We use .mac's to create some of our Web content where we also use some javascripts. We have numerous prompts where we have a button for the user to click on that brings up a new prompt window where they type in a search name like, TIE, to search for all ties available to select from.
After typing the search name, the same window displays a list of selections to choose from. When they select the desired item and click the continue button, the window closes and we return the item number to the calling program.
What I would like to do is bring back more than one variable. For example, instead of just, 1234 in Fld1, I would like to return, 1234 into Fld1 and B into Fld2, where Fld2 will not be displayed but needed elsewhere.
For this made up example, these codes could stand for... 1234=Tie and B=Blue. We may use 1234 for all ties and have a second field to further define it.
The code I have always used in the past will just bring back the 1234, I am asking how to return the B also?
Here is some of the code I currently use:
This displays the button they click to bring up the pop-up search window...
So for whatever reason the convertToArray function in the following code returns false if the argument is more than 1 character long. If it's 1 character long it just returns the character as an array with only one value.What I'm trying to do is take a string of numbers, plus signs, and minus signs and convert it to an array.
I am wondering about what seems to be a particular quirk in Javascript that does not allow form event listeners (e.g. "onsubmit=...") to work properly. In the code below, I would like to set up a function (doOnSubmit) that is called when the form is submitted.
But there is a "return false;" in the "onclick" of the button. If this "return false" is removed, the code works as I would hope it would. With it there, doOnSubmit is never called. Code:
On this page I'm given the impression that stopPropagation is a lot like returning false:
http://www.brainjar.com/dhtml/events/default3.asp
"preventDefault() Can be used to cancel the event, if it is cancelable. This prevents the browser from performing any default action for the event, such as loading a URL when a hypertext link is clicked. Note that the event will continue propagating along the normal event flow.preventDefault() Can be used to cancel the event, if it is cancelable. This prevents the browser from performing any default action for the event, such as loading a URL when a hypertext link is clicked. Note that the event will continue propagating along the normal event flow."
But often, if I want to stop a hyperlink from working normally, I can simply return false from whatever action I've attached to that hyperlink. Suppose I have this link:
<a id="link1" href="index.htm">link text</a>
Suppose I attach the function "alertDanger" to this link:
function alertDanger() { alert("Danger!"); return false; }
Because I return false, the default behavior doesn't occur. Would there ever be a benefit to doing this instead:
function alertDanger() { alert("Danger!"); preventDefault(); }
Perhaps preventDefault is only for those occassions when the code can not or should not return?
I am building a page with a member login system on the home page. I right now have it so that if the user does not enter a password or username it will change a div to block style and show the error at the top of the page. Is it possible to after 5000 msec after returning false to the form, to hide the div again?
User Does Not Enter Username/Pass Submit Button Pressed Error Div Is Shown Form Results False 5000msec Wait Error Div Is Hidden
I have been trying for a while, but I either have it disappear and the form takes 5 seconds to get its result, or the form returns false and the div does not disappear.
I have a simple example below showing how when I pass in the value of the value attribute of option node, and then use if operator to check whether parameter is a string or not, even though it's a string, it converts it to false boolean and triggers the else statement rather than calling a function.callback should be a string so why is it saying otherwise?

I am trying to dynamically open a popup window but ie8 blocks it with the popup blocker. basically within a ajax fuction I have a confirm button and if the user clicks yes it opens a popup window. now I tried it with a javascript function but it got blocked, so I have tried it by creating a form with a button in it and instead of calling the popup function direct I call document.form.button.click and in the form my button has onclick"popup('<? echo url; ?>')" but this also is detected as a unwarranted popup and is blocked.
now I understand that the popup blocker works when a popup is called without user interaction, but allows popups on say button clicks. how can I get the popup to work

I have a couple of utility windows - a calculator and a calendar that popup from my main window. I would like them to always stay in front of the parent window until they are shut down with there own close buttons. As it is, when you click back to the parent window, of course it comes in front of the child windows. Can I do this?

I have the params in an input box and need to get the val of the box into a param and pass it to the new popup window. All pages are local and in the same folder.

I am trying to insert the value of a variable gathered from a popup window as an option in a <select> menu on the main window. This is the code I have so far:

How do I do the rest? I just want to add this new value to the end of the list.
I need the most efficient way of passing a variable from a parent window to a popup window.The reason i say "most efficient" is because i currently do it like this from the parent:[code]But this is inefficient because at times it randomly alerts "undefinded".Anyways, can someone tell me a more fail safe way to pass a var to a popup so that i will be able to access it 100% correctly.
how I can populate the value of an input field on a parent window from a selected item (of a form - listmenu) on a pop-up window? Basically, I need to pass the value of one form to another form located on a different page...
I have a popup window that comes up when a user doesn't have access to a certain page within my site. The problem is when a user clicks on something the popup window comes up but the bigger sized window of that popup comes up in the background as well. I am trying to have my popup window come up while the original page I clicked from is still focused/seen in the background. This is the code I currently am using, can anyone help me with what I am missing. I have a back button but I won't need that if I want to maintain the original page in the background. Instead I will use a close button.
