I would like to call a function with parameters, i.e. multiply('2','3','box1').In this example, the first argument would be multiplied with the second and written into the div with the id="box1". How can I set a default value for the third argument? => so if I call multiply('2','3') then it should automatically set the output-variable to 'box1' if not other defined in the call.
View 7 RepliesI am looking for a way to put all CSS values on my selected elements back to its default. I was wondering if anyone has maybe done this before and if not has any idea's to get me started.
The idea is that when I use for example:
The elements within .setDefault will return to its default font/color/height/width etc... so basically all posible values.
is there a way in javascript to provide default values for function variables.. for instance
In my case the problem is this, i have tables on about 10 pages that all use the same type of table that have checkboxes next to each row, indicating each row could be possibly edited or deleted. Now, i have a function to check/uncheck all by clicking the top box in the column. It works fine, but on one page, i actually have two of these tables. This screws it up though as it will check everything in the first table when i click the select all input box on the second table. I was hoping i could simply change the value for the id of the table and then pass that id instead of passing nothing.
in php it would look like this
function my_function($default_value = "hello") {
in javascript i dont know if this is possible though, it threw errors when i tried syntax similar to that.
I'm trying to program a reset button so that when the user clicks on it , the default values will be restored but the only problem is that the cells are returning undefined but are showing in the correct cells . Here is my code for that . Here , the function ResetGrid() is the problem.
[Code]...
I'm moving from php to JavaScript. What I want to do is assign a value to a variable only if the variable hasn't been assigned yet.
In php it would be:
if($variable=='')
$variable='default value'
I thought the equivalent in javascript would be:
if(variable=='')
variable='default value'
Can anyone explain why this doesn't work, or what I should do instead?
I've read a few solutions to this, but none seem to fit what I'd like to do. I'm quite new to JavaScript, so I'm trying to learn various solutions to problems and also what can and can't be done.
What I'd like to know is can you, on submit, check all the form values on a page, or indeed within a specific form on a page, for their default values, and if any still have their default values as the text within that box, clear that value.
So using some generic form values as an example, if I had a form that had three text fields Name, Email, and Phone, all by default populated by their respective names, if someone changed the value of Name to "Adenv" but left the other two, on submit the script would change the values to:
With *blank* indicating a blank field. Is this possible?
I have a form that gets automatically filled based on the values returned by my php file. Then the form elements have their values filled.
Now the problem is, I have set few additional show and hide <div> tags based on the values of some other fields. So when the form loads, the <div> tag doesnt show up and stays hidden only as the event that activates it is based on the radio button's change event function.
So my question is, as the form loads, how can I have these <div> show/hide based on the default values of the text fields on which they depend upon....
jQuery(document).ready( function()
{
jQuery(".hidden, .error").hide();
//
This only gets activated when the radio button is changed but i want this to be checked on change as well as based on initial values... How do I do that ?
jQuery( jQuery("input[name='ssc_appear']") ).change
( function()
{
if ( jQuery("input[name='ssc_appear']:checked" ).val() == "yes" )
[Code]....
I was wondering if it is possible to restrict the values of a text input box to only accept set values such as "XBC1". I am trying to make a form for a scanner so you can scan bar codes and it will auto fill the form out and have default values set so incorrect values cant be submitted into the database and mess everything up.
View 4 Replies View RelatedI'm working on a site and for my login area, instead of using labels for the textboxes, I wanted to just put default text in there.
The JS that I am using is supposed to only enter the default values in the textboxes if they are blank. Unfortunately, I think the JS runs before the browser puts the "auto remember" stuff into the boxs, so the JS will always put the default values in the boxes.
The problem is that, when its time for the browser to enter the auto remember stuff, it sees that there is already stuff entered, so it doesn't enter the previously-remembered login information.
I'm pretty sure that what I'm trying to do is possible, but maybe I'm going about it the wrong way. Could somebody suggest the appropriate way to do this? code...
I have to add some technique which will solve the following problem. A form is presented to the user in our web application. Say it has
4 text fields,
2 radio buttons (Yes / No)
1 checkbox
1 select list.
Now 2 textfields are pre-populated, one radio button (Yes) is pre-selected, checkbox is not checked, one option from select list is preselected.
Problem:
In 90% of the cases, all that the user needs to do is enter values in the 2 empty textfields and click Submit.
However, the user might change the values in the preselected controls, like check the checkbox, change radio selection from Yes to No, select a different option from the select list, change the default values from the prepopulated text fields.
Now in such a case where 'default' values are changed, I need to show a alert or a popup layer to the user when the submit button is clicked.
Showing a popup layer or an alert:
The popup layer/alert will be a confirmation popup which will say something like -
"You have changed the default values for:[all the fields which were changed by user]. This requires you to do [some task] once you submit the form.
If you do not wish to change these defaults, click Cancel.
To proceed with the changes, click OK and then Submit."
Clicking OK:
If user clicks OK, then all is well. User will click Submit to submit the form and do some task which is required when defaults are changed.
Clicking Cancel:
If user clicks Cancel then the defaults should be restored. User is now free to click Submit. Code:
Recently I decided to branch out and learn some Javascript on my own. I'm getting the following error: Uncaught ReferenceError: array is not defined
I don't quite understand why I'm getting this error, as I've created the array in the function showPrompt and it seems as though it's being passed around correctly. However, I believe the problem is with generateBoxes, specifically this part here:
onclick=\"getValue(array, i)\"
(line 39)
Removing array from the function parameter seems to make it execute, but beyond that, i'm lost to what is wrong.
Here's the code:
function showPrompt () {
Obtains user input
var array = new Array();
var box = prompt("Please enter number of boxes","1");
[Code].....
Code:
<script language="javascript" type="text/javascript">
function open_win2(var)
{
window.open("link.php?variable=var","Page","toolbar=no, location=yes, directories=no, status=no, menubar=no, scrollbars=no, resizable=no, copyhistory=no, width=545, height=600")
}
</script> .....
I need to use an equivalent of the php function
array_count_values()
I'm trying to trap a user entry that cannot be found in the database. When a code is entered, the page should give a "Code Not Found" message if it is an undefined value.
However, it didn't; and it always shows the "undefined" value to the page instead.
Here's what I actually did:

Is there any way we can watch variable values inside javascript functions while running through the debugger. I am using javascript along with ASP.net on Visual studio 2010.
View 2 Replies View RelatedI totally understand that in order to learn javascript I need to know how functions work, I understand the basics of passing in parameters and then calling the function with the values to maybe add something together etc I ve read countless articles about functions as well as books etc but I just dont get how they are used and when they should be used etc, the more advanced functions that have maybe 4 parameters and are doing different calculations and returning various values that get fired back into the script just totally confuses me.
What I would like to know is first of all how can I overcome this confusion and also any words of wisdom you may have. I will also add that I have no prior programming experience and have spent the last 2 months frequently hitting my head off a brick wall as I just cant understand javascript.
I have written a number of functions designed to return frequency data on 1000 randomly chosen numbers using different math functions for the rounding. I would like to include all of these functions within the wrapper of another function so that only one call is needed to get returns from all of the 'inner' functions. However, while each of the functions works in isolation, the moment I wrap them in another function they stop working. :confused:
The following code is one of the functions 'frequencyWrapperOne' that has been wrapped in the function 'testWrapper'. A call to testWrapper does nothing.
function testWrapper()
{
function frequencyWrapperOne()
{

$(something).split(something),this is a function with a function as a property for that function.

I have a list of products where they have minimum quantities in a hidden input. Some products have multiple colours, though the same minimum quantity and I'm trying to implement a jQuery check that entries made are at least equal to the minimum.
Blank or '0' entries are fine but if it's below the minimum quantity it should set to the minimum.
HTML:
Is there something obviously wrong with this? It isn't performing the minimum check and I'm really not sure why.
In part of my form, I have 3 inputs (one textarea and two text inputs),I am validating their value format using AJAX (each input triggers error message on its label in case format is wrong). Also I have one button, "NOT submit button" (type = button).Now, when clicking on the button it must enter the value of those three inputs in my database in case they are true then all inputs values must be cleared. In case AJAX validation is wrong and in case the user clicked on that button, the value of fields must kept as it is.
Actually I can not use submit button because I have it for the whole form and what I am taking about is a part of the form and it's not possible to make nested forms as I know it violates html rules. It's easy to make it if I am taking about submitting button as I can view session values on fields after submission in case ajax returns error.I can clear inputs from Javascript, but it will be cleared on both cases if AJAX validation true or wrong. Each input field has AJAX Error message that will be triggered when the input format is wrong.
I have a form that gets values that a user has selected from a list menu field, that end up like this added to the URL:[url]
Instead of the Field being mentioned more than once, how can I have it where it could mention the field once with the values coma separated eg:[url]
Would I use JS to change the URL? or VBscript?
I built my company's website and the content portion of the site uses
text with styles with relative values and the navigational part of the
site uses text with styles with absolute values. The purpose of this
was so that the end user could increase the size of the text on the
webpage and only the content portion of the page would scale or resize
but the navigation would not. This works as expected on a pc but the
entire page scales on a MAC. Does MAC not support text with styles the
same as pc so that the only scalable text is that with relative values
(ie: small, x-small, medium, large, etc)? Absolute values conist of
point sized text. Code:
