoxes(1);

I am trying to convert some of my javascripts into a class and am
running into difficulties which i think are related to variable scope.
Basically I have a constructor function for a calendarInput class that
takes 4 parameters, the first is a reference name/number for this
input. I also have some functions for importing my PHP classes into
Javascript using AJAX (properties only. still trying to get methods
working but that's another story!). The relevant function is called
call_object_method(classname, methodname, createparams, methodparams,
post, callbackfunction). This creates an instance of the specified PHP
class using the parameters in createparams. It then calls the
specified method using the parameters in methodparams. The result is
passed back to the javascript function specified in the callbackfunction parameter (ie the value of xmlhttp.onreadystatechange is set to callbackfunction before xmlhttp.send() is called)
The function i am trying to fix is called show (x,y) which creates the
html for the calendarInput and displays it at co-ordinates x, y.
So, my code is as follows:
function calendarInput(calendarid, target, displaytarget, value)
{
this.calendarid = calendarid;
this.target = target;
this.displaytarget = displaytarget;
this.value = value;
this.show = function(x, y)
{
<!--// bunch of init and prepping code. includes creating
createparams and methodparams arrays //-->
call_object_method("cms_calendar", "getcalendarview",
createparams, methodparams, false, this.showcallback);
}
this.showcallback = function()
{
alert(this);
<!--//code to create html//-->
}
}
I know i've cut out most of the innards of this. This is because I
have already tested these functions and had the calendarInput working
outside of a class, hence am pretty sure that this is ok (plus it runs
to almost 1000 lines these days!!). My problem is that when I call the
show method, the alert on the first line of the callback function
returns the function showcallback instead of (as i was expecting) the
instance of the calendarInput object. Whilst this kinda makes sense I
can't figure out how to reference the Object instead. I have tried
'this.parent' but this returned undefined. I have tried changing the
way i reference the callback function (ie the final parameter of
call_object_method) but no joy.
I have a 'small' problem for read and write something in TD cell
i try this:
d = window.document;
eTBL = d.getElementById('tbCal');
cTR = eTBL.getElementsByTagName('td');
cTD = new Array(); // Collection des TD ligne par ligne
for (i = 0; i < cTR.length; i++){
cTD[i] = cTR[i].getElementsByTagName('td');
alert("une cellule");
}
but if eTBL is correct...... cTR.length = 0
why this $%*#@ of value is 0???? my array have 8 lines with 7 cell for each,
but the first line have only 3 cell
<script>
var arrayOne=('onehorse','onebird')
var arrayTwo=('twohorses','2birds')
var arrayThree=('3horses','3birds')
[code]....
Does not work. I would expect '2birds' but returns undefined. Probably because the typeof idArray I get from the function call is string. What is the right way to do it?

Does javascript have acces to source code of previous page when I open a

window.opener.document.innerHTML doesn't work ;(
I'm writing a debugging script and I'm passing a function an object to iterate through:
myObject = {a:1,b:2}
debug(myObject);
I'm wondering if there is any way to get the variable's name as a string("myObject"), so something like a .name property:
function debug(obj) {
alert(obj.name); // would alert "myObject"
}
Is there any way to do this?
I need to look at the url, if a variable is present in the query string.
so, if my address bar looks like:
I am trying to search over a string of text to recognize any matches.Problem is that the string of text I am search with is in a variable and I don't think its working to well when putting it into a regExp.Here is what I have.
var newMessage = /myajax.responseText/;
var previous = document.getElementById("chat").innerHTML;
var matchPos = previous.search(newMessage);

Say I had a bunch of elements with id names "id1", "id2". "id3" etc. Then say I had a function that adds a click handler such that when you click these elements it gets the id name with this.attributes[1].nodeValue;Then say I had a bunch of arrays with the same names as the ids var id1 = ["data", false, 45]; var id2 = ["otherdata", true, 15]; var id3 = ["otherotherdata", null, 65];. How would I set a variable "currentid" to the array with the corresponding name as the id name? I guess the underlying question is, how would I convert a string to a variable name?
View 1 Replies View RelatedI have a javascript program that currently takes the contents of a *.txt file and converts it to a string-type variable using a hidden iframe.
For my pruposes it would be much nicer to read a *.csv file instead, however the method I'm using creates the "open/save file" pop-up window.
All files are client-side and in the same folder on one computer; this is NOT server-side or internet-based. It is simply javascript used in an HTA file as programming code. The *.csv does not need to be edited, just read.
I need to know how to convert the text of this *.csv file into a string variable. I have heard of using "xmlHTTPRequest (AJAX)" but am not familiar with how to use this.
I'm having trouble getting a text string into a variable:

I'm using the alert to confirm if I've managed to get the time ok from the html, it should when working display the static time but currently displays NaN which AFAIK means that javascript is getting something from the HTML but it's in a form that it can't work with.
I know that the HTML validates fine, the time display is output from PHP. The intention is that PHP will output the time, if javascript is available then the javascript will take the static time and turn it into a ticking clock.
I'll look into the main guts of the clock script at another time, right now I need to get the basics working. I need to do it something like this way as I don't want to have any javascript embeded in the HTML, I want to have the javascript in external files.
I am designing a feedback page for my website and have carried info through the url to the feedback page from a previous page. This url contains a name of an individual, in between two symbols = and &
The url of the feedback page looks something like this:[URL].... First, I have used a form to display the information so that the user can see who they have selected, ie. extract the first and last names from the url. (The script following the form extracts the name from the url so that it can be displayed by the form, not exactly sure why it does so in this particular order but it seems to work so far).
This is the code I have used to do this:
<FORM NAME="SWnamefunc">
<div align="left">
<INPUT TYPE="hidden" NAME="yoyo" SIZE="35">
</div>
[Code]...
So I am receiving a string with a name and I want to turn that name into a variable name.
Code:
var strName = "Name";
I want to be able to use Name as a variable.
having trouble getting a query string/URL to append a couple of variables from a function (well, trying to get ONE working). Basically, once a user makes a selection from a form, I want the script to add the variable to the query string, which is then sent off to a PHP script. If I manually enter the 'social_housing_type' as a number in the query string, it executes properly, I just can't get it to do it from the form.

menu[i] should reference the "login" variable and then put one of the values for the login variable array in its place. So if menu is settings then the settings array would be used.
Is there a way in Javascript or Jquery to return an array of all objects underneath a certain point, ie. the mouse position. Basically, I have a series of images which link to various web pages but I have a large semi transparent image positioned over the top of the other images. I want to find the href of the background image that the mouse pointer clicks over.
View 1 Replies View RelatedI have three drop down menus that when changed call a simple js
function, passing a value i.e.
<SELECT name="Team" onChange="change('national');">

document.images.premShirt.src = "assets/shirts/"

the var 'which' is being passed succesfully, but i can't work out how

I am new to Javascript but fluent in C++ and other languages, I have a query, I made a global variable to hold string information, can the value of this string be assigned to a form input field value? I mean in the 'default value sense' I am just wondering if there is any syntax to accomplish this. EG in my javascript I have the string nameVal; It is a global variable, I would like to know if it is poosible access its value for use in the line below shown with italics, or is it basically always a case of 'type the value in manually yourself' and then rely on events functions to update the field thereafter?
Name: <br><input type = "text" name = "nameField" size = "50" value = my string val here onChange ="this.value=storeVal(this.value, '0')"></input></br>
