View 7 RepliesI know in different languages (VB.Net,C++,C#) how to pass an argument to function in this code:
<html>
<head>
<script language="Javascript">
<!-- hide
function openNewWindow() {
popupWin = window.open('[URL]',
'open_window',
'menubar, toolbar, location, directories, status, scrollbars, resizable, dependent, width=640, height=480, left=0, top=0')
} done hiding -->
</script></head><body>
<a href="javascript:openNewWindow();">return to front page</a>

I need to add several links in my page, so I need to pass indexes from links to main function, so I can open images in specific folder with indexes filenames. For example in vb
Subname("text_to_pass_to_SubName")
Public Sub SubName(ByVal function_text as string)
End Sub
I have a main page that opens a pop up window when the user clicks a
link. The pop up window is a menu and when the user clicks the item, it
populates a form input element on the 'parent' window.
My question is: this new populated form element is the value that I use
to change a style.
onchange does not watch this form element because of getelementbyid, so
it doesn't trigger the function needed to change the style. onchange
works fine if I just manually input a value into the text box.
Any other way to fire the function off when the user picks their
selection from the pop-up window? I was thinking I could use
window.opener.function()? But how do I pass the form from the parent
window? From the pop up window, I don't use this.form, what do I
use?something like window.opener.form[0] ?
I tried a function like that
function (test) {
var a=document.form.test.value;
}
test is the name of text fields. I doesn't work (undeclared test variable)
What I want is a loop that will call the same function until it reaches a certain number (let's say 10). Then I want the function to take the parameter passed (the number) and use it in the function where ever you see a 1 below. Basically I want it to run on each element of the pub_name array and from the info gathered define a variable based on the number (example: display_pub_name_*). I have run some tests .....

I have a function which can be called with an unlimited number of
arguments.
I want to call another function with exactly the same arguments. I know
I can get the arguments in the arguments object, and as such also in an
array, but how do you pass the elements of an array to another function
as parameters?
Is there a way to pass arguments to the callback function used inside an addEventListener? I see that I can only list the name of the callback function. For eg, I use this:
var boldLink=document.getElementById('cmtbold');
boldLink.addEventListener("click", rBold, true);
I need the id of boldLink to be accessible from inside the function
rBold()
Sorry, bad title. Anyway, is there a way to pass the arguments to an object
instantiated via a constructor using the arguments object and have it
expanded, so to speak, so that it doesn't appear as a single argument? I'm
sorry, this explanation is just atrocious, but I can't think of exactly how
to word it. Maybe an example...
Take for instance Function.apply. It takes 1-2 arguments, the first being
the object to use as the context, and the second being either an array or an
instance of the arguments object which are to be the arguments for the
function. I want to do something similar but I want to also basically use
the new operator so that I get back an object.
Here's a snippet of some of my code, maybe this will help:
I would like to display few calendar fields on the same page with different days disabled. I guess that the easiest way to do that would be to let thenoWeekendsOrHolidaysfunction take care of it but in order to do that I need to pass some values to it. How can I do that?
$('.datepicker:not(.ui-datepicker)').live('click',function(){
alert(this.name);
//var disabledDays = '12-15-2011';
$(this).datepicker({

How can I pass arguments to a function as elements of an array.[code]
View 1 Replies View RelatedUsing a simple example lets say there is this function in an external script:
Code:
function showmessage(arg){
alert(arg);
}
If we have different scripts eg page1.php, page2.php, page3.php etc
If each one of those scripts calls the function showmessage using different arguments eg page1.php calls it like this :
Code:
<script language="JavaScript" type="text/javascript">
showmessage("page1");
</script>
The above code would have to be embedded into the PHP file.
how can we go about doing that unobtrusively? Ie by not putting the code into the PHP files how can a different argument be passed to that function depending on what page is loaded?
This is related to the pop-up window. Below is the function related to pop-up window.
function openPopUpDetailsMultiple(seqNum ,controllername ) {
if (!popUpDetails||popUpDetails.closed) {
popUpDetails=window.open("GetSCEventAddData?schandle=<!.schandle>&objID=<!.objID>&seqnum="+seqNum+"&controllername="+controllername+,"popUpDetails","toolbar=1,location=0,scrollbars=1,width=600,height=300,resizable=1,left=200,top=200");
}else{
popUpDetails.focus();
popUpDetails.location="GetSCEventAddData?schandle=<!.schandle>&objID=<!.objID>&seqnum=" + seqNum;
} }
The above function is being called in the href link as stated below:
//Draw the event table
document.write("<table border=1 bgcolor=" + contrColor + " cellpadding=3 cellspacing=0 width=750><tr><td width=130 valign=top class=body align=center rowspan=2>" + scEv[i].sceTime + "<br>" + scEv[i].sceDate + "<br>" + scEv[i].sceCntr + "</td><td width=60 valign=top class=body align=center><img src=images/NsaAlarm"+sevIcon+".gif border=0 height=16 width=16 align=middle alt='" + sevText + "'></td><td width=230 valign=top class=body align=center>" + scEv[i].sceCode + "</td><td width=230 valign=top class=body align=center>#" + scEv[i].sceSeq + "</td></tr><tr><td width=620 valign=top class=body colspan=3>" + scEv[i].sceDesc + "<br><table border=0 cellpadding=0 cellspacing=0 width=100%><tr><td class=body><a href=javascript:openPopUpCAC('" + scEv[i].sceCAC + "')><img src=images/NsaTools.gif border=0 height=16 width=16 align=middle alt='View corrective actions'>Corrective action code: " + scEv[i].sceCAC + "</a></td><td align=right class=body><a href=javascript:openPopUpDetailsMultiple('"+ scEv[i].sceSeq+"''"+ scEv[i].sceCntr +"')><img src=images/NsaMoreDetails.gif border=0 height=16 width=16 align=middle alt='View more details'>More details</a></td></tr></table></td></tr></table>");
The problem I'm facing now is in this piece of code:
><a href=javascript:openPopUpDetailsMultiple('"+ scEv[i].sceSeq+"''"+ scEv[i].sceCntr +"')><img src=images/NsaMoreDetails.gif border=0 height=16 width=16 align=middle alt='View more details'>More details</a></td></tr></table></td></tr></table>");
I do not know how to send these (scEv[i].sceSeq,scEv[i].sceCntr) arguments. What might be the delimiter for these arguments.
This example is much simplified as the original script.VBScript is making a value, passes this to Javascript, which puts that value into a div tag.Now, as you see in the VBScript, the value contains a call to a javascript function. It shows perfectly in HTML, but the call can't be made when clicking the link.Is it possible in VBscript to write dynamic hardcoded javascipt function that pass arguments?
Code:
<script type="text/vbscript">
Dim m

If you specify arguments when writing a function should you still declare the argument variable inside the function?
example:
Code:
or

I'm trying to debug my expression that matches an alphanumeric with any
number of dashes (including none), except at the ends and obviously
disallowing two or more consecutive dashes.
Here it is: /w+(-?w+)*/
Test cases that I expect to pass are failing:
"01234abcdef" true
"0123-412-8370" false (should've been "true")
"asdkfjakfj" true
"0-1" false (should've been "true")
"-" false
"--" false
"-ABC123" false
"00230-" false
"ABC-123" false (should've been "true")
"1-" false
"111223333" true
Would anyone lend a hand?
I am creating a regular expression for a URL where the domain name (i.e. .com|.edu etc) is optional. That is both http://xyz and http://xyz.com should be valid. If <.> is present then com|edu|.. will be there; but if <.> is absent then com|edu|.. will not be there. Also there can be any number of <.>, but every <.> will be followed by characters. So in other words the string can't end with <.>, it should only end with [a-zA-Z0-9]. So far I have created the following part -
var url=document.myform.addr.value;
var str="^(http|https)://(([a-zA-Z0-9.-]+)*[a-zA-Z0-9-]+.(com|edu|gov|[a-zA-Z]{2})|[a-zA-Z0-9]+$)";
var regEx = new RegExp(str);

Trying to figure out a problem with the "Optional" values in a list box so I am going to keep it as simple as I can..
I am trying to calculate the optional value of a list box in stead of programming it the long way around.
I created a list box with several peoples names, like John, Sue, and Mary.
I have assigned each name a numeric "optional" values
I know the code in the list box should be:
Normally, I would code this along the lines of:
But I want to figure out how to select the Optional Value from the list, and multiply it by time instead of doing the SELECTEDNAMELISTBOX=="John" route..
I am creating an form dialog that will be slightly different for creating data than editing data. I'm pretty new to jquery, but I'm using the jqueryui and it seems to be working fine, but now I'm looking to change the labels of a couple of buttons and have one button available during editing (but not creating)....
View 1 Replies View RelatedI'm using jQuery validation on a form and I can't get it to only validate optional fields if the user enters something (should recognize the difference between this and the default value of the field, for text input fields). I know this is built in (I think) but I must be doing something wrong.
For example, phone number is optional but I want it to validate if the user enters something. Code for the phone in the JS file is:
jQuery.validator.addMethod("phone", function(phone_number, element) {
phone_number = phone_number.replace(/s+/g, "");
return this.optional(element) || phone_number.length > 9 &&
phone_number.match(/^(1-?)?(([2-9]d{2})|[2-9]d{2})-?[2-9]d{2}-?d{4}$/);
[Code]....
When I just put "phone" as the class it validates the field even if it is not edited by the user at all. For the required fields I put "required" as the class to validate them but I just read in another post that this is not necessary with the plugin...? I guess I am not sure whether the field should be define as optional by a class or in the JS file, and if it's the latter, how to do that.
I have 4 arrays that all contain data linked by the index. I have 3 drop down boxes on a web page that give the user 3 ways to search for data. The top one is mandatory the other two are optional. I've managed to create the code to search using the mandatory box but cant figure out how to expand the search.
Here is the function that deals with the search data:
function findFlights(){
var yourAirline = readTheAirline();
var result = 'Here are your flights <BR>';
var choose = 'Choose your destination';
for (var index = 0; index < flightTimes.length; index++){
var flight = flightDestinations[index];
var airline = flightOperators[index];
if (yourDestination == flight){
var b = flightTimes[index];
var c = flightDestinations[index];
var d = flightOperators[index];
var e = flightFares[index];
var message = b + ' to ' + c + ' operated by ' + d + '. £' + e + '.';
result = result + message + '<BR>';
}if (yourDestination == choose){
result = 'Please choose a destination city from the destination menu and then click Find flights again.';
}}displayMessage(result);}
In a registration form middleName field is optional. When the users enters his/her middleName, then it should validate that field. I have used the following code to achieve the above scenario, but it is not working.
$("#middleName").rules("add", {checkName: true, required: false, messages: {checkName: "Please enter a valid middle name"} });
jQuery.validator.addMethod("checkName",
function(value, element) {
var regExp = new RegExp(/^[a-zA-Z0-9s|,|.|-|']+$/);
return regExp.test(value);
},
"Please enter a valid name."
);
How to achieve the above scenario.
I'm trying to create a function in JavaScript using Dreamweaver8 such that when a user hits the ' F1' key when a text box is selected a separate "pop-up" window will open, with text of my choice.
Does anybody have any pointers or even some source code? I use ASP on my server.
I've been trying to create a function that creates objects and another function that can delete them when triggered the objects code is generated server side and triggers the function passing the object data. The object data sort of looks like this

style="position:absolute; left:0;top:0;"

I've tried a few methods I looked up but whenever I try to get them to work the way I need them they throw errors... It would be very cool if you could also get it under a div tag.
